BACKBONE OF CYLINDRICAL CELL MODULES

In the ever-evolving world of energy storage, cylindrical cell modules have emerged as a pivotal technology, offering a reliable and efficient solution for a wide range of applications. From portable electronics to large-scale power systems, these modules have become indispensable in our quest for sustainable and efficient energy use.

The journey of cylindrical cell modules began with the invention of the practical battery by Alessandro Volta in 1800. Since then, the technology has undergone significant transformations, with the advent of cylindrical cells in the late 20th century marking a significant milestone. These cells, with their cylindrical shape, offered improved structural integrity and uniformity in performance, which were not fully realized in their flat or pouch counterparts.

Cylindrical cell modules are designed with a meticulous attention to detail, ensuring good performance and longevity. The construction typically involves a cylindrical can made of aluminum, steel, or a similar material, which houses the anode, cathode, and electrolyte. The anode and cathode are wound together in a spiral configuration, big the surface area for improved electrochemical reactions. The electrolyte, which facilitates the flow of ions between the electrodes, is carefully selected to ensure safety and efficiency.

There are several types of cylindrical cells, each with its own set of characteristics and applications. The more common types include:

Lithium-ion cells: Known for their high energy density and low self-discharge, these cells are widely used in consumer electronics and electric vehicles.

Nickel-metal hydride cells: These cells offer a good balance of energy density and cycle life, making them suitable for applications like power tools and hybrid vehicles.

Lead-acid cells: Traditionally used in automotive and backup power systems, these cells are cost-effective but have lower energy density compared to their lithium counterparts.

California Barrel Cactus (Ferocactus cylindraceus)

Family: Cactus Family (Cactaceae)

IUCN Conservation Status: Least Concern

Native to the western Sonoran Desert and eastern Mojave Desert in northern Mexico and the southwestern USA, the California Barrel Cactus grows in dry, sandy soil and typically inhabits scrublands and “forests” of Joshua Trees (the only tree species found throughout most of its range.) Members of this species typically grow in a cylindrical or spherical shape and are covered in a large number of long, thin spines (which, as is typical for a cactus, are highly-modified leaves and serve to protect the cactus from herbivorous animals) which can be used to estimate an individual's age: newly grown spines, which are made of living cells, are deep red in colour, but as the spines develop the cells that make them up die and they become harder and grey in colour, so if an individual has a large number of red spines it is likely young while an individual with entirely grey spines is older. Like almost all plants California Barrel Cacti are photoautotrophs (meaning they are capable of producing nutrients through photosynthesis, a chemical reaction between carbon obtained from the air through tiny respiratory pores on the cactus’ outer surface called stomata and hydrogen obtained from water taken in through the plant’s roots), and like many plants adapted to life in warm, arid conditions they exhibit CAM photosynthesis (a form of photosynthesis in which the stomata only open to take in carbon at night when the air is relatively cool, thereby minimizing water loss through evaporation and allowing the carbon to be put to use in photosynthesis when the sun rises the next day.) The inside of the stem of a California Barrel Cactus is spongy and allows water to be stored as a gel during times of relatively high rainfall to sustain the cactus during times of drought, and as the roots of this species do not go deep into the soil and can re-grow easily California Barrel Cacti can survive being completely uprooted by flash floods, and may even take advantage of floods by allowing them to carry them to areas where the flood water settles, where they will then develop new roots and take in the plentiful water. Like most cacti California Barrel Cacti are hermaphroditic (meaning that every individual can produce both pollen and seeds), and during the early summer they develop “crowns” of yellow flowers which, following pollination by small insects such as bees, develop into small, egg-shaped yellow fruits which are eaten by birds and carried away to allow the seeds within them to develop into mature cacti without competing with their parent.

I’ll be doing a module on plant biology later this year, so I’m brushing up on plants. This is a particularly cool species!

Prismatic Batteries vs. Cylindrical Batteries: Unpacking the Differences

Various shapes and sizes of lithium-ion batteries cater to different applications, and two contenders have been in the spotlight: prismatic and cylindrical batteries.

Let's explore these powerhouses and understand why the Prismatic Batteries might be ready to steal the show.

Prismatic Batteries: Power in a Box

Prismatic batteries come in rigid shells with a rectangular shape, allowing them to be stacked efficiently in battery modules. There are two types of prismatic batteries: stacked and flat. Stacked prismatic batteries deliver a powerful energy burst, perfect for high-performance applications. On the other hand, flat prismatic batteries focus on energy density, providing long-lasting durability. These batteries are commonly used in energy storage systems and electric vehicles due to their larger size and capacity, making them less suitable for smaller devices such as mobile phones.

Cylindrical Batteries: Compact and Versatile

Cylindrical batteries, as their name implies, come in cylindrical casings. Their compact and rounded design enables easy fitting into devices of different sizes. One of their key benefits is their ability to prevent expansion, a common problem in batteries that leads to gas buildup inside the casing. These versatile power sources initially gained recognition in laptops and have since become widely used in electric vehicles, electric bicycles, medical equipment, and space exploration. Their ability to withstand atmospheric pressure variations makes them essential for missions like those involving Mars rovers.

Key Differences between Prismatic and Cylindrical Batteries

Size Matters: Prismatic batteries outsize their cylindrical counterparts, holding significantly more energy. To put it into perspective, a single prismatic battery can match the energy of 20 to 100 cylindrical batteries. Cylindrical batteries, being smaller in size, are suitable for applications requiring lower power and are used in a wider range of devices.

Fewer Connections: Prismatic batteries require fewer connections due to their larger size. This means there are fewer chances for manufacturing defects, giving them a significant advantage over cylindrical batteries.

Energy vs. Power: Although cylindrical batteries store less energy, they deliver a more powerful performance. This is because they have more connections per ampere hour (Ah). As a result, cylindrical batteries excel in high-performance applications, while prismatic batteries are great for optimizing energy efficiency.

The Prismatic Battery Revolution

The electric vehicle industry, known for its rapid evolution, poses an intriguing question: will prismatic batteries eventually surpass cylindrical ones? Currently, cylindrical batteries dominate the sector, but several factors suggest that prismatic batteries might overthrow them.

Prismatic batteries offer cost-saving opportunities by streamlining manufacturing processes. Their larger size allows for the production of bigger batteries, reducing the number of electrical connections that need welding. Furthermore, prismatic batteries are a perfect match for lithium iron phosphate (LFP) chemistry, known for its affordability and accessibility.

Unlike other chemistries, LFP batteries use easily available materials, eliminating the need for expensive rare materials like nickel and cobalt.

The rise of LFP prismatic cells is already evident, with Asian electric vehicle manufacturers adopting prismatic LFP batteries.

However, LFP chemistry has its limitations, including lower energy storage capacity, making it unsuitable for high-performance applications. Additionally, battery management systems may face challenges in accurately predicting charge levels.

Prismatic Batteries in Energy Storage Systems

The demand for battery packs goes beyond electric vehicles, with energy storage systems (ESS) playing a crucial role. Prismatic batteries are already preferred in ESS applications due to their longer cycle life, reduced risks, and lower costs compared to cylindrical batteries.

Tesla's 4680 cylindrical cells have gained considerable attention for their compact design, high energy density, and cost efficiency. While prismatic batteries have not yet replaced them, Tesla's future decisions could tip the scales.

Will Tesla transition to LFP chemistry and embrace prismatic batteries? The answer could have a significant impact on the battery landscape, especially with the rising global raw material costs.

The stage is set for an intriguing battle between prismatic and cylindrical batteries, and only time will reveal the winner in this electrifying competition.

Elantra N et le rassemblement de Terrebonne

Le 14 septembre 2024

Les constructeurs américains ne sont plus dans le coup…surtout lorsqu’il s’agit de petites berlines agréables à conduire. Ils sont devenus des spécialistes de VUS et de pick-up de tout gabarit sauf pour quelques sportives ultra-puissantes à prix exorbitants. Ils semblent avoir laissé le créneau des berlines et des coupés compactes et même intermédiaires aux constructeurs d’autres pays. C’est ainsi que les constructeurs sud-coréens ont hérité d’un espace de choix dans le domaine des petites berlines que l’on croyait attribué aux européens et aux japonais. Comment s’en sont-ils sortis? Mieux que l’on pense. Le meilleur exemple nous vient de Hyundai, cet important producteur de voitures aux dimensions raisonnables capable de concurrencer surtout les Japonais! Et l’Elantra est fort possiblement son meilleur argument sur le marché!

L’Elantra? Cette belle berline qui réussit à se distinguer dans le créneau des « petites » intermédiaires? Pourquoi pas? Néanmoins, c’est bien beau de réussir dans un créneau populaire mais… « ennuyant » ? C’est là que la concurrence a compris qu’il fallait créer des autos de cette catégorie avec un peu plus de « plaisir de conduite »! Cette concurrence, c’est Honda et surtout Volkswagen qui auront su concocter des versions plus « amusantes » de leurs berlines … « ennuyantes » comme les Honda Civic Si, Toyota Corolla GR, les VW GTI et autres! Il n’en fallait pas plus pour que les décideurs de Séoul en arrivent à des Elantra plus « sportives ». Et de là sont nées les Elantra N.

La berline Hyundai Elantra N affiche un avant très menaçant! (Photo Éric descarries)

Elantra N! Le nom ne nous dit pas grand-chose. Mais lorsqu’on en examine les caractéristiques, on écarquille les yeux! Hyundai Canada m’a récemment confié une de ces berlines Elantra N et l’effet fut plus étonnant que prévu!

Qu’est-ce qu’une Hyundai Elantra N? Au départ, je le répète, c’est une berline dite intermédiaire (moi, je la trouve plutôt compacte…) avec une présentation plus sportive incluant une calandre repeinte en noir, un pare-chocs avant abaissé, un déflecteur arrière et des diffuseurs intégrés. Ajoutez à cela des roues plus excitantes, des pneus Michelin larges et une peinture avec des lignes évidentes et le tour est joué. On obtient alors une berline au look sportif.

Même de l’arrière, on ne peut ignorer la version N de la récente Elantra. (Photo Éric Descarries)

Cependant, l’habit ne fait pas nécessairement le moine. L’Élantra N (à ne pas confondre avec l’Elantra N Line!) cache sous son capot une mécanique plus élaborée malgré le fait que la voiture demeure une traction avant seulement. Son moteur est un « modeste » quatre cylindres turbocompressé à double arbre à cames en tête de 2,0 litres qui a déjà équipé le sportif coupé Veloster. Il fait alors 276 chevaux (286 avec la boîte automatique). La voiture qui m’a été confiée était équipée d’une boîte manuelle à six rapports ce qui, à mes yeux, fait encore plus sportif! Ses roues de 19 pouces en alliage léger étaient chaussées d’impressionnants pneus Michelin Pilot Sport 4S 245/35 ZR. Le freinage se fait par des disques aux quatre roues dont ceux d’avant font 14 pouces et ceux d’arrière font 12 pouces. Quant au poids, l’auto pèse quelque 3200 livres.

Le tableau de bord de l’Elantra N est plutôt moderne. (Photo Éric Descarries)

L’intérieur de l’Elantra N est pareil à celui des autres Elantra de tourisme. Sauf que sa finition y est plus « sportive »! En fait, mais elle est surtout plus plastique! Le tableau de bord (pareil à l’Elantra de base) offre une ligne classique mais son instrumentation peut être modulable avec des cadrans « vidéo » plus réguliers ou plus sportifs selon la commande électronique du comportement de la berline. Celle-ci se fait par l’ordinateur central qui permet au conducteur de « jouer » avec ces modes de conduite. Si la version régulière demeure plutôt discrète, le choix de la « Sport » raffermit la suspension et l’effort au volant et rend l’échappement un peu plus bruyant.

Les places arrière sont très élégantes mais surtout spacieuses pour une berline de ce calibre! (Photo Éric Descarries)

Outre cela, Hyundai a choisi d’équiper cette N avec des sièges avant plus fermes et plus moulants qui devraient être utiles si l’on fait régulièrement des exercices de conduite (« lapping ») mais qui peuvent s’avérer moins confortables sur de longues distances. Ces sièges procurent un excellent support latéral mais, pour de longs déplacements, je suggérerais des coussins supplémentaires de Canadian Tire!

Le coffre est suffisant mais on ne peut pas l’agrandir car les barres de renforcement (rouges) empêchent le dossier des sièges d’arrière de se replier. (Photo Éric Descarries)

Les places arrière sont plus conventionnelles mais aussi plus accueillantes…et confortables à la longue. La malle est relativement utile mais sachez que le dossier des sièges d’arrière ne s’abaisse pas. Hyundai y a choisi le croisement des « volumes » pour y ajouter des barres de renforcement devant raffermir la souplesse de la coque pour aider la voiture à être plus ferme, moins souple et à moins « tordre » en compétition. Car, c’est cela une Elantra N, une auto de course déguisée pour la rue!

Sur la route

L’Élantra N est une superbe petite berline pour des déplacements urbains. Mais on sent qu’elle voudrait être « brassée ». Sa conduite est simple et agréable même si c’est une auto à boîte manuelle, ce qui ne me dérange pas malgré mon âge qui avance de plus en plus. C’est quand même drôle de voir un « p’tit vieux » qui aime plutôt le passage mécanique des rapports que la paresse de laisser la boîte automatique tout faire (oui, je possède et conduis des Lincoln dont ma « sportive » MKZ mais j’ai aussi une Jeep à boîte mécanique et ma Cobra à cinq vitesses, ne l’oubliez pas!).

Toutefois, il faut savoir choisir ses routes de campagne pour savoir profiter du comportement sportif de cette auto. Les larges mais très « gommants » pneus Michelin apportent beaucoup à ce comportement mais en vérité, on aimerait pouvoir profiter d’une petite piste comme le « défunt » circuit de l’Autodrome Saint-Eustache pour vraiment exploiter  les capacités de l’Elantra N!

On ne peut malheureusement pas voir le moteur de l’Elantra N caché sous le couvercle de plastique mais on peut juger de la qualité du travail de finition. (Photo Éric Descarries)

Lorsqu’on place la commande N en action (au volant), la voiture change un peu. Ce n’est pas une transformation dramatique mais on se sent plus au volant d’une sportive avec une suspension plus ferme, une direction plus responsive et un échappement légèrement plus libre. Mais le plaisir ne peut durer qu’un petit moment vu les restrictions du code de la route (pourquoi n’avons-nous plus de ces courtes pistes comme Saint- Eustache pour vivre ces sensations? Qui a permis la construction de ces maisons si près d’une piste de course qui, avouons-le, n’était pas aussi bruyante à tous moments?).

Je suis un voyageur. Je viens de revenir encore une fois d’Ogunquit dans le Maine (cette fois-ci avec ma MKZ). Je préfère les grand-routière aux sportives furtives. Malgré tout, je me suis rendu de Laval à Gatineau avec ma compagne pour assister à un pagean aérien (je suis mordu d’aviation et des spectacles comme celui des Thunderbirds américains (F-16), des Red Arrows britanniques ( BAE Hawk T.1) et des Snowbirds canadiens (Canadair CT-114 Tutors). La route semble facile, de Laval à Gatineau par la 15 nord et la 50 ouest mais suffisante pour évaluer les aptitudes routières de l’Elantra N.

Si j’ai su m’amuser un peu avec le comportement routier de la N sur d’autres routes locales sinueuses, cette petite berline de Hyundai est moins indiquée pour de longs voyages. Les sièges si fermes avec une excellente rétention dans les courbes deviennent trop durs pour de longs déplacements. On peut s’y faire avec la suspension plus dure en autant que la route soit bien pavée (ce qui n’est pas nécessairement le cas au Qu��bec!). Et les divers revêtements du pavé autoroutier transmettront beaucoup de bruit dans l’habitacle (ce ne sont pas les pneus…c’est l’isolation des puits d’ailes!).

Ces pneus Michelin de l’Elantra N font grandement partie de l’excellente tenue de route de la berline. (Photo Éric Descarries)

En passant, les performances de l’auto sont remarquables avec une possibilité de passer de 0 à 100 km/h en moins de six secondes (si vous êtes rapide au levier de vitesses) et des reprises facilitant les dépassements. La direction est précise et le freinage puissant (avec la N). Toutefois, il faut se souvenir que l’Elantra N est une sportive unique conçue pour rivaliser avec d’autres voitures du même genre. Il faut savoir aimer conduire une voiture nerveuse et sauvage en même temps. Incidemment, j’ai bien apprécié la rigidité de sa caisse et la solidité de la construction. Conclusion, le constructeur sud-coréen Hyundai est capable de se mesurer à sa concurrence, surtout européenne!

Question consommation, j’ai obtenu une moyenne de quelque 9,0 l./100 km ce qui ressemble à ce que le constructeur publie (11,0 en ville, 8,1 sur toute pour une moyenne prévue de 9,7).  Le prix annoncé (2024) est de 41 896 $ (incluant le transport et la préparation) alors que le constructeur lui accorde une garantie de 5 ans ou 100 000 km, ce qui est plutôt intéressant. Parmi ses concurrentes, on retrouvera les Honda Civic R ou Si, Toyota Corolla GR, VW Golf GTi et quelques autres voitures du genre.

Encore une fois, ne pas confondre l’Elantra N avec la version N Line qui est moins élaborée. La version N est nettement plus sportive. Moins confortable mais plus excitante à conduire. Sachez aussi en passant que ces Elantra sont de féroces compétiteurs en course automobile dans leur catégorie. Intéressant, n’est-ce pas?

Le rassemblement des anciennes à Terrebonne

À la dernière minute, quelques heures avant de publier ce blogue, j’ai su que le populaire rassemblement des voitures anciennes à l’Île-des-Moulins de Terrebonne était de retour après quatre ans d’absence. Et, à ma grande surprise, il y avait plus de voitures que je ne m’étais imaginé. Bien entendu, j’aurais voulu y voir plus de « vraies » anciennes des années vingt ou trente mais, en revanche, il y avait plusieurs voitures d’intérêt!

Malgré l’annonce de dernière minute, les amateurs de voitures anciennes ont été bien servis à Terrebonne. (Photo Éric Descarries)

Une des voitures les plus spectaculaires était certes le cabriolet Chrysler New Yorker 1956 du vétéran Robert Aubin (frère du regretté Claude Aubin de l’Autodrome Saint-Eustache). (Photo Éric Descarries)

Fort possiblement la plus vieille auto sur le site, cette Buick 1908 ne manquait pas d’attirer l’attention! (Photo Éric Descarries)

Autre véhicule spectaculaire et surtout très rare (704 unités de produites à la main en 1957 et 1958), cette Cadillac Eldorado Brougham 1957 affichait une plaque du Québec! (Photo Éric Descarries)

Cette Mercury Park Lane de 1957 était équipée de phares doubles pour la première fois et surtout de beaucoup de chrome autour de ses lignes « futuristes » ! (Photo Éric Descarries)

Coup de cœur! Cette Austin 1949 de Laval m’a séduit! (Photo Éric Descarries)

Un certain nombre de petites Fiat 500 de 1957 à 1975 s’était rassemblé près de la rivière! (Photo Éric Descarries)

How ED Medications Work: The Science Behind the Solutions

Erectile dysfunction (ED) is a condition that affects millions of men worldwide. It’s a topic that, despite its prevalence, remains shrouded in a mix of embarrassment and misunderstanding. Fortunately, advancements in medical science have led to the development of effective treatments that can help restore sexual function and improve quality of life. Understanding how these medications work can provide insight into their efficacy and reassure those seeking relief. In this blog, we’ll delve into the science behind ED medications, exploring the mechanisms that make them effective.

Understanding Erectile Dysfunction

Before we dive into how ED medications work, it’s essential to understand what happens in the body during an erection. An erection is a complex physiological process that involves the interaction of the nervous, vascular, and endocrine systems. It begins with sexual arousal, which can be triggered by physical or psychological stimuli. This arousal causes the brain to send signals through the nervous system to the blood vessels in the penis.

In response to these signals, the blood vessels dilate, allowing increased blood flow into the penile tissues. This blood fills the corpora cavernosa, the two cylindrical structures in the penis, causing it to enlarge and become rigid. At the same time, the veins that usually drain blood away from the penis are compressed, trapping the blood and maintaining the erection.

The Role of ED Medications

ED medications primarily target the vascular component of this process. They work by enhancing the natural mechanisms that promote blood flow into the penis and sustain an erection. Let’s explore the two main classes of ED medications and how they function.

1. Phosphodiesterase Type 5 (PDE5) Inhibitors

The most common and well-known ED medications are PDE5 inhibitors. These include sildenafil (Viagra), tadalafil (Cialis), vardenafil (Levitra), and avanafil (Stendra). The primary mechanism of action for PDE5 inhibitors involves the modulation of a specific enzyme in the body.

In the penis, sexual stimulation leads to the release of nitric oxide (NO), a molecule that helps relax smooth muscle cells in the blood vessels. This relaxation allows the blood vessels to dilate, increasing blood flow and resulting in an erection. Nitric oxide achieves this effect by increasing the levels of cyclic guanosine monophosphate (cGMP), a signaling molecule that promotes smooth muscle relaxation.

However, cGMP is broken down by an enzyme called phosphodiesterase type 5 (PDE5). PDE5 inhibitors work by blocking this enzyme, thereby preventing the breakdown of cGMP. As a result, cGMP levels remain elevated for longer periods, leading to prolonged relaxation of the smooth muscles and sustained blood flow into the penis.

This mechanism explains why PDE5 inhibitors are effective in treating ED. By ensuring that cGMP levels remain high, these medications enhance the body’s natural ability to achieve and maintain an erection.

2. Alprostadil

Another medication used to treat ED is alprostadil, which works differently from PDE5 inhibitors. Alprostadil is a synthetic form of prostaglandin E1, a naturally occurring substance in the body that helps dilate blood vessels and increase blood flow.

Alprostadil can be administered either as an injection directly into the penis or as a urethral suppository. When injected, it causes the blood vessels in the penis to dilate, leading to increased blood flow and an erection. When used as a suppository, it is absorbed through the urethral lining and produces similar effects by relaxing the smooth muscles and dilating the blood vessels.

This method of treatment can be particularly useful for men who do not respond well to PDE5 inhibitors or have contraindications to their use. Alprostadil’s ability to directly influence blood vessel dilation provides an alternative pathway to achieving an erection.

The Science Behind Effectiveness

The effectiveness of ED medications depends on several factors, including the underlying cause of the condition, the specific medication used, and individual patient response. PDE5 inhibitors, for instance, are highly effective for many men with ED related to vascular issues, but they may be less effective for those with severe nerve damage or psychological causes of ED.

The onset of action and duration of effect can also vary between different medications. For example, sildenafil typically works within 30 to 60 minutes and lasts for about 4 to 6 hours, while tadalafil can take up to 2 hours to take effect but lasts up to 36 hours, earning it the nickname "the weekend pill."

Individual response to these medications can vary widely. Factors such as age, overall health, and the presence of other medical conditions can influence how well these treatments work. It’s also important to note that ED medications are not a cure-all; they can help manage symptoms but do not address the underlying causes of ED, which may require additional treatment or lifestyle changes.

Potential Side Effects and Considerations

While ED medications are generally safe and effective, they can have side effects. Common side effects of PDE5 inhibitors include headaches, flushing, nasal congestion, and digestive issues. In rare cases, they can cause more severe reactions, such as sudden vision loss or priapism (a prolonged and painful erection).

Alprostadil, on the other hand, can cause pain at the injection site or irritation of the urethra. It’s crucial for patients to discuss potential side effects and interactions with their healthcare provider to ensure the chosen medication is appropriate for their condition and health status.

Conclusion

ED medications represent a significant advancement in the treatment of erectile dysfunction, offering hope and improved quality of life for many men. By understanding the science behind these treatments—whether through PDE5 inhibition or direct vascular dilation—patients can make informed decisions about their care. It’s always essential to work closely with a healthcare provider to choose the most appropriate treatment and address any underlying health issues contributing to ED. With the right approach, managing erectile dysfunction can become a manageable part of maintaining overall health and well-being.

What is the difference between Mono Photovoltaic Module and Poly Photovoltaic Module

If you're considering solar power for your home or business, you've probably come across the terms "mono" and "poly" photovoltaic (PV) modules. But what's the difference between the two? In short, mono PV modules are made of single-crystalline silicon cells, while poly PV modules are made of multi-crystalline silicon cells. Mono PV modules tend to be more efficient, but they're also more expensive. Poly PV modules are less efficient but more affordable. So, which one is right for you? It depends on your needs and budget. Keep reading to learn more about mono and poly PV modules, and how to choose the right one for your solar project.

Mono Photovoltaic Module

Mono-crystalline silicon photovoltaic (PV) cells are made of a single crystal, or monocrystal, of silicon. They are distinguished from polycrystalline silicon PV cells, which are made of many small crystals, or polycrystals, of silicon.

Mono-crystalline PV cells are cut from a single large crystal of silicon that has been grown in a laboratory. The ingot, or cylindrical chunk, of single crystal silicon from which mono-crystalline PV cells are cut is typically about six inches (15 cm) in diameter and four to six feet (1.2 to 1.8 m) long.

Polycrystalline PV cells are made of many small crystals of silicon. They are cast into an ingot and then cut into wafers like mono-crystalline PV cells. However, the manufacturing process used to make polycrystalline PV cells is less costly than that used for making mono-crystalline PV cells.

Mono-crystalline PV cells have a higher efficiency than polycrystal PV cells because they suffer less from what is called the “recombination loss” of electrons. When light strikes a solar cell, it can knock electrons loose from their atoms. These free electrons can flow through the material to conductive metal contacts

Poly Photovoltaic Module

In general, a photovoltaic module is made up of two layers of semiconductor material, usually silicon. These layers have been treated so that one will be positively charged and the other negatively charged. When light shines on the module, it causes electrons to flow between the two layers and generates electricity.

A mono photovoltaic module has only one layer of silicon, while a poly photovoltaic module has multiple layers of silicon. The advantage of a poly module is that it can capture more sunlight than a mono module, since each layer of silicon can absorb photons from a different part of the solar spectrum. This means that a poly module can generate more electricity than a mono module with the same surface area.

Difference between Mono and Poly Photovoltaic Module

Mono-crystalline photovoltaic (PV) modules are made out of a single crystal silicon ingot, while poly-crystalline PV modules are made out of multiple smaller silicon crystals. The main difference between the two types of PV modules is in their efficiency. Mono-crystalline PV modules typically have a higher efficiency than poly-crystalline PV modules, due to the higher quality of the single silicon crystal. Mono-crystalline PV modules also tend to be more expensive than poly-crystalline PV modules.

Mono crystalline silicon cells are made from a single, large crystal of silicon, while poly crystalline silicon cells are made from multiple small crystals of silicon. Mono photovoltaic modules are more efficient than poly photovoltaic modules, but they are also more expensive to manufacture.

Demystifying Power Battery Components: Cells, Modules, and Packs

The electric vehicle and energy storage markets have been on a relentless rise, attracting an influx of newcomers and partners to the battery industry. For those transitioning from academia to industry or anyone new to this dynamic field, it's essential to grasp the fundamental components of power batteries. Today, we'll explore the three most crucial elements: cells, battery modules, and battery packs.

1. Cells: The Building Blocks

Cells serve as the fundamental building blocks of power batteries, typically lithium-ion batteries. These cells offer a working voltage ranging between 3V and 5V, which, although respectable, is insufficient for providing the high voltage and capacity needed to propel electric vehicles. As a result, cells are connected in series to form a battery module. Series connections elevate voltage, while parallel connections increase capacity.

There are three common types of cells:

Cylindrical Cells: These are compact, tubular batteries often seen in consumer electronics.

Prismatic Cells: These come in rectangular shapes and are typically used in portable electronics and energy storage systems.

Pouch Cells: These cells are made of flexible aluminum-plastic film and are versatile in shape and design, making them suitable for a variety of applications.

It's essential to note that the choice between square and soft-packed cells is largely dependent on specific requirements and material properties.

2. Battery Modules: Structured Assemblies

Given that a battery pack comprises thousands of individual cells, managing them all effectively requires a structural organization. This is where battery modules come into play. Cells are initially connected and housed within frames to form these modules. Various battery assembly equipment are used to form packs from cells and provide an additional layer of protection, shielding cells from external factors such as heat and vibration.

An example of a battery module can be found in Tesla's electric vehicles. The Tesla battery module consists of multiple cells, offering robust energy storage and a safeguarded structure.

3. Battery Packs: The Powerhouses

Multiple battery modules are connected in series, and a battery management system (BMS) is incorporated along with cooling equipment for temperature and voltage regulation. This integration gives rise to a formidable battery pack. Essentially, a battery pack is the form in which multiple cells are installed in an electric vehicle, providing the necessary energy to power the vehicle. An instance of this configuration is the BMW i3's battery, which contains a total of 96 cells. In this arrangement, 12 cells form a module, and eight modules combine to create the battery pack.

The table below summarizes the key distinctions between cells, battery modules, and battery packs:

4. Battery Pack Assembly: A Comprehensive Process

In general, assembling a battery pack is a systematic process that involves moving from cells to modules and eventually to the battery pack. Each step plays a crucial role in ensuring the efficient operation of the battery system. This system is called a Lithium-ion battery pack assembly line. after understanding cells, modules, and packs, the assembly line completes the list of fundamental components to know about lithium-ion batteries. 

In conclusion, understanding these fundamental components—cells, battery modules, and battery packs—lays the groundwork for navigating the intricate world of power batteries. As the electric vehicle and energy storage sectors continue to advance, this knowledge becomes increasingly essential for both newcomers and industry experts alike.

Deux Mustang et la Fête chez JacHOBBY

Le 15 août 2024

Comme promis la semaine dernière, le sujet du blogue de cette semaine portera sur la nouvelle Mustang 2024 mais en deux versions différentes, soit un cabriolet EcoBoost et un coupé GT. Vous aurez compris que l’EcoBoost est le modèle mu par le quatre cylindres biturbo de 2,3 litres alors que la GT est celle tant recherchée avec le V8 de 480 chevaux…rien de moins!

J’aurais dû disposer de la GT plus tôt dans la saison mais il y a eu des changements dans sa disponibilité. Par conséquent, j’ai eu droit d’abord au modèle cabriolet, une superbe voiture toute rouge qui ne passait pas inaperçue. En effet, nombreuses sont les personnes qui m’ont passé de belles remarques sur son look. Ajoutez à cela l’option Performance Package qui incluait des roues spéciales, des pneus Pirelli très larges et des freins Brembo dont les étriers étaient identifiés du nom de la compagnie.

Lors des premiers jours d’essai de cette magnifique voiture, j’ai pu lire un reportage de mon ami Christian Gagnon qui venait de faire un petit « Road trip » du côté d’Ogunquit dans le Maine. Ironiquement, moi aussi je me préparais à un tel petit voyage mais cette fois, au volant de la Mustang rouge. Ce n’est pas la première fois que Ford me prête un cabriolet Mustang pour un tel déplacement. Mais cette fois, c’était avec la version à moteur EcoBoost, soit ce puissant quatre cylindres biturbo à double arbre à cames en tête qui fait 315 chevaux et 350 li-pi de couple! Je sais, je sais! Vous allez dire : « Une Mustang à quatre cylindres, ce n’est pas une Mustang ! ». Erreur! Il ne s’agit pas ici des Mustang des années quatre-vingt dix avec un petit quatre anémique. Si vous vous souvenez bien, une Mustang GT de 1967-68 avec un V8 de 390 pouces cubes (6,4 litres) ne faisait que 300 chevaux! Et alors que cette dernière pouvait être commandée avec une boîte automatique à trois rapports ou manuelle à quatre vitesses, la nouvelle mouture avec l’EcoBoost sera livrée qu’avec une boîte automatique à 10 rapports! Mes quelques essais d’accélération m’ont prouvé que cette Mustang pouvait passer de 0 à 100 km/h en moins de six secondes! Sachez que sa vitesse maximale de cette nouvelle Mustang dépasse les 200 km/h! Ces chiffres sont nettement supérieurs à ceux d’une Mustang GT de 1967-68! Et ajoutez à cela tellement plus de sécurité possible !

La direction avec assistance électrique est conçue pour des réactions qui peuvent s’avérer inattendues! Faut dire que les pneus Pirelli PZ4 (PZero) 255/40R 19 y sont pour beaucoup. Mais avec un peu de pratique, on apprend à maîtriser la bête. Le freinage du groupe de Performance est de fabrication italienne Brembo et ils peuvent être très agressifs si on les sollicite vraiment! Enfin, la suspension arrière désormais indépendante contribue vraiment à faire de cette auto une véritable voiture sportive avec une tenue de route exceptionnelle! Il faut spécifier que les ingénieurs de Ford ont grandement revu le châssis de la Mustang pour 2024. En passant, Ford avait également équipé mon petit cabriolet du système d’échappement modulable électronique qui permet un certain son « libre ». À certains niveaux, ce son peut être désagréable. Mais à plein gaz, il se rapproche de celui des voitures sport haut de gamme. Néanmoins, je trouve qu’à près de 1500 $, c’est payer cher pour cet effet pas toujours réussi!

Donc, direction Ogunquit! Le temps étant moins agréable, nous sommes descendus, ma compagne et moi, par l’autoroute américaine 89 jusqu’à la 93 sud à Concord, New Hampshire pour bifurquer sur la 101 qui devait nous mener à la 95 nord. Toutefois, à la hauteur de celle-ci, j’ai plutôt décidé de continuer vers la route 1 qui longe le littoral de la mer. Nous nous sommes alors retrouvés dans la région de Hampton. Je vous recommande une tournée dans cette région où les maisons du bord de mer sont d’une grande beauté (et d’une grande richesse!). Puis, le soleil est sorti, juste en temps pour baisser la capote et finir le voyage vers Ogunquit, toujours sur la route 1.

L’intérieur de la Mustang 2024 (identifiée du numéro de code S650) a été complètement refait incluant un nouveau tableau de bord coiffé d’un énorme écran horizontal qui permet de reproduire quatre types d’instruments incluant celui imitant les cadrans analogiques des anciennes versions. Malheureusement, le design de ce tableau de bord n’est pas aussi élégant que celui de presque toutes les versions d’antan. Il n’y a donc plus de ces deux « niches » qui caractérisaient si bien les Mustang. Mais, ce que j’ai y trouvé de plus agaçant, c’est que l’écran en lui-même est très difficile à lire en plein soleil lorsque la capote est abaissée. Outre cela, mon cabriolet Mustang d’essai avait cette option de performance qui, après un peu de recherche dans l’ordinateur, me permettrait de conduire en mode « drift »! Avec cette option, on obtient un frein de stationnement avec un bras semblable à celui d’un système mécanique. Toutefois, il s’agit d’une adaptation électronique qui exige qu’on le pousse vers le bas pour le dégager. Faire de la « drift » avec une Mustang équipée de pneus P Zero ? Pas pour moi, merci.

Malgré la petitesse de l’habitacle, les places arrière peuvent être utiles pour de courtes distances. (Photo Éric Descarries)

Croyez-le ou non, il y a un moteur à quatre cylindres là-dessous! (Photo Éric Descarries)

Si le coffre vous semble petit, sachez que je réussis à y « paqueter » nos valises et des accessoires de plage. (Photo Éric Descarries)

Quant à la malle, sachez qu’elle peut contenir plus de bagages que vous ne le pensez. Malheureusement, l’option de la sonorisation supérieure inclut un haut-parleur « sub-woofer » dans le coffre qui prend un peu de place!

Sur la route

Donc, sur la route, ce cabriolet Mustang est tellement agréable à conduire. L’habitacle est relativement silencieux (sauf sur du pavé rugueux) et la suspension respectable malgré l’option de performance. Encore une fois, la direction est vraiment stable mais attention aux corrections brusques, même les plus délicates. Cette direction réagit très rapidement.

Les pneus Pirelli contribuent grandement à la superbe tenue de route de cette Mustang. (Photo Éric Descarries)

Si le besoin de dépasser se présente, vous pouvez compter sur la puissance étonnante du quatre cylindres. La visibilité est très bonne malgré la capote. Évidemment, si vous l’abaissez, elle est encore meilleure. En passant, je suis revenu d’Ogunquit avec la capote abaissée, même dans les montagnes. Avec les glaces relevées, le voyage fut des plus agréables.

Bien entendu, la Mustang à propulsion n’est pas le véhicule idéal pour les routes enneigées quoique certains essais que j’ai faits avec des pneus d’hiver appropriés se sont avérés concluants sur des routes enneigées ou glacées. Tout dépend du jugement du conducteur. Pour les plus vieux ayant connu la période où nous n’avions que des autos à propulsion, ce n’est qu’une question de se rappeler des plus vieilles techniques au volant. Ma Mustang d’essai avait un pont arrière Torsen qui peut aider durant la saison froide.

Question consommation, mon voyage incluant de petites excursions annexes m’a donné une lecture moyenne de 9,7 l./100 km. Il est mieux d’utiliser de l’essence super pour mieux exploiter le moteur EcoBoost. Mais pour de telles excursions, l’essence régulière devrait suffire.

Cette toute dernière génération de Mustang en version cabriolet peut valoir 48 500 $ mais celle qui me fut confiée par Ford ira chercher dans les 63 650 $ à cause des nombreuses et coûteuses options incluant celle de performance (6500 $), le système d’échappement modulable (1495 $) et la suspension avec ajustements électroniques (2500 $). Ajoutez-y les 2095 $ de transport et préparation et vous vous retrouverez avec une facture finale de 65 460 $.

Et la GT, elle?

De retour du Maine, j’ai échangé le cabrio pour un coupé mais en version GT mû par un puissant V8 de 5,0 litres qui ne développait pas moins de 486 chevaux! Dans ce cas, ce puissant bolide était équipé d’une boîte manuelle à six rapports. Toutefois, ce superbe bolide tout jaune n’avait pas autant d’options sauf pour celle des échappements modulables de 1495 $. Une fois en fonction libre (ce qui peut venir avec la fonction Race disponible par l’intermédiaire de l’ordinateur), ils émettent le son tant recherché d’un V8 débridé. Ce son est nettement plus agréable que celui du quatre cylindres mais il viendra avec le coût d’opération du V8! Il est possible de l’atténuer pour le démarrage en milieu urbain (pour le pas « écœurer » les voisins mais pour ce faire, il faut encore une fois passer par l’ordinateur de bord.

L’intérieur du coupé GT est tout aussi accueillant que celui du cabriolet mais il diffère de ce dernier par le fait que la division entre les sièges arrière et le coffre obligatoire sur le cabrio est remplacé par des les dossiers repliables des sièges arrière ce qui augmentera considérablement la capacité de chargement des bagages pour deux occupants! Incidemment, ce coupé n’avait pas l’option des modes de conduite de Performance alors on n’y voit pas le levier des freins d’urgence. À la place, on y voit le commutateur du frein de stationnement électrique.

Sur la route

Bien entendu, conduire une GT est une expérience totalement différente que celle au volant de l’ÉcoBoost. Dans le cas de ce coupé, je m’en suis tenu à des déplacements en situation urbaines sauf pour quelques petites excursions sur autoroute.

Les accélérations de la version GT sont, on s’en doute, beaucoup plus excitantes que celles de l’ÉcoBoost alors que passer de 0 à 100 km/h en moins de 5 secondes. Je vous épargne la vitesse maximale qui devrait dépasser les 240 km/h! Sauf que, dans le cas de ma GT d’essai, celle-ci était équipée de pneus Continental ProContact alors que Ford m’avait habitué à des Pirelli P Zero. Ce devrait être un pneu tout aussi performant mais…Voilà, peut-être, la cause d’un certain vague dans la direction de cette auto. Autrement, il est difficile de trouver des défauts à cette voiture, du moins du côté des performances. En ce qui a trait à la consommation, j’ai obtenu une moyenne de 14,7 l./100 km (l’ordinateur de bord indiquait 15,0) mais, encore une fois, en situation presque uniquement urbaine. Cependant, sur grand route, le même indicateur marquait autour des 10,5 l./100 km.

Le très performant Ford V8 de 5,0 litres fait quelque 486 chevaux…sans turbo comme chez la concurrence…(Photo Éric Descarries)

Ma GT d’essai était chaussée de pneus Continental ProContact..(Photo Éric Descarries)

Ford a révisé sa Mustang pour 2024 mais, heureusement, il ne lui a rien enlevé au point de vue agrément de conduite et surtout d’excitation ! Dans le cas de la voiture que vous voyez ici, il s’agit d’un véhicule presque de base dont le prix d’entrée est de 54 400 $. Ma GT d’essai avait quelque 6595 $ d’options incluant les 3000 $ pour le Groupe 401A (incluant l’assistance de conduite Co-Pilot 360 et la navigation). Ajoutez-y 1760 $ pour l’ensemble de décoration Nite Pony et les 1495 $ pour la gestion des sons d’échappement. La facture incluait 250$ pour les carpettes de caoutchouc mais je déconseille cet achat car les carpettes ont des rainures horizontales très profondes qui accrochaient les talons des souliers! Enfin, il faut ajouter la taxe d’accise de 100 $ pour le climatiseur et les 2095 $ de transport et préparation et on en arrive à un prix total de 63 090 $ !

Si vous pensez que je me suis « payé la traite » avec des Mustang, regardez-y à deux fois. Je suis prêt à parier que Ford soit à créer une deuxième marque avec Mustang, une marque qui remplacera l’ancien nom de Mercury. Vous avez déjà connu la version électrique des Mustang (Mach E), attendez-vous à plus. En effet, lors de la dernière rencontre des concessionnaires Ford aux États-Unis, le constructeur américain leur a montré des prototypes ou projets de Mustang à quatre portes et de Mustang hors-route (plus poussées que la version Rally de la Mach E). Il y aurait aussi une autre voiture plus petite dont on ne sait rien jusqu’ici. De plus, Ford serait à préparer un petit fourgon de livraison basé sur la camionnette Maverick (et ce, après avoir abandonné le Transit Connect). Ce n'est pas fini!

La Fête chez JacHOBBY !

Dimanche dernier, mon ami Jacques Legault tenait à son commerce JacHOBBY de Laval une petite réunion de voitures modifiées sous l’enseigne des Bagnoles du Nord. En même temps, Jacques organisait pour la première fois une exposition de maquettes miniatures et tout cela malgré une météo menaçante (et ce, quelques jours après la pluie catastrophe du vendredi du 9 août).

C’était la deuxième édition de cette fête chez JacHOBBY et on lui souhaite du plus beau temps pour la troisième édition l’an prochain. Car, comme on connaît notre ami Legault, il ne lâchera pas le morceau.

Fly Solartech – A Pioneer Photovoltaic Products Manufacturer

Fly Solartech Solutions SRL, a pioneer solar panel manufacturer, has been engaged since 2013, in the research and development of photovoltaic products. With changing times, it is important to keep up with innovations to have an upper hand in the competition. But at Fly Solartech, it is the passion of developing photovoltaic modules and products that can be integrated into devices like wearables, public lighting, mobile devices, and many more.

With the increase in environmental degradation and scarcity of non-renewable resources, it could be a great choice to explore more of renewable energy resources. The main cause of importance here is the need to create photovoltaic panels that are easy to function with natural renewable sources of energy. Another thought that should be kept in mind is that the Solar Panel System should also be flexible to be utilized at any location which makes them more opted among people.

MANUFACTURING OF SOLAR PANELS

Our photovoltaic solar panels are created with attention to detail in the highest possible manner with the consideration of whether the product is competent technically and gives an aesthetic look or not. We are not just bound to competition in the market instead, our main focus is on creating ETFE Based Semi Flexible Solar Panel that are compatible to be used for the self-generation energy process. Our mission is to give quality to our life without impacting the current scenario. Our ETFE based Solar Panels are designed in a manner that they do not alter reality or affect others' lives.

By creating semi flexible solar panel that are high quality, is what we aim. Solartech’s most of the ETFE Solar Panels are designed in 7 layer technology, and comprise of anti-reflective ETFE surface, G-Wire Technolgy and use special materials such as thermoplastics or laminated fiberglass for manufacturing purpose. Due to the use of excellent materials, the Solar semi flexible panel have high corrosion resistance and structural strength even at a high-temperature range. Along with other such qualities, they also have excellent electrical, chemical, and high-energy radiation resistance properties.

Our Solar Power Panels are designed in Italy and are produced by using the most advanced technologies and best quality processing. These solar panels are the perfect Italian beauty with high efficiency that are easy to install and long-lasting.

RANGE OF PHOTOVOLTAIC PRODUCTS

Our range of photovoltaic products includes semi-flexible solar panels, solar street light solutions, and solar panels for commercial and residential purposes. The semi-flexible solar panels are most suited for use in boats. They are crack-resistant, lightweight, flexible, increased weather resistance, and many such qualities that make the semi-flexible solar panels for boats an excellent choice. Another category of photovoltaics is commercial and residential purpose solar modules. These modules come in a series depending upon the model. The main categories include Large Dimension Half Cell Mono Solar Modules and Large Dimension Mono Solar Module. Both the mono solar modules are perfect to be used in residential as well as commercial locations due to the characteristics like PID resistance, High Power Output, Better Low-Light Performance, 0~3% Positive Tolerance and strengthened mechanical support 5400 Pa Snow Load & 2400 Pa Wind Load. The bus bar half-cut cell with PERC Technology varies according to the modules.

One of the most innovative categories includes Solar panels for professional lighting that comprise of a variety of products like Easy SolarPole, Cylindrical Solar Panel, Single Cell Module, and On Top Solution. All these models can be utilized at different locations of the street depending upon the need of the fixing. The most important common factor in all of the solar panels of the Street Lighting category is that they are easy to integrate according to the needs.

Since our inception in the year 2013, we have focused on creating innovations that are beneficial to the people as well as the environment. With a wide range of solar collectors, we aim to fulfill all the needs of power in regards to solar energy.

Molarmiser

Something wedged itself in the doorframe when you weren’t looking. It’s roughly cylindrical, off-white, and seems to have sheared through the foundations and the ceiling, meeting in the middle, where you can make out an uneven seam. The two sections twist steadily in opposite directions. The bottom segment is rooted in a fleshy sheath, with a deep, dark hole at about waist height. “PUT” is written in angry red letters of scar tissue along its top circumference. A voice like a mosquito hovering just inside your ear chants canine, milk tooth, eye tooth, crunchy…

HD 11 MV nil AC nil (attacks hit automatically) AT gnash (3d6, if attack exceeds target Dex, target is seized in jaws and must make a Str check at disadvantage each round to break free or take d8 damage) Special surveillance, transposition, unyielding

Surveillance—the Molarmiser has direct access to the sensorium of every creature whose tooth it has consumed.

Transposition—the Molarmiser may switch positions with any creature whose tooth it has consumed once per round.

Unyielding—the Molarmiser is solid all the way through. Slashing and piercing attacks always deal half damage.

 It is possible that the Molarmiser is the only truly “native” form of life in Amnion, insofar as it seems to be some rogue element of Amnion’s organic superstructure—a particularly willful tumor, empowered by its direct line to the cosmic lifeblood that sustains the membrane between worlds. If it had more than a thin smear of brain cells to rub together, it would most likely be borderline omnipotent.

Fortunately, it is only arguably immortal, debatably omnipresent, and wholly committed to a deeply stupid purpose.

All the Molarmiser wants is teeth. Any moment it might spend without acquiring teeth is a wasted moment. All it understands is the acquisition of teeth; it lacks the empathy to understand why other creatures do anything besides furnish it with their teeth, and its personality simply isn’t complex enough to really get angry about being denied teeth either, though it will decide without hesitation to masticate anyone who gets too close and seems to be withholding teeth.

The trouble is that while the Molarmiser is single-minded, that doesn’t strictly mean it’s stupid in the conventional sense. It is stupid in the way a very strong artificial intelligence is stupid. It is quite good at getting what it wants with its limited toolkit.

It bargains for teeth in three ways: most often, it transposes itself somewhere hugely inconvenient and demands teeth in exchange for moving out of the way. In the presence of more streetwise travelers in Amnion, it offers a quick jaunt; once you’ve paid, it’ll shuffle you out with someone else in its network, covering ineffable distances near-instantly. Some who’ve done business with the beast enough to grasp its psychology and the extent of its power trade teeth for secrets—it knows everything that all its donors know, after all, though it may not understand and may take a gunny sack full of cuspids fed one by one and a battery of carefully phrased leading questions to coax out the desired information.

Some particularly foolish people worship the damn thing.

It speaks by modulating the perpetual grinding noise it makes as its upper and lower halves twist at glacial speed in opposite directions, steadily wearing down its collection.

The Anatomy of Melancholy, 35

Table of Contents. Second Instar, Chapter 2. Go to previous. Go to next. Do you believe in heaven above? *is shot*

So the chemist and his Mister Handy surveyed the junkyard for viable robotics specimens. Angel separated at times from its owner, to return and report back its findings, while ‘Choly annotated everything useful they located. Seven Mister Gutsies, five Mister Handies, and one Miss Nanny had been left here lacking well over half their parts. Dozens of heavily damaged Eyebots and Protectrons joined the General Atomics robotics scrap among the landscape of car shells which had hidden the true nature of the junkyard from street view. Though not G.A. in origin either, ‘Choly found an Assaultron head and flinched away from the skull-like cyclopean structure, only to stumble and nearly drop his coffee cup. Upon righting himself with his cane and catching his breath, he took a sip of his coffee, and his gaze absently drifted up to the wall of automotive carcasses. He’d located the prototype Sentry Bot, wedged among the rusted sheet steel stacked high to either side of it as though a child playing hide and seek in a stack of firewood.

He sputtered, choking on his drink. It had been two hundred years since he’d last seen one. Despite the base’s heavily classified security status, the Deenwood Compound relied heavily upon Mister Handy and Mister Gutsy accommodations, and only had three Sentries at their employ. True to his memory, the thing before him was, in essence, a sentient tank. A heavy tripod of mecanum limbs supported its hulking dark green body, its ocular sensor matrix was encased in a helmet-like dome recessed for the most part into its chest component, and its thick, broad arms terminated in a pair of miniguns. A mixture of relief and disappointment came when he recognized that it did not have mortar launchers in its shoulder components like those they had on base, and he found himself wondering which was the more advanced model. From the sound of the documentation on the terminal in the junkyard’s office, it had only been dumped here mere years before the nuclear exchange took place, so Deenwood’s Sentries in theory predated this one.

“Mister Carey, I believe we’ve identified the majority of resources on site, if you’d like to get started.” Angel paused beside its owner and looked where ‘Choly did. “I see!”

“From what I can tell, it’s a complete robot,” ‘Choly told it, vaguely nagged by his compulsions. “If it’s still got its Fusion Cores, it could be powered up...”

“Oh, but we shan’t be doing that. It’s forbidden by military protocols, and it’s RobCo tech besides.”

“...You’re right.” ‘Choly stared at his dress shoes a moment before looking to his Handy in earnest. “I know that I’ve made a promise to you, and that’s why I’m asking and not... pretty literally... going behind your back. Can I have one Berry Mentat for this task? I understand the way that Gutsy and Nanny parts can interface with those of a Handy, but I want to make this more than just a parts swap-out. I want to optimize what each component can provide you.”

“I imagined that your sobriety wouldn’t last long,” it resigned, to which its owner winced sheepishly. “Can we at least come to an arrangement, then, Sir? I shall dispense as requested, but you must keep your entire chem stock in my storage. If it’s too much to ask, for you to put me in charge of monitoring your chem usage, then I’m afraid I’ll have to decline the request.”

‘Choly smiled and put a hand to Angel’s pale blue spherical body.

“You drive a very hard, but very far, bargain. Let’s go inside, so I can sit while I strategize how to approach the upgrade.”

“Thank you for being reasonable.”

Once inside, Angel dispensed a single lozenge to its owner. Popping it under his tongue, he got to work scrawling schematics concepts on the back and front of a manila folder, and adding all kinds of notes wherever they would fit. This included a mix of G.A.-exclusive combinations and combinations with RobCo inclusions, though he had every intention to respect Angel’s boundaries--even if the warranty no longer mattered for all manner of reasons, it provided a very black-and-white understanding of what Angel was comfortable with ‘Choly doing to its body and programming. He finished off the coffee from the day before while he worked. They agreed that one of each tendril would be the ideal: a standard Handy limb, outfitted with an interchangeable laser, a saw, and a pincer; a standard Nanny limb, with an interchangeable pincer, a saw, and an injection tool; and a standard Gutsy limb, with an interchangeable saw, a laser, and a minigun. Barring locating sufficient 5.56mm and MF cell ammunition to keep the Gutsy arm equipped, the real task was optimizing the motherboard’s ability to wield any combination of these three at a moment’s notice, without overloading the processing speed. A standard issue Handy, Gutsy, or Nanny came optimized with programming to handle three of any one of the limb sets, not one of each. But, as he skimmed the programming with his Pip-Boy key-prong plugged into Angel, the Berries found a solution to the limbs’ shared compatibility which also facilitated the other element of the upgrades--its hydraulics capacity via its thruster calibration.

‘Choly requested Angel retrieve the required parts from the junkyard, and once they were amassed inside, he had the Handy mount the curved forks of the robotics workbench and switch off its pilot light. Then, he got to work, motivated by the creative impulses of the Berry Mentats.

“I’m sorry that we didn’t find any paint,” he started, while he finished tightening the bolts underneath Angel on its thruster core comprised of pieces from each model of robot, onto which he would re-mount the new set of tendrils. “You’ll have mismatched shell colors for a while. But, for what it’s worth, white, sky blue, and army green isn’t an unattractive combination.”

“I’m simply grateful that you’re taking all this time and effort on my behalf, Sir. I’ll never get used to the sensation of being physically incapable of movement. I know it will only last a few more hours at most, but I worry my speech module is compensating for my inability to move anything else.”

“We’ve already refilled your fuel tank. And done all the cutting and welding, like armoring the top curve of the tendrils with pieces of van wheel well arches. Protecting the joints will help deter them from getting severed again. --But with the modified core, attaching and calibrating the tendrils will go very quickly. What I’m most grateful for, though, is that I could welt those car door handles and a pair of motorcycle foot pegs onto you, so I can stop worrying that the fabric harness is going to rip off through wear.”

“I quite like the choice of Chryslus Coupe handles. They’re sleek and angular, in contrast to the smooth curves of my design.”

“I figured you’d notice the model I picked them from,” he grinned, getting started loading the tendrils one at a time onto their cylindrical chassis. “They’re not the ones from his Coupe, but I feel like his ghost would come to haunt me if I so much as considered touching his car.”

“He really is gone... isn’t he?” Even Angel’s voice grew distant.

“He was gone two hundred years ago,” ‘Choly replied without missing a beat, too detached from emotions by the effects of the potent nootropics to get distracted from his task. “The moment your biometric scanners could no longer recognize him, he was gone. You put what was left of him to rest, in the Red Rocket this week.”

“Forgive my sentimentality. I don’t intend to upset you, Mister Carey. I just... I know I’m merely an artificial intelligence, but I really do miss Mister Hawthorne.”

The chemist plugged in his Pip-Boy key-prong and got to working on calibration and maintenance scans.

“That makes two of us.” After a pause, he added, “It’s better, this way.”

“Agreed.”

“I’m glad we still have each other, Angel.”

“And I you. I hope it stays that way for some time. Not having either of you... I nearly fell apart before you resurfaced from the vault.”

“I’m glad I can still be here for you.” He smiled up at its ocular lenses. “I’ve optimized the programming for your new ocular lens armatures and sensors, as well as for your new thruster hydraulics and new tendrils. You’ll still have your Handy software, but it’s largely running with Gutsy and Nanny hardware. I have to power you down in order to initiate the maintenance scans, and then reboot you so that the system will pick up the new hardware. Are you ready?”

“I cannot wait to reawaken and understand for myself what humans mean when they see everything with new eyes.”

While Angel powered down, and the Pip-Boy ran its diagnostics with the robot turned off, ‘Choly couldn’t move from his place in the office chair beside the workbench, and, for lack of anything better to do tethered in place, he fished his flip lighter and a half-pack of menthols from his coat pockets. He didn’t smoke much, less than a pack a month, but sometimes his restlessness got the best of him. It was more about the ritual and paraphernalia than it was about the nicotine, and he readily admitted this. The irony glossed over him, that the Handy would have considered it a contraband chem in his possession, had it been alert to the behavior. The cigarette was out before Angel’s boot sequence initiated. He retracted the key-prong and watched. Angel’s tendrils seemed to stretch, and its three eye-stalks emerged from their concealed cutout plates to either side and front of its body.

“General Atomics International Mister Handy, 2066 model, nickname ‘Angel.’ Custom order serialization 33313222123123.” Angel registered its company, relit its pilot light, and dismounted from the workbench forks. “Good evening, Mister Carey!”

“How do you feel?”

“Like a new robot.” It sped forward, then side to side, and it inspected its tendrils with a seeming thoughtfulness. “It’s peculiar. The programming for Mister Gutsy and Miss Nanny parts has always existed to some capacity within my own programming from the beginning, but to feel more of it being executed. Would it be strange of me to speculate that it... it feels right?”

“You’re allowed to feel things,” ‘Choly grinned, proud of his work. “Let’s go out into the yard and see if there’s any more fine tuning we need to do with your new parts. You’ve got enough ammunition to do a little target practice, and I want to test out the soundness of the harness mounts. ...I know my opinion matters far less than your own, but I think your new look is pretty fetching.”

“I quite agree! These new ocular lenses have heightened sensory arrays in them, so I can see and perceive even behind me. I’m fascinated with all the details filling into my readings. Including a heightened understanding of what I look like. Dare I say, you’ve made me quite a bit more self-aware, Sir.”

“As long as you’re aware of how wonderful you are, I think we’re working in the right direction.”

Community Solar Rochester

Community solar in Rochester is a cost-effective, clean energy options

The rochester community solar is those tools which are utilized to take in the sun's rays and convert them right into electricity or warmth. A solar panel is a collection of solar (or solar) cells, which can be used to produce power via the photovoltaic effect. These cells are set up in a grid-like pattern externally of photovoltaic panels.

Rochester solar power is obtaining energy all over the world as increasingly more countries have begun transitioning to solar as a first power source. As the expense of solar power has dropped in recent times alongside significant renovations in technological effectiveness and manufacturing high quality, lots of homeowners are starting to check out solar as a viable alternate energy remedy.

Installation of solar panels in residences aids in combating the unsafe emissions of greenhouse gases and therefore helps reduce international warming. Solar panels do not cause any form of contamination and are clean. They also reduce our dependence on fossil fuels (which are limited) and conventional power sources.

community solar in rochester power is a renewable form of energy and therefore is sustainable energy. This suggests that the sun will undoubtedly show up somewhat regularly for life, so you can rely on this power always being there. Sure there will undoubtedly be evenings and overcast days, yet eventually, the sun will beam once more, and this "free form of the renewable resource" will be back for us to use. Oil is not a renewable resource, which means that when it's made use of, it's gone for life (it's in limited supply).

Solar power is created during the daytime (peak) periods of energy demand. This can be one of the most significant benefits of solar energy because this coincides amount of time your power business bills you one of the most cash to make use of power. So not just are you getting free power, your getting it when it would typically be most costly.

Human beings have utilized solar power since old times, and frequently progressing modern technology has exposed several brand-new applications for this unique, clean power. As using nonrenewable fuel sources remain to deplete the planet's natural resources, lots of people are wanting to the brand-new frontier of solar energy as both a popular option for a much better future and a worthwhile investment. The advantages of solar energy are numerous, and as technology advancements, the benefits continue to expand.

Advantages of going solar

1. Conserve Thousands of Dollars

2. Start Conserving from Day One

3. Low Repayment Period

4. Raise Your Home Value

5. Benefit From Rewards

6. Solar is a Secure Investment

7. Surefire Efficiency

These days, solar power in rochester ny are used in wide-ranging digital equipment like calculators, which function as long as sunshine is offered. Nonetheless, the only major drawback of solar panels is that they are quite pricey. Also, solar panels are mounted outdoors as they require sunlight to obtain billed.

Just How Do Solar Panels Job?

When photons strike a solar cell, they knock electrons loosened from their atoms. If conductors are connected to the favorable and unfavorable sides of a cell, it forms an electric circuit. When electrons move through such a course, they create electrical power. Several cells comprise a solar panel, and numerous panels (modules) can be wired with each other to create a solar array. The even more groups you can release, the more power you can expect to generate.

Exactly How Do Solar Panels Generate Electrical Power?

PV photovoltaic panels generate direct present (DC) electrical power. With DC electricity, electrons circulation in one instruction around a circuit. This instance shows a battery powering a light bulb. The electrons move from the unfavorable side of the cell, through the lamp, and go back to the silver lining of the battery.

With A/C (alternating present) power, electrons are pressed and pulled, occasionally turning around instructions, much like the cylindrical tube of a vehicle's engine. Generators produce Air Conditioner electrical energy when a coil of wire is spun beside a magnet. Several energy resources can "transform the handle" of this generator, such as gas or diesel fuel, hydroelectricity, nuclear, coal, wind, or solar. A/C electrical power was picked for the UNITED STATE electric power grid, mostly since it is less expensive to send over cross countries. Nonetheless, photovoltaic panels create DC power. How do we obtain DC electricity right into the AC grid? We utilize an inverter.

The necessary photovoltaic or PV procedure, as defined above, overcomes the following steps :

- The silicon photovoltaic solar cell takes in solar radiation

- When the sunlight's rays engage with the silicon cell, electrons begin to relocate

- Moving electrons develop a flow of the electric present, captured by nodes and wiring in the panel

- Wires feed this direct current (DC) electrical power to a solar inverter to be converted to alternating current (Air Conditioning) electrical energy

Solar power technology has been around for years. Solar provides a complimentary, trustworthy source of power to run a variety of tools, from radios and watches to powering your house. Nevertheless, most of us stay vague regarding the benefits of solar energy over other, nonrenewable power sources.

Solar Energy Conveniences

You can assist shield the environment currently and for future generations by producing your clean solar energy. Every solar power system we mount lowers the number of fossil fuels required to generate electricity, which consequently reduces the toxins contributing to international warming.

Solar power rge is an environmentally-friendly choice that minimizes your power costs, reduces the requirement for constructing new producing plants, and provides you the satisfaction of understanding that you are considerably benefiting the setting. Sustainable solar energy likewise contributes to reducing our country's dependency on international fuel, making solar energy the patriotic choice.

Fossil fuels are coming to be increasingly much more pricey as they are gradually diminished. As we seek the future, it's essential to take into consideration how much utility prices might raise over the following decade. Utility rates have boosted an average 13% every year over the previous five years, specifically. 

As demand for power increases and power generation sources are diminished, utility firm rates will inevitably raise. You are installing a solar energy system currently bushes versus future rate rises by using the renewable resource to supplement your electrical power demands. Your energy firm will indeed also thank you by paying you for each kilowatt of electrical energy you generate.

With your grid-tied solar electric system, you can sell any excess power back to the power business, successfully permitting you to spin your electrical meter in reverse. Furthermore, several utility businesses use a production reward enabling you to make money for the electricity you generate and use in your very own residence!

For Luck

For @otterandterrier‘s Scoundress Saturdays prompt - “Lipstick”

A/N: Knowledge of the Empire’s canonical Blackwing project is not necessarily required.  However, do know that zombies are canon in both the old Expanded Universe, and the current canon.  And Han and Chewie have had to deal with them in both. Sadly I don’t own any of this. And there’s really no zombies here.  But I have been a participant in a zombie march. :)

Many big squishy hugs and much thanks to @organanation, who patiently betaed this a year and half before I finally got the darn thing out. 

Timeline: Star Wars rebellion era, pre-Empire Strikes Back - existing within both canons.

______________________

“Stop complaining and waving yer arms. Chewie, your fur keeps getting caught in the cuff seal.” Han Solo’s heavy drawl echoed down the vessel’s starboard hall, as a petite brown-haired woman clad in a white jumpsuit strode towards the source of the noise. There was a muffled howl, and Han answered.

“Yeah, yeah. I’ll get my fishbowl sealed up, just hang on.” A whoosh of expressed air and just the shuffling of bodies sounded through the confines of the corridor.

The Rebel Commander, Princess Leia Organa, rounded the vessel’s starboard access corridor, which had become a temporary staging area for Han and Chewbacca’s EVA outing. Around the pair, were strewn a myriad assortment of a half-dozen mismatched lockers and cases.

The princess paused at the bulkhead, watching the pair of smugglers-turned-Rebel mercenaries. Leia acknowledged the Corellian and Wookiee with a nod. Settling against the alloy-steel support, she ran her eyes up and down the chaos of equipment and boxes scattered everywhere.

Both beings were now fully sealed in their Immediac model-10 extravehicular activity spacesuits. Han’s back was turned to her, the broad expanse of the pilot’s shoulders encased in numerous layers: of suit, the padded straps of his flak vest, harness webbing, life-support and Force-knows what else. He was preoccupied with inspecting the integrity of the locking ring on the neck of his two-and-a-half meter tall Wookiee partner’s custom-sized spacesuit as Leia stepped up a few steps behind him. Chewbacca barked at Han, the noise muffled and bowled. Han shifted and pivoted slightly to catch the Princess’s eye on the edge of his helmet’s field of view. She could just barely glimpse a corner of the upturned corner of his mouth as he quirked a grin in greeting. Then he winked.

Leia blushed, as surge of heat travelled through her body in response to the Corellian’s flirtations. She hated him for doing that to her.

Every time.

She bit back something hostile, and gave him a forced neutral look, eyebrows raised. Han shrugged and returned to his work. Leia, relieved that Solo turned and their eye-contact broken, settled for staring at his back.

And rear.

Oh, wow.

That, then, became an exercise in distraction, too.

In that moment, Leia decided that an EVA suit, despite its overall bulk, had never looked quite so… good, until it had been stretched over the rangy form of the attractive Corellian pilot working in front of her. The rather sleek black military-grade unit was agreeably filled out in all the proper dimensions by Han’s lean athletic frame. A signal-red, decimeter-wide stripe ran down the outsides of the torso, enhancing the suit’s lines. Damnit Solo, only a ridiculous flyboy like you could make one of those bulky things look sexy. She bit the inside of her cheek, stifling an admiring smirk. She had to admonish herself mentally to be serious.

Eyes front, Princess.

“Hey there, Princess.” Han’s gruff baritone echoed her title, the greeting rendered tinny and indistinct by the EVA suit’s sealed confines. He tugged experimentally on the wrist seal’s locking ring of Chewie’s glove. Chewbacca watched her, amused, from inside his helmet with kind, patient blue eyes.

She placed the three spare blaster-pistol charges Han had requested on the lid of a nearby case. Curious, Leia cracked open the lid of a larger aluminum case next to her leg, peeking inside, and sucked in a harsh breath upon viewing the contents. A well-worn SX-21 Merr-Sonn pump-action scatter blaster lay atop an array of more anti-personnel munitions; cluster grenades, wide-area frag launchers, and most worrisome -  high volume incendiary throwers. Each item designed to dole out maximum destruction over a concentrated radius in enclosed areas - such as inside the halls of a ship.

“Gods, Solo.” Leia whistled it out. “Are you looking to start another war?”

When there was no response, she looked up to see the boys fully absorbed in their final preparations. Sealed in their suits as they were, there was little chance they could have overheard her casual exclamation.

Chewbacca’s acute hearing seemed to have picked up Leia’s voice, however. He grinned, fangs glinting in the shadowed confines of the helmet. He punched a control on his glove and she saw the lights on the heads-up display inside of the Wookiee’s helmet reflect inside the bowl’s glass, detailing his furry face. Chewbacca barked amiably at Leia again and pulled on the buckle assembly of a thick harness he had strapped to his torso. Han’s attention went to the harness and tested the various straps and buckles by firmly tugging on them. He moved around to the Wookiee’s back and quintuple-checked the several monitors and gauges amidst the life-support array and various equipment packed on.

“All good there, buddy.” Han reached up and slapped the silver Millennium Falcon-shaped insignia patch on the side of Chewbacca’s shoulder, one of the few areas on his body not completely enclosed by harnesses and equipment. The Wookiee bent at the waist to pick up the beaten and worn end of the shoulder stock of a personal-sized heavy repeater cannon, attaching it to the cylindrical power supply on his back. He latched the housing of the weapon’s business end to a quick release clamp on the canister.

Satisfied with his preparations, Han stepped over to Leia, retrieving the spare blaster cells she had brought. He inserted them into the loops of his characteristic DL-44 pistol’s low-slung blaster rig, the leather belting refitted to accommodate the added volume of his spacesuit. He gave her a rakish look that put a small smile on her lips and lit a fire in her core.

“Thanks Princess.” Han’s voice was still distant and he said something else she couldn’t quite make out. Sensing her confusion, the Corellian rolled his eyes at himself, and made a sharp jutting motion with his chin, nudging the toggle inside the helmet.

“We’re pressured up and pretty much ready to go.” Han repeated, the sound emitting from a speaker in the control module near the center of his suit’s chest. He slung the strap of an Imperial-issue heavy blaster rifle over his shoulder, securing the strap with a hasp clip to a fixed D-ring on the webbing near his shoulder.

Leia shook her head at them. She reiterated what she had said a moment ago.

It would have been highly unusual for Han or Chewie to be unarmed. Han often carrying what would be considered a near-arsenal of weapons on a regular “safe” day - nearly all of it illegal in most civilized systems. The two smugglers had a lifetime of living on the fringes of society and legality. Never safe,always sleeping with one eye open. However, she noted that the Wookiee had abandoned his traditional bowcaster for the repeater cannon, something she didn’t even realize the two smugglers owned (owned being a purely euphemistic term with regard to the two widely-hunted Rebel criminals).

“Aah. No,” Han looked to Chewie, who was studiously ignoring the two humans. Han’s face was sheepish inside the helm. “We’re just not taking any chances, ya see,” he explained - rather lamely, Leia thought.

“—you wouldn’t tell command what this is about,” Leia reminded the two smugglers. “And yet, again, at the last minute you jump in and play hero.”

Han made a show of adjusting suit’s his wrist mirror, then threw his arms wide in frustration and pointed a black gloved finger at the Princess’s pert nose.

“Your skinny Festian buddy, Fulcrum–or whatever his name–got the info from me four years ago. That kriffin spook drugged me up and even got me to take him in front of Jab—“

Han shut up suddenly, and she could see his lips screw up in mid-rant.

Chewbacca turned his audio on and woofed at her and Han.

“What? In front of what?” Leia pressed, intrigued. “Who?”

Han shot a baleful eye at the Wookiee, who returned it unabashedly, glaring down at his captain, his dark lips curling up to reveal long fangs in challenge.

“He got you too, that night, buddy.” Han scowled, reminding his co-pilot of some past dereliction of duty.

Chewbacca snarled something in return. Leia could see Han stiffen in response, twisting his torso slowly and threateningly to stare up at the Wookiee that towered over the Corellian by two heads.

“Not another word about that,” Solo warned his partner. Chewbacca barked further and Han turned pink with embarrassment.

“He caught me at a weak moment.” The smuggler explained to his copilot.

Chewie’s next reply was mocking.

“Jenny was just being inhospitable that night, is all!” Han retorted angrily. Then his eyes flicked back to Leia and the Corellian went crimson. “Chewie…”

So, the Wookiee just laughed long and hard at his human friend. Leia rolled her eyes.

“If it helps your wounded ego,” Leia elucidated, then resumed in a wry tone, “or libido, “ she calculated, correctly, by the way Han nearly turned purple. “Captain Cassian Andor was one of our best spies. Actually, the best. Without him, “ Leia swallowed, pausing. Han’s gloved hand reached out to comfort her, recognizing her mood shift. Leia twisted to the right, side-stepping him, swiping at her cheek. “Without him, we would have never gotten the plans for the Death Star.”

Emotions such as regret, loss, anger and guilt swirled around Leia. So many “What ifs” lingered around the operation to uncover and destroy the Death Star. Entire cities were laid to waste before it turned its planet-killing laser onto her homeworld of Alderaan, killing billions. If, if, if…. Always with the ifs.

And now they were dealing with an Imperial superweapon that had been put aside around the same time. The rebel operative Andor had reported it then, as a low priority, though the entire sector associated with the project was declared “Absolutely Off Limits” in rare decree that spanned all levels of the Imperial Command structure.

Any ship that went in, did not come out. Period.

And somehow, by some act of Force-invoked coincidence, Han Solo and his co-pilot had gotten themselves entangled with whatever lurked there three years earlier, and were of only four people that emerged from the region in that time, pairing up to watch over each other and lose themselves in the wider galaxy. Four unlikely beings; a smuggler, a wookiee, an Imperial doctor, and an orphan boy - survivors who reportedly faced a ravening cannibalistic mass of recently deceased plague victims. A terrifying, all-consuming horror, apparently spawned by a bioweapon that exterminated all but one in a thousand humanoids.

The Rebel operative Andor was following various leads on Imperial superweapon projects, when he tracked down a rumor and discovered a traumatized and drunken Solo on Tatooine not long after.

Another, “If”, Leia counted on a finger. If the Rebel Intelligence service had put forward their files on this region of space to Command, before numerous scouting missions were dispatched to disappear amongst the floating wrecks, lives could have been saved. If they had first gone over the holos Andor had taken while interviewing Solo, they would have seen the fear in the battle-hardened Corellian smuggler’s eyes describing in drunken, disjointed speech, how would they have reacted?

“They were all… dead. Just piles of ‘em. Torn up. Then, then they woke up.”

“—Gray and flowing, following, looking for a way into you.”

“Just swarms of ‘em. Running, screaming….eating.”

“I could feel it coming in my lungs. The…The things it makes you think; all this red, hungry, gnawing.”

“I-, It almost got Chewie, he-, uh...uhm... the Doc intervened.”

“This, could take out entire sectors.”

Leia bit down the queasiness she felt recalling the hours viewing the holo-video, the blacked out lines of Imperial data files, and the Rebel scientists’ findings from Han and Chewie’s DNA tissue - samples Cassian Andor had stolen from the pair when he’d ambushed them in Mos Eisley. The conclusion sounded utterly insane, preposterous, a horror story for old-timers to tell younglings.

“Zombies…” Solo’s hissed warning, haunting Leia from Andor’s holos of him.

Simple adult logic told her it could not be true.

Leia ruminated about this mission. Just outside the adjacent hatch and airlock, floated the flickering derelict of an Alliance corvette starship. Han had cursed up and down in a dozen languages, grousing that this was too close already. Kept at a distant kilometer by a proximity lock from their vessel’s tractor beam, Han and Chewie adamantly refused linking the two vessels. Hence, was the necessity of an EVA outing for the two pilots to investigate the remains of the corvette.

For safety, they said.

For boarding a ship with just one lifeform aboard?

Han and Chewbacca were paranoid creatures of habit, but Leia had to admit she had never witnessed it this degree of extreme.

Upon an extensive and detailed sensor scan, – carefully monitored by Han and Chewie - they discovered that the three hundred beings recorded aboard the stricken Alliance craft beyond, had been reduced to the stubborn life-signature of one sole unknown humanoid, situated somewhere near the rear of the craft. Yet, the mass and density-signature scans showed the ship filled with clustered volumes of what could only be the remains of the crew and soldiers within.

Not only that... Han and Chewbacca had grudgingly acquiesced to Luke and Leia’s accompanying the mission, on the grounds - demands, Leia amended, - that the two smuggler’s preparations and procedures were not interfered with. Their word was law here. And that it was only the pair of them, out there.

Their orders too, hardly filled Leia with confidence, “If we come back, and we are not ourselves; sick, delirious, coughing, whatever... If there are no proper signal flares, or voice communications… If something is off, something is terribly, terribly wrong, - GO - cut the tethers and get the hell out of there. Do not, under ANY circumstances, attempt to rescue us.”

She had to promise, swearing upon the honor of the Royal House Organa, and repeatedly assure them that she and Luke would do as they requested if the circumstance arose.

And what was up with Luke? Leia fretted. Since arriving within system, Luke was a mess. Curled up in the cockpit; physically sickened by the Force’s signature in the area, the young rebel was in no condition to be enclosed in a spacesuit.

Luke said he’d recover shortly. He would just meditate through it. Saying, he’d be able to block it off in no time. He seemed to improve, until something had a softly thudded against the cockpit’s transparisteel glass outside, leaving a viscous red and grey smear. He’d yelped, distracting Han and Leia from their duties, rushing to fore to assist Luke. Han glared in horror at the smudge, clearly recognizing it. But the wide-eyed Jedi had waved them off, dismissing it, whispering something about space debris.

Han gave the kid a sympathetic look and resumed his preparations aft for the EVA, his mood grim for the next few hours.

Leia chose to avoid the surly Corellian for the afternoon, and spent a few timeparts sitting in the chair next to Luke, watching the shadows of dozens of derelict vessels beyond, as they drifted in front the glittering panorama of the brilliant field of stars beyond. They said little, communicating comfort through some unseen conduit.

Chewbacca’s lingering words from the intelligence briefing, roared at ear-splitting volume to the elite members of high council – shortly before Chewie and Han were temporarily locked up in the brig for (even louder) insubordination, and refusal to supply information on past experience with the area’s “Known unknowns,” as per General Cracken’s intelligence parlance – was translated and quoted, oh-so ominously and literally by the prim voice of Leia’s protocol droid C-3PO.

*Some things were not meant to be disturbed. *

The two-century-old Clone War veteran Wookiee’s grim warning looped over and over in the background of the Princess’s mind as she observed the present-Han secure the ship’s airlock’s safety tethers to their suits.

Pushing away from her lean against the bulkhead, Leia had to admit, she had a very bad feeling about this.

She watched Han gather up a satchel containing slicer kits, fusion cutters, clawed durasteel spreaders and truly archaic implements such as pry bars, and hammers. It was enough salvage and illegal ships’ hull-breaking tools to get the Wookiee and Corellian thrown in an Imperial penitentiary for at least a decade. Han passed a set to Chewbacca, who, after shouldering the bag, make a point of intently reviewing the energy level gauges on his weapon.

“See what you can bring back. “ Leia requested Han in sotto voce, she crossed her arms, not entirely sure what she actually expected. At the very least, she wanted them - needed him – back. Hopefully, they would locate what had to be that sole crew member on the life-scan, some logs, nav-data, or any evidence of why the months-overdue craft spun listlessly, here, near the feathered outskirts of Dathomir’s primary star’s Oort cloud.

“For you, your Worship; I would drag a star out of the sky.” Han bowed dramatically, paraphrasing an infamously corny Chandrilan poet for the Princess.

Grim atmosphere, or not; Han Solo could still extract a snigger from the implacable Princess Leia. Oooh, she hated him for that unique ability.

Han’s head popped up from the genuflection, his helmet’s heads-up displays illuminated the lower half of Solo’s ruggedly handsome features in a subtle shifting blue and green glow. And he winked…Again.

A warm surge spread across her cheeks, and Leia momentarily despised him for it…Again.

“Don’t do anything stupid, Nerfherder.” Leia cautioned, when she recovered her composure.

Han gave her his best comical Who, me?  expression, pointing two fingers at himself. But the humor didn’t seem to quite reach his eyes.

Impulsively Leia reached up, wrapping her slim fingers around Han’s EVA suit’s torso webbing. She hauled on it, dragging Han’s faceplate nearly level with her petite stature. She mused at his startled discomfit at her action. Craning her neck, she moved her face nose-to-glass with him. Han smirked ruefully at her, at the obvious literal and metaphorical barriers that seemed to always come up between them.

“Sweetheart, “ Han began, his voice gravelly, “I gotta tell y-“

Leia shook her head at him, the message obvious. We’ll figure us out later.

Leia clutched the sides of Solo’s helm, each studying the other,warring with the need to say what had to be said. To tip over into that beautiful abyss now, would shatter them both if something unfortunate happened here today.

Leia noticed the dull grey corona that had settled in the ordinarily glittering green and gold flecked irises of Solo’s deep-set hazel eyes. There was precious little of Han’s usual crazy bravado there now. And that, above all, frightened her.

She wanted to make him brave again, and by extension, herself.

Leia pursed and gently pressed her lips to the left edge of Han’s helmet’s glass, low down, near the neck seal, yet high enough for him to glimpse if he wished. When she withdrew, there remained the slightly smudged opaque print of her lipstick on the otherwise pristine exterior surface of the glass. Leia felt a blush rise to her cheeks, absently wondering how that had looked from inside. 

However, Han’s jaw dropped in pleasant surprise.

The Princess had extended a token of her favor to her champion.

Chewbacca woofed his approval as an aside, grinning toothily at the not-quite-a-couple.

Leia gave Han her most brilliant smile and he returned it, a crooked flash of gleaming white that made her breath catch, and heart pound. Han straightened, puffing his chest out, squaring broad shoulders in a determined set, the light finally reaching his eyes.

“For luck,” Leia added huskily.

“I know, “ Han murmured.
