Factorio: Space Age introduces the "quality" system, which you can technically play without, though I'm not sure it's balanced around that. I've now played with it enough that I have some thoughts on it.

First, I think it's kind of stupid that machines cannot naively use mixed-quality materials. It means that if you put a quality module in a single furnace, the lines will get "polluted" by the plates that are produced, and the whole factory will eventually gum up. Ask me how I know. I would vastly have preferred that it not matter: use a rare gear in a belt, and either it has no special benefit, or gives a chance to grant quality or something. But if it did that, I suppose it wouldn't be much of a gameplay challenge.

There are a few other pain points. One of them is that bots and the interface in general do not handle quality very well. Quality is almost always a strict upgrade, so it would be nice if there was a setting I could tick that said "hey, go upgrade things if possible". But instead, the UI and mechanics are such that you need to specify it, and this is super annoying, because it means that I have to manually go do the replacement myself, or have an upgrade planner to upgrade quality, then cancel the job once everything that can be replaced is so that the game will stop giving me an alert. I have accumulators and solar panels set up for quality right now, and I can't immediately think of a way to automate the process of upgrading the solar fields. I'm guessing that mods will help with that eventually. I also definitely want a keybind for "increase quality" and "decrease quality" on a machine, though I guess I never went looking to see whether that was a thing, so maybe it exists and I'm ignorant.

So as I see it, there are three main ways to engage with the mechanics:

Put quality modules in a machine that you're going to craft once and hope to roll high. The advantage is that hey, maybe you'll get lucky, and for stuff that goes in the equipment grid, I think this is sensible to do. Probably also wise for infrastructure, so long as you're fine doing some manual finagling that really should be done with bots.

Put quality modules in (some) machines that make intermediates, then use whatever you skim off the top there to make quality things. This does work, but you have to skim off essentially every single production line, and I think over time you end up with too much of certain things, which kind of sucks. It's one of the things that I've been doing, since it can guarantee the higher quality stuff, and ideally all the stuff in a spaceship and your equipment grid is at highest quality available. (You can also "skim" off anything you're making a shit-ton of for science: electric furnaces and yellow inserters are the two most obvious ones. I do wish this were easier to automate so that at some point you could say "actually, don't do the quality thing anymore". Probably some circuit logic could get you there, but you can't replace modules automatically that I know of.)

Use the recycler to "reroll" quality, making a gear over and over and over until it rolls high and can be separated out. The only issue with this is that it requires the recycler, and also is very expensive, but it does mitigate the randomness in its own way.

There's a secret fourth way that I've been noodling, which is that you could essentially build five separate copies of your base, put quality modules in everything, then if you roll high, send the better materials to the other base. This is insane, which is why I like it. So you would have miners mining with quality, which then gets separated onto five different trains and brought to the smelters, which then turn some fraction into higher quality plates that get sent to the "higher" factories. Those plates go into assemblers, which have a chance of upgrade, and so on, until there are five sets of labs, each of which is working with a different set of quality flasks. But I'm pretty sure that this would have a lot of technical problems, and really risk gumming up, as well as being very space inefficient and resource intensive. Still, might be workable end game, if you could deal with the inevitable overflows and imbalances.

Overall, I like it as a problem to chew on, but I think in practice they made a few decisions that I find annoying. Mods seem like they're fix some of it, like having to manually select upgrades, but the "clogging up the inventory" issue isn't going to go away, and in fact seems like one of the basic things that the mechanic is balanced around. I really appreciate that there are many ways to approach it, and that it creates this tradeoff of "go tall" or "go wide".

I'm very curious to see what people do with it, though I think the "throw vast resources into recycling" approach is probably going to be the dominant one unless there's a great blueprint for handling the overhead. And I'm also curious where public opinion is going to land on it, since it seems like the kind of thing that might end up divisive.

The use of femtosecond lasers to form glass-to-glass welds for solar modules would make the panels easier to recycle, according to a proof-of-concept study conducted by researchers at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL). The welds would eliminate the need for plastic polymer sheets that are now laminated into solar modules but make recycling more difficult. At the end of their useful lifespan, the modules made with the laser welds can be shattered. The glass and metal wires running through the solar cells can be easily recycled and the silicon can be reused. "Most recyclers will confirm that the polymers are the main issue in terms of inhibiting the process of recycling," said David Young, senior scientist and group manager for the High-Efficiency Crystalline Photovoltaics group in the Chemistry and Nanoscience department at NREL. Young is lead author of a new paper outlining the use of laser welds for solar modules. The paper, "Towards Polymer-Free, Femto-Second Laser-Welded Glass/Glass Solar Modules," appears in the IEEE Journal of Photovoltaics.

A group of scientists led by Kongu Engineering College in India investigated the use of waste neem oil as a cooling solution for PV modules. Neem oil is extracted from the seeds of the neem tree and is commonly used as a medicine for some skin diseases.

The researchers explained that this oil acts like phase-changing materials (PCMs), which can absorb, store, and release large amounts of latent heat over defined temperature ranges. PCMs have often been used at the research level for PV module cooling and the storage of heat.

“The neem oil has a good thermal range, is physically high in density, is chemically stable and noncorrosive, is environmentally pollution-free, reusable, and recyclable, and is economically low-cost and easy to dispose of,” they added. “Commonly, any PCM used for cooling purposes should have low thermal conductivity, stability, and cycling. The neem oil has fulfilled all the limitations.”

Mercedes-Benz is developing a new type of solar paint that could transform electric vehicle power. This photovoltaic coating, just 5 micrometers thick, covers 11 square meters. It can generate enough energy to power a car for up to 7,456 miles (12,000 kilometers) annually under ideal conditions.

The nanoparticle-based paint allows 94% of solar energy to pass through and is easy to recycle. It’s designed to be lightweight (50 grams per square meter) and can cover all exterior vehicle surfaces.

This solar paint, which contains no rare earth elements or silicon, is also cheaper to produce than conventional solar modules. The energy generated can be used to drive the vehicle or feed into the high-voltage battery even when the car is off.

This could mean no need to plug in for charging. The paint can be applied directly to the car’s body, with the color paint job sprayed over it to protect against scratches and other damage.

(The following article is a bit spoilery, but I've been working on this stupid concept for years and I just want to post it already. Still not happy with the design, but I can tweak it some more in the future. Since Ojio is a sci-fi geek, I wanted to give his invention a hokey retro futurist/anime flair.)

CHROMIGHT MECHASKEMA

OVERVIEW

The ChroMight Mechaskema(™) is a device invented by Ojio Paramonimos, founder of Chromight Technologies. It is a robotic body-augmentation that is custom tailored to its user. The mechanical framework permanently interfaces with the user’s nerves and organs, enhancing all bodily functions. Mr. Paramonimos himself describes it as “a mechanical shell”.

Once connected with the Mechaskema(™), users experience increased strength and speed, enhanced senses, and various other abilities which can be customized with modules, such as flight and water-breathing.

The Mechaskema(™) draws power from the user’s own energy reserves, meaning the user must eat more calories to accommodate extra power draw. Additional modules will draw even more power, and at a certain point it becomes impossible for the user to keep the device powered on calories alone. In these cases, additional power sources such as petrol, arcane crystals, or batteries must be used.

BENEFITS

Mechaskema(™) users (also known as “chromen” or “chromies”) enjoy a wide range of benefits from their mechanical parts. The device efficiently recycles calories into energy, eliminating the need to defecate altogether. Its blood purification system can filter disease and improve healing speeds, and may even allow the user to eat toxic materials with little to no harm.

The device can also slow the body’s aging process, but how much depends on which modules are used. This enables short-lived species such as trolls and minotaurs to enjoy longer lifespans. The device can also compensate for missing limbs and failing organs, effectively acting as a life-support system for sick users and allowing them to function normally.

In addition, the devices allow users to bypass the need for sleep using supplemental energy sources, giving them more waking hours for productivity or recreation.

Mechaskemas(™) are available in 2 models: basic and ultra.

The basic model offers many benefits and customization options, but is less powerful than the ultra model and cannot support as many modules. Its design is less invasive, leaving more of the user's flesh exposed and bodily functions unaltered. It may interact with some organs and other body parts, but not all of them.

The ultra model offers maximum benefits to the user and many slots for modules, but its heavy power draw can prove burdensome and even dangerous to the user if not managed properly. This model requires a supplemental power source to function, such as a battery. It is highly invasive, as it interacts with every part of the user's body.

SIDE EFFECTS

Mechaskemas(™) are a permanent body augmentation. Because they interface so heavily with the user’s biology, removing them is a fatal process. This also means that the user is at the mercy of the device’s core mechanisms, and should any of these mechanisms fail, the user may die or suffer severe biological damage. Broken mechanisms must be fixed or replaced promptly, but they are expensive, and this can only be done by skilled technicians.

Not everyone is a good candidate for a Mechaskema(™). The ideal user is a biologically mature adult, financially upper class, and technologically savvy. They should never plan to travel far from a ChroMight Technologies repair center, in case of a critical mechanism failure. The devices utilize several materials that are forbidden by the Nymph Pact, meaning chromen will struggle to survive in Great Kingdoms where the pact is in effect, and may be banned from those territories altogether.

Mechaskemas(™)  depend entirely on a power source. Calories, arcane energy, solar, petrol, or electricity are all options depending on the user’s model, but when these sources are not available, the device will begin consuming the user’s body. Allowing the device to run out of power leads to serious consequences, such as permanent bodily damage and even death.

In addition to food, the devices also require water to function properly. More advanced models require more water, which they utilize for cooling and other systems. Becoming dehydrated causes the device to malfunction and will lead to the user’s death if it is not corrected promptly.

Chromen experience increased hunger and thirst as a result of their mechanically-augmented bodies. Using supplemental power sources and water-management modules can mitigate these side effects.

The Mechaskemas(™) are mechanical devices, and as such they require maintenance. Regular oiling, polishing, and tune-ups will keep them functioning optimally, but failing to take care of these machines will lead to poor performance and possibly death to the user.

Over time, users will become more and more dependent on their devices to survive as their bodies begin to atrophy. Older users experience a phenomenon known as “module creep”, where they require more modules to keep themselves alive as time goes on.

Mechaskemas(™) are not free, nor are their power sources, replacement parts, modules, or maintenance. In fact these things are all quite expensive, so choosing to become a chroman is not a decision to be taken lightly. At a certain point, a chroman’s survival becomes entirely dependant on how much money they have for repairs.

MODULES

Each new Mechaskema(™) comes equipped with a set of standard features, depending on whether it’s a basic or ultra model. If users want more features, they must purchase modules. Modules are extra parts that attach to the device and enable more features. Each module draws additional power, and more sophisticated modules draw even more.

Some smaller modules can be added and removed without consequence. Others are more invasive and cannot be removed without killing the user.

Modules can perform a virtually endless number of functions. Each one falls under a broad category, and these categories include: Health, Utility, Defense, Energy, and Miscellaneous.

The following is a list of popular modules from each category:

HEALTH: Blood detoxifier, pacemaker, aging deceleration, synthetic womb, pain blocker

UTILITY: Enhanced strength, optical zoom lens, speed boosters, lights, artificial gills, wings, jetpack

DEFENSE: Armor plates, blades, guns, spikes, spell magnifier

ENERGY: Water tanks, fuel tanks, water vaporizer, fuel burner, solar panels, battery slots

MISCELLANEOUS: Radio, calculator, voice modulator, sexual enhancers, cosmetic modifications

CULTURE

Mechaskemas(™) are a novel technology in the world of Looming Gaia, and public opinion on them varies wildly. Some staunchly disapprove, viewing them as an insult to nature, and believe they will lead to allkind’s demise. Others support the technology, believing it can change many lives for the better.

Currently the devices are only available in Zareen Empire, but ChroMight CEO Ojio Paramonimos wishes to expand this technology to foreign lands in the future. Critics argue that chromen become entirely dependant on the company’s technology, and must keep surrendering more and more money to ChroMight Technologies as they become more dependent on their devices. Because of this, the company faces frequent protests and media scrutiny.

However, many corporations and even world militaries are very interested in Paramonimos’ creation, and have invested in his research in hopes that they can benefit from this novel tech in the future.

Mr. Paramonimos is under immense political, ethical, and financial pressure from all sides, and while his invention could possibly lead to disaster, he claims his only intention is to create a better future for allkind. He believes the marriage of flesh and machine will open the door to a safer, cleaner, and smarter tomorrow.

DP2 - Wandering Earth

Week 19:

This week I kept focusing on the workshop by first improving on the plan and then choosing three zones from the plan and designed the roof, facade and structural systems specifically to the environmental conditions required by each zone:

The south facing facade receives the highest level of solar radiation and activities including cutting and drilling take place in this zone, which can lead to overheating in the space, especially at summer. Therefore a layered strategy is implemented on the facade with dense and wide rain-fuel/solar panels acting also as shading devices which can result in effective cooling off the space.

The East Facing Facade provides excellent natural light in the morning and has a good view down the hill towards the city, therefore there are voids on the facades to provide opportunities for a balcony area. The facade panels are more curled up to further provide natural lighting and views as there are workbenches behind the east facade.

The North Facade in 2050 will encounter more severed environmental conditions as it receives poor natural light and is normally cold and damp. Therefore the facade panels are less dense to allow more light entering the space and more gaps on the roof to provide lighting. Deicing systems inspired by the aviation industry extends out from the roof to clean the icing that may form on the facade.

The Roof has different levels and grooves to direct the rainwater to drip down onto the facade elements and utilises its potential energy to regenerate energy; but also recycled into the bathroom to be reused. The roof has a curved shape that rises at certain points for lighting purposes.

I should keep working on these three design modules and use line drawings in combination with these renders to reveal the HVAC, structural and water systems of the space. Doing lighting and heating simulations on the interior space to prove the systems function properly

Key ideas mentioned:

Hollow tiles for heating and ventilation systems running through

shape the tiles so it guides the cool down streaming air around the furniture in the room

Pneumatically designed air exhaustion systems for manufacturing area (Reference to Zaha Science Museum)

Shelving systems on the facade to hang and dry the pieces manufactured in the workshop

Light pipes bringing light to the working area that is integrated with the furniture

furniture suspended from the ground with localized heating, water running through the furniture

Ramps connecting the buildings that extend out into the forest and foreshadowing the theme and emotions that the next building is going to bring to the visitors. Buildings get cut through similarly to canyons.

When presenting, show how spatial organization, facade systems and furniture systems are designed differently according to the hot and cold environment and lux levels.

Building a cargo spaceship capable of exploring our solar system based on current technology and the knowledge gleaned from our understanding of engineering, science, and chemistry requires us to work within practical and realistic constraints, given that we're not yet in an era of faster-than-light travel. This project would involve a modular design, reliable propulsion systems, life support, cargo handling, and advanced automation or AI. Here’s a conceptual breakdown:

1. Ship Structure

Hull and Frame: A spaceship designed for deep space exploration needs a durable, lightweight frame. Advanced materials like titanium alloys and carbon-fiber composites would be used to ensure structural integrity under the stress of space travel while keeping the mass low. The outer hull would be made with multi-layered insulation to protect against micrometeorites and space radiation.

Dimensions: A cargo space vessel could be roughly 80-100 meters long and 30 meters wide, giving it sufficient space for cargo holds, living quarters, and propulsion systems.

Cost: $500 million (materials, assembly, and insulation).

2. Propulsion Systems

Primary Propulsion: Nuclear Thermal Propulsion (NTP) or Nuclear Electric Propulsion (NEP):

NTP would involve heating hydrogen with a nuclear reactor to achieve high exhaust velocities, providing faster travel times across the solar system. NEP converts nuclear energy into electricity, driving highly efficient ion thrusters. Both systems offer relatively efficient interplanetary travel.

A hybrid solution between NTP and NEP could optimize fuel efficiency for longer trips and maneuverability near celestial bodies.

Cost: $1 billion (development of nuclear propulsion, reactors, and installation).

Fuel: For NTP, hydrogen would be used as a propellant; for NEP, xenon or argon would be the ionized fuel. It would be replenished through in-space refueling depots or by mining water on asteroids and moons (future prospect).

Cost (fuel): $50 million.

3. Power Systems

Nuclear Fission Reactor: A compact fission reactor would power the ship’s life support, propulsion, and onboard systems. Reactors designed by NASA’s Kilopower project would provide consistent energy for long missions.

Backup Solar Arrays: Solar panels, optimized for efficiency beyond Mars’ orbit, would serve as secondary power sources in case of reactor failure.

Cost: $300 million (including reactors, solar panels, and energy storage systems).

4. Cargo Modules

The cargo holds need to be pressurized and temperature-controlled for sensitive materials or scientific samples, while some holds could be left unpressurized for bulk materials like metals, water, or fuel.

Modular Design: The ship should have detachable cargo pods for easy unloading and resupply at different planetary bodies or space stations.

Cost: $200 million (modular design, pressurization systems, automation).

5. Life Support Systems

Water and Oxygen Recycling: Systems like NASA’s Environmental Control and Life Support System (ECLSS) would recycle water, oxygen, and even waste. These systems are key for long-duration missions where resupply may be limited.

CO2 Scrubbers: To remove carbon dioxide from the air, maintaining breathable conditions for the crew.

Artificial Gravity (optional): A rotating section of the ship could generate artificial gravity through centripetal force, improving the crew’s health on longer missions. However, this would increase complexity and cost.

Cost: $200 million (life support systems, with optional artificial gravity setup).

6. AI and Automation

AI-Controlled Systems: AI would manage navigation, propulsion optimization, cargo handling, and even medical diagnostics. Automated drones could be used for ship maintenance and repairs in space.

Navigation: Advanced AI would assist in calculating complex orbital maneuvers, interplanetary transfers, and landings.

Autonomous Cargo Handling: Robotics and AI would ensure that cargo can be efficiently moved between space stations, planets, and the ship.

Cost: $150 million (AI development, robotics, automation).

7. Communication and Sensors

Communication Arrays: High-gain antennas would allow for deep-space communication back to Earth, supplemented by laser communication systems for high-speed data transfers.

Radars and Sensors: For mapping asteroid belts, detecting anomalies, and navigating planets, advanced LIDAR, radar, and spectrometers would be necessary. These sensors would aid in planetary exploration and mining operations.

Cost: $100 million (communication systems, sensors, and diagnostics).

8. Radiation Protection

Water Shielding: Water, which is also used in life support, would double as a radiation shield around the living quarters.

Electromagnetic Shields: Experimental concepts involve creating a small electromagnetic field around the ship to deflect solar and cosmic radiation (early TRL, requires more development).

Cost: $50 million (radiation shielding).

9. Crew Quarters

Living Quarters: Designed for long-duration missions with the capability to house 4-6 crew members comfortably. The quarters would feature radiation protection, artificial lighting cycles to simulate day and night, and recreational facilities to maintain crew morale on multi-year missions.

Medical Bay: An AI-assisted medical bay equipped with robotic surgery and telemedicine would ensure the crew remains healthy.

Cost: $100 million (crew quarters, recreational facilities, medical systems).

10. Landing and Exploration Modules

Surface Exploration Vehicles: For landing on moons or planets like Mars or Europa, a modular lander or rover system would be required. These vehicles would use methane/oxygen engines or electric propulsion to take off and land on various celestial bodies.

Cost: $300 million (lander, rovers, exploration modules).

---

Total Estimated Cost: $2.95 Billion

Additional Considerations:

1. Launch Vehicles: To get the spacecraft into orbit, you would need a heavy-lift rocket like SpaceX’s Starship or NASA’s Space Launch System (SLS). Multiple launches may be required to assemble the ship in orbit.

Cost (launch): $500 million (several launches).

2. In-Space Assembly: The ship would likely be built and assembled in low-Earth orbit (LEO), with components brought up in stages by heavy-lift rockets.

Cost: $200 million (orbital assembly infrastructure and operations).

---

Grand Total: $3.65 Billion

This estimate provides a general cost breakdown for building a cargo spaceship that could explore and transport materials across the solar system. This concept ship is realistic based on near-future technologies, leveraging both nuclear propulsion and automation to ensure efficient exploration and cargo transportation across the solar system.

Callsign: Archon

Chapter One, Part Six

Arriving in the mech bay had been impressive enough; it was practically large enough to house an entire work segment of one of the stations, with four slots to a side - six of them occupied by mechs suspended in shock cradles. Framed by Ashes and Knight, she hadn't seen Archon sweeping in from the side, no until the redhead had plucked her from between the two and spun her around to face the least colorful of the mechs.

"Well, Mirror? What do you think, station girl? Your very own Everest, freshly assembled from the printer and awaiting your decisions to name, decorate, and outfit it." A push at her back, sending her stumbling toward it. "Go on, meet your new best friend!" The three veterans had shown her how to operate the lift and board the nameless mech, and so she'd done as they told her.

And now she sat in the quiet of the cockpit, carefully going through the boot sequence for the systems, following every prompt with the diligent care of station life. The soft hum of fans turning on, the bone-deep vibration as the reactor core came to life, the slow spread of lights starting at red and slowly fading across the spectrum to a green more lovely than any plant from the aeroponics modules; all of it whispering to the little girl who still lived deep inside her.

A prompt on the main screen; "Option: download standard operation NHP or upload personal module?"

She hesitated just before the acceptance - and drew her hand back, digging in the pockets for her personal data slate, the one she was supposed to return to be recycled by the station and never would now. She connected it to the mech's systems and gave the prompt the address of a file on it.

"Caution: Nonstandard NHP profile. Confirm upload?"

She confirmed, and watched the file upload into the casket of the mech. It wasn't a NHP; it was barely even a smart program, but it was something she'd built herself, a software aid she'd planned to use while working on the neutrino telescopes.

"V.I.S.I.O.N. uploaded. Boot shackling systems?"

Another confirmation.

A strange vibration rippled through the mech as the casket came online, ready to bind a full-blown NHP to causal reality and finding only a small piece of software rattling around inside the massive cage. The systems, adaptive, adjusted to give it the processing capacity it required, and then some, folding causality in around it in ways that would have fit a proper NHP but leaked slightly around it.

Unaware of what she'd just catalyzed, Julie returned to the rest of the boot sequence, and eventually hit a final one-time prompt. "Enter pilot callsign and mech name."

Her callsign went in almost more readily than her actual name ever had. As for the mech… She nodded. VISION, she entered, figuring it was a nice tribute to her soon-to-be-overworked program, unaware that something already observed the name and felt a tiny spark of joy at being recognized.

The comm cracked as a line opened, and one of the sisters - Ashes, she suspected, from the less-formal speech - came across it. "Mirror! If you are done there, come have a say with us! We are arguing with Archon over colors for your mech, eh, Vision. She wishes to paint it solar yellow, we say that if you are to be our new specialist in obscuring sensors you deserve more fitting hues such as black or silver. Come, tell us your pick! Even Archon will not deny you the right to your own choice of colors."

Unaware of the small awareness evolving inside the casket, Julie laughed and keyed the comm open from her end. "Just a moment! Let me power down the mech and I'll come choose!" It was, in a sense, the final closure of the door on her planned life; choosing her colors and marking the mech as hers, a thing too big for any station to support and too dangerous to let exist by itself in the system.

Mirror let herself out, and rode the lift down as the Everest ran through its automated shutdown sequence.

What Happens to Solar Panels Once They've Reached End-of-life?

Solar energy is a fast-growing energy system and the most popular renewable energy source. The solar energy movement began decades ago, but its popularity and utility have increased due to government promotions, organizations' support, and customer attempts to reduce the use of traditional energy sources like electricity and fossil fuels.

Can MPPT Work On Lithium Batteries?

What is the advantage of the lithium battery?

As we known, there are many kinds of batteries in the market, most use are the lithium battery and the lead-acid battery. Now the lithium battery is more and more popular because of the much longer recycle times than the lead-acid,which can be up to be 3000 times even more.

There are more advantage of the lithium battery, when the lithium battery add the BMS(Battery management system), the lithium can manage the charging voltage and the discharge, can protect your battery from the over charging and discharging.

What is the MPPT?

In the solar power system,the solar charge controller is the solar kits that between the solar panels and the inverter or battery, after the solar panels generate the electricity, then the solar charge controller will stabilize the voltage and the current,which will charge the battery safely.

For the solar charge controller, there are MPPT and PWM solar charger controller optional, Why the MPPT is better?

We need to know what is "maximum power point". Under the same lighting conditions, photovoltaic modules will have different output currents at different operating voltages. When the photovoltaic module works at a specific voltage, the product of the specific voltage and the output current (that is the power) reaches the maximum value. This operating point is the maximum power point, and it is also the time when the photovoltaic module generates the highest power generation efficiency.

MPPT solar charge controller can detect the power voltage of photovoltaic modules in real time, and track the highest voltage and current values, so that the photovoltaic power station can track the maximum power point under different sunshine and temperature environments, so that the system can output maximum power.

Rather than the PWM solar charge controller, the MPPT has a higher convert efficiency that can be up to be 99%.

Can the MPPT work with lithium battery?

It is no problem for the MPPT to work with the lithium battery. In fact, our MPPT can work with all kinds of the battery. In the market, the data sheet of different lithium factory is differnt (including the charging voltage, high voltage protection and the low voltage protection and so on). So before leaving the factory, the MPPT can be set the charging parameters according to the data sheet of the lithium battery.

Welcome to Prefab Profiles, an ongoing series of interviews with people transforming how we build houses. From prefab tiny houses and modular cabin kits to entire homes ready to ship, their projects represent some of the best ideas in the industry. Do you know a prefab brand that should be on our radar? Get in touch!For architect and Majamaja cofounder Pekka Littow, designing a seaside retreat in Finland was an exercise in showing people the potential of self-sustaining homes to reduce our reliance on resources. The first cabin at Majamaja Village was built in 2020, and there are now a total of four along a picturesque slice of coastline overlooking the archipelago outside Helsinki.Because there are no roads or hookups there, minimizing the retreat’s impact on the environment was critical. The cabins’ prefabricated elements, including the vertical wood cladding and crisp gables, make them easy to dismount while lending them a Nordic aesthetic. Less immediately visible is each cabin’s patented sanitary module that, in combination with solar panels, wind generators, and gray water systems, allows them to operate independent of city infrastructure.While each cabin is its own accommodation, communal living is at the core of the company’s ethos. "The Majamaja philosophy believes in people’s ability—and even their essential need—to live in community," says Littow. "This village creates a sense of security and allows for social interaction for those who desire it."Read on to learn more about Majamaja Village and what it takes to build along Finland’s craggy coastline.The cabins at Majamaja Village outside Helsinki don’t rely on city infrastructure and are constructed almost entirely form solid wood prefab elements.Tell us about the retreat. What was the idea behind it? Majamaja is an example of how the energy, water, and waste management required for living can be handled locally. The future goal is to demonstrate that it is possible to transition to off-grid living on a broader scale. Majamaja is already exploring solutions that serve larger living units and village complexes. I think that in the future, self-produced energy or internal water-treatment systems for apartment buildings will be as common as any other fixture or appliance. The eco-retreat opened in 2021 in a portion of the area’s archipelago with no road access or ground sanitation.Why did you chose prefab for these homes?Building on-site would not have been possible without the self-sufficiency of the cabins. The site lacks municipal infrastructure, and the city had no intention of providing it due to costs. Self-sufficiency means we could avoid harming the landscape with excavation or aerial cables.Thanks to the self-sufficiency technology integrated into the sanitary module, no ground modifications are needed. Building this way also saves time, as construction can begin quickly, and actual use can commence soon after. Because the cabins are delivered fully prefabricated to the site, and the manufacturing process is industrial, rational, and controlled, the on-site assembly time is short. The cabins can be divided into smaller elements for delivery; for the Helsinki project, they were brought in by ferry, so the natural surrounding stayed almost entirely intact.Space-saving solutions in the 235-square-foot cabins include fold-away dining tables and benches.Tell us more about the cabins’ off-grid capabilities.Majamaja achieves self-sufficiency through solar panels, wind generators, or, at times, a fuel cell. Clean water is produced from salty or gray water using an on-board water purification system. Water is treated and returned to nature or recycled for reuse. Dry toilets convert human waste into a soil conditioner. All the cabins’ building technology, as well as energy and water storage, is integrated into a sanitary element that is internationally patented.Why is important that these cabins are self-sufficient?Majamaja brings energy and water management as close as possible to the end user. The specificity of the systems increases awareness of the limited nature of resources and the impact of one’s actions on them. It allows for managing waste disposal as well as water and energy consumption by changing personal habits. The benefits achieved through one’s own actions are personal, immediate, and visible.The cabins have lofted sleeping areas.Do you offer these units for sale?We have several units. The base model is a 23-square-meter (approximately 248-square-feet) cabin located in Helsinki, which accommodates three people. Soon, we’re building a 40-square-meter (approximately 430-square-foot) model that includes sleeping arrangements for five and the option for a private sauna. A third cabin has been designed for areas requiring air conditioning. The price of the current models ranges from €80,000 to €250,000 (approximately $83,450 to $260,790 USD), depending on the unit and desired building technology.For the project extension in the island location, we will be selling 40-square-meter family units with private saunas and the possibility to rent it through Majamaja. The pricing will vary between €300K and €400K per unit (approximately $312,950 and $417,264 USD), which includes the land.We also recently launched a Majamaja membership program where you can invest in co-ownership shares of the Helsinki village. The program offers members usage rights and rental income, and the initial pricing starts at €18,500 per share (approximately $19,300 USD).How long can a client expect the process to take after they put down a deposit?The prefabrication of five cabins takes about four months. The setup of one cabin, including all finishings, takes about five working days.Each cabin has a patented kitchen module coupled with energy storage and a wastewater system that allow it to operate off-grid.Where are your designs currently available? Currently, we have building partners in Finland and France. We deliver throughout Europe and even further by sea transport. It is possible to purchase just the plans for a local builder to use, or to order just the self-sufficiency technology, if someone wants to use it in their own design. The sleeping areas look down into the living spaces.What aspects of an install do you manage?  We organize the construction and delivery of the cabins to the client, while a builder’s team performs the assembly on-site. For the building permit, we provide the necessary architectural plans, which the local operator finalizes according to local requirements. The same is done for electrical and plumbing plans if the buildings are delivered outside Europe. We provide basic plans for the foundations, which are then completed by local contractors. The cabins were assembled without the use of heavy machinery. Source link
