Year is going by so damn quick

Almost choose my regular summer sets- but instead went with the Rush session 👉👈 replayed that song way too much (welp I'm listening to it right now even) Babes dancing glued to each others 😌

The pic from 2021 was actually my first The Star ending swap! Mitch being the played character and Valentin swapped into Panam, during the ending cinematic 😩 it's such a sweet scene, seeing the blorbos move, touch and look each others in a ""natural""/automatic way just hits DIFFERENT

2022 was- if I remember correctly- from the preview set of the first Dad Shirts batch! 😊 Without any surprises, I wanted Mitch to have a summery outfit, that's how the Dad shirt mod came to life (he's really the reason for a loooot of mods, uh)

Athletes Go for the Gold with NASA Spinoffs

NASA technology tends to find its way into the sporting world more often than you’d expect. Fitness is important to the space program because astronauts must undergo the extreme g-forces of getting into space and endure the long-term effects of weightlessness on the human body. The agency’s engineering expertise also means that items like shoes and swimsuits can be improved with NASA know-how.

As the 2024 Olympics are in full swing in Paris, here are some of the many NASA-derived technologies that have helped competitive athletes train for the games and made sure they’re properly equipped to win.

The LZR Racer reduces skin friction drag by covering more skin than traditional swimsuits. Multiple pieces of the water-resistant and extremely lightweight LZR Pulse fabric connect at ultrasonically welded seams and incorporate extremely low-profile zippers to keep viscous drag to a minimum.

Swimsuits That Don’t Drag

When the swimsuit manufacturer Speedo wanted its LZR Racer suit to have as little drag as possible, the company turned to the experts at Langley Research Center to test its materials and design. The end result was that the new suit reduced drag by 24 percent compared to the prior generation of Speedo racing suit and broke 13 world records in 2008. While the original LZR Racer is no longer used in competition due to the advantage it gave wearers, its legacy lives on in derivatives still produced to this day.

Trilion Quality Systems worked with NASA’s Glenn Research Center to adapt existing stereo photogrammetry software to work with high-speed cameras. Now the company sells the package widely, and it is used to analyze stress and strain in everything from knee implants to running shoes and more.

High-Speed Cameras for High-Speed Shoes

After space shuttle Columbia, investigators needed to see how materials reacted during recreation tests with high-speed cameras, which involved working with industry to create a system that could analyze footage filmed at 30,000 frames per second. Engineers at Adidas used this system to analyze the behavior of Olympic marathoners' feet as they hit the ground and adjusted the design of the company’s high-performance footwear based on these observations.

Martial artist Barry French holds an Impax Body Shield while former European middle-weight kickboxing champion Daryl Tyler delivers an explosive jump side kick; the force of the impact is registered precisely and shown on the display panel of the electronic box French is wearing on his belt.

One-Thousandth-of-an-Inch Punch

In the 1980s, Olympic martial artists needed a way to measure the impact of their strikes to improve training for competition. Impulse Technology reached out to Glenn Research Center to create the Impax sensor, an ultra-thin film sensor which creates a small amount of voltage when struck. The more force applied, the more voltage it generates, enabling a computerized display to show how powerful a punch or kick was.

Astronaut Sunita Williams poses while using the Interim Resistive Exercise Device on the ISS. The cylinders at the base of each side house the SpiraFlex FlexPacks that inventor Paul Francis honed under NASA contracts. They would go on to power the Bowflex Revolution and other commercial exercise equipment.

Weight Training Without the Weight

Astronauts spending long periods of time in space needed a way to maintain muscle mass without the effect of gravity, but lifting free weights doesn’t work when you’re practically weightless. An exercise machine that uses elastic resistance to provide the same benefits as weightlifting went to the space station in the year 2000. That resistance technology was commercialized into the Bowflex Revolution home exercise equipment shortly afterwards.

Scientists have developed a new solar-powered system to convert saltwater into fresh drinking water which they say could help reduce dangerous the risk of waterborne diseases like cholera.

Via tests in rural communities, they showed that the process is more than 20% cheaper than traditional methods and can be deployed in rural locations around the globe.

Building on existing processes that convert saline groundwater to freshwater, the researchers from King’s College London, in collaboration with MIT and the Helmholtz Institute for Renewable Energy Systems, created a new system that produced consistent levels of water using solar power, and reported it in a paper published recently in Nature Water.

It works through a process called electrodialysis which separates the salt using a set of specialized membranes that channel salt ions into a stream of brine, leaving the water fresh and drinkable. By flexibly adjusting the voltage and the rate at which salt water flowed through the system, the researchers developed a system that adjusts to variable sunshine while not compromising on the amount of fresh drinking water produced.

Using data first gathered in the village of Chelleru near Hyderabad in India, and then recreating these conditions of the village in New Mexico, the team successfully converted up to 10 cubic meters, or several bathtubs worth of fresh drinking water. This was enough for 3,000 people a day with the process continuing to run regardless of variable solar power caused by cloud coverage and rain.

[Note: Not sure what metric they're using to calculate daily water needs here. Presumably this is drinking water only.]

Dr. Wei He from the Department of Engineering at King’s College London believes the new technology could bring massive benefits to rural communities, not only increasing the supply of drinking water but also bringing health benefits.

“By offering a cheap, eco-friendly alternative that can be operated off the grid, our technology enables communities to tap into alternative water sources (such as deep aquifers or saline water) to address water scarcity and contamination in traditional water supplies,” said He.

“This technology can expand water sources available to communities beyond traditional ones and by providing water from uncontaminated saline sources, may help combat water scarcity or unexpected emergencies when conventional water supplies are disrupted, for example like the recent cholera outbreaks in Zambia.”

In the global rural population, 1.6 billion people face water scarcity, many of whom are reliant on stressed reserves of groundwater lying beneath the Earth’s surface.

However, worldwide 56% of groundwater is saline and unsuitable for consumption. This issue is particularly prevalent in India, where 60% of the land harbors undrinkable saline water. Consequently, there is a pressing need for efficient desalination methods to create fresh drinking water cheaply, and at scale.

Traditional desalination technology has relied either on costly batteries in off-grid systems or a grid system to supply the energy necessary to remove salt from the water. In developing countries’ rural areas, however, grid infrastructure can be unreliable and is largely reliant on fossil fuels...

“By removing the need for a grid system entirely and cutting reliance on battery tech by 92%, our system can provide reliable access to safe drinking water, entirely emission-free, onsite, and at a discount of roughly 22% to the people who need it compared to traditional methods,” He said.

The system also has the potential to be used outside of developing areas, particularly in agriculture where climate change is leading to unstable reserves of fresh water for irrigation.

The team plans to scale up the availability of the technology across India through collaboration with local partners. Beyond this, a team from MIT also plans to create a start-up to commercialize and fund the technology.

“While the US and UK have more stable, diversified grids than most countries, they still rely on fossil fuels. By removing fossil fuels from the equation for energy-hungry sectors like agriculture, we can help accelerate the transition to Net Zero,” He said.

Time limit premise in Ikemen series... and why Vamp is the worst in that sense

Don't misunderstand, I really like Vamp and this has nothing to do with my personal likes.

So the setting of each Ikeseries game from Cybird is like this

Sen: MC who time traveled, 3 month time limit

Rev: MC who went to another world, 1 month limit

Vamp: MC who time traveled, 1 month time limit

Ĺive: MC who was living in that world, no time limit

Gen: MC who was living in that world, no time limit

Pri: MC who was living in that world, 1 month time limit

Vil: MC who was living in that world, 1 month time limit

And among these, the one that this time limit premise is done in the poorest way is Vamp.

This is mostly because MC has only a month(or two, in the later routes but still) and once she leaves she can never come back.

Well, ok you could fall in love in a month, that's acceptable, but giving up your whole life in 21st century for the dude who you've only known for a month? To make matters worse, this MC is good at speaking multiple languages but it's just necessary for everyday life, not like it helps her significantly or makes her a job. The only thing she does in 19th century France is to do chores with Sebastian. I mean, of course that's an important work, yes, but... it has nothing to do with her specialties or dreams or anything. In the worst case scenario if she breaks up with the dude, her choice to be with him leaves her nothing. She just wasted her time doing chores in the random mansion.

At least Sen MC has 3 months, which is absolutely better than one, and she actually has a proper job to do with her specialty in that timeline.

Rev MC is from another world but going back and forth between her world and the guy's isn't very much of a big deal compared to Sen or Vamp. Just wait for a month and she could always go to another world and vice versa.

Live and Gen MCs are in the same world with the guys and don't have any kind of time limit so they have nothing to be bothered.

Pri and Vil MCs have 1 month time limit, but still they're in the same world with the guys so they could always meet even after the deadline, if they really wanted to.

But Vamp MC only has 1 month, and she'll never see the guys again once she leaves that timeline. So she's like "Oh I love him so much, I don't wanna leave him" but 1 month is not enough time to decide whether you could give up all you had including careers, dreams, family and become the housekeeper only for the sake of love.

And this isn't Cybird's game, but Court of Darkness from Voltage has a similar setting, MC going to another world(without the time limit). And at least this MC is an orphan and she mentioned herself that no one will be there for her even if she went back. So it's more acceptable that she chose life in new world, since it's pretty much indicated that she doesn't have much attachment to her previous world.

But Vamp MC? She has family. She has friends. She has job. Why in the world would she abandon all those just for a guy she had just met.

Reviving Tesla’s Dream: The Future of Wireless Power Transmission

“My project was retarded by the laws of nature. The world was not prepared for it. It was too far ahead of time. But the same laws will prevail in the end and make it a triumphal success.” – Nikola Tesla

In the early days of radio technology, there was a crucial decision point that split wireless technology into two distinct paths. One path, pursued by Marconi and others, focused on electromagnetic wave transmission. The other path, championed by Nikola Tesla, aimed to minimize electromagnetic waves and use the Earth itself for energy transmission. While the world predominantly embraced the former, Tesla’s innovative approach was largely forgotten. Let’s explore Tesla’s lost art.

Tesla's wireless power transmission system, often known as his "Magnifying Transmitter," was a pioneering approach to sending electrical energy over long distances. Unlike today’s wireless technologies, which rely on electromagnetic waves, Tesla's design aimed to transmit energy through the earth, which he believed was more efficient.

Tesla showcased his system’s potential during his 1899 experiments in Colorado Springs. He successfully transmitted energy through the ground, illuminating bulbs about a mile away from the transmitter. Tesla saw this as a matter of engineering: just as a machine that can throw a rock 5 feet can be engineered to throw it 1,000 feet, he believed his system could be adjusted to transmit power across any distance on Earth.

Modern wireless technologies, such as radio, Wi-Fi, and cellular networks, use electromagnetic waves that spread outward from a source. These waves lose strength according to the inverse square law, which means signal strength decreases with the square of the distance from the source. This energy loss is a significant limitation for long-distance communication and power transmission.

Tesla’s vision was quite different. He recognized that while electromagnetic waves were effective for communication, they were inefficient for transmitting large amounts of power. As he put it, “I only used low alternations, and I produced 90 percent in current energy and only 10 percent in electromagnetic waves, which are wasted.” Tesla aimed to minimize electromagnetic radiation, which he considered to be energy-draining. Instead, he focused on transmitting energy through the earth, which he believed was more efficient and recoverable.

Tesla's system utilized a large coil known as the "Magnifying Transmitter," which generated a high-voltage, low-frequency current. This design featured significant self-inductance and minimal capacitance, producing a strong resonant effect. By accumulating and directing massive amounts of energy with minimal losses, Tesla aimed for efficient power transmission. As he explained, “I accumulate in that circuit a tremendous energy... I prefer to reduce those waves in quantity and pass a current into the earth, because electromagnetic wave energy is not recoverable while the earth current is entirely recoverable, being the energy stored in an elastic system.”

The scientific principles of Tesla's system include:

1. Resonant Circuits: Tesla's system used resonant circuits, tuning the primary and secondary coils to the same frequency. This resonance allowed for efficient energy transfer between coils, amplifying energy while minimizing losses.

2. Self-Inductance: A key component of Tesla’s system was self-inductance. A large coil with high self-inductance generated a strong magnetic field essential for creating high-voltage, low-frequency current. Self-inductance helped store energy in the coil’s magnetic field, critical for high power levels.

3. Capacitance: Tesla’s design involved large capacitors to store electrical energy. Capacitance was kept small compared to self-inductance to achieve desired resonant effects. The capacitors would discharge rapidly, creating high-voltage pulses for transmission through the earth.

To construct a system similar to Tesla’s, he advised:

1. Low Frequency, High Voltage Design: Build a large Tesla coil to generate high voltages at low frequencies. Ensure the design minimizes electromagnetic radiation and focuses on efficient energy transfer into the ground.

2. Loose Coupling for Resonance: Use loose coupling between the primary and secondary coils to achieve significant resonant rise. The coils should be inductively linked but not too close to avoid direct energy transfer.

3. Earth Connection: Establish a deep, effective ground connection to allow the transmitter to send electrical currents into the earth, utilizing its natural conductive properties.

4. Minimizing Radiation: Design the system to suppress electromagnetic radiation, aiming to retain energy within the circuit and direct it into the ground. Tune the system to maximize energy storage and transfer.

5. Energy Storage and Discharge: Incorporate large capacitors for storing and rapidly discharging energy to create high-voltage, low-frequency oscillations.

Tesla’s system faced significant challenges, including the need for large, expensive equipment. In 1914, he estimated the cost of his "Magnifying Transmitter" at $450,000—around $15 million today. These financial constraints prevented him from fully realizing his dream and unfortunately led to his public image as a mad scientist with unrealistic future visions. However, the potential applications of his system are vast, from global wireless power transmission to reducing infrastructure costs and powering remote areas. With ongoing advancements in technology, Tesla’s vision may be within reach.

Tesla’s system presents an alternative approach to wireless energy transmission, focusing on efficiency and long-distance power transfer over the broad dispersal of electromagnetic waves. While modern technologies have advanced in different ways, Tesla’s principles—especially his focus on resonant circuits and earth currents—provide valuable insights into alternative methods of energy transmission. Exploring these principles today could lead to innovative applications, such as more efficient long-distance power transmission or new energy transfer methods.

Ooh my brain accidentally read electro kink as us putting tweels in shock collars

>:D

ANON U MIGHT BE ON TO SOMETHING...

being a researcher and having 2 eel mers in captivity...it's so rare for two of them to be in the same area without fighting each other to death- perhaps they're siblings? dna testing confirms it.

it's a rare opportunity for you to be able to study and compare the behaviors of eel mers- much less ones who came from the same clutch!! it's practically a boon of data; only a fool wouldn't take advantage of this.

at first, you just observe their behaviors with live food and stimuli. nothing interesting really comes out of it besides how the eels seem to look at you with a a mix of odd fascination and disdain. surely this isn't the extent of human knowledge...

eventually, you try sending a light electrical current through the water- nothing that should harm them, just a faint tickling sensation. that has their attention. are you intending to play with them, human? the one you named jade seems to be particularly interested, swimming up to where you stand, tapping a clawed hand at the glass that separates you. he doesn't seem discomforted. rather, he seems aroused. (although frankly, the mating rituals and mating of eel mers in general isn't well studied.) you brush it off as you anthropomorphizing the eel mer, and simply note a higher spike in activity from the eel mers following the currents.

yet no matter what you do afterwards- even feeding floyd his favorite live prey- nothing elicits the same reaction. surely this calls for a repeat of the prior experiment? this time, you raise the voltage ever so slightly.

the reaction is immediate. both eel mers begin to move in an odd sort of dance in their respective territories, their expressions fierce. after some time, floyd begins to claw at the the entrance of his favorite hiding spot. jade circles one of the coral decorations, rubbing against the rough surface so tightly that you see traces of blood dissipate in the water.

never has an event like this been recorded before. you can feel the scientific community clamoring over this breakthrough- the elusive eel mer's mating habits finally debunked after years of speculation....

you must find out more.

Voltages 3 New Titles for 2024

The japanese Version of Love 365 announced 3 new titles for this year. The first one will already release at the end of April.

You can watch the trailer here: https://youtu.be/Q8sn1uNZe-Q

My childhood friend - My second first love (Late April)

The title boy is called Kuroe Kento (黒江健斗). MC seems to be engaged at the start of the story however her fiance betrays her and it seems like she is seeking comfort in Kuroes arms. Her childhood friend has grown into a fine man.

The premise feels similar to My Last First Kiss, Love Brings You Home or maybe even Kings of Paradise.

Head over Heels Marriage - I'm too obsessed with my wife to let her go (June)

The title man's name is Mikoshiba Kazuma (御子柴和真). MC starts of happily married with her man, living their best life in his suite. However, things feels too perfect, is really truly everything okay?

I gotta say this title seems to be the most mysterious. The guy could be shady, or maybe does not have as much money as he deems or he is just overly smitten by his wife and does not give her much room to breath and pampers her rotten

From the premise it looks a bit like Oops I Said Yes or maybe even the untranslated Honey Moon title.

I could also imagine it to be a more wholesome or realistic Kissed by the Baddest Bidder without the auctions? Anyways the guy reminds me a bit of a mix of Kunihiro and Kazuomi (at least on the cover)

Kiss Me Until Daybreak (August)

The last of the three protagonists is called Iriyama Tsubaki (入山椿). MC is hopelessly in love with the man but he is not interested in a relationship. Luckily friends with benefits is rather popular these days so she might just be able to convince him in that way.

This title seems to be a bit more angsty and emotional compared to the others. It gives me Irresistible Mistakes and Hiroki from My Last First Kiss vibes. Und

Anyways this is whats to come in the near future.

My opinions under the cut

In my opinion the titles give a more mature vibe and feel a bit like soft versions of the adult site Otona / Koi100 More. (The More stories that we are currently getting are from the for example, though they have their exclusive titles too).

I have to admit none of the titles really caught my eyes right away and they feel more like Oneshots similar to Perfect Boyfriend or A World With(Out) You. They somehow lack the... glow? of other Voltage titles, but I'd gladly get proven wrong 😄 Currently i cannot see them having multiple seasons or even multiple characters? Plotwise i'm most curious about the Marriage title, artwose Kiss Until Daybreak even though I'm not that much of a fan of friends with benefits. The sprite of childhood friend looks good to me!

I feel like Voltage might be stalling for time until they can continue with Kings of Paradise or Tokyo Love Hustle.

I felt like instead of just relationship / romance focus I would have loved another supernatural or action series (which is why i really hope they'll continue TLH) because they feel similar to other titles. Voltage has proven that they are great with the supernatural themes with Court of Darkness or Even if Tempest, so i'm definitely excited about their new Switch titles. I just wish they gave a gem to Love 365 too haha.

Anyways let's wait and see.

[cornyonmains]

Going back and rewatching the first two episodes of 4 minutes, because I've been writing a lot of meta off the top of my head, and when I watch these shows, there's a lot I tend to notice and forget once an NC scene ensconces me into a horny brain fog.

A few minutes into episode 1 and it becomes apparent I completely glossed over this show's use of numerology, specifically angel numbers.

In numerology, angel numbers are believed to be numbers used by the spiritual universe to offer people insight and direction.

A lot of people have been noting the use of the number 11, which is an angel number, but what I overlooked at first glance, as did many others it seems, is the use of the number 200. With 200 being the number of joules the doctor at the beginning of episode 1 orders the defibrillator set to.

The number 200 is considered an angel number, one the universe sends to tell you you need more balance in your life, that one needs to take a step back and examine where they're headed. This number is also a sign that time is right for union with a twin flame.

Astrology.com has a good write-up on it:

I also think it's very telling that the doctor ordering that voltage is the one who originally tried to talk Tyme into becoming a teacher. He's also the reason I don't think it's Tyme on the bed. I think it's Great, having managed to switch places with Tyme, which is why we see the wounds in the same place. We're seeing the end result of Great succeeding in saving Tyme. I don't think that doctor would have been in the room if it was Tyme, because that would have been a conflict of interest. Also, I compared nipples. I'm like 90% sure it's Great.

It's also worth noting all the angel numbers we see in this show have 2 baked into them in some way, like 11 being 1 + 1 = 2. Or 200 being 2+0+0 = 2. This is important because in numerology these numbers mean union.

There's a pretty fascinating amount of new age spiritualism and fringe sciences going into the creation of this show. I mentioned in an earlier meta how the show's use of theme and color made Tyme and Great seem like black and white holes. Two characters in a state of thermal equilibrium, necessary to each other, but not sharing energy despite a permeable path to heat. The end resolution seems to be to get these two characters to follow that heat path and become gray, which is another color used quite often. And the show is using the concept of time asymmetry, which exists within black/white holes to achieve this. It's worth noting in numerology that the angel number 200 instructs one to trust the path they're on. Everything happening to Great is putting him on a collision course with Tyme much faster than it would have happened in the original timeline.

Now, if anyone thinks this sounds like a lot of overthought hokum, I'd also note that NDEs have been documented as causing electromagnetic weirdness with people who experience them. And I'm fairly certain the time asymmetry the show is using, if scientifically accurate, would definitely result in electromagnetic interference as electromagnetics play a pretty big role in general relativity. I'd break down the relationship, but I'd have to read for like 15 minutes, and I already did that once for the numerology stuff. It's been stream of consciousness since then.

Anyways, back to the smut. Will drop more meta as it comes.
