A Greener Byte: The Dawn of Superconducting Computing

Once upon a time, in our not-so-distant future, our world became increasingly connected, increasingly digital. The machines we’ve built to store our data, solve complex equations, and connect us to each other are like the city that never sleeps—data centers, supercomputers, always humming, always working. Yet, every city has its cost. And for our digital city, the price is high, paid in the…

Tbh Idk how to explain this but I feel like my self destructive tendencies dont count as self harm since they don't involve cutting (too much of a fucking pushover for that) and don't /can't leave scars, instead they mainly involve punching myself, kinda trying to strangle myself, bashing my head against hard materials like walls , biting myself etc. Everything you ever see about self harm is cuts with sharp objects that leave many scars. Im starting to wonder if my experiences don't count since they're probably less intense

You know, sometimes I’m grateful that my first summer in my graduate lab, at the impressionable age of 22, my main assignment was to design and build a full closed-loop water cooling system, with a chiller whose heat exchanger had to also be connected to the building cold water system (which, if you screwed it up, had enough water flow that you could flood the whole lab). And I gained familiarity with all the main types of hose, tube, and pipe connectors and how to install them.

I also learned the very important life lesson of, if all else fails, a blow torch can solve nearly any problem. I think I solved three different problems with a blow torch that summer.

No home plumbing I might undertake will match the disasters I ran into that summer.

When we were kids, we didn't have access to cool power tools. Every summer, when the soapbox derby race was coming, we'd break into my neighbour's garage while he was at work. Then, we'd use his drill press, lathe, table saw, all the fun tools. Over the course of a week, a race car was produced, which is more than the workshop ever made during the rest of the year.

Sure, we could have asked him if we could have borrowed his tools, but no doubt he would want to be there to supervise. And then he'd want to help. We'd never get done while we were busy indulging the suburb-tinged fantasies of someone who didn't take wood shop and chose instead to idly worship at the altar of Television Presents: The Fantasy of Bob Vila in adulthood.

One year, Old Man Garrett got a security system. Probably this was because Ted (fucking Ted) didn't clean up the sawdust that one time like we asked him to. The old man must have seen the footprint, and realized that he did not wear size-seven Nikes. Child thieves, casing his precious table saw! Now, our humble breaking-and-entering had become significantly more difficult than "reach a coat hanger under the door and pull the emergency release."

With the help of some of the high-school kids who were taking electronics class, we managed to defeat the security system. We did so using an ancient Japanese technique known as "distract Old Man Garrett while he's setting it, and then cut the wires to the panel." I think it loses something in translation, but you get the gist of it. That year's car was especially sweet.

In adulthood, I got drunk and bragged to some work buddies about our little scam. They responded in abject horror, because I was still occupying the weird hump in the middle of a normal distribution of "acceptable crimes." It was terrifying to them to see one of their own, one of the suburbanites, speak openly about largely-harmless property crimes. What if we had been hurt, they shrieked. Around the water cooler, I would become a pariah, unless I could make amends.

I did hunt down Old Man Garrett after that, still feeling the sting of rejection. He was still on the property, and he still had a beautiful collection of immaculate cabinet-making tools in the garage. I rang his doorbell and, when he answered, I told him the whole story. He laughed.

"I knew it was you dumb shits from the beginning," he bragged. "Fucking Ted -"

"Fucking Ted," I echoed, unconsciously.

"Fucking Ted left his library book on building race cars behind on the workbench that first year. You didn't let him drive, did you?"

I shook my head. "We ran the car into him if the hockey-stick brakes ever failed."

We had a good laugh about the whole thing that evening, and I returned to work with my soul cleansed. It's just a pity Ted didn't know how bad he actually was at crime, before he tried to knock over that liquor store and all.

A Workshop for Creating Magical/ Fictional Crystals: A Guide from a Geologist

Hi folks, its me, here to talk about fictional writing again! Today I'm just tackling the idea of magical stones/mana stones by looking at existing minerals today and some neat properties that they have, and how you can apply these things to a fictional world. The goal is mainly to help you if you are stuck trying to come up with a unique magic system, or a unique identification/characteristic of your mineral.

First Things First: Mineral Shapes

I am exhausted, petered out, down-right fatigued by seeing every mineral depicted with having the crystal structure of calcite and quartz. There are soooooo many cooler, more interesting crystal structures, don't you think you would stop and take a look at a perfect cube in nature? It is completely unsettling.

Second: Color

Color within minerals can either be really important, or not important at all! It is your choice to decide if color is going to be something that means something to your mineral. But what are some times when the color is important? Well.... there are some elements that are called chromophores, this classification just indicates that these elements, when present, will determine the color of whatever they are in. So, if you wanted to treat mana like a chromophore, you could say, "Oh everything that contains mana turns green!" This could mean that regardless of the mineral, if that mineral is a specific color, it means it contains mana. This concept is exciting because you can just stop here and use minerals that already exist! You can also use it as an indicator for a magical ore! Chromophores are typically metals, so if you are making a new metal weapon, making the ore of that metal a unique color would make a lot of sense!

However, your mineral can also just be every color of the rainbow like quartz and perhaps that's what makes identifying your mana stones elusive and create an illusion of scarcity that your character can solve.

There are other things that can change the colors of minerals, like radiation damage, and electron exchange, but I think that is beyond what would be helpful! So lets talk about some unique color properties that happen in nature that seem magical in the first place! Maybe you don't need to design a mana stone, but you want a unique gemstone that only the royal family passes down or something (IDK).

The first one is the alexandrite effect! This is where a mineral can change color in natural light vs. incandescent light. (the mineral itself is not changing, but the lights contain different amounts of different colors that then get absorbed by the stone). Even if you don't use electricity in your fictional world, you could have the colors change in the presence of light magic. This could create fun misunderstandings about what the mineral is reacting to!

Pleochroism

Pleochroism is something that most minerals have, it is frequently used to help identify minerals in thin sections, however minerals are usually not pleochroic enough for it to be visible to the naked eye! Pleochroism is just a fancy name to describe the change in how light is absorbed based on the angle of the mineral! So if you scroll up to the first image where I showed a lot of crystal shapes, most of them have angles where they are longer and shorter! This will effect the way light travels in the crystal. Tanzanite is a popular mineral that does this.

Photochromism

This is when a mineral will change color (in a reversible way) when exposed to UV light (or sunlight), I am not going to go too into the details of why this is happening because it would require me to read some research papers and I just don't feel like it. The mineral that is best known for this is Hackmanite!

Alright! These are all the really cool color effects that might inspire you or maybe not, but now I am going to talk about how you might find your minerals within a rock!

When I see a lot of magical caves/mines, typically I see them with some variation of a geode honestly, but most minerals are not found like that! Now I am sure most of you guys have seen a geode, so I will not really talk about those, but I will talk briefly about porphyroblasts which is when the mineral grows larger than the minerals around it, this happens in metamorphic minerals!

sorry random stranger, but this is an image of garnets inside a finer-grained rock at gore mountain in New York!

Another way you might find minerals is in a pegmatite! This is when all minerals are really large! This is a formed from really slow crystalizing magma!

But something else to think about is that your mineral might just be massive, it doesn't have to have distinct crystals, it may be similar to jadeite where small grains grow together which leaves it looking smooth and seamless! A note about all of these is that you would have to mine into the rock to find these, there would not be any natural caves in these rocks! Caves are only ever really formed in limestones and maybe marbles (rocks that react with acid).

How can your characters identify these minerals?

Typically when you are out in the field you will look to see what type of rocks the minerals are found in (The overall texture of the rock will tell you how it formed). If you know how the rock formed, it will narrow down the amount of minerals you need to think about by quite a bit! Next, you are going to look closely at it and observe its crystal structure, does it have an obvious crystal? if so what is the general shape? If it is broken, how did it break? Did it fracture like glass or did it break along uniform planes. Some minerals have a thing called cleavage (breaks along planes of weakness). If a mineral exhibits this habit, it will again help narrow this down. Next we can look at color. Color can be misleading, because minerals like quartz can be any color imaginable, but minerals like olivine will always be green! The next thing your character can do is test for hardness, minerals all have a specific hardness that can help identify it as well.

After you go through all of this, your mineral might have some special property! This could be magnetism, fluorescence, reactions to acid, or any of the color changing effects I mentioned above! Other than that, your character can take it back to a lab and do a number of things to identify it, but the most typical thing would be for them to make a thin section (very thin piece of the rock) and observe it under a cross polarized microscope!

On that note folks! I hope this helped in some way in thinking of new magic mineral properties! I have other guides that explore some different fictional worldbuilding issues you might run into, but if you have any topics you would like me to cover please that I haven't mentioned already, let me know!

The Van Has Officially Declared It Spooky Season

---

I've got my parent's van for the week and it seems determined to establish my status as The Local Cryptid by terrorizing an innocent 7-11 clerk.

...I might need to back up a bit.

My mother is an eminently sensible woman who knows herself well, and when The Plauge hit, she knew she'd need some sort of mentally and physically engaging craft project to keep herself from going insane and massacring the local zoning and water management boards (even if they have it coming). So she and Dad acquired a utility van and converted it into a camper van because while they love camping, they're past the age where their joints and immune systems will tolerate sleeping on the cold ground in a nylon tent.

They did a terrific job of it and my mom taught herself woodworking and carpentry and now the van has it's own cabinets, fold-away dining table, and removable queen-sized bed with memory foam mattress. My Dad was already a computer engineer, but he learned the dark magics of automotive software and electronics to install after-market backup cameras, a media player that would take a terabyte hard drive and a solar-powered battery and outlet so they could wake up and just turn on the kettle and griddle for breakfast without having to exit the van into a cold morning on an empty stomach.

Truly, the height of Camping Luxury.

My parents are both in their mid-seventies and my primary life goal is to be at least half as cool and hale as they are when I get old.

Anyway, they take it out at least a dozen times a year and it works fabulously, but, being as I am on good terms with my parents and also finishing the process of moving house, I've been borrowing it to move large and cumbersome objects that will not fit in the back of my equally lovely but minuscule Honda hatchback.

It's a Great Van. Very easy and comfortable to drive. Stunningly good MPG for it's size. The best cruise control I've ever had in a car.

It's just also. Quirky. Mischievous, even.

---

If this van has a fault its that it bears the unfortunate affliction that all lightly used white utility vans have in that the combination of an utter lack of branding features and the large dent/scrape I accidentally put on it while trying to escape a Denny's last Thanksgiving means that this vehicle is one addition of a Badly Spray-Painted "FREE CANDY" on the side away from being the sort of vehicle you see in an edgy horror movie.

It's got the same issue that Doberman Dogs have where they look like the sort of creature that likes to snack on toddler's faces whilst actually having personalities made of marshmallow fluff. This vehicle is unnecessarily menacing and I think nothing short of an airbrushed Epic Van Wizard will correct this. People see this van pull up and lean over and squint suspiciously at me when the driver's side door opens, and then look moderately confused when, instead of Charles Manson, a small, potato-shaped creature with neon purple hair and a statistically unlikely assortment of dogs emerges.

My own two dogs, Herschel the Hanukkah Goblin/Corgi and Charleston Chew The Taco Dumpster Dog, Do Not Like The Van. Even with the bed in it, they have a tendency to slide and roll around in the back, and both WILL chew through dog saftey belts or other attempts to secure them in there.

On the other hand, my house mate's dog, an exceptionally tall standard poodle whom we lovingly call "The Creature", loves the Van because SHE wears her doggy seat-belt with only mild complaining and gets to sit up in the passenger seat like A People.

Also like A People, The Creature likes to stand and walk around on her hind legs. It doesn't hurt her and it's entirely voluntary, but every so often I will feel a hand on my arm and instead of my husband or friend, it's a canine that's taller than I am on her hind legs who wants to stare at my face with soulful, concerned eyes. The Creature's favorite thing is that she is exactly the right height for me to hold her arm in Genteel Fashion and walk around the pet food or hardware store with her like I'm a count escorting a debutante around a royal ball.

---

As it stands, I am set to inherit this vehicle whenever my Honda gives up the ghost, and I fully intend to paint an Epic Van Wizard on it when that time comes.

The other peculiarity of The Van is that while Dad did manage to successfully install all his after-market electronics, not all the electronics get along. Sometimes, they fight for Dominance. The Terabyte Music Player and the Backup Camera have a particularly contentious relationship, and turning on the music has about a 25% chance of turning on the backup camera as well, and turning on the Backup Camera is equally likely to turn on the music.

Firthermore, The Van has a favorite song.

I am not kidding that Dad filled an entire terabyte hard drive with music and the software to sort it via the radio controls, but of all the Early Boomer Dad Rock (Kingston Trio over The Eagles) and Irish Folk and Symphonies and the entire discography of Weird Al Yankovic, The Van's favorite song- The one it picks to play as victory music every time it beats the Backup Camera at their weird electronic game of rock-paper-scissors -is The Liberty Bell March by John Phillip Sousa.

You all know this song already.

...but in case you've forgotten the tune:

Yeah.

The Van's favorite song is the goddamn Monty Python's Flying Circus Theme Music.

It does not play this song at a normal volume.

Every time I turn on the Backup Camera and it manages to turn the music player on as well, The Van insists on absolutely blasting this nonsense on at the maximum volume it's physically capable of producing, which I know is loud enough to be heard from the Denver International Airport's Pickup zone when they Van decided to start playing it from the economy lot about half a mile away.

Perhaps it's The Van's way of honoring the aesthetic sensibilities and sonic enthusiasm of Mr. Sousa.

...I can't help but wonder if the purpose of an Epic Van Wizard is to control this sort of faerie-like malarkey, and channel these chaotic energies into things like Spell of Don't Break Down In Nevada or Enchantment Of Always Have Good Parking.

So last Friday the 13th, I get a call from my friend and housemate, at said airport.

It's roughly 11PM at night, and I have already retired for the evening. I am in the exact minimum of clothing required to be a decent housemate and not scandalize the neighbors should I happen to walk by a window. My feet are up. There is a cat in my lap and fictional British people murdering each other in highly inventive fashion on the tv. -But my friend has returned from her friend's wedding,and either American or United Airlines has managed to lose her luggage, including, among other valuable possessions, the keys to her car. ...So she cannot just drive home as originally planned.

There are, as luck would have it, her spare set of keys not eight feet from me.

Being a good and decent person, I agree to bring the spare keys to her so she may get home before daybreak and not spend a semester's worth of tuition on an uber across the greater Denver traffic jam.

Being also that she Loves Activities, and it's her mom we're going to pick up, I elect to take along The Creature.

I am primarily focused on remembering how to get to the airport and not leaving my friend's spare keys on the counter, so I throw on a pair of flip-flops, step outside, remember that it's AUTUMN and my minimal evening attire is not sufficient thermal protection, step back in, grab the first coat in the closet I lay hands on, pull it on, check that I have her keys again and leave.

The trip to the airport is largely unremarkable, save that it becomes necessary for me to put on sunglasses to drive, despite it being nearly the witching hour and almost entirely darker than the inside of a cow.

It's necessary because this blissful darkness of night is violently punctured by a startling number of cars that seem to have installed miniaturized but no less powerful lighthouse bulbs in where their headlights ought to go so the oncoming traffic and sports cars that insist on tailgating me in the slow lane alike illuminate the road and my mirrors with the kind of radiance I'd normally associate with the arrival of a Seraphim.

I arrive at the distant highly discounted airport car lot where my housemate is waiting, deeply apologetic. It's nothing. I say. Once I see that your car starts up, I'm gonna go to that 7-11 across the way that I parked in front of, get a slurpee or something and I'll see you at home.

While she is retrieving her vehicle (an equally eccentric but much more stately Subaru that is old enough to be elected to congress) I rifle through the loose change in the glove box and discover that I have exactly $6.66 in small bills and coins. The Subaru, continuing it's long voyage into vehicular immortality, immediately starts up.

Upon her return, we all remember that my friend had all her camping gear in the backseat of the car and there is no room for The Creature to ride home with her parent, so I again assure her it's nothing, and will just take The Creature into the 7-11 with me. She is trained as a service animal and needs the practice after the plague.

I wave my friend off and turn to enter the 7-11.

I promptly trip over the jutting back bumper of The Van and fall, cartoonishly, face-first onto the sidewalk.

Fortunately, I have a lot of practice falling on my face, and have learned not to throw my hands out but instead cover my face, so my unexpected self-inflicted attempted curb-stomping lightly scrapes my hairline and nothing else -my sunglasses even stay in place- and I get up and resume my quest for a slurpee.

It's well known that the airport is a lawless place, and the 7-11 across from the discounted airport parking at the stroke of midnight is no exception.

I know it's the stroke of Midnight because there's one of those Audubon society bird-call clocks that makes bird noises, and my arrival is heralded by the twittering call of a Summer Tanager. I am almost charmed enough by the unusual choice of chronological device to excuse the exorbitant Airport-adjacent mark-up of Slurpee prices. I stand at the machine for some time, trying to decide on a size for the price and guess what the fuck "Blue Lighting Blast" is supposed to taste like.

The Creature is being Very Polite but is somewhat agitated, I assume because she *just* saw her mother for the first time in three days and then she LEFT with no explanation, so The Creature is on her hind legs, staring woefully into my eyes, asking to be escorted around the 7-11. Even though that's not what she's not supposed to be doing, there's nobody else in here, so I let her hang off my arm and discuss various Slurpee Flavor options with her.

We eventually decide on an experiment in which I try a Small Blue Lightning Blast, and discover it tastes a bit like licking a nintendo cartridge but in a pleasantly satisfying way.

I go up to pay and realize something is amiss.

The Cashier is a young man staring at me with wide eyes, one had over the register and the other wrapped up in his rosary.

I look down at myself.

In my haste to reunite my friend with her spare keys and service animal, I had left the house in the following accoutrements:

Flip Flops. Not matching. It's below freezing outside. That last part is not particularly odd footwear for the weather in for Colorado, but it's an important detail for the rest of the ensemble.

Assorted scrapes, bruises, cuts and welts on my arms and legs that come with doing outdoor work and living in a house with three dogs and a fully-clawed cat that all want to be in my lap all the time. It's cold out, so vasoconstriction has pulled the blood away from my skin, a trait that served my ancestors well during the last Ice Age, but leaves me with pale skin to contrast the various wounds and I look like a corpse that fell out of the back of a pickup truck.

The black Bootyshorts with "CRYPTID" painted in bright red gothic font across my ass, that @theshitpostcalligrapher gave me for my wedding present.

A peculiar but extremely comfortable garment that straddles the line between "Lacy Camisole" and "Industrial-Strength Sports Bra" like the Ever Given straddling the Suez Canal. It is also Bright Red. with black accents.

The Jacket I had grabbed out of the closet, which is in fact, a black Velour Dinner Jacket.

The Tokyo-Ghoul inspired reusable anti-covid mask a friend made me with the set of Coyote Teeth.

My sunglasses, which are shaped like a Halloween Bat. The lenses are the wings and the body is the nose bridge. It is ALSO bright red.

A Very Large and remarkably Humanoid Poodle that I have been audibly affectionately calling "Dear Creature" who is hanging off my arm like she's my Prom Date.

The Very Large and remarkably Humanoid Poodle is ALSO dressed up in a black Dog Sweater that has white bones printed on it to look like its an X-ray jacket showing off her skeleton.

I look like I am taking my Very Fancy Werewolf Girlfriend to a particularly casual Dinner Party for Vampires, but the thing that's really selling it and probably alarming the kid the most is the fun accessory I acquired in the parking lot not five minutes earlier:

The "Small Scrape At my Hairline" is actually a painless but PROFUSELY bleeding head wound that I had somehow entirely failed to notice covering my face, neck, decolletage and magnificent cleavage with blood like a Tarantino Film Extra.

This does explain why The Creature has been delicately trying to use her bodyweight to push me down onto the floor for the last ten minutes. So I don't injure myself while we wait for the paramedics she hoped this kid called to arrive, you see.

The Creature has such a High and Naive Opinion of humanity.

I decide this social situation is already fucked, and the only way out is through, and with haste, before I start dripping on the floor.

"Hi there!" I say cheerfully, to indicate this is a visually alarming but not terribly serious situation. "Just a Small Slurpee!"

The Cashier has entered the relevant code into the register before I finish the sentence. His gaze flicks off me just long enough to look at the total, and he grips his Rosary harder.

$6.66

"Oh cool! I have exact change!" I say, taking the money out of my as-yet-unsanguined pocket without looking and slap it down on the counter. "You have a good night and be safe out there!" I wave, leaving.

I get in The Van, mortified, buckle The Creature up, and as I make to leave, I have to put it in reverse, which automatically turns on the backup Camera.

It also turns on the music player.

I make eye contact with the cashier as the dulcet tones of John Phillip Sousa boom from the van hard enough to make the windshield and the windows of the 7-11 rattle for the nine-and-a-half seconds I have to wait to be able to turn the volume back down. Not knowing what else to to, I give him a thumbs up, and leave.

Anyway, now I know what my Future Van Wizard has got to be dressed like, and what their familiar is.

This has probably been requested before, but I had this idea and wanted to share.

My personal headcanon is that Vox keeps his room super cold to help with all the electronics (I took an animation class and that room was always freezing!). So, reader naturally has a blanket hoard that they bury in like a dragon buries itself in treasure.

Not sure if this was something you wanted to write about, but wanted to share regardless!

BRO YOU HAVE NO IDEA HOW MUCH THIS IDEA BRINGS ME JOY! YES! I saw a request the other day about the idea of Vox having his aquarium connected to his bedroom and I haven't been able to get it out of my head. Also, it drives me insane we only have the name for one of his sharks. In a high stroke of genius, I've decided the other shark is named Spark. Vark and Spark. This is my canon now, amazon be damned.

Cool Temperatures [Vox x Reader Headcanons NSFW Mentioned]

(NSFW writing under the cut. Minors stay away <3)

Vox was never one to get too cold. In fact, if anything, the infernal blazes of Hell proved to be a nuisance when it came to day-to-day life for the overlord. To combat this, Vox's room had every state-of-the-art cooling system known to every ring of Hell. A solid 27% of the electricity bill for the tower was consumed by the air conditioners and the aquarium from the meeting room that connected to his room above.

You need every blanket and hoodie in the Pride Ring to stay warm in his room. It was large, it was dark, and it was fucking cold. When you went into his room for the first time, it had been on your third date. You'd both gotten a little tipsy and were eagerly pulling each other's clothes off when the large double doors (dude is bougie as fuck) slid open when you were nearly knocked over with what felt like the fucking tundra.

Of course, Vox teased you with a shit-eating grin as he watched you shiver. You'd tried to complain about the ridiculous temperature as you attempted to pull your shirt back on, but Vox's hands were on your wrists in an instant. The way your body reacted to the cold was one of his new favorite things. He relished in the way goosebumps decorated your skin and he wasted no time in showing you just how much he appreciated how the cold affected your tits.

It didn't take as much convincing as he expected when he asked you to move in with him. Only after a few months of dating, he was already determined to spend the rest of eternity with you. He expected you to protest due to how many times you woke up in the middle of the night freezing cold because Vox kicked all the covers off in his sleep. He expected you to hesitate because of how much you hated getting out of bed due to the cold. But instead, you said yes immediately.

"Yeah, waking up in the morning sucks," you admit as he questions your willingness. "But on the mornings you haven't left early for work, it's worth it because you're there."

Vox was so unbelievably whipped from that day on. He went to the development team and had them make you a giant heated bean bag that you used obsessively. He'd lost track of the number of times he'd come home late after a long day at work, only to find you wrapped up in a dozen blankets and in your favorite hoodie, all cozied up on the shark patterned heat.

Sometimes you have to kick his ass for stealing your hoodies. He didn't need them! You needed them! You were going to turn into a popsicle, meanwhile a refrigerator might as well have given birth to your silly boyfriend. He just liked making you try to take it off of him. And he liked that it smelled like you.

"Heat stored underground in caverns can be set aside in Finland’s summer months to be re-used during frigid winters thanks to a state-of-the-art ‘seasonal energy’ storage facility.

Slated for construction this summer near Helsinki, it will be the largest in the world by all standards and contain enough thermal energy to heat a medium-sized city all winter.

Thermal exchange heating systems, like those built underground, or domestic heat pumps, are seen as the most effective way available of reducing the climate-impact of home heating and cooling.

Their function relies on natural forces or energy recycling to cool down or heat up water and then using it to radiate hot or cold energy into a dwelling.

In Vantaa, Finland’s fourth largest city neighboring the capital of Helsinki, the ambitious Varanto seasonal energy storage project plans to store cheap and environmental friendly waste heat from datacenters, cooling processes, and waste-to-energy assets in underground caverns where it can be used to heat buildings via the district heating network whenever it is needed.

In Finland and other Nordic countries, the heat consumption varies significantly between seasons. Heat consumption in the summertime is only about one-tenth of the peak load consumption during the cold winter months.

Varanto will utilize underground caverns equal in space to two Maddison Square Gardens—over a million cubic meters—filled with water heated by this waste heat and pressure that will allow the water to reach temperatures of up to 300 degrees Fahrenheit without the water boiling or evaporating.

“The world is undergoing a huge energy transition. Wind and solar power have become vital technologies in the transition from fossil fuels to clean energy,” says Vantaa Energy CEO Jukka Toivonen.

“The biggest challenge of the energy transition so far has been the inability to store these intermittent forms of energy for later use. Unfortunately, small-scale storage solutions, such as batteries or accumulators, are not sufficient; large, industrial-scale storage solutions are needed. Varanto is an excellent example of this, and we are happy to set an example for the rest of the world.” ...

“Two 60-MW electric boilers will be built in conjunction with Varanto,” adds Toivonen. “These boilers will be used to produce heat from renewable electricity when electricity is abundant and cheap. Our heat-producing system will work like a hybrid car: alternating between electricity and other forms of production, depending on what is most advantageous and efficient at the time.”

... Construction of the storage facility’s entrance is expected to start in summer 2024, while it could be operational as early as 2028."

I wish i could stop rapidly fluctuating between being completely fine mentally, legitimately wanting to die, and being so afraid of death that I freeze and stop what I'm doing immediately for a second or two

[probablyasocialecologist]

The flotsam and jetsam of our digital queries and transactions, the flurry of electrons flitting about, warm the medium of air. Heat is the waste product of computation, and if left unchecked, it becomes a foil to the workings of digital civilization. Heat must therefore be relentlessly abated to keep the engine of the digital thrumming in a constant state, 24 hours a day, every day. To quell this thermodynamic threat, data centers overwhelmingly rely on air conditioning, a mechanical process that refrigerates the gaseous medium of air, so that it can displace or lift perilous heat away from computers. Today, power-hungry computer room air conditioners (CRACs) or computer room air handlers (CRAHs) are staples of even the most advanced data centers. In North America, most data centers draw power from “dirty” electricity grids, especially in Virginia’s “data center alley,” the site of 70 percent of the world’s internet traffic in 2019. To cool, the Cloud burns carbon, what Jeffrey Moro calls an “elemental irony.” In most data centers today, cooling accounts for greater than 40 percent of electricity usage.

The Cloud now has a greater carbon footprint than the airline industry. A single data center can consume the equivalent electricity of 50,000 homes. At 200 terawatt hours (TWh) annually, data centers collectively devour more energy than some nation-states. Today, the electricity utilized by data centers accounts for 0.3 percent of overall carbon emissions, and if we extend our accounting to include networked devices like laptops, smartphones, and tablets, the total shifts to 2 percent of global carbon emissions. Why so much energy? Beyond cooling, the energy requirements of data centers are vast. To meet the pledge to customers that their data and cloud services will be available anytime, anywhere, data centers are designed to be hyper-redundant: If one system fails, another is ready to take its place at a moment’s notice, to prevent a disruption in user experiences. Like Tom’s air conditioners idling in a low-power state, ready to rev up when things get too hot, the data center is a Russian doll of redundancies: redundant power systems like diesel generators, redundant servers ready to take over computational processes should others become unexpectedly unavailable, and so forth. In some cases, only 6 to 12 percent of energy consumed is devoted to active computational processes. The remainder is allocated to cooling and maintaining chains upon chains of redundant fail-safes to prevent costly downtime.
