alright guys, what we've got from solar power is going to be lots of power that you can't store available at random ass times. So what are we going to see? We're looking for industrial processes that are

  • hilariously wasteful of energy
  • equipment is cheap
  • you can turn them off and on easily

I've only thought of two things here.

  • Splitting water without good catalysts, just paying the overpotential. Why buy an expensive electrolyzer containing platinum or iridium as a catalyst, when the catalyst is expensive and power is cheap? Especially since you'll only be able to run the electrolyzer a minotrity of the time, when generation is especially high, so it's just going to be sitting idle most of the time. So I'm thinking we're going to start seeing inefficient green hydrogen production
  • Desalination of water by distillation. Or if not that, "Mechanical-Vapor-Compression", which seems to be the method with the worst energy cost but advertised as having cheap units. Right now I think people usually use reverse osmosis, where you use pumps to push water through a membrane. It's the most energy efficient, but it's capital intensive... I think a lot of the cost is buying and maintaining the membranes? Idk. Whereas you can just boil it. The MVC method seems to use heat for evaporation somehow so maybe it's not that different.

I was trying to think of a data center angle, but chips are expensive, you don't want to turn the computers off at night. Maybe ice-based cooling? Freeze water when power is cheap? Or water-based cooling, since water has a high heat capacity so maybe it will stay cool between spikes in solar generation?

yeah, nevermind, they're not going to do this. I mean to some extent they are or already do (see for example ice storage air conditioning. But the way to make money off a few hours per day of low electricity price, without too much capital investment, is just to charge a battery. I was still of the mindset that battery prices couldn't keep going down because they were ultimately limited by the availability of lithium. No, there's plenty of lithium, and sodium batteries aren't as speculative as I thought, they're ready to go at scale.

quick suggestion

let me raise you an idea ive been keeping for years, just for this moment

The unholy trinity.

only the finest culinary experiences for my followers

is astounds me that each image seemed like the worst thing ever, but then the next image would top that, and now we have ascended to Lovecraftian levels of bad and I fear for the fabric of sanity and reality it may get worse the more this post grows. 

Please keep adding to this post.

is this anything?

Practice, and millions of dollars of research into how to best do the job quickly without the risk of the tires falling off.

Racing slicks don't need to be balanced after being put on the car, they're more expensive per tire than some consumer cars are in total, and you pay for quality.

They don't check to see whether the tires need replacement, they just have a schedule to do so based on millions of hours of data on tire wear.

The car's body is designed to allow for rapid and stable lifting in a very specific way, and is completely overhauled after every race to guarantee it will keep working this way.

The pit crews train over and over in any conditions where the race isn't automatically cancelled (hot, cold, etc), drilling until they can do their parts with the same coordinated grace as professional dancers, if not more.

And, importantly, once the cars' top speed can no longer go any higher for safety reasons, all the focus goes to maximizing the time spent at that maximum speed. The technology of "go fast" capped out in most racing leagues a while back, more speed becomes too dangerous for human drivers. So all the money that used to go into "go fast" now goes into "don't stop as much."

Look what they took from us 😭

I am drooling

This gets me more excited than anything smart refrigerators can offer. I want to learn refrigerator repair just so I can buy one and maintain it for all eternity.

"Judith Love Cohen, who helped create the Abort-Guidance System which rescued the Apollo 13 astronauts, went to work on the day she was in labor. She took a printout of a problem she was working on to the hospital. She called her boss and said she finished the problem and gave birth to actor Jack Black.

"Judith Love Cohen was, at various times in her fascinating life, an engineer who worked on the Pioneer, Apollo, and Hubble missions, an author & publisher of books about women in STEM and environmentalism in the 90s, a ballet dancer with the New York Metropolitan Opera Ballet Company, an advocate for better treatment of women in the workplace, and actor Jack Black's mother. From an obituary written by her son Neil Siegel after her death in 2016:

“'My mother usually considered her work on the Apollo program to be the highlight of her career. When disaster struck the Apollo 13 mission, it was the Abort-Guidance System that brought the astronauts home safely. Judy was there when the Apollo 13 astronauts paid a "thank you" [visit] to the TRW facility in Redondo Beach.'”

"She finished her engineering career running the systems engineering for the science ground facility of the Hubble Space Telescope.

"During her engineering career, she was a vigorous and tireless advocate of better treatment for women in the workplace. Many things that today we consider routine - the posting of job openings inside of a company so that anyone could apply, formal job descriptions for every position, and so forth - were her creations. She had a profound impact on equality in the workforce.

I love watching How It’s Made. Though I wish they would go one level deeper. They show all of these manufacturing processes with gigantic proprietary custom engineered machines that spit out 4 billion Cheetos at once. I want to see how those are made. I want to see a show called How They Make the Things That Make Things.

That is truly some of the most creative engineering I’ve ever seen. Like, my brother designs airplane wings for fighter jets. Which is cool… but wings haven’t changed much in decades. He’s kind of a… re-engineer. (Sorry, bro.)

Whereas a custom built machine that sharpens dozens of pencils at once must have had some interesting trial and error problem-solving. How did they settle on this design and what other designs did they try?

Or how did they make this ice cream sandwich masturbation mechanism. 

I want to see the messy test footage of ice cream going everywhere on the beta version. 

Who engineers these things? How are they built? How much do they cost? 

I might have to go on a YouTube hunt. 

To date, these might be my favorite replies to a joke I’ve made.

Op, I agree with you but please dont phrase it like that

Sorry about that… Joe Biden’s Big Naturals.
