Sounds promising, but we need Wh/kg and W/kg numbers to see if the performance is any good.

going to war with a superpower is extremely bad
Russia isn’t ready a super power any more and Ukraine definitely didn’t have a choice on getting invaded.
I dread when the scammers will start using LLMs and voice models for their scamming. They could afford so many more calls.
Plus Cavin peeing has nothing to do with the author and isn’t legal since he’s never let Calvin and Hobbs be merchandised.
For some applications like spacecraft where weight is critical, it does make sense to use hydrogen fuel cells as a battery. But usually it doesn’t make sense.
Nice, I’ll take a look!
I’m surprised it’s only 10x. Running a prompt though a llm takes quite a bit of energy, so I guess even the regular searches take more energy than I thought.
Love covert cobal, great first hand research and analysis!
Plus you still need to launch a bunch of massive Saturn V rockets since so many people saw them launch. Unless they paid off everyone who said they were there? Building a moon rocket that doesn’t go to the moon isn’t that much cheaper than building one that does.
Need a decoy keyboard on the top deck to make the cat think they’re still getting in the way
Because NATO has never accepted applicants with active territorial disputes.
Was it fire fox it didn’t work on?
As opposed to a lot of super compressed gas to haul around? I didn’t think this super niche use case justifies a whole different technology.
Scuba tanks only go up to 5.5ksi. I think you’d need more like composite over wrapped pressure vessels (COPVs) for 10ksi. Those are relatively new even in spaceflight. SpaceX discovered some new physics when their AMOS-6 mission exploded on the launch pad in 2016 due to oxygen freezing inside the composite layers.
Here’s some more info on carbon fiber tanks vs COPVs https://www.reddit.com/r/SpaceXLounge/comments/taibc7/in_our_experience_copv_gainpain_flattens_out/
You could find it by coverting 70k ton CO2 into ppm and multiplying by climate sensitivity.
That depends on a lot more factors for how dilute it gets. I didn’t know how likely it is for the air currents to dilute the aluminum exhaust over a large enough area before it rains. Maybe someone could do some analysis, but I don’t know how.
Yeah batteries would probably work. A large battery bank can have 1kwh of capacity, and induction stoves are about 1.5kw. Which means you could run a stove for about 40min. You could bring more for longer. I’m sure by the time you can’t get propane, batteries will have gotten much better too.
But they can still sell hydrogen, they can’t really sell solar panels. Even encouraging people to keep burning things (like hydrogen) benefits gas since it slows down electric alternatives to gas heating.
If I’m reading figure 1b from the pre per review paper correctly, it looks like they might be very good. But I didn’t see any actual measurements in the paper.
