So what is this made of if not lithium?
Carbon. Much cheaper, and basically, infinitely abundant. Big big big deal if they can scale it.
That always seems to be the rub. You can make these breakthroughs in a lab, but if they can't be translated to manufacturing, then it's not a huge achievement.
What's the round trip energy efficiency?
I didn't read anything beyond the summary
From the linked article
Chatgpt says:
Don't use chatgpt as a source, there is no reason to trust anything it says.
It might be right, it might have just thrown together words that sound right, or maybe it's completely made up.
it just guesses the next probable word. literally everything it says is made up.
Words are how we communicate knowledge so sometimes the most probable combinations of words end up being facts
while it's technically true that it "just predicts the next word", it's a very misleading argument to make.
Computers are also "just some basic logic gates" and yet we can do complex stuff with them.
Complex behaviour can result from simple things.
Not defending the bullshit that LLMs generate, just to point out that you have to be careful with your arguments
“ChatGPT, please provide your rebuttal to this statement about you: […]”
You have just described how human brains work
right, and they're actually pretty bad at remembering facts, that's why we have entire institutions dedicated to maintain accurate reference material!
why do people throw all of this out the window for advice from a dumb program I'll never understand
Not really. We also have deductive capabilities (aka "system 2") that enable us to ensure some level of proof over our statements.
What is the energy density (by volume) of this? It sounds like a rebrand of a hydrogen fuel cell, which has some limited applications, but has been supplanted by lithium-ion due to hydrogen’s low energy density and the fuel cell/electrolysis combo having poor energy efficiency.
Edit: specified density by volume, as density by weight was never the issue
Irrelevant to this discussion, though.
How does it compare to competing technologies?
And more pertinent, how small does it get? Fit one in my phone? Motorcycle? Car? Boat?
You asked for the energy density, that's why it's relevant?
For the rest of your questions, try Google?
