What do you think fusion research is?

[โ€“] sga@lemmings.world 1 points 4 hours ago

a fun fact: for the most efficient mass energy conversion, you need a huge spin black hole (preferably naked). Then you can get about 42% conversion. (there was a minute physics video about it i think)

No where near perfect mass conversion....

Max theoretical mass-energy conversion efficiency is under 1%

that's still waaayyyy more efficient than coal

[โ€“] absGeekNZ 1 points 10 minutes ago

That is a different level entirely.

The mass-energy conversion from chemical processes is extremely small compared to nuclear processes, you can't really compare the in any meaningful way

15 years away from a useful result

Just a fancier way to spin turbines with steam

Fancier or more efficient?
