    What do you think fusion research is?

      Just a fancier way to spin turbines with steam

        Fancier or more efficient?

        There’s a possibility of using the plasma directly for inducing electrical current, actually.

        But then yeah, probably steam with whatever’s left.

          now that would be revolutionary!

      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)

      Existing nuclear energy, too.

      No where near perfect mass conversion…

      Max theoretical mass-energy conversion efficiency is under 1%

        that’s still waaayyyy more efficient than coal

          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

            yes you can. coal costs ~32 cent per kWh, and uranium ~$0.0015 per kWh

              We were talking about the mass-energy conversion, for nuclear fusion.

              Not really sure how nuclear fission Vs coal cost/kWh is relevant.
