I believe that there might be a way to have a compact and efficient fusion reactor which we just don't know yet (and a time traveller would be able to "hold my beer" us into it)
For example, there's this plasma-producing microwave + cut grape trick, what if you use something like this to supply really hot deuterium plasma?
- jleahy 4y agoThen you get super hot deuterium plasma, which is unconfined and so won't fuse.
- thriftwy 4y agoMaybe you can generate it in one place and confine it in the other? Not dissimilar to how ICEs work. Produce plasma and then burn (fuse) it in pulses.
- willis936 4y agoThat's actually exactly what existing MCF machines do. The gyrotron (ECRH, same as a microwave's magnetron) resonant frequency is tuned to the confinement field strength of the plasma so it absorbs the energy. On top of that there's a vacuum so air doesn't pull all the heat away and a magnetic bottle so the plasma doesn't touch the wall. Fusion is very far away from happening spontaneously on Earth.
