> in theory they'll be generating over 10x the amount of power that they're putting into it

Does this mean 9/10ths of the power can be sold and the other 1/10th can be re-used to power the reactor endlessly?

How much power does this produce compared to a nuclear reactor?

In theory, yes, but in practice it doesn't. But it does mean that they'll've proven the concept sound, and we can start making real fusion reactors.

That video's a bit confusing because it purely talks about watts and not everything is continuous.

Anyway, the important part: In addition to the output being thermal, with losses from conversion, only the energy going into the plasma is being counted. So measuring the entire system, this reactor might still be a little short of break-even.

So they arent counting magnets/magnetism as a source of energy like a battery then? However I'm sure these newer stronger possibly more directional/controllable batteries will have an effect in electric motors in the future.

I think the newer higher temperature super conductors helps, but then I wonder if the cooling facilities of the older generation of super conductors might have been a potential future safety feature on earth but not in space.
