Reply to comment by Holden_place in Is using the heat to produce steam really the best way to extract energy from fusion and fission? by Holden_place

I don't. But don't forget in both those examples the processes are very different.

A lot of the "waste energy" from gasoline will be in the form of thermal energy. Whereas in a nuclear reactor it's the thermal energy you want.

Understood. I was just using that as example as I learn about the fusion breakthrough.

I read that 300 megajoules power 2 megajoules of lasers. I am wondering how much more is lost on the back end.
