This just means for every n W of _heat_ injected the fusion creates 10n W of heat. But I'm pretty sure the experiment itself consumes much more electricity than it could theoretically produce (don't forget that converting heat to electricity has an efficiency below 50%). Fusion researchers mislead the public to get more funding when they say ITER will make more energy than it requires. Fusion might be never viable.

Yeah well anything above a ratio of 1 would be beyond anything we have in terms of return based on investment in relation to cost to generate heat and it’s output. Basically all technology thus far is <1 right?

Q is just energy out over energy in. It is not an economic return.

Yeah but what else puts out more than puts in energy wise?

Any energy source that people actually use. And most of them have near-zero energy input during active use.

A 1000% return only just covers unavoidable inefficiencies.

No Tokamak will ever pay off its investment.

Right, that’s the ridiculousness of it.
