I dont mean to throw shade on fusion, but just wanted to point out that even if they get to "net positive", they're still not going to be making electricity with it. The best steam turbines are only about 35% efficient, so even if your power plant produces 105% of the energy you put into it, you're only getting (at most) 35% of the 5% output. Yeah it's "free energy", which is cool, but you'd only get 1.75% of the total capacity of your power plant(!) in profit, not counting other losses/costs such as cooling the magnets or the myriad other costs to run the thing.
I dont know the number, so I'll guess you'd need to get to 150% or higher to rival even a small conventional power plant.
