Net-positive was achieved in 2013. As far as I can remember, ITER is a test-bed for economical and scalable nuclear fusion.
Also, the corporate world (at least here in Texas, of all places) is perfectly capable of rolling out state-scale renewable power (wind).
- kibwen 6y ago> Net-positive was achieved in 2013. Do you have a source for this? I was also under the impression that fusion has never yet produced a net of energy.

- lambdatronics 6y agoNope. JET achieved Q~0.7 in 1997[1],and that hasn't been beat since. In 1998, JT-60 would have gotten Q~1.2, had they put deuterium-tritium fuel [2] (but it wasn't built for that). You might be thinking of some news from NIF. In 2013, they sorta claimed to have reached ignition, but that was only by moving the goal-posts.[3] ITER is not by any means a test of an economical or scalable reactor -- it's still at the stage of a science experiment.
