I saw a lot of cautions about being cautious on this, and they were right.
It also emerged that US scientists had achieved "net energy gain in a fusion reaction" for the second time, the Financial Times reported. This adds significant heft to the case made by nuclear-energy advocates who say nuclear is nothing to be scared of and a good source of green energy.
As obnoxious as I find the anti-nuclear crowd, this is a terrible argument. First, the advance was not going to even potentially translate into a workable, commercial system for a long time to come. Second, this was an advance towards use of nuclear fusion for power generation. What the anti-nuclear crowd gets upset about is nuclear fission for power generation.
