Here's a question - what if this facility (the NIF), or similar facilities planning to attempt a net gain of energy from fusion reactors, actually work? It will still take a long time to build reactors capable of feeding power into the national grid, but if it can be shown to work in principle, governments and private investors will literally pour money into these projects like there's no tomorrow... this wouold be great for fusion power, but what about "conventional" energy companies - oil, gas, coal producers etc.; solar power, renewables etc., or even regular nuclear power stations? These will obviously still be needed - perhaps for a long time to come, but if fusion can be shown to work and work well, then could it potentially trigger a collapse of existing energy companies as investors pull their money out of dying technologies and invest in the future instead?
