It doesn't scale or do 24/7 power like fission/fusion would. Not sure why everyone is still against nuclear but that's fine too. I certainly have nothing against solar or wind and think we need a mix.
And, honestly, my life would be way better if I could spend twice the energy I do now, without destroying the planet. Energy use is basically a synonym for quality of life for humans. If we can expand it without destroying the world, we should.
