I've been meaning to check that out. There are actually a couple dozen fission startups. Fission is definitely an easier technical problem, but more difficult in other ways. Nobody minds if you fuse atoms, but you can't fission them without doing lots of up-front design and spending years getting through regulators. Some regulators are friendlier to new technology than others. Canada does pretty well, and has at leas…

When he says "you build it, power a building with it, and the government will come around," that's a good way to land in prison. A while back I was watching a presentation at a conference for reactor startups, which warned that the government doesn't play around and will prosecute anyone who fissions atoms without approval.
And to some extent that's justified. The downside of those rocks that heat themselves when you put them together is that if you're not really careful, they can heat up way more than you wanted. Powering a building isn't the hard part.
That said, the NRC is way too obstructionist. We could follow the lead of Canada and be a lot friendlier to new technology, without compromising on safety.
Regarding his fusion comments, of the 35 fusion startups there are a handful attempting advanced fuels that could generate electricity directly, instead of just producing heat. Helion for example will be attempting net electricity production in 2024, without a heat cycle.
