I think that we will reach net energy output within 30 years, with another 30 to actually scale that into a usable reactor, then another 30 to actually start using it widespread, and that’s assuming that costs continue to decrease on things like superconductors, and we get our tritium supply chain to exist. I’m a little biased as a student going into the field, but I’m hopeful.
This would be super interesting to see over many election years, stacking arrows might be tough but maybe a simple animation?
