I’m noticing in these comments that the tech bros that want to solve climate change by magical technological advances instead of using what we have had an interesting effect: some people on the other side have grown tired of the real technological advances that would actually help.
As far as I know, the current plans for fusion require deuterium and tritium. Whole deuterium can be easily obtained from water, tritium is a bigger problem. Its replacement, helium-3, is also not really frequent on earth.
I’m pretty sure the reason for that is that the sun is actually mostly not hot enough to do nuclear fusion, but has to instead rely on quantum tunnelling. This makes the fusion rate much, much lower. Now while this is good, because otherwise, the sun would burn up far too quickly and kill all of us, it also explains the low power, or energy per time.
