Fission is only expensive because we’re depending on the free market to develop and deploy it.
Basically, we cannot depend on capitalism to fix a problem that capitalism created.
Well that’s just wrong. Capitalism makes things cheaper. Also fission has been built under communist countries so the point doesn’t make sense.
I’ve seen fairly credible estimates that say when we finally max out the usable land for solar and wind, we’d be producing 30-40% of the world’s electricity via those two methods.
That’s just bull crap. Even some back of the envelope calculations can prove that. Go look up some solar farms and wind farms. Calculate the power to area ratio then extrapolate.
You have a very wrong opinion of how capitalism work. Even way before Henry Ford economies of scale have been a thing. The fact is nuclear power large or small doesn’t make much money. Also profit maximisation is also cost minimisation, it’s two sides of the same coin. Again a country like China could mass produce small reactors even just for themselves, but do they? No they are mass producing solar and wind because it’s more economical. None of the arguments you have made in anyway stop China (who know how to build small reactors) wouldn’t do this.
