The Roof is on Fire
There’s also a thing called a thorium energy amplifier reactor which would be a lot more efficient. If it works as its Nobel prize-winning designers predict, known thorium reserves would run six billion people at American luxury for sixty thousand years.
Problem being, of course, that unless our devices all get a lot more efficient, that translates into a hell of a lot of waste heat which has to go somewhere. I think we need to invent a way to vent heat off into space. Maybe send it to the moon or something.
