nuclear power produces long-lived radioactive waste, which needs to be stored securely. Nuclear fuels, such as the element uranium (which needs to be mined), are finite, so the technology is not considered renewable. Renewable sources of energy, such as solar and wind power suffer from “intermittency”, meaning they do not consistently produce energy at all hours of the day.

fusion technologies have yet to produce sustained net energy output (more energy than is put in to run the reactor), let alone produce energy at the scale required to meet the growing demands of AI. Fusion will require many more technological developments before it can fulfil its promise of delivering power to the grid.

    They’re missing a fusion reactor capable of positive energy output?

          That’s the absolute worst analogy of wormholes as well. They don’t fold space, so stop folding the piece of paper.

              Explaining wormholes by folding a piece of paper is a bit like explaining tunnels by folding a piece of paper. It’s totally not what’s going on.

              They don’t fold spacetime, they don’t need to, they are shortcutting through spacetime via higher dimensions. Rather like tunneling through a hill rather than going over the top.

      It seems that today’s elites have made that Soviet transition from doing more to support their prestige to promising more to support their prestige.
