    Maglev could become more common and more effective, but a “no-limit” battery comes to mind (no resistance=infinite charge) which could make each city or nation own an endless reservoir of energy. Goes well with renewables.

    Those are just 2 ideas. I’m sure there will be a lot more.

    EDIT: ignore the “no limit” battery, that’s a mistake. I mixed resistance with charge and made a stupid and wrong statement.

      How does no resistance lead to infinite charge? I can see it having approximately infinite conductivity sure, but charge? how?

        Sorry, i confused the lack of energy loss from resistance to “charge”, so I’m wrong.

        It might be more relevant for semi conductors in order to save energy. Maybe railguns.

      I see your edit but in case you’re interested - a capacitor is technically a 0 resistance battery for DC.
