JET's final nuclear fusion experiment produced a record-breaking 69 megajoules of heat. Nice.

    Tokamaks… sigh.

    When it finally works, you will have invented the most expensive form of energy we’ve ever imagined. Congratulations.

    I mean, don’t get me wrong, I’m excited for fusion. Fusion has some amazing potential as a power source and propulsion for space ships. But outside of that application, I don’t know… I’m pissemistic. I do not think it will be the global energy revolution so many people seem to think it will be. It will not be unlimited cheap energy, not be a longshot.

      its gonna be unlimited expensive energy, which is a start.

      except we needed a start 20 years ago, not now lol

        Is it unlimited though? I mean sure, the fuel is abundant, we have hydrogen. But the other support materials are quite limited, berillium, helium, nuclear engineers. I don’t think we have enough of all of that for an energy revolution.

        And if there’s one thing we’ve all learned, it’s that if it’s cheap to make, the trillionaire owners won’t overcharge for it.

        Yes, I think we’ll have trillionaires first.

      There are several other topologies with promise. But even a tokamak can use its first wall latent heat to turn the archaic steam turbine.

      While I also have low expectations for plasma density in tokamaks, they’re able to keep plasma at fusion temperatures for minutes at a time.
