    Meh, net gain is the point, long cycles well be useful for production. Useful, eventually. Cart before the horse, otherwise.

    Forget artificial suns, let me tell you right now how to make an artificial moon:

    1. Be a robot.
    2. Pull down pants.
    3. Bend over.
    4. Point robo-crack towards recipient
    5. Artificial Moon.

    While neat, this is not self-sustaining — it’s taking more energy to power it than you’re getting out of it. (You can build a fusion device on your garage if you’re so inclined, though obviously this is much neater than that!)

    One viewpoint is that we’ll never get clean energy from these devices, not because they won’t work, but because you get a lot of neutrons out of these devices. And what do we do with neutrons? We either bash them into lead and heat stuff up (boring and not a lot of energy), or we use them to breed fissile material, which is a lot more energetically favorable. So basically, the economically sound thing to do is to use your fusion reactor to power your relatively conventional fission reactor. Which is still way better than fossil fuels IMHO, so that’s something.

      Helion has an interesting take on fusion reactors that generate power using electro magnetism and Copenhagen Atomics are trying to create Thorium reactors. I hope they will work better than the boiling they use in tocamac reactors

      It seems like it’s probably too late.

      Even if we crack fusion power today, I can’t see it being deployed cheaply enough and quickly enough to compete with solar/wind+batteries. By the time we could get production fusion plants up and ready to feed power into the grid, it’d be 2050 and nobody would be interested in buying electricity from it.

      • Even in a world already powered 100% by renewables, fusion is attractive for high energy applications. For a current example see training of LLMs. However there are Industries with immense power requirements like Aluminium smelting that could use fusion power as well.

        So far humans have found applications for all energy they were able to produce.

        Long distance transmission creates enormous power wastage, and cities are rarely located in places ideal for large scale wind and solar. Fusion can help deliver power to urban centres, reducing the acreage needed for a solar farm.

        There are also inland places in northern latitudes that benefit little from solar. Wind and fusion would be a great energy mix for those places.

        I think if we figure out nuclear fusion there will be induced demand for energy, in applications that were previously infeasible: desalination via distillation instead of reverse osmosis, direct capture of CO2 from the atmosphere, large scale water transport, ice and snowmaking, indoor farming, synthesized organic compounds for things like carbon sequestration or fossil fuel replacement or even food, etc.

        Geoengineering might not be feasible today, but if energy becomes really cheap we might see something different.

        Fusion would provide orders of magnitude more power than solar. There’s a limit on how much we can practically get from solar, fusion would allow us to exceed that.

          Yeah, but there’s no prizes for producing way more power than we use. We’re not running out of space to put solar panels or batteries.

            ‘Too much power’ has never been an issue, and will likely not be an issue ever with solar. There are multitudes of technologies, especially in industry, that are currently impractical because they would consume too much energy.

      No need!

      The data gathered by EAST will support the development of other reactors, both in China and internationally. China is part of the International Thermonuclear Experimental Reactor (ITER) program, which involves dozens of countries, including the U.S., U.K. Japan, South Korea and Russia.

      im pretty sure almost unilaterally, every country would like the solution to near infinite energy regardless. its extremely vital if as a species, ever want to start a colony outside of earth.

      the only people against it would be those in the pocket of other forms of energy monetary wise.

        It should be a huge liability, but the US is a fucked up place. Even “blue” states are full of people at work voraciously politicizing everything, always thinking they are right about everything. These people are everywhere, they lack humility and critical thinking, and they are insufferable.

    IIUC the end goal, for any fusion reactor, is to heat up water and drive a steam turbine.

    Imagine you could drive a steam turbine at zero cost. What happens if just keeping that turbine running costs more in upkeep than e.g. solar panels do overall?

    Is there really much of an economic case for infinite energy on demand (and that is if fusion can be made to work in not just the base load case) if we have infinite energy at home already?

      Even if not a single residential property gets hooked up to a fusion generator, there will still be an economic case for fusion, especially as you move away from the equator. Industrial applications require an enormous amount of energy, and with solar power having a hard limit on the amount of energy you can get from a square meter, you’d have to have square miles of panels and batteries to keep one plant going.
