    Default New superconducting magnet breaks magnetic field strength records

    New superconducting magnet breaks magnetic field strength records, paving the way for fusion energy:

    We've heard it all before but this looks promising:

    If we can make reliable fusion reactors economically then our future looks a lot brighter.

    I've been following the development of fusion reactors for 40 years and today, 9th September 2021, I feel slightly more optimistic than ever before.
    It's not the least charm of a theory that it is refutable. The hundred-times-refuted theory of "free will" owes its persistence to this charm alone; some one is always appearing who feels himself strong enough to refute it - Friedrich Nietzsche

    Same here, have you checked out Thorium reactors? They sound interesting. Trouble is same as fusion... developing it commercially. Once they make the breakthrough we are a lot better off.

    Current test fusion reactors take so much energy to run , I doubt they will get much excess energy back even when they crack it .
    They may simply be uneconomic .

    Thorium reactors were never originally developed because they cant produce the Plutonium needed for Nuke Bombs .
    Thorium Reactors do still produce dangerous nuclear waste , thats something many counties are trying to move away from .

    https://www.theguardian.com/environm...uclear-uranium
    "Thorium cannot in itself power a reactor; unlike natural uranium, it does not contain enough fissile material to initiate a nuclear chain reaction. As a result it must first be bombarded with neutrons to produce the highly radioactive isotope uranium-233 – 'so these are really U-233 reactors"
    "This isotope is more hazardous than the U-235 used in conventional reactors, he adds, because it produces U-232 as a side effect (half life: 160,000 years), on top of familiar fission by-products such as technetium-99 (half life: up to 300,000 years) and iodine-129 (half life: 15.7 million years).Add in actinides such as protactinium-231 (half life: 33,000 years) and it soon becomes apparent that thorium's superficial cleanliness will still depend on digging some pretty deep holes to bury the highly radioactive waste.
