    Persistant bistable switched superconducting sandwich with bacon or graphene or something...

    Nobody expected the switched state to persist after drive voltage was taken away. https://news.mit.edu/2023/study-superconductivity-switches-and-magic-angle-graphene-0130 So what, a memristor without resistance now, is that even allowed?

    Pulsed helium3 fusion in a magnetic bottle, not lasers or same old tokawhatever...

    Nevermind PSI, what of whales catching fire from all them metric gallons of molten salt?

    Pulsed helium3 fusion in a magnetic bottle, not lasers or same old tokawhatever...

    Was thinking concrete diving bell. Bubble going nowhere without dissolving first... Does it work if air inside the bell is imperfectly separated from water by a floating floor or tarp? How might maintenence compare to a weighted baloon?

    https://www.engineering.com/story/energy-storage-in-underwater-balloons I'm geussing compressed air can't be in direct contact with water or it'd just dissolve? Mention in passing but neglect to say how or how long they might store heat from compression to use for later decompression. That...

    Not to worry, any loose trillions will find other pockets.

    Pulsed helium3 fusion in a magnetic bottle, not lasers or same old tokawhatever...

    The breeding reactor doesn't aim to make useful power, only mixed fuel. Half the bred fuel will be clean fusing Helium3, the other half dirty Tritium. What to do with a spray of extra neutrons, maybe breed more Deuterium? Nothing will be done with Tritium but sell it or sit on it till it decays...

    Pulsed helium3 fusion in a magnetic bottle, not lasers or same old tokawhatever...

    Timeframe of the problem. Take a milisecond pulse, stretch and shape it over 1/120th of a second to make a half-sine. Else repeat often enough to pulse frequency modulate a half-sine. Not about storing for days...

    Pulsed helium3 fusion in a magnetic bottle, not lasers or same old tokawhatever...

    What concerns me are resistance and inductance from/to a basement of capacitors. Each requires more cable. Brief pulses want a solution on a short leash. Avoiding turbines should not mean throwing a flywheel out with the bathwater. Borrow a homopolar motor/generator or compulsator from railgun...

    I suspect from plentiful Deuterium, they intend to breed and sell Tritium and He3 if not electricity. Problem with fusing Deuterium to Deuterium is the dirty neutron it throws and the Tritium it often makes. If you fuse Deuterium to He3 which is clean, you also sometimes fuse Deuterium to...

    Pulsed helium3 fusion in a magnetic bottle, not lasers or same old tokawhatever...

    Not the latest from Helion, but maybe the techiest. My search here finds no earlier mentions of it. Strangely, no steam turbine needed. Confinement field returns electricity to a basement full of caps. Why must narrators all have annoying accents?
