It doesn't work like that. Non-reversible computations necessarily produce heat. The superconducting wires will not heat, but the CPU will.
I touched on this in a previous thread[1], but superconductors only stay superconducting below not just a critical temperature, but also below a critical current density and critical magnetic field strength.
These limits are different for different superconductors. It could very well be this superconductor has really high critical temperature but really low critical current density, in which case you can't have lots of current at zero resistance.
That doesn't make sense. Power has to be consumed by something. All energy ends up as heat, so if the computer isn't heating up then the power consumption is 0W, not 1000GW.
>Or a flying car.
A flying car with superconducting motors would still have to expend the energy to stay aloft by pushing air downwards. Even without thermal losses to electrical resistance, you'd still have losses to friction from the moving components.
So in theory you could have a ridiculous computer that runs 1000GW of power through it without heating up. Or a flying car. Or power cables that lose nothing during travel.
Naturally that’s why it doesn’t make sense. It’s too game-breaking to be possible in normal conditions.
Glitching something out by making it basically maximum cold makes sense because you’re making it fully still so that it stops messing with the current. Glitching something out by squeezing it until it can’t move makes sense. Leaving it in a normal room means it would have to be something completely crazy.
