If we’re talking science function anyway, could it be a superconductor at room temperature? Or would it be impossible to build logic out of that?
- sp332 5y agoEven if it's very conductive, it still has to dump all that heat somewhere, so it will get very hot or just melt/burn eventually.
- flumpcakes 5y agoA superconductor is a material with zero resistance, so it does not generate heat with electrical flow.
- MayeulC 5y agoUnless it's doing adiabatic computing, of course. When computations are reversible, you don't have to waste energy to destroy bits. https://en.wikipedia.org/wiki/Reversible_computing#Reversibility https://en.wikipedia.org/wiki/Reversible_computing#Reversibi...
