Really, really, really Stupid question (yes, capital S stupid). Several hypotheticas here that got me thinking:
If superconductor exists at room temperature, and if I understand you correctly, it can hold a charge, essentially, indefinitely.
Could I get a roll of it and charge it and throw it at someone to kill them? Or could I fry a passing car by throwing it at the car?
- segfaultbuserr 3y agoYou certainly can use it as a batteryless inductor coil to zap people, similar to how you zap people with a charged capacitor. But a superconductor is limited by the magnetic field strength it can support. When the magnetic field strength goes up beyond the critical field by increasing the current, superconductivity is lost. In superconducting magnets, this causes a catastrophic failure called a "magnet quench". So a superconductor cannot store unlimited energy. In the original LK-99 claim, the critical current is 200 mA, it's not much.
