Superconductors are a special type of material that when cooled to 4K or 77K they have zero resistance.
This means that once a current is started in a superconductor, there is no resistance to stop it and the current will go on forever.
Is this an example of a perpetual motion machine? Will superconductors be able to supply infinite energy perpetually without having energy put into the system?

Answer #1

Is this an example of a perpetual motion machine?

No, this is not an example of a perpetual motion machine.

Reason: Unlike superconductor, a perpetual motion machine is a hypothetical machine that can do work infinitely without an energy source.

Will superconductors be able to supply infinite energy perpetually without having energy put into the system?

No, this is not possible. Superconductor will also require energy input. Only thing is that, the superconductor will be more efficient in electricity transmission as there are lmost no losses.

Energy input is required for superconductor because it wouldn't be able to provide any electrical energy from the system for use or application to any appliances without getting any input electrical energy.
