Question

what are the main factors holding back magnetic energy storage systems?

Answer 1

Superconducting Magnetic Energy Storage (SMES) systems store energy in the magnetic field created by the flow of direct current in a superconducting coil which has been cryogenically cooled to a temperature below its superconducting critical temperature.

Answer 2

The system would be more efficient withmetal pipe. Now we answer the compelling question, "how can I use a magnifying glassto heat the pool" for you! Each "hot spot" is 210 degrees. The result is about a half-degree rise in the water temperature (5300 Gal) over an eight-hour day using a one HP pump.
