>There is no way that this wind turbine will be more profitable than a normal one given the pretty crazy cooling requirements. As long as the insulation method for the superconductor is good, once it is cool, keeping it cool should use surprisingly little energy, especially compared to the output of one of these things. >Also I don’t really understand why they chose that kind of superconductor that apparently has to be cooled to -240 when there are other superconductors that need to be cooled to just 150K... They do the same for a lot of the SMES systems - https://en.wikipedia.org/wiki/Superconducting_magnetic_energ... - Apparently the difference in cooling costs isn't that much and there are a variety of benefits to using the low temp ones that more than offsets that cost. *edited to correct brainfart |
