Cheaper superconductors and magnets will make MHD generators more affordable
MHD Generators could make zero emission coal generators affordable and efficient and MHD generators could also make nuclear power for space very light with an energy density of one to three kilograms per kilowatt. Magnets are about 22% of the cost. Superconductors and new permanent magnets (using nanomaterials) could make more powerful magnets that are …
