Large Superconducting Magnets for New Energy Technologies

  • Chapter
Advances in Cryogenic Engineering

Part of the book series: Advances in Cryogenic Engineering ((ACRE,volume 24))

Abstract

Extensive and far-reaching plans are now being made for the development of new energy conversion technologies, which could begin to make a useful contribution to the supply of electric power by the end of the century. Three of these technologies demand the use of superconducting magnets on a scale that is extremely large in comparison with anything attempted so far; they are magnetohydrodynamic (MHD) power generation, controlled thermonuclear fusion, and magnetic energy storage. The challenge presented by these projects lies not only in their formidable size, but also in their need to attain new, high standards of reliability and safety, without jeopardizing the economic competitiveness of the complete system.
