Information. , Nitinol Heat Engines for Economical Conversion of Low Grade Thermal Energy, 13th Intersociety Energy Conversion Engineering Conference, San Diego, CA, 20-25 Aug 1978. An unusual metal alloy called Nitinol has found its way into the space and aeronautics industry. How To Build Your Own Generator that generates electricity free "Although originally suggested by Nikola Tesla in 1905, only a few permanent magnet motors-generators have been designed, that is, magnet motors where the power comes from the magnets, not an external, exaustable supply of electricity. To complete the discussion, SMA design challenges and methodologies are addressed and the future of the field is examined. A patent search on the Internet using the key words nitinol and engine turned up several heat engine designs. This invention was possible thanks to a.
