       | The Elliot 803[2] was mostly magnetic logic.
       | 
       | Jeri Ellsworth made a video[3] demonstrating it back in 2012.

       | extremely hot thermopile powered magnetic logic computer.
       | Materials with a sufficiently high Curie point exist, as does
       | insulation, etc.
