Taylor's viewpoints and suggestions—is ahead of its time and still applicable today. The Santa Claus machine and Pugwash According to Freitas and Merkle, the only known extant source on Taylor's concept of the "Santa Claus machine" is found in Nigel Calder's Spaceships of the Mind. The concept would use a large mass spectrometer to separate an ion beam into atomic elements for later use in making products. Taylor was a member of the Pugwash Conferences on Science and World Affairs and attended several of its meetings during the 1980s. After his retirement he lived in Wellsville, New York. Freeman Dyson on Taylor Freeman Dyson said of Taylor, "Very few people have Ted's imagination. ... I think he is perhaps the greatest man that I ever knew well. And he is completely unknown."
