United ENECO Cold Fusion photograph collection, 1992-1999

ENECO (formerly FEAT) was a private company that centered on cold-fusion technology and the commercialization of such technology. Based in Salt Lake City, Utah, ENECO was founded by Fred Jaeger, a Texas venture capitalist who had previously worked in technology industries. On December 2, 1993, the University of Utah announced the licensing of patent rights related to Martin Fleischmann and Stanley Pons’ research into cold fusion technology to ENECO. With the licensing, ENECO became responsible for paying to defend the patent rights to the cold fusion patents but gained the right to commercialize the patents. The company hoped to work with Fleischmann and Pons, who had left the United States and continued their research in France. In March 1998, the University of Utah announced that it would no longer defend the rights to cold fusion patents, and since the early 2000s the United States Patent and Trademark Office has rejected patents that claim cold fusion on the basis of inoperability.

In addition to its work on cold fusion patents, ENECO had development interests in the following non-cold fusion technologies: oxygen concentrators, N-type diamond semiconductors, and highly efficient thermo-electric converters. These technologies were developed under their individual subsidiaries (Oxydyne Inc., Semidyne, Inc., and Thermodyne Inc.).
