Abstract The ENECO records (1912-2007) consist of patents, contracts, research, office, and financial documents collected by the company. ENECO (formerly FEAT) was a private company that centered on cold-fusion technology and the commercialization of such technology. The majority of patents registered by ENECO were invented by scientists Stanley Pons and Martin Fleischmann. Technologies engineered by ENECO have had a great impact on the local and international scientific communities.
