Source: (PhysOrg.com) — It’s been seven months since Italian physicists Andrea Rossi and Sergio Focardi publicly demonstrated a device that they claimed could generate large amounts of excess heat through some kind of low-energy nuclear reaction (LENR). (Previous descriptions of the process as “cold fusion” are incorrect; although the process is not completely understood, it is likely a weak interaction involving neutrons, without fusion.) The physicists call this device the Energy Catalyzer, or E-Cat. Due to the major potential impact such a device could have for energy production, the scientists have received visits and inquiries from all over the world, but so far the claims seem to be lacking credibility.
