"he Energy Catalyzer (sometimes shortened to E-Cat) is an apparatus built by inventor Andrea Rossi, with support from his scientific consultant, physicist and emeritus professor Sergio Focardi. The 2009 patent application claims "a method and apparatus for carrying out nickel and hydrogen exothermal reactions," with production of copper. Although the patent cites previous works on cold fusion, one statement by Rossi asserted that it is not cold fusion, but rather LENR, Low-Energy Nuclear Reaction. A similar system, but yielding considerably less power, had previously been described by Focardi et al."
