Andrea Rossi’s Leonardo Corporation has received a United States Patent that could cover his Ecat low energy nuclear reaction (LENR). Interestingly enough the patent US 9,115,913 B1 dated August 25, 2015, does not mention LENR, cold fusion or the words Ecat or energy catalyzer.
Instead it is for a device called a Fluid Heater. Andrea Rossi is listed as the inventor and his company Leonardo Corporation is listed as the assignee or owner. The Fluid Heater is described as:
“An apparatus for heating fluid includes a tank for holding fluid to be heated, and a fuel wafer in fluid communication with the fluid. The fuel wafer includes a fuel mixture including reagents and a catalyst, and an electrical resistor or other heat source in thermal communication with the fuel mixture and the catalyst.”
