A company called Industrial Heat just received an international patent for LENR. During October 2014’s independent verification of their LENR device, called an E-Cat, by PhDs and Professors at the University of Bologna, the device was run for 32 days continuously without stopping, producing over 2 MWh of heat energy and a net energy gain of 1.5 MWh from just 1 gram of hydrogen, in a device weighing less than 500 grams. The hydrogen had not run out by the time they manually stopped the reaction to conclude the tests.
Total electrical input powering the reactor over the 32 days was 0.6 MWh, total heat energy produced was 2.1 MWh. Undoubtedly signifying that a nuclear reaction was taking place. The device has an amazing power to weight ratio of 1.6 GWh/kg but could be way more if the reaction was allowed to run until all the fuel was consumed.
