The device relies on the ability of nickel to absorb hydrogen that while doing so releases heat, significant amounts in fact, the power needed to run the device is rating at 400 watt hours per hour to produce 15,000 watt hours per hour from a lab bench experimental device. In lay terms the drive is about 4 one hundred watt lamps for 150 one hundred watt lamps of production a 37.5 fold gain quite a fine rate of return.
Brian Wang at Nextbigfuture.com figures the cost for electricity and heat
, after the heat is converted to mechanical energy and on to electrical energy, to be below 1 cent/kWh, in case of electric power made by means of a Carnot cycle, and below 1 cent/4,000 M J in case of thermal power production for heating purposes. Even if Mr. Wang widely misses the mark, this is stunningly cheap energy.
The device starts with a tripping of a switch and shuts down just as simply. The product other than power is a weak burst of gamma radiation when powered off. The consumables are the nickel and hydrogen and the device has an additive package for the fueling or reaction that is proprietary, which should be available when the patent is granted.
