With Andrea Rossi’s Hot Cat promising a minimum of a COP of 6, there is much speculation going on about the benefits and applications of this type of energy. But, when Rossi reported a conservative COP of 13 in sustained running in October, the excitement mounted.
This high COP is figured after the input of electricity or natural gas for heating purposes, which is done about every hour. Otherwise, the Hot Cat runs in self-sustained mode. The COP 13 includes the fuel used to start the reaction as well as the fuel within the cells, themselves. This fuel is hydrogen and nickel which, when it interacts, creates this massive release of energy.
So, just how much hydrogen and nickel does it take to produce this much energy?
Robert Godes, of Brillouin, said, as quoted in OilPrice.com, that their boilers produced and tested by his company use only hydrogen, with nickel as a catalyst. The amount of hydrogen used is contained in a drop of water about the volume of a pencil eraser. According to Godes, this single drop of water will provide as much energy as 2 4-gal. drums of gasoline.
The very idea that you could get as much energy from a drop of water as from 96 gallons of gas is incredible. But, there is more. The Brillouin boiler doesn’t have to be refueled for 5 years! This boiler reaches temperatures of up to 500 degrees C, in comparison to Rossi’s Hot Cat which reaches a minimum of 600 degrees C, and upwards to over 1000 degrees C. A rough comparison of the two would be a COP of 4 or 5 for the Brillouin unit.
To put things in perspective, a nuclear power plant has a COP of about 1.5.
Whatever amount of hydrogen and nickel the E-Cat and Hot Cat have in them, the efficiency of those units is reported to be as much as three times that of the Brillouin boiler. That amounts to an equivalent of 288 gallons of gasoline per each equivalent charge. Since the E-Cat line must be refueled once every 6 months, it’s pretty safe to assume that it uses even less than a single drop of water in its fuel system.
