Stephen Tse, Ph.D. Department of Mechanical and Aerospace Engineering, Rutgers University validated up to 340 kW of power produced by BrLP’s proprietary hydrino plasma reaction maintained in its SunCell® using molten metal bath and water bath calorimetry. This report includes description of the test apparatus and test procedure, a systematic development of the proper forms of energy conservation to be applied in the calorimetric measurement, experimental calibration of the heat losses in the tests, and analysis of the thermal and electrical data to obtain the calorimetric measurement of plasma energy release. The thermal Tests were performed on four-inch cubical stainless-steel plasma cells, each incorporating a 2.5-3.4 kg internal mass of liquid gallium which served as (i) a molten metal reservoir, (ii) acted as cathode while a tungsten electrode acted as the anode in formation and operation of the very-low voltage, high-current plasma when electrical contact was made between the electrodes by electromagnetic pump injection of the molten metal from the cathode to anode, and (iii) further served as a molten metal bath for calorimetric determination of the power balance by molten metal calorimetry. The plasma formation depended on the injection of H2/ 1% O2 fuel and HOH catalyst source at a recombiner wherein the corresponding power from the mixture’s combustion was negligible and occurred outside of the calorimeter. There was no chemical change observed in cell components as determined by energy dispersive X-ray spectroscopy. Thus, the maximum excess power from conventional chemistry was zero. These results demonstrate that BrLP has advanced the SunCell® engineering to operate continuously at MW/liter power densities which has broad commercial applications as a safe, inexpensive, autonomous, 100% green power source. The power gain was sufficient to output net electrical power to the grid using mainstay turbine-generation systems.
