We have improved the refractory liner and increased the operating temperature of the SunCell® validated by Dr. Mark Nansteel that was reported in the post of December 18, 2020. The 100 kW hydrino power was measured by Dr. Nansteel using the weight of steam produced over a test period by the SunCell® operated under continuous commercial power generation conditions. By the same method, the total output power increased to 250 kW at the higher operating temperature.
