"The power gain of four times input power was sufficient to output net electrical power to the grid using mainstay turbine-generation systems.
The good news: best COP 4...
The bas news :
In this test power was supplied to the cell electrodes by discharging four capacitor modules over a period of 2.95 s as shown in Fig. 4. Because of the capacitor discharge, current and power generally decayed during this period while voltage was mostly constant at about 30 V. Current decayed from about 5.5 to 2 kA and power reduced from about 180 to 60 kW.
The machine can only work for some seconds (longest test 12'') to avoid overheating. Thus we are still at square 1! --> no power to grid.
