I get .6 kwh, roughly. If a storage battery can produce 60 amp hours at 12 volts, that's roughly .72 kwh. Four batterise and you have enough tp run the light bulbs and the dishwasher. A little circuit trickery and you boost the voltage for the final reading.

Chances are, the fool arrived at 4.5kW from the amount of power required to accelerate the flywheel, charge the capacitors, or power whatever energy-storage device he's got hidden in the dishwasher. Otherwise, requiring a constant 4.5kW input to get 300W output is a pretty inefficient and poor first step on the road to free energy. Most modern internal combustion engines are more efficient than 6.7%.

I doubt he is the fool. He has us writing about him, not the other way around.
