US Pat 7053576 Energy Conversion Systems by Correa

"The motor response far exceeds the conventional input power, indicating that the whole system can be tuned to resonance such that optimal power capture inside the reactor takes place, the critical limit rate lying at around 60pps, when the motor response is firmly within the pulse response plateau. At this juncture, the break-even efficiency for the measured rates of energy flux over time reach 700% (overunity coefficient of 7), in keeping with the observations and the values we have made in the PAGD conversion system. In the proportional part of the curve, before the plateau is reached, even greater rates of break-even efficiency - up to >1000% were registered. The results constitute the first time we have been able to confirm the presence of output energy in excess of break-even over the conventional mass-bound evnergy input in the PAGD inverter system and the results are comparable to what we have observed and previously reported for the PAGD converter system."..pg29.
