Chernetski Plasmatron produced up to 5X more out than in

Free energy inventor from russia killed in 1992 after speaking to Hal Putoff and demonstrating his ability to transform pure dieletric field energy into any sized KW output.

The mysterious discharge stimulating additional energy extraction was called the "self generating discharge (SGD)". Measurements showed that part of the discharge power went back into the network as if two series-connected electromotive forces were at work.

Detailed description of Chernetsky's experiments were published in English. Power output was up to 500 Kwatts and the proof of a reverse current from the experimental system into the electric station was detected.
