NMR Generator
None we know of
A French document named: A POWER PLANT AT HOME explaining that up to 30 times more Energy is Generated, by means of NMR, Magnetic Resonance, is an interesting read! Is it really NMR? or is it something else? Please Note: 173 might be MHZ and not KHZ!!! I was told it was KHZ and trusted in the direction...
A publication was published in a magizine I believe, "Science et Vie" nr.700 March 1976 (pages 42-45 ), which you can find below. Below that is a Translation, best we have done, so, to, further understand what was being said all those years ago.
