Well,

It seems that the material offered on his website has different claims than the videos he had on youtube!

This is a quote from his website:
"Now for OU or Over Unity, well again in my opinion this idea is in error. If you think you are getting something for nothing then you have not looked back far enough in the chain of events leading up to the specific observational point in time. Simply stated in a Law derived by Newton, 'For every action there is an equal and opposite reaction'. This most certainly applies to potential energies of all forms, current and hypothetical. Conversion of energy into a kinetic form does indeed ripple in effect both forward and backward in time."

He clearly stated in the videos that he was getting overunity results and demonstrated it. But what HAPPENED? Was he threatened or what?
