now lets close the loop?
I contacted Greg when he was on the Joe Cell forum about a year ago and he said that although the closed looped did work the power output was so tiny that it was not worth pursuing.
I suppose its not the output power thats the issue but the whole principle of demonstrating zero point energy (or what ever it is) at work.
I think he said the setup was so difficult that most people could take some time to get it to work.
I have some 15/16" ball bearings, a few dozen magnets and some U channel.
