To be honest ex i am amazed this is not known about from a theoretical point of view.
The devices i spoke about were shown to work on this university program, so i wonder what happened to them, the elderly guy, Grey hair and quiet chubby was wearing a white overall and sitting behind a desk demonstrating an array of light bulbs, i could see no external power sources but then i could see no transformers or wires so it must have had the electronics inside the box of the light array , i cannot remember the exact number but it was a square array, maybe 5 x 5 bulbs all lit, he spoke in a very scientific manor, but i was too young to understand what he was saying.
I have never ever seen this device since.
Not surprising it has disappeared, i have seen numerous inventions that could have revolutionised the world, disappear in thin air even when they were proved to work, how's this one, again late 70's maybe early 80's a guy invented a liquid that when drunk would cancel any alcohol in the blood stream, the guy had previously drunk alcohol prior to the test, he blew into a bag to show he was over the legal drive limit, drank this liquid and a few minuets later blew into another bag and he was clear of all alcohol in his blood stream. boy i could have done with a few of those in my younger days
Then there was a guy who invented another liquid which when sprayed onto an electric drill, the drill could then be immersed into a bowl of water and still work without electrocuting the chap holding it.
and recently a guy invented a liquid and repels heat, he sprayed some onto an egg and took a blow torch to the egg, after a short time he removed the blow torch and held the egg and said it was cool, he then cracked it to prove it was still raw, he died shortly after and never had a chance to reveal what the formulae was.
All these things were shown to work but for various reasons have never come to light
