As far as I know, John Bedini also does not believe in the term of OU, because OU is when you can put something in and get far more of the same energy out from nothing. But here we are extracting energy from environment or aether that is already there, we are simply converting that energy into usable energy. Like when you put a water turbine into a river and convert the mechanical energy of moving water into usable electricity. Or when you operate a heatpump. In this case we are simply taping the sea of energy that is already there, but is not recognized by most of scientists. You can get more energy out than you put in, but you are not creating any energy, just converting from other forms. That's I believe is why he states that OU is impossible.
