I am just not going to argue this point with you. I will kindly point you to some facts (those things in science), about the topic.
While my primary school of thought and education is social science, I have been a theoretical power source enthusiast since childhood. While there are some promising field in science (you know, that thing with facts) ZPE is not as a construct or application going to yield infinite energy. Ever.
The real question in energy production of this kind is transmission and/or harvesting. See, Tidal and wind are indirect harvesting of gravity and solar for instance. Finding ways to harvest them directly might
get one closer to unity.
My money is on A.M. radio though, since tons of it occur naturally in the universe.

The term Over Unity or Overunity, is often used to describe devices or systems which will produce more energy than is required to run them (free energy machines). Real over unity is simply not possible. It actually makes no sense "Over Unity" is equivalent to "More than the same" which is impossible. If a device were to output more electrical power on it outputs than was supplied to its inputs, it must have another power source. In the case of the so called 'Over unity' devices this extra energy on the output is said to come from the vacuum fluctuations (a.k.a. zero point energy).
Then again, it's not like we should trust people who have spent entire careers specializing a field of study over the mythological beliefs of a few mainstream hippies. http://news.bbc.co.uk/2/hi/6283374.stm http://www.rmcybernetics.com/science/physics/zpe.htm
Hubris is nothing more than obstacle to growth. Personally I start with assumption that I am entirely wrong, then I learn tons of stuff either way. When I start by assuming that I know everything, I end up learning nothing.
