More on Greer- the crackpot
In 2003 he appeared on that well known crackpot show 'Coast to Coast' George Noory and claimed that he had a working Free Energy device. (The transcript used to be on his disclosure project website but he removed it- wonder why? You can find the transcript at http://www.phact.org/e/z/greer.htm you read it and decide if he is a crackpot or not).
Aside from pseudoscience, and conspiracy theory he also makes the claim:
Remember, UFOs are secret not because people are so
afraid so much of extraterrestrials but because UFOs themselves are
running off of energy and propulsion systems that would replace the
need for oil and gas. So, the secrecy has been mostly out of greed,
not out of a security.
yeah, right...
