I listen to late night talk show "Coast to Coast am" ;mostly to Art Bell and have a few books on physics,(One by Dr. kaku)and there are some who speak about how it's possible to build power units that produce more power than you put into it and others that simply get the power to run electrical appliances, tv sets, ect. from the air . "The Search for Zero Point Energy"; a book , tells of the quest to find such devices. One man claims there have been devices already built that do this in a small way but before the units can be manufactured for sale, the inventors are either bought off by the big OIL companies or the inventors are killed. Some claim the "Free Energy Devices" will never be allowed until there are no oil deposits left on Planet Earth and the Oil Companies need another form of energy to power their new electric cars, Hydrogen powered cars, or their new fuel cell cars. What do you think? Is the hope for a clean Energy source that gets its power from thin air a real possiblity or are the laws of Physics telling us that all of this is a pipe dream?
