      jhewitt,

      A drinking bird is by no means an example of "overunity". The bird relies on external sources that require energy, ( obtaining a glass, filling up the glass with water, placing the glass near the bird, refilling it when it evaporates, etc.). This is no different than a battery hooked up to a 'black box". In fact, the energy required to make the bird work compared to the infinitesimal amount of energy produced by the bird, makes this a very wasteful and inefficient machine. Hardly overunity.

      Your reference to brushless motors for charging a battery (while you admit is not overunity), is even more wasteful. Why can't you people understand that no device is free?  Yes, a brushless generator has less friction than a typical generator, but it will NEVER deliver more energy than it takes to run it. Your comment about "the car has to push the wheel anyway" shows your lack of understanding. Yes, the car has to push the wheel, and if you attach a generator to it, it will have to push the wheel harder, draining energy, energy that is greater than  the generator produces....

      Now, you can use a motor/generator to aid in BRAKING; in other words, use the load of the generator to help slow the vehicle, and recharge the battery. Of course that isn't overunity either, but there are some efficiencies to be had from such an arrangement.

      Guess what, it's been DONE FOR YEARS...

      All in all, I find your post thoughtful, but still with the same misconceptions that plague so many  "believers".
