I love this kind of "perpetual" machine kinda thing. While there isn't anything that is truly energy free, there are many highly efficient machines that require very little energy to get started that produce tons of energy.

 Another thing that I love are those little black and white things that are in a vaccum and when you expose them to sunlight they start spinning really quickly. = ) Woot for science. xD

Just looked it up, it's called a Crookes Radiometer.
