I found a video on YouTube where an Australian inventer came up with a generator that is powered by magnetics. In other words a generator that doesn't run on anything, and once it starts moving it could run indefinately. I found the website, but it looks like one of those rip off sites that tells you the cost of something 3/4 of the way down. And that is just for how to build one, not buy one. But, never the less its interesting.
