I should probably explain. If you drop your toast it always lands butter side down, right? But a cat always lands on its feet, so you take a piece of buttered toast and duck tape it to a cat's back, butter side up. If you drop the cat from about 5 feet up, it will fall, spinning as it goes down, until it reaches about 18 inches height, then will just spin at high speed without ever touching the ground. This can be attached to a generator and be a relatively carbon-neutral source of energy to charge electric cars. The technology has been there for years but has been suppressed by Big Oil through their political influence through PETA. All we need for a sustainable future is for the patents to be used.
