The thing about perpetual motion machines, is that they just might lead to other useful discoveries. I remember when I was a kid playing with remote-control cars, I was trying to add a wheel which would put energy back into the battery as the car drove around and stopped. A friends father explained to me that this was an attempt at creating a perpetual motion device, and that it was a pointless exercise. Of course, it was only a step away from understanding hybrid drive systems. I'm not saying I was the first person to think of it, or invent it, but it is a very real possibility that I would have become more interested in science and technology as I made smaller discoveries along the way, rather than being convinced that there was no point in trying, because nothing would ever work. It took me about 20 years to find my way back into creating.
