That's exactly what I was thinking. Gravity and friction and all the other annoyances that have plagued perpetual motion for thousands of years. But in the heart of space with no gravity and no friction, then such a device could be used to power a spaceship. At least that's what I figured. -----Original Message----- From: piclist-bounces@mit.edu [mailto:piclist-bounces@mit.edu] On Behalf Of Mark Chauvin Sent: Friday, February 10, 2006 11:37 PM To: Microcontroller discussion list - Public.

The cat tried to land on its feet, but ended up hitting the ground kind of sideways, let out a wierd noise, the bread fell off and the cat ran away. I think it couldn't twist very good in the air with that thing on him, and he wasn't too happy about it either. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
