Where the hell did these people get there college degrees? As a mechanical engineering major, I can categorically state the a perpetual motion machine is impossible. Not only does it violate the first law of thermodynamics, but more importantly it violates the second law of thermodynamics. Work is produced by energy moving from a hot reservoir to a cold reservoir. It is impossible for heat to be completely converted to work (some heat has to go to the cold reservoir). Even if you had the most efficient parts and there was no friction or air resistance, an engine cannot be more efficient than a Carnot engine.
The Chromebooks are here, starting with Samsung's Series 5, a cute little number that promises instant-on access, 3G connectivity, and long enough battery life to web surf with the best of 'em.
