Now here's a fun link, and a good one for folks to browse: The Museum of Unworkable Devices.

(from the ScienceMag review): The Museum of Unworkable Devices gives students an entertaining way to test their physics know-how. The mechanisms depicted here are all real designs, but they would never work because their creators misunderstood or overlooked crucial physical principles.

Curator Donald Simanek, an emeritus professor of physics at Lock Haven University in Pennsylvania, gathered many of the designs from history books and received others from readers--some of whom believed their submissions were sound. Using basic physics, he clearly explains fatal flaws with contraptions such as this variant of the perpetual motion machine. The north poles of the outer ring of magnets all face inward, and by repelling the north pole of the central magnet and attracting its south pole, they supposedly create an ever-turning rotor. The main fault is that the shield surrounding the central magnet is subjected to forces equal and opposite to the forces on the magnet, canceling out the rotation. The design flaws can be subtle, and Simanek leaves several examples for readers to figure out.

Byrd, thanks for the link. I love stuff like this. Kinda reminds me of this show on PBS called Red Green. Its a show out of Canada. Its stars a guy who is always coming up with all these wild inovations made form all sorts of junk laying around their lodge..and of course, the "handyman's secret weapon" Duct Tape.
