Could someone explain simply why a brownian ratchet is self defeating?

It's not an incredibly scientific explaination, but I did add sort of a plausibility argument for its failure that I've heard at talks on Brownian motors. Laura Scudder 01:13, 17 Feb 2005 (UTC)

could someone add a picture to this page? I found a couple (including an animated one here: http://web.mit.edu/8.592/www/lectures/lec20/ (hover over the pic to see the animation)) but I didn't add them to the article because I wasn't sure of the copyright stuff.

Thanks. -PB

[edit] scale

On a small scale brownian motion could be seen a lots of pools of different temperature. -Jeff
