Talk:Brownian ratchet
From Wikipedia, the free encyclopedia
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)
This article makes a claim that ratchet slippage somehow prevents the ratchet device from producing work. The article should reference such a claim as an unproven theory until an appropriate reference is included in the article showing proof that slippage prevents the ratchet device from performing any work. Being one who has written many of simulations, include a trapdoor simulation, I believe such slippage is merely a technological issue, not a limitation.

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
