But they're "converting" brownian motion to linear motion by pumping energy in, in the form of laser light.
Off hand, it doesn't _sound_ like anything in the system is even potentially OU.
But, of course, one would have to read the original article in PRL with care to figure out what's really going on here...
I would certainly like to know more about the "Brownian motors" they talk about cells using for protein trasport. My impression (very vague!) was that when cells transported anything it required an energy input, unless it was going down a concentration gradient.
