I understand that it wouldn't work. But I'm curious with the development of nano technology, has anybody ever constructed a real life brownian ratchet to visually verify Richard Feynman's analysis?

On a scale of 1 to 10, actually being able to see the failure would be pretty cool...

Yes, molecular ratchets have been studied alot. Here's one of the first realisations:
