Can Brownian motion do work?

According to the latest episode of Eclectic Tech, Richard Feynman argued that Brownian motion cannot do work, but researchers at the University of Arkansas have demonstrated that it can by generating an electric current from Brownian motion in a sheet of graphene. You can read more in the physics journal article by the researchers.

Unfortunately this will be the last episode of Eclectic Tech. This last episode had several interesting stories. In addition to the story above, the episode discussed synchronizing clocks by observing cosmic ray events, a new bioinspired metamaterial, and NASA’s Inspire project.
