Nature 2002: "Second law broken. Researchers have shown for the first time that, on the level of thousands of atoms and molecules, fleeting energy increases violate the second law of thermodynamics. [...] They found that over periods of time less than two seconds, variations in the random thermal motion of water molecules occasionally gave individual beads a kick. This increased the beads' kinetic energy by a small but significant amount, in apparent violation of the second law."

No thermal fluctuation can produce a kick lasting for so long (up to two seconds). Only a local FLOW can push the bead in this way, and the flow, generated by a local electric field, is essentially identical to the flows in this system:
