Useful energy from ambient heat

Physicists at Arkansas University have discovered that graphene performs occasional tandem rippling caused by the bombardment of surrounding kinetic energy, rather than random rippling as with other materials.

This enables harvesting of the causal kinetic energy using an electrical circuit as a useful source of energy, wdownloadhich they have proven. They state that 10 x 10 microns of the material can produce about 10 microwatts continuously.

Doing the maths to scale that up, suggests a square metre of the material/circuitry would produce 100 kWatts – an incredible figure. Though presumably there would not be enough local ambient heat to sustain such a flow of energy. It also seems to me that on the surface the process breaks the second law of thermodynamics which prohibits deriving work from ambient heat!
