No, it is a thermoelectric conversion with a very low or no thermal difference between the anode and cathode parts. In all thermoelectric conversions there is barrier that prevents the free flow of electrons. The hot part of the thermoelectric converter provides the energy to the electrons to cross the barrier to the cool side. The barrier prevents the electrons from flowing back, acting like a diode. This forces the electrons to pile up, acting like a capacitor, until it is connected to a circuit to be drawn off to do real work. This paper seems to indicate that the single molecule thickness of graphene lowers the required hot side to the ambient room temperature. If it is proven to be true, it could revolutionize savaging waste heat from all mechanical processes and provide significant support to green power. However, there is a mountain of work to be done before anything real can come of it.

Nice explanation
M.D.V. ;) If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about? Help me to understand what I'm saying, and I'll explain it better to you Rating helpful answers is nice, but saying thanks can be even nicer.
