High-power thermoelectric generator utilises thermal difference of only 5°C

Thanks. If that energy is stored in a battery or capacitor, how could it bleed off any excess charge (in your example 10 v 12uW). Is this a thing that’s is problem anywhere?

Getting rid of a few microwatts is never a problem. If these things behave like Peltier elements, they'll simply float their voltage up to a design maximum then stop extracting energy as the electric field balances the energy of the electrons they're trying to extract from.
