By measuring the rate and scale of these graphene waves, Thibado figured it might be possible to harness it as an ambient temperature power source. So long as the graphene's temperature allowed the atoms to shift around uncomfortably, it would continue to ripple and bend. Place electrodes to either side of sections of this buckling graphene, and you'd have a tiny shifting voltage. This video clip below explains the process in detail: A Potential Source of Clean, Limitless Energy ‘By Thibado's calculations, a single ten micron by ten micron piece of graphene could produce ten microwatts of power. It mightn't sound impressive, but given you could fit more than 20,000 of these squares on the head of a pin, a small amount of graphene at room temperature could feasibly power something small like a wrist watch indefinitely. Better yet, it could power bioimplants that don't need cumbersome batteries.’
