Harvesting Energy From Temp Differences
Seebeck effect = thermal gradient energy produces electrical
Peltier effect = electrical current across a conductor junction produces cooling / heating.
How it works
When DC voltage is applied to the module, the positive and negative charge
carriers in the pellet array absorb heat energy from one substrate surface and
release it to the substrate at the opposite side. The surface where heat
energy is absorbed becomes cold; the opposite surface where heat energy is
released, becomes hot. Reversing the polarity will result in reversed hot and
cold sides.
