Thermoelectric coolers (TECs), also known as Peltier coolers, are semiconductor devices that rely on the ... “It's much more difficult to control the flow of heat than it is to control ...

Peltier modules, or thermoelectric modules, are thermal control devices that provide both heating and cooling effects, maintaining the surface temperature at a set target. These modules are ...

The small Peltier “solid-state heat pump” module in the lantern acts as a thermoelectric generator, converting heat from the candle into electricity for the LEDs. The genius of the device is ...

So something like this heat-powered stove-top fan can come in handy. Such fans, which use Peltier devices to power a small electric motor, are readily available commercially. [bongodrummer ...
