This strange looking pan is a device to generate power from a low temperature heat source. By using the seebeck effect, it is able to produce enough electricity to charge a cell phone and other USB devices. The best part about this contraption is that it has no moving parts.
The device has a nimh power pack which stores electrical energy for use whenever you need it, the power pack can be detached for use anywhere. The output is 5V through a USB port. This device would work especially well were there is snow available for extra cooling – for example off grid cabins in remote (snowy) locations. It could serve as dual purpose - melting snow for water and producing electricity ? The bigger the temperature difference between the two sides of the peltier the greater the power output.
This idea is not new, it has been around for a long time. See here for some very
old thermoelectric generators
The peltiers produce 0.6W of power to recharge the battery pack.
