Claim:
1. A portable, thermoelectrically powered device, the device comprising: a body defining an interior extending between an at least one first aperture at a distal end, and an at least one second aperture at a proximal end, the at least one first aperture and the at least one second aperture in communication with an ambient environment; a thermoelectric generator located on and extending inward through a portion of the body to the interior; a heat sink housed in the interior and in contact with an inner surface of the thermoelectric generator, the heat sink defining an internal first cooling channel extending between and continuous with the at least one first aperture and the at least one second aperture, the body and the heat sink defining a second cooling channel there-between, the second cooling channel extending between and continuous with the at least one first aperture and the at least one second aperture; and circuitry in electrical communication with the thermoelectric generator, the circuitry comprising a transistor oscillator, a step-up transformer and a decoupling capacitor, the circuitry in electrical communication with a power sink, such that in use, a temperature gradient across the thermoelectric generator is sufficient to result in generation of at least 25 microwatts of power.
