Abstract: Provided is a portable, thermoelectrically powered device in form of a modified vessel and attachments, for extracting electricity from the temperature differential of liquids, slurries, and solids, and that of ambient air. The device utilizes two container surfaces with a temperature differential between them, and at least one thermoelectric generator in electrical communication with circuitry comprising at least one step up DC-DC voltage converter. In a preferred embodiment, the device includes a second DC-DC voltage converter and a storage battery to provide electrical power at a selected voltage to external personal devices such as cell phones, iPods, flashlights, and tablets for recharging or operation of those external devices.

Abstract: Provided is a portable, thermoelectrically powered device, such as a flashlight or headlamp. The device comprises at least one thermoelectric generator for extracting body heat from a user, the Thermoelectric generator located on and extending through an elongated open ended outer shell, a heat sink in contact with an inner surface of the thermoelectric generator and configured to provide an elongated first cooling channel therethrough, 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 about 25 ?W of power.
