    Abstract: A device and method for generating electricity. The device includes a heat source, a cold source, and a thermoelectric generating plate, having a first side and an opposed side. When heat is introduced to the heat source, heat flows across the thermoelectric generating plate and electricity is generated. In the present arrangement, because the hot and cold sources are in thermal communication with opposed sides of the thermoelectric generating plate, the thermal gradient or rate of heat flow across the thermoelectric generating plate is maximized. Thus, because the rate of heat flow is increased, the rate at which electricity is generated is also increased, and the size of the device is maintained, or minimized.
