Abstract: A method and system for environmental control and supplementary power generation in conventional and hybrid vehicle applications is presented. A thermoelectric heat pump function regulates vehicular interior temperature environments and uses the waste heat from a vehicles engine to power thermocouples and generate supplemental electrical current to power electrical devices. Thermocouples are used to gauge changes in temperature. The Peltier Effect is used to provide both primary cabin environmental control and supplementary power generation for motorized vehicle applications. Thermoelectric generators can be used for both primary internal climate control and supplementary power generation in the vehicular environment.
