1. An electrical system comprising:
- a supply voltage;
an electronic circuit which requires an operational voltage which is less than the supply voltage;
a thermoelectric heat pump which has two terminals, the first of said terminals being operatively connected to the supply voltage; and
a regulator having an input and an output, the input of the regulator being operatively connected to the second terminal of the thermoelectric heat pump and the output of the regulator being operatively connected to the electronic circuit to supply operational power to the electronic circuit.

Abstract
An electrical system is disclosed which includes a supply voltage and electronic circuitry which requires an operational voltage that is less than the supply voltage. A thermoelectric heat pump is interposed between the supply voltage and the electronic circuitry to produce heating or cooling using the excess power which would otherwise be dissipated in a regulator. A voltage regulator is provided between the output of the thermoelectric heat pump and the electronic circuitry to provide the operational voltage to the electronic circuitry.
