System and method for efficient power utilization and extension of battery life

摘要: A circuit which extends the operational life of a main energy source coupled to load, said comprising power generator having heat and cooler thermally thermoelectric (TEG) for converting thermal into electrical energy; first capacitor TEG receiving storing from TEG. The further at least one switching element between converter generating regulated output, controller activating when charge stored on reaches predetermined level, thereby delivering via converter, reducing amount drawn source, extending source.
