Abstract
Describe herein is an energy storage system that includes a battery and a heat source. The battery harvests waste heat from the heat source to keep itself warm while storing electrical energy generated from a heat to energy transforming source. If the heat source is radioactive (e.g. radioisotope decay) a radiation hard battery is intimately connected to a waste heat source. The radiation hard battery harvests waste heat from the heat source to warm itself and to shield the radiation.
