Resumen de: US20260018710A1
The invention utilizes the heat storage capabilities of the mineral family of zeolites. Zeolite media is stored in a container. There is a place to add water to the zeolite in the container that will then release heat. The zeolite media releases its heat and heats a coil that is within the container and extends outside the container to heat a battery or a surrounding area. When the heat stored in the zeolite is exhausted it is recharged by using the heat coil in reverse to heat the zeolite and evaporate the water. The steam leaves the container through a one-way steam valve. Once the water is evaporated the zeolite is recharged with heat and ready for another use. This invention has a simple functionality store heat in zeolite, add water to release heat from zeolite, reheat the zeolite when evaporating the water. The invention contains the infrastructure required.
