This invention is about a power system that captures heat, holds onto it, and then converts that stored heat into electricity. It works by using a device that generates power from a temperature difference, with one side kept hot by a heat storage unit and the other side kept cool by a cold storage unit. The patent specifically focuses on using materials that change phase to store the heat and cold, and it generates direct current (DC) electricity.
Why it matters: Since 2011, advancements in thermoelectric materials have led to more efficient generators, while phase change materials have seen improvements in energy density and stability. These material science developments could make the system's thermal-to-electric conversion and storage more practical now.
