Work can be extracted from a heat engine as energy flows from a hot body to a cold body. For example, as energy flows from the sun to Earth, a photovoltaic solar cell can extract power in the form of electricity. Similarly, a thermoradiative cell can extract power from "hot" Earth as energy is radiated toward cold space.
