A Thermal Electric Generator, these devices produce electricity when heat is applied (the Seebeck principle). They usually are very inefficient, but can be practical in some applications. There’s the thermocouple, which is twisted wires of dissimilar metals, or the solid state type unit known as a Peltier module. This effect is reversible, generating heat and cold when electricity is applied. See the following resources:
