A California-based company is commercializing an abundant, naturally occurring material that can turn waste heat into power.

Thermoelectric Material to Hit Market Later This Year | MIT Technology Review Skip to Content California-based Alphabet Energy plans to begin selling a new type of material that can turn heat into electricity. Unlike previous thermoelectrics, as such materials are known, it is abundant, cheap, and nontoxic. Thermoelectric materials can turn a temperature difference into electricity by exploiting the flow of electrons from a warmer area to a cooler one. Thus, they can theoretically turn waste heat into a power source. But an efficient thermoelectric material has to conduct electricity well with
