Thin, iron-based generator uses waste heat to provide small amounts of power

Researchers have found a way to convert heat energy into electricity with a nontoxic material. The material is mostly iron, which is extremely cheap given its relative abundance. A generator based on this material could power small devices such as remote sensors or wearable devices. The material can be thin so it could be shaped into various forms.
