New green technology could harvest body heat as energy | Inhabitat

Scientists have created thermocells, energy-efficient devices, that can harvest excess heat and convert it into renewable energy. They hope to create portable batteries that could be applied to many types of surfaces to harvest excess heat — including clothing to utilize heat from the human body as energy.

The group of 11 scientists who worked on this project published their study in the journal Renewable Energy. They are affiliated with The National University of Science and Technology in Moscow.

Thermoelectricity is the type of electricity that is generated by temperature differences, called temperature gradients. These are found everywhere, including around the human body. While this is an area of green energy with untapped potential, previously developed thermocells have a low output power.
