Say goodbye to power cords and even to wireless charging stations. The old-fashioned way of charging electronics simply isn’t good enough for the makers of a new smartwatch called PowerWatch. There’s apparently no need when this smartwatch uses your body heat to maintain its charge.

The PowerWatch is the result of five years of research and development by Menlo Park, Calif.-based Matrix Industries — with a core team consisting of PhD graduates from Caltech, MIT, Harvard, and University of California, San Diego.

The watch uses thermoelectric technology to convert changes in heat to electric power. As the company’s Indiegogo page claims, it’s technology that NASA has used to power the Voyager spacecraft and Curiosity, the mars rover. So far, the technology hasn’t appeared much in consumer applications.
