Thermoelectric materials, putting it simply, are able to generate electricity via differences in temperature. If
thermoelectric felt were used to make a jacket, for instance, it could generate a current using the temperature gradient between the warm interior and cold exterior of the garment. Like many such promising technologies, however, the cost of thermoelectrics is something of an issue ... although thanks to a new process developed at Germany's Fraunhofer Institute for Material and Beam Technology, that might not be the case for much longer...
