piezoelectric fabrics (which generate electricity from movement-caused pressure), nor am I talking about
photovoltaic materials, although both of those could probably do the job. Instead, your jacket might be made out of a new thermoelectric material called Power Felt, that converts temperature differences into electrical voltage – in the case of the jacket, the difference between its wind-cooled exterior and its body-warmed lining might be all that was needed...
