Winter warfare is loosing its peculiar charm

Charlsy Panzino for Army Times

Researchers are working on a way for soldiers to generate heat in cold environments instead of piling on multiple bulky layers to their uniforms.

By applying a silver nanowire coating to the uniforms, troops could theoretically dial up the heat to keep themselves comfortable, according to researchers at U.S. Army Natick Soldier Research, Development and Engineering Center in Massachusetts.

The silver nanowires form an electrically conductive network that when hooked up to a low-power battery can heat up polyester and polypropylene, research bioengineer Paola D’Angelo told Army Times.
