Clothing could reflect 90 percent of body heat by dipping clothes in a solution made of AgNW, also known as silver nanowire. Regular clothing only reflects 20 percent of body heat back at your skin, making nanowire-coated clothing much more energy efficient. The study was conducted by Professor Yi Cui of Stanford University and his team of researchers. Since metal nanowire coating can conduct electricity, all you would need to do is connect a battery to the clothing.
They see metal-coated clothing as a way to combat the rampant energy
demands of the winter months. They report that "47 percent of global
energy continues to be spent simply on indoor heating." We are
told global warming is caused by energy use. Now we find half of
that is caused by trying to keep us warm. Hmmm
