Windows that become mirrors at the flip of a switch
A fancy new glass has been developed in Japan, one that promises to cut down on the energy usage of buildings everywhere. It looks like a normal window regularly, but at the flip of a switch it turn to a mirror. When used as exterior windows, the mirrors can deflect the sun on hot days. This keeps the interior cool, cutting down on AC costs. When the temperature drops, you can turn the windows back into regular windows, letting the warm sun filter on through and lowering heating costs.
