Scientists from Japan have developed this new technology which can make a transparent glass turn into a mirror at the flip of a switch.
How can this be of any use to us: Just think of this, when it’s a hot sunny day outside you can keep your interiors cool, cutting the cost of your cooling by turning the transparent glass into a mirror which will deflect the sun. On any other day when the temperature drops, one can turn it back into the normal glass letting the sun’s rays inside & help in heating.
