Although windows can naturally heat buildings in the cold seasons, some hot sunny days might make you wish that windows would just go away. Scientists from Japan have recently designed new technology that will make windows seem to disappear by turning clear, transparent glass into mirrors.The National Institute of Advanced Industrial Science & Technology (AIST) has developed a thin film for a mirror that allows one to switch between the reflective and transparent states. The prototype as seen in the above picture measures 60 x 70 cm. According to scientists, an estimated 30% energy savings can be achieved due to a reduction in air conditioning needs. This material can also be applied to transparent materials besides glass and more applications may yet be discovered.
