Smart Glass - Smart Window Technology

Mentioned by Bob Lazar in Joe Rogan Podcast. JRE Video: Smart glass or switchable glass (also smart windows or switchable windows in those applications) is a glass or glazing whose light transmission properties are altered when voltage, light or heat is applied. You’re probably aware that your windows can play a pretty big part in your home’s energy use. Windows stand as a last defense against winds and heating and cooling loss—but the glass can also keep out unwanted solar heat as well. That means you need to pay attention to the energy measurements listed on your window’s specs. You’ll need to look at the solar heat gain coefficient, which tells you how much solar radiation the window allows through the glass. The only problem? That number is a static measurement, so your windows let in or prevent the same amount of solar heat all year. But there are some parts of the year when that sun might be useful as passive heating, so you could use less energy in the winter, too. That i
