Smart Glass which has been seen hinted to in American popular culture, as early as 1982 in Blade Runner, is fast gaining main stream appeal. What is Smart Glass, aka Electric Privacy Glass (EGlass), you ask? It is glass that is electrically switchable glass or glazing which changes light transmission properties when voltage is applied. Smart Glass is usually used for windows and skylights. When activated, the glass changes from transparent to translucent, partially blocking light while maintaining a clear view through the glass. Another type of smart glass can provide complete privacy when activated.
So what makes this glass of intrest to those who follow green technologies? Smart glass can darken in response to the increase or decrease of window temperature automatically, thus helping cut down heating and cooling bills. Smart Glass is another way to help make your home or building more energy efficient. The use of smart glass can save costs for heating, air-conditioning and lighting and avoid the cost of installing and maintaining motorized light screens or blinds or curtains. When opaque, liquid crystal or electrochromic smart glass blocks most UV, thereby reducing fabric fading.
Techie cool, I fully expect that we will hear about and see a lot more smart glass in the future!
