In the heat of summer, either you shut the windows and crank up the AC, or pull down the blinds and stumble around in the gloom. At least, that was the case. A team at the Lawrence Berkeley National Laboratory has developed a new smart window that lets people choose what they want to let into their home, filtering out visible light, near-infra-red light, or both. Using a thin layer of nanocrystals that change state when electricity is passed through, will enable people to save on home energy bills by keeping the bulk of the Sun's heat out of the home without sacrificing the natural light. Now all we have to do is hook this up with one of Samsung's touchscreen windows and we'll never have to leave home again.
