Princeton Smart Windows
Eco-friendly, cheap smart windows
Princeton University engineers have designed UV-powered smart windows that can be controlled from an app. The windows change tint - from transparent to dark blue - in response to electric signals sent by UV-reactive solar cells. With the app, they can be used to adjusted the room's lighting and temperature using natural light. According to the engineers, the feature could cut energy costs by up to 40%. Besides being eco-friendly, the system is also cheap since the laminates can be easily applied to existing windows.

These windows could equip smart homes and buildings in a environmentally and economically smart city. This technology helps to optimize natural and endless resources: daylight and solar energy. This simple, frugal innovation is easy to adopt because it adapts to existing windows.
