Tiny Channels of Water Could Cool Windows and Cut Down on Air Conditioning Bills
30th July 2013
Like blood circulating through the human body, a new system out of Harvard harnesses channels of running water to cool windows that receive a lot of sun. The water carries away heat, leading to less work for air conditioners and a lower electricity bill.
The channels are ultra-thin and encased in a sheet of clear silicone rubber that is stretched over a window. They crisscross to create a mesh-like pattern. While the channels are visible when empty, they become transparent when they contain water.
