MIT researchers have found a way to give your ordinary windows other uses than allow you to look through it. They invented a special coating that can be applied to the window, which in turn transmits the light its edges, to some solar cells. In this way you’ll still be able to see clearly through the window and collect solar energy.
“We think this is a practical technology for reducing the cost of solar power,” said Marc Baldo, an MIT electrical engineer.
They say that the materials used are not expensive at all and they plan to launch their invention commercially within three years.
Now, that’s a good invention!
