This Old House

Ross Trethewey, co-host of This Old House, visits Prof. Vladimir Bulović, director of MIT.nano, to learn more about the future of solar technology, including an electricity-generating film that can be applied to windows and other materials. “Dramatic advancements are on the horizon,” says Bulović. “We can make solar cells that don’t weigh very much at all so deployment of them on top of your roof could be as simple as unrolling a carpet and stapling it to the roof with a plug. Maybe your windows will be turned into solar cells.”
