Window Blinds that Help Take You Off the Grid

Window Blinds that Help Take You Off the Grid

While only a concept, if this genius idea doesn't make it to market we may just riot. Just awarded ID Magazine's Annual Design Review award, the Light in the Dark is a window blind concept that turns your Venetians into energy hoarders...

Designer Ivan Huber of Cincinnati, OH, thought up a Venetian blind system that, when the blinds are down during the day, collects energy from the sun and then releases it at night as needed. According to ID, "Photovoltaic cells on the blinds' exterior collect solar energy, which is stored in a lithium-ion battery pack within the valance. At night, the battery powers tiny LED lamps enhanced by a sandwich of materials that spread and diffuse the light: a layer of reflectors facing the window and a network of hexagonal lenses facing the room. The hexagons open to admit air and daylight then close tightly for insulation and privacy."
