Each and every day, the sun showers our cities in solar energy. Every night, our cities emit light so bright that they can be seen from space. An industrial designer from the Bezalel Academy of Art and Design, Jerusalem, Israel, has designed a concept device called the UrbanTile that would harness the solar energy city buildings absorb during the day for their lighting needs at night. The UrbanTile is a small solar panel that can be flipped to reveal a light emitting screen. Banded together into rows, the panels become a window blind that forms a light and entertainment display.
The panels would made from aluminum and stainless steel with an OLED screen on one side and a photovoltaic panel on the other. Incorporating electrical motors to move them, they could be programmed to turn automatically at different times of the day. Designed to be mounted into windows, the panels could be turned to rest at various angles allowing light in during the day whilst absorbing solar energy. In the evening, the OLED screens would be turned to face indoors to light up rooms and also provide a bank of screens for media playback. At night, the light emitting side could also be turned outwards to produce patterns of light on the sides of buildings.
