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.
