The LumiWall: Solar Glass That Lights Up At Night

Imagine a roof that looks like shaded glass by day, but by evening is transformed into an illuminated array of white LEDs. Sharp's LumiWall promises to do this, and it's powered entirely by thin-film solar panels inside the glass. It's like a transparent battery that gets charged by the sun. LumiWalls won’t really generate much electricity for your house — the aim here is to create an aesthetically-pleasing, self-contained illumination device. They will be available in 2007 according to Sharp. :: Sharp via The Green Guy
