The sunlight-window relationship is a simple one: during the day the former passes through the latter, giving us interior light. But Australian designer Damien Savio's Lightway is a window that can conceivably extend that relationship into a 24-hour affair.

The Lightway--details of which are still proprietary--works by absorbing sunlight during the day, storing it in a battery, and giving that light off at night. The time ratio is quite good--four hours of sunshine will give you six hours of 60-watt shine. Savio went with louvers rather than straight glass for his first model, because the individual louvers can be removed and used like ambient flashlights. The OLED-loaded device has been nominated for the Australian Design Awards-Dyson Student Award.

"Whenever I do a design I just want to do something different and something that stands out," says Savio. "I like that with this, you don't even know it's a light until it's on."
