Firewinder!

“This virtual wind turbine has 14 LEDs attached to it and as the wind blows, the LEDs illuminate and optically blend into one another to create an outdoor light. The turbine needs winds faster than 3 mph, but higher speeds means brighter lights. While not bright enough to light the surrounding area to guide passers-by, it definitely is a hip way to add a pinch of renewable snaz to an outdoor evening party.”
