These pretty little LED lights were originally battery powered, but now run on solar power.  During the day they absorb energy from the sun and save it, then light at the hint of a breeze at night.  Turned on by wind and powered by the sun…pretty cool.  Unfortunately not for sale yet, but I’m going to keep an eye out for them in the future.

Here are more details, courtesy of Inhabitat:

“The light is composed of a glass, bell-shaped, vessel, that holds the LED light, circuitry, and solar panel. Wax holds the electronics inside the glass vessel and disperses the emitting light. Paper is suspended from the center of the circuitry, and as the strip of paper is blown, the light turns on. The light will burn depending on the weather that day – more sun charges the battery longer and stronger winds keep it on.”
