"Powered by the sun, moved by the wind"
"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." (artigo publicado em Inhabitat, ver mais aqui)
