"Firewinder is a wind powered light that’s both environmentally friendly and beautiful. Wind from any direction spins a small turbine that lights up LED’s along it’s edge. The device “breathes” with the changing winds, increasing it’s intensity from a dim glow to a brilliant light as speeds increase. The shape of the Firewinder was inspired by naturally occurring spirals and can be easily disassembled for recycling."
