This might not be the most practical outdoor light in the world, but what the Firewinder lacks in pedestrian utility it makes up for in sheer engaging awesomeness. Transforming wind into light, the Firewinder is a hanging, wind-powered LED light that can be powered by the smallest breeze. Unlike most wind turbines that spin vertically, the Firewinder spins in a horizontal direction, illuminating its LEDs in a spiraling helix of light. The coolest thing about the Firewinder is that it doesn’t just run on or off, but instead is visibly reactive to subtle changes in the environment. How bright the LEDs glow corresponds directly to how fast the turbine spins, enabling observers to visualize the power of wind.
