Solar and Wind Powered Street Lights In Tokyo
We just wrote about the new LED streelights in Ann Arbor. Now we find these self-contained streetlights that generate 100% of their power from the sun and the wind. During the day, solar power is stored in a battery at the base of the light pole. At night, they illuminate while continuing to generate power via a small vertical-axis wind turbine. The streetlights, dubbed “seagulls”, were spotted in Tokyo outside the Panasonic Center by Hyperexperience. Here’s a video clip of the wind turbine in action.
