When does a streetlight stop becoming something ordinary and turn into a self-sustaining work of art? Apparently, once it finds its way to Japan. Outside the Panasonic Center in Tokyo, one is greeted with several streetlights that incorporate both solar and wind energy systems. The design is called a ‘Seagull’ and takes advantage of light during the day to store energy for night; while producing electricity to push back into the grid thanks to the wind. The vertical turbine on this pole doesn’t appear to require too much wind to turn. No idea what the payback on this might be, but it’s certainly cool to see it in motion.
