This is just another example of micro-green technology in an entirely necessary and functional setting.  The video shows a streetlight running on both wind and solar in front of Panasonic Center in Tokyo.  In addition to the helix turbine and butterfly solar panels, there’s a high-efficiency light bulb and battery for capturing energy during the day (to be used at night).  Someone tell me why we don’t see more any of this in the U.S.?  Via EcoGeek.
