StreetLight #020 - Parking Lot Lights With Windmill
I thought these were cool from the first time I saw them (& at that time i really didn't pay too much attention to streetlights)
Pic shows 2 different lights/views, and the 'cage' at the bottom of a pole which houses the electrics :)
I think these were MH, but I don't remember for sure since its been some time since I've been to that store at night.
I did some searching and found actual info on this setup:
<Quote from a press release> Urban Wind Farm:
Belmar includes a small, electric power generating urban wind farm to produce electricity to light one of the parking lots. When the lighting is not in use, the power will be added to the Xcel Energy main electrical grid for use elsewhere.
* Fourteen light poles are outfitted with small wind turbines that will collectively generate approximately 400 watts of power at a wind speed of 28 mph.
* Each 13 lb. wind turbine will have a carbon-fiber reinforced composite rotor blade with a diameter of 46 inches that will spin up to 600 revolutions per minute (RPM).
* The turbine bodies change direction with the wind to maximize power output.
* The wind farm has the potential to generate 700-900 kilowatt hours of electric power per month.
