Another Wind and Solar Powered Streetlight
by Lloyd Alter, Toronto on 02. 7.07
When there isn't sun there is often wind, so it makes sense to use them both. Here is another version of a combined solar/wind powered streetlight, perhaps not as elegant as Justin's Canadian vertical axis unit, this Chinese fixture has a 400 watt turbine, 200 watts of solar, batteries and controls with a six day reserve, powering a 200 bulb 30 watt LED array.
"intended for permanent installations and can be located in the remotest of sites since no mains services are required saving on installation costs, inconvenience and time. The whole system is virtually maintenance free and there are NO daily running costs- the power is completely free and clean." ::Duxlite
Here is a whole street of them.

Fabulous idea--and I hope it does work, however the solar driveway lights I've seen peter out after like a year. The batteries don't last long in the constant charge-discharge cycling they do. And that ends up being even less efficient, because you have to replace them.
This is closer to my idea...
Is providing easy light to remote areas really something we want? I'm sure that using a solar and/or wind farm to generate the power en mass is more efficient, although this would continue to run during an outage. Seems like all this does is promote light pollution to areas previously unpollutable.
Hmmm, You have to concider that some people might wanna climb up and snatch them solar panels for them selves...raping the poor street lamps. I suggest, constantly run a high voltage shock through the whole thing as a self defence mechanism against raiders.
I would like to congratulate you for this efficient and environment friendly system for street lighting, and I have some inquiries:
How much the cost in US $ per mast (the mast icludes wind, solar, fixture with lamp and any other equipment).
What is the approperiate distance between masts in the high ways?.
What is the approperiate distance between masts in the streets of residential areas?.
Best regards
Just a hunch but I bet they have better batteries than your solar powered driveway lights and with a 6 day power surplus they probably wont dip too low into the battery's capacity and that'll help life also.
Hi, we sell a lot of log cabins to remote areas, http://gardeners-world.net/cata_show.asp?id=63 , but we really would love to find a suitable green power source that can be set up for them, similar to the above, does anyone know of such a product in the uk ?
The wind/solar power streetlight is best
we should initiate and popularization these products to be able in ours side as soon as possible. it's very important for research and develop of this product in China,and launch into great a bankroll for it.it's specialty in this domain that shanghai century energy conservation trade co.,ltd
