Wifi hotspot powered by wind turbine and solar panel

Students at the Rochester Institute of technology have put together this WiFi hotspot that is powered by a wind turbine and a solar panel. It gets its signal through a parabolic antenna pointed at a near by building and repeats it for use in the vicinity. They are using a 30W solar panel, along with a 1/4 horse power 90V DC motor to charge two 6V batteries in series. On a windy day, the turbine has yielded 120W. Something interesting to note is a comment they made about blades. Though the ultimately decided to mimic a commercial design for wind turbines, they found the most efficient to be a single wood prop. Unfortunately, that prop was destroyed.

I lived in st. Louis Park, MN they had plans to put in a city wide solar powered wifi network… The contract was dissolved due to delays in deployment but solar powered wifi is nothing new… a bit of 802.11s would sure be welcome in that kinda node system though.
