Brief Description:
This invention is an brilliant way to recycle otherwise wasted energy created by moving vehicles on highway. High velocity vehicles use a lot
of energy to push air out of  their. Those energy become wind draft can be recycled by this invention or otherwise go wasted.

Purpose of the Invention:
To recycle otherwise wasted energy and to generate electrical power.

Problem[s] the Invention Solves:
Most wind energy focus on collect natural wind power. They often face the problem weather the wind speed is too low or too high. At middle
of highway, there is wind draft when there is traffic. Natural wind blows at one direction; at middle of highway, wind blow at two opposite
directions. This design use guiding well to separate them and guide the wind draft to turbine house.

Detailed Description of the Invention:
A serious of vertical axle, bi-directional wind turbines sit at middle of highway to recycle wind draft energy from both way of traffic. These
wind turbines have wind tunnels on both side of their housing to collect wind energy from both side of traffic. And there are guiding wall in
between two wind turbines to guide wind draft to wind turbine.
Highway Wind power
The average U.S. Vehicle is driven 11,900 miles per year according to
the Energy Information Administration.

Gallons are converted to CO2 using 25.3371 lbs CO2/gallon gas -
19.2898 lbs of CO2/gallon in direct emissions and 6.0473 lbs of
CO2/gallon in upstream CO2 emissions - from the Greenhouse
Gases, Regulated Emissions, and Energy Use in Transportation
(GREET) model.  (2000lb = 1 ton)

Study showed that the US uses 120 billion gallons (450 billion liters)
of gasoline every year. The Nationwide average retail price for all
types of gasoline as of Monday, June 5, 2007 rose 2.4 cents per
gallon for the week,  according to the U.S. Energy Information
Administration, to $2.937. That’s $ 360 billion dollars spending every
year around the nation.

5.3% of those energy is used to just push air out of vehicle's way.

Gas mileage data are from the U.S. Environmental Protection Agency
and the U.S. Energy Information Administration.


I measured raw wind speed on highway from side of highway,  
(roughly 5 meters from moving vehicles) the wind speed range from
3-5mph, more than enough to push a wind turbine. With some
special wind guiding wall design, we should be able to collect more
wind energy.
