Center divide windmill.

Windmill that rotate by the gushing wind from the passing car.

Ever felt how your car shakes when a speedy truck passes by you in the next lane. Which got me thinking it would be a good idea to install windmill (Vertical type, not the fan type) in the center divide of a freeway. The trucks and cars will keep them busy and California gets more power.

       Too bad all those windmills will be useless when aerodynamics improves.

       Hey, I already saw this thing in Popular Mechanics magazine about 5 yrs ago or so, it seemed a great idea then and a great idea now, why has not been baked?   

       A croissant for you!!

       Great idea indeed.   

       Maybe not implemented simply because our highway construction industry does not generally draw the most innovative people into its employ?   

       And, it may be a safety issue. The force of wind you'll get from a passing truck is much much stronger when you're close. It may not have any balance point trading off acceptable safety & economy.

       I think the problem is the wind energy supplied, it is too pulsed. It is basically a short 60mph gust. Also if it is too close to the car, it will actually mess with the cars aerodynamics.
