Turning Highways into Wind Farms

John Davis

Interesting concept was posted on the web site Engadget.com.

Highway windmill #1Some student designs are proposing that windmills, such as the one shown on the left, would be built above the nation’s highways. As cars whooshed by, the wind would turn the turbines and produce electricity. Proponents say its a way to produce green energy, even when the original source is not so green.

Another idea would be to have median barriers with wind turbines inside them (pictured below).

Some drawbacks to that, however, might be safety concerns as to whether the barriers could hold up to the rigors of traffic and if they could keep someone from smashing into the oncoming lanes of vehicles.

Both are interesting ideas and prompted a lot of comments at the Engadget.com web site.
