self rechargeable car

My idea is to put wind tunnels within the cars frame so when the car is driving forward it will send wind down the tunnels and hit fans that will charge the battery of the electric car. This idea might not solve the problem of the battery going dead but will prolong the drive time of the electric vehicle. City mileage might not improve that much but on the open road it will charge the battery a great deal.

If you put the fans/turbines near the radiator section of the grill, you could avoid any extra resistance while serving another purpose to recharge the battery while moving.

You would create resistance with the wind turbines making it take more power to drive at that speed canceling out any gains from the wind.
