# Question about Wind Powered Cars

 Posts: 12,788 Add as FriendChallenge to a DebateSend a Message 8/18/2012 2:45:10 PMPosted: 5 years agoWould it be possible to create a car with small flaps on the bumper and the side mirror which would spin when subjected to wind- which would be all the time since the car is in motion to generate energy for it to move? The initial energy to start moving the car would be from some kind of fuel but the energy to keep it moving would come from its own motion.Would this be possible/feasible?"Easy is the descent to Avernus, for the door to the Underworld lies upon both day and night. But to retrace your steps and return to the breezes above- that's the task, that's the toil."

You have to increase the drag to put on those fans, and that takes more energy.Sorry, there really isn't any free energy to be had.twocupcakes: 15 = 13
