A question for scientists out there. Is it possible to generate?

Question

energy by way of wind force while driving a car? Could you somehow use small wid turbines to run your engine after enough speed.? Is there any one trying to do this sort of thing?

Answer 1

It's possible to generate power this way, but not nearly enough power to run the whole automobile at that speed (laws of thermodynamics and all).

Your idea is actually used on some commercial airplanes in case of emergency. A small auxiliary generator is popped out the bottom of the airplane, near the back, in case the electrical or hydraulic power fails. It looks like a minature engine, but it is nothing more than a fan connected to a generator. This generator supplies enough power to keep instruments and hydraulic pumps running (but not enough power to keep the main engines flying).

Answer 2

Any kinetic energy a car has is a result of burning fuel. Therefore, any energy you get from your wind turbine was originally in the fuel. Thus your wind turbine is merely one way of converting engine power into whatever. It's easier just to use an alternator and an electric wire.

Answer 3

Skippy say no. The First Law of Thermodynamics says that energy under normal conditions cannot be created or destroyed, simply transformed from one type of energy to another. Thus a chemical reaction such as lighting a match does not create new energy but only converts one type of energy to another.
Skippy say energy used to move car and make wind turn turbines wouldnt create any new energy and couldnt effeciently run car.
Skippy say there is no such thing as free energy or perpetual motion machines

Answer 4

Any energy generated in this method would be more than offset by the decrease in gas milage as a result of the increased wind resistance of the turbines.

Answer 5

It may be possible to generate a minimal amount of power from such a system but certainly not enough to power the car's motion as a whole. You *might* be able to power, say, a small radio in this manner.

Edit: BTW, this is something better left for the 'Engineering' board, IMO
