Performance of cars

This is concept created by me. In this speed of car is increased by using air striking on the front of car. I have designed the vehicle in which there are blades fitted on the back axle. There are two hollow tubes joined with blades which opens in front of car at the other end. Now when the car is moving with some speed the air enters in tubes and strikes the blades
Now the blades will rotate with more speed which will also rotate the axle and wheels with more speed hence the vehicle. I hope you will like my idea .if there is mistake in the concept then please inform me so that I will work more on the project.

Have you considered that the air entering those tubes will tend to increase in pressure, thus tending to slow down that car, before reaching the blades at the rear? The laws of conservation of energy mean you don't get something for nothing.

the slowdown of car will be overcome by speed of car and also the tube will be designed in that way .

??? By increasing the throttle, and consuming MORE petrol? Does that 'tube' also feed the compressed air into a gas turbine combustion chamber which will consume kerosene?
