Abstract: Systems and methods effective to reduce a drag coefficient in a vehicle are described. A system methods may receive first air directed towards an air intake structure at a first speed. The air intake structure may transform the first air into second air of a second speed. The system may direct the second air from the air intake structure to a tunnel structure. The tunnel structure may include an entrance and an exit, where a cross-sectional area of the entrance may be less than a cross-sectional area of the exit. The tunnel structure may expand the second air into expanded air. A third speed of the expanded air may be less than the second speed of the second air. The system may create a second drag coefficient, where the second drag coefficient may be less than the first drag coefficient.

Abstract: A system comprising an air intake structure, a tunnel structure, and an energy generation device is described. The air intake structure may include a first entrance and a first exit. The air intake structure may receive air directed towards the first entrance. A size difference between the first entrance and the first exit may cause a compression of the received air into first compressed air. The tunnel structure may include a second entrance and a second exit. The tunnel structure may receive the first compressed air. A size difference between the second entrance and the second exit may cause a compression of the first compressed air into second compressed air. The energy generation device may receive the second compressed air, and may transform a portion of the second compressed air into energy. The system may further include elements effective to facilitate cooling of components of a vehicle.
