Abstract: The inventive concept is directed to a “COMPEL” system. The word compel is an acronym of the words “compressed air and electricity”. The compel system is a system of mechanical devices aligned together to propel a vehicle without employing any fossil fuel and creating very little or no detectable pollution. The motion source is a single electric engine that drives the vehicle by way of a transmission. The source/s for producing the electricity originate in two different manners. One source is of the motion of the vehicle itself and responsible for the action of the second source. Conversely, the second source provides the energy to propel the vehicle, Thus, each source is generally dependent upon the other. However, the holding reserve capacity of the fuel tank allows for the compressed air engine source to mobilize the vehicle from a dead stop and thereby re-engage the other generating source/s. The other energy generating sources are elements driven by the axle of the vehicle.
