Pneumatic traction systems have already been used since Denise Papín, who apparently already had the idea of using compressed air in cars. Currently in Uruguay and India with Armando Miguel Regusci Campomar and the French inventor Guy Negre respectively, they make use of this energy and mention high efficiency in their compressed air motors. In this vein and in order to continue research with this energy, explore non-polluting alternative energies and their efficiency, a Pneumatic-Mechanical traction system is proposed in this research, in a mobile of our own manufacture. The system works under two principles of elementary physics; Pascal's pneumatic energy and Tesla's alternating pneumatic energy that is, alternating pneumatic energy, their efficiency is tested with the energy of the compressed air tank and the displacement energy of the mobile
