Between 600 and 700 million vehicles exist on the globe (there is no accurate count) and each year another 60 million passenger vehicles are added to the total. Every minute each of those vehicles is in motion, enough heat to warm a large house in a cold climate has to be removed from the engine in order to keep it moving. Today's automobiles convert only one-third of the energy produced from combustion into mechanical energy to drive the car forward. A third is released to the atmosphere through the exhaust and the other third is released as heat energy that is absorbed by the engine. Without a system to remove that heat, vehicles would be unable to function. The heat generated within the engine would cause the pistons and other components to expand and to jam, seizing up the engine, and stopping the car from moving. Without the engine cooling system, of which a fan is an integral part, a car can go nowhere.

PaxAuto is an engineering and intellectual property licensing company that has been granted exclusive global rights to air movement technologies for automotive applications developed by PAX Scientific, Inc., of San Rafael, California. The company addresses the automotive engine cooling and climate control sectors with patented fan technologies that reduce noise and energy use while improving airflow in automotive systems.
