The compressed air car is a much desired development in the search for an alternative cleaner, non-polluting form of motivating power that can be used in transportation. For the past 150 years the IC Piston engine, working on the Otto cycle and first invented in 1866 by Nicholaus Otto, has been the mainstay of personal and commercial road transport. Yet with all the billions of dollars spent on trying to improve the performance of the IC Piston engine, every working sequence of the engine being examined and tested with the latest computer technology and simulations, by millions of people around the world, it is amply clear that if a solution is to be found for a more efficient engine, it wonbe based on IC piston technology. Even with all the 21st. Century innovations and improvements, such as MPFI, double overhead cams, multiple exhaust and inlet valves etc., the IC piston engine efficiency remains at 20%!
Think of it, an amazing and unacceptable 80% of the energy in the fuel used is wasted, by comparison, rockets and jets have an efficiency of 70% and better or are more than two and a half times as efficient as piston engine cars, they are also, relatively, pollution free. Unfortunately, both turbines and rockets require or have required until this date, continuous combustion to deliver this order of efficiency. When used in road transport they are therefore very fuel inefficient using about 8
