The Roy J Meyers Compressed Air car of 1932. Of course Mr. Meyers was proclaimed a fraudster. Smart people stated that this vehicle will not function because it is based on a perpetual-motion, which we all know is impossible.
Air compressors have made life easier for people on countless fronts since the early days of automotive assembly. As technologies advanced, productions along assembly lines sped up as cars became cheaper and easier to produce, which allowed automakers to sell their vehicles to consumers at lower prices.
