Engineair’s Ultra-Efficient Rotary Compressed-Air Motor

Imagine a vehicle with nothing under the hood (or bonnet), no gearbox, no transmission, no carburetor or other fuel feeds. Yet it converts virtually all the energy fed to its motors into actual motion. With the elegance of absolute simplicity, this concept makes traditional internal-combustion cars look like the Rube-Goldberg contraptions they are: using way too many parts and stages to do what is really a simple task.
