The TV Show Beyond Tomorrow in one of their episodes had 2 stories about air powered vehicles. I personally want to get 1 or 2 of these motors to put in my current minivan if they are powerful enough. It would be something great to mix with an electric air compressor and a small cartop vwat and 1 or 2 bateries in a car or vinivan. I have yet to contact the companies to see how expensive the motors would be.
