A Pneumatically Propelled Peoplemover !

Aeromovel has created an air powered train for urban applications that is smooth, quiet, efficient and zero emissions. Lightweight, aerodynamic and engine-less trains are mounted on axle-less steel wheels and secured to the track. Sails are then mounted to the bottom of the train. The vehicle is driven by a pneumatic propulsion system which converts electrical power into air flow and transmits thrust directly to the vehicle without gears or intervening electric circuits.

Wouldn't that be cool if we could generate the electricity to run these from solar, hydro or wind? Awesome! Super Efficient and innovative, I dig it!
