air cars have been developed by MDI (motor development international) luxembourg.

the airpod is one of the many cars that they intend to produce. approximately the same
size of a smart car, it is powered by a tank of compressed air. reaching up to speeds
of 35mph it can travel a distance of 60 miles on one tank. the 4 seater vehicle is controlled
by a joystick rather than a steering wheel. air france and klm airlines will launch a 6 month
trial of the compressed air vehicles in spring 2009.
