Angelo Di Pietro
The Di Pietro motor concept is based on a rotary piston. Different from existing rotary engines, the Di Pietro motor uses a simple cylindrical rotary piston (shaft driver) which rolls, without any friction, inside the cylindrical stator. The space between stator and rotor is divided in 6 expansion chambers by pivoting dividers. These dividers follow the motion of the shaft driver as it rolls around the stator wall. The motor shown is effectively a 6 cylinder expansion motor.
The cylindrical shaft driver, forced by the air pressure on its outer wall, moves eccentrically, thereby driving the motor shaft by means of two rolling elements (not shown) mounted on bearings on the shaft. The rolling motion of the shaft driver inside the stator is cushioned by a thin air film. Timing and duration of the air inlet and exhaust is governed by a slotted timer which is mounted on the output shaft and rotates with the same speed as the motor.
Variation of performance parameters of the motor is easily achieved by varying the time during which the air is allowed to enter the chamber: A longer air inlet period allows more air to flow into the chamber and therefore results in more torque. A shorter inlet period will limit the air supply and allows the air in the chamber to perform expansion work at a much higher efficiency. In this way compressed air (energy) consumption can be exchanged for higher torque and power output depending on the requirements of the application.
Motor speed and torque are simply controlled by throttling the amount or pressure of air into the motor. The Di Pietro motor gives instant torque at zero RPM and can be precisely controlled to give soft start and acceleration control.

"There is no other motor as good as ours, years of research and analysing other motors around the world gave me the confidence and obligation to say so. Obligation in the sense that people have been waiting for ages in relation to efficiency in order to take care of our environmental situation.
100% more efficiency than our competitor is a very serious claim and should not be confused with some kind of publicity stunt were the interest is purely to try and make money out of some ridiculous claim.
The invention has a long list of important improvements over other motors.
The concept has the capability to change the method we use for transportation, apart from the benefits of energy saving in stationary applications.
We have verification of its performance
We have patents issued
It has outstanding efficiency
It has constant high torque
It has low parts count
It has low number of moving parts
It is compact and light
It has virtually no friction
It has virtually no vibration
It has smooth speed control characteristics
Only 1 PSI of pressure is needed to overcame the friction

Angelo Di Pietro has developed the “world’s first commercially-viable motor vehicle powered by compressed air.” His design uses “compressed air to drive a rotary engine, abandoning the pistons and cylinders seen in regular designs.” Videos here.
"The vehicle being tested in Melbourne has reached 50 kilometres an hour (31 miles an hour) in the workshop and had proved more efficient than battery-powered golf carts "
