The Di Pietro Engine is a compact, inexpensive but very efficient motor that is powered by compressed air. It has successfully powered a range of vehicles from cars to forklifts. It produces no polluting emissions. Compressed air can be refilled in minutes compared with hours for batteries. Compressed air tanks are made of steel or carbon fibre whereas batteries require heavy metal, rare earth and are a source of harm to the environment.
