This document describes an air-powered car developed by Guy Negre as an alternative fuel vehicle that reduces pollution. It consists of air tanks that store compressed air, a chassis made of aluminum rods, air filters to clean the air, and a 1200cc engine that runs on compressed air. The car is lightweight, produces less emissions than gasoline or electric cars, and can supplement its air fuel with gasoline when traveling over 60 kph. However, it requires electricity to compress the air and makes noise during operation. Overall, the document argues that air-powered cars provide a practical solution to urban pollution problems.
