New Dawn in Automobile Industry: Air and Electric powered cars.

Automobiles are self-propelled vehicles used for transportation. History of automobiles date back to the 15^th century, when interaction between Portuguese and China brought about advancement in technologies. By 1600s steamed powered engines models have been developed, but the first full sized steam powered engine automobile was developed by Nicolas Joseph Cugnot. Thirty-eight years later Francois Issac de Rivaz designed the first car powered by an internal combustion engine fueled by hydrogen and finally in 1886 the first petrol or gasoline powered automobile the Benz Patent-Motor was invented by Karl Benz.

With rapid progress achieved in the 20^th century and lots of innovations in the 21^st century, electric and air powered were invented to minimize the social and economic costs of using gasoline which has become major problems in our 21^st century urban centers.

AIR POWERED CARS

A compressed-air vehicle (CAV) is powered by an air engine, using compressed air, which is stored in a tank. Instead of mixing fuel with air and burning it in the engine to drive pistons with hot expanding gases; compressed-air vehicles use the expansion of compressed air to drive their pistons.

Air powered engines were first built during a period of experimental daily use in metropolitan street transit during 1880s and 1890s by companies organized by investors and air car advocates such as General Herman Haupt.

Post World War II, the air engine development went down as a result of great development in the crude oil sector, but due to oil shortages in the 1970s, air powered cars gained attention again and a few companies started showing interest.

As a result of the rekindled interest there came different designs for the air powered automobiles; conventional, hybrid, closed cycle, and free range air cars, as well as conversions for existing engines.
