An air car is one that uses alternative fuels such as bio-products such as gasoline-ethanol and other products, in contrast to ordinary fuels on the market. This car has a speed range up to 125 miles mph, and can be taken at least 68th The car may at any gas station, equipped with customized offer is being refueled. The tank can also be charged with the built-in compressor by connecting to a network of electricity for four hours.

The general idea is to use a different method of powering a car engine. In recent years, the drastically increased fuel prices which led to the desire for alternative and cost-effective to power machinery, cars and look for moving objects. This has to explore other possibilities, which led them to see in these difficult economic times. Environmental concerns have also been forced to take the energy further and aims to reduce the release of harmful gases in the atmosphere, forcing the governments concerned to invest in other means of energy production.

In particular, the air car equipped with an engine that is emissions free piston. The piston is driven by compressed air. French Guy Negro was the first engineer to invent environmentally friendly the car. The energy from the heating of the ambient air in the cold storage tank is compressed. The only problem is the cold air, which can under-150C and the cold air is to be transformed as a product, cooling the car to be used. The delivery of air through a fuel injection system. Ammonia is running as an alternative fuel for the engine for this car, and this is because of its ability to be converted easily to in light situations without operating hazardous products of combustion environments. The gas is easily accessible and can be done by electricity, can and should easily transported from one place to another in fixed quantities and harmful products from the steam and nitrogen.

In 1908 to 1927, was the Ford Model T, the first car, ethanol (alternative) method of using air as fuel. Methanol can also be used separately or in combination with ethanol for motor power. They can be obtained from natural gas and petroleum. However, ethanol is more reliable because their availability. It can even be produced from starch or sugar in agricultural products like grain cane sugar, lactose, and the general culture. It is naturally produced when yeast reacts with sugar solution, even from overripe fruit. In addition, methanol is considered toxic. Other products have been tested are butane, which can be obtained from the fermentation of plants. Regardless of all the tests, ethanol is superior to the others. Obviously, ethanol has some negative effects, it decomposes easily some of the rubber compounds are used in the gaskets and fuel lines. It may also be impossible for the vehicle to be launched with a high percentage of ethanol fuel, because ethanol is less volatile than petrol, more than in the cold season. Electrical conductivity of ethanol has raised concerns it may corrode fuel pumps at the beginning and the tank sensors.
