Introduction
 Gasoline pollutes the air that is becoming increasingly unhealthy to breathe, and people no longer want to pay the high prices that oil companies are charging for it
 The search is on, but what will this fuel of the future be? Automobile manufacturers are turning to greener energy sources like batteries.
 Air!! At first glance, the idea of running a car on air seems almost too good to be true.
 With the rising cost of fuel, this development is timely in the search for sustainable energy.
 The laws of physics dictate that gases will fill any given space.
 The easiest way to see this in action is to inflate a balloon.
The history of CAV
 For half a century, the air-powered locomotive was a serious contender for the top spot in transportation because of its obvious advantages: simplicity, safety, economy, and cleanliness.
 Air engines were commercially available and used routinely, first as metropolitan street transit and later for haulage in mines.

 The history of CAV
 Terry Miller, the Father of the Modern Air Car Movement.
 In 1979, Terry Miller set out to design a spring-powered car and determined that compressed air, being a spring that doesn't break or wear out, was the perfect energy-storing medium.
Angelo Di Pietro's Rotary Positive Displacement Air Engine
 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.

 Guy Negre And MDI
 Currently a French inventor named Guy Negre is building an organization to market his air car designs in several countries.
 Mr. Negre holds patents on his unique air engine in several countries.
 Plans are underway to build air car factories in Mexico, South Africa, Spain and other countries.
 MDI's Taxi
Working Principle:
 The laws of physics dictate that uncont¬ained gases will¬ fill any given space. The easiest way to see this in action is to inflate a balloon.
 Compressing a gas into a small space is a way to store energy. When the gas expands again, that energy is released to do work.
 Compressed Air is used as a fuel. When this air is allowed to expand at atmospheric conditions its volume is increased many times this energy produced is used to drive an Air Powered Car
 Even every Formula One engine starts with a shot of compressed-air as an Energy-Booster.
Refueling:
 The air tanks could be refilled in one of two ways i.e.
1. Either by using a household electrical source, it takes about four hours to refill the compressed air tanks. Tanks are refilled by plugging the car into a mains socket to feed the motor-alternator which compresses the air with the motor compressor.
2. Or by means of a special system, i.e. a rapid three-minute recharge is possible, using a high-pressure air pump at air stations. These methods consume electrical energy which loads the power stations also leading to increase pollution since power stations depend on fossil fuels for power generation. Hence some alternative sources of refueling which can be used in future are; wind energy, hydraulic systems, fuel cells, photovoltaics etc can be used.
Details of Compressed Air Vehicle (CAV)
Parts used in CAV:
1. Air Motor.
2. Compressed Air Tank (Tank cum Compressor).
3. Steering Mechanism.
4. Chassis.
5. Axles.
6. Air pressure regulators.
1. Air Motor
Description:
 A pneumatic(Air) motor is a machine which converts potential energy in the form of compressed air into mechanical work.
 Air motor converts the compressed air to mechanical work either linear or rotary motion.
 Linear motion can come from either a piston actuator, while rotary motion is supplied by either a vane type air motor or piston air motor.
 Air motors have found widespread success in the hand-held tool industry and automobiles as well.
 However, Air motors must overcome efficiency deficiencies before being seen as a viable option in the automobile sector.
2. The Compressed Air Tank
 Compressed Air Energy Storage (CAES) is a way to store energy generated at one time for use at another time.
 The compressed air vehicle contain many components but the most important component is air storage tank which is use to store compressed air.
 The compressed air vehicle contain many components but the most important component is air storage tank which is use to store compressed air.
Compressed Air Tank
 Our Design : Air Motor & Compressor
1. Steering mechanism:
 The most conventional steering arrangement is to turn the front wheels using a hand–operated steering wheel which is positioned in front of the driver, to allow it to turn from a straight line.
 Hence we have selected simple steering mechanism of Ackermann's type.
2. The Compressed Air Tank
 Compressed Air Energy Storage (CAES) is a way to store energy generated at one time for use at another time.
 The compressed air tank is a M.S tank, which can store up to 90 cubic meters of air compressed to 150 psi.
 Our Design : Air Motor & Compressor
3. The Chassis:
 A frame is the main structure of an automobile chassis.
 All other components fasten to it.
4. Steering mechanism:
 The most conventional steering arrangement is to turn the front wheels using a hand–operated steering wheel which is positioned in front of the driver, to allow it to turn from a straight line.

Conclusion :
 The air car is a clean, easy to drive, high performance car.
 The end product is a light weight vehicle that can reach speeds up to 220 km/h r.
 Does not pollute like twentieth century vehicles and does not take a lifetime to pay off.
 Fast recharge time
 Long storage lifetime (electric vehicle batteries have a limited useful number of cycles, and sometimes a limited calendar lifetime, irrespective of use)
 Potentially lower initial cost than battery electric vehicles when mass produced.
