INTRODUCTION

Fossil fuels, which meet most of the worldsdemand are being depleted rapidly.

Their combustion products are causing

problems like global warming, green houseeffect, acid rain, ozone depletion..

These factors are resulting in development of

alternative fuels.One possible alternative is the air powered

vehicle.

PRINCIPLE We all know that the air fills up any given

space.

The easiest way to see this action is to inflate

a balloon.

The elastic skin of the balloon holds the airtightly inside, but the moment you use a pin

to create a hole in the balloon's surface, the

air expands outward with so much energy that

the balloon explodes.

Advantages Much like electrical vehicles, air powered

vehicles would ultimately be powered throughthe electrical grid. This makes it easier to focuson reducing pollution from one source, as

opposed to the millions of vehicles on theroad.

Transportation of the fuel would not berequired due to drawing power off the

electrical grid. This presents significant costbenefits. Pollution created during fueltransportation would be eliminated.

Compressed air technology reduces the cost ofvehicle production by about 20%, because thereis no need to build a cooling system, fuel tank,

Ignition Systems or silencers. Air, on its own, is non-flammable.

The mechanical design of the engine is simpleand robust.

Low manufacture and maintenance costs as wellas easy maintenance.

Compressed-air tanks can be disposed of or

recycled with less pollution than batteries. Compressed-air vehicles are unconstrained by the

degradation problems associated with currentbattery systems.


10/17

The tank may be able to be refilled more often

and in less time than batteries can be

recharged, with re-fueling rates comparable to

liquid fuels.

The price of fueling air-powered vehicles will

be significantly cheaper than current fuels.

The infrastructure for refilling will not be such

a problem, since the air can be filled up even

in puncture shops.
