ABSTRACT
Gasoline, which has been the mainsourceoffuelforthe historyofcars,is
becoming moreand moreexpensiveandimpractical (especiallyfrom an
environmentalstandpoint).
Thesefactorsareleadingcarmanufacturers todevelopcarsfueled byalternativeenergies.

INTRODUCTION
Due toincreasingamount ofpollution,crisisoffuelandincreasingcost offuel weneed to thinkabout alternativeforfuel. Somealternativesforfuel
aresolarenergy, hydrogen, bio-gasandcompressednaturalgas.
Airpoweredcarsare zeropollutioncars which willusecompressedairor
nitrogengasinsteadofgasolinefuels. It willnot onlyreduce thecost of
fuel but willalsoenvironment friendlyandit isarenewablesourceunlike
gasoline.

MDIsvehicle's havefibreglass bodies which makes them light,silent
urbancar. Thecar's bodyis tubular,light weight,andis held togetherusing
aerospace technology.
Thevehiclesdonot havenormalspeedgauges. Instead, they will havea
smallcomputerscreen that shows thespeedandenginerevolutions.

FUEL AND RECHARGING:
Airtanks madeofcarbonfiberarefixed to theundersideofthevehiclecan
holdabout 79 gallons (300 liters) ofair. Thiscompressedaircanrun thecar
forup to 124 miles (200 km) at a topspeedof60 milesperhour(96.5 kph).
Alternativeenergiessuch assolarpowerorwindpowerorevennuclear
powercould beused topowerthecompressorsifavailable, toresult in zero
carbonemissions.

FUEL COST:Thepriceofafull tankofairwould beabout 1.50 euros (86.35 rupees)
MILEAGE:Thecarwith full tankofaircanrunuptoabout 300 kilometers (200
kilometersin trafficareas).

OIL REQUIREMENT:
Thecar's motordoesrequireasmallamount ofoil. About .8liters worth that thedriverwill have tochange just at every31,000 miles (50,000 km).

ADVANTAGES OVERGASOLINE FUELS
Cost ofgasolineisincreasingday byday; moreoverit isnot environment
friendly.
Gasolinefuelisalsonot arenewablesource,so that it willeventuallyrun
out.
Insomecaseofaccidents thereisalsoachanceofexplosion.

WORKING BYNITROGENGAS
(CRYOGENIC ENGINE)
Anotherversionofanair-poweredcaris beingdeveloped by
researchersat the UniversityofWashingtonusing theconcept ofa
steam engine,except thereisnocombustion.
The Washingtonresearchersuseliquid nitrogen as thepropellant for
theirLN2000 prototypeaircar.

Theresearchersdecided tousenitrogen becauseofitsabundancein theatmosphere (nitrogen makesupabout 78 percent ofthe Earth's
atmosphere) and theavailabilityofliquidnitrogen.

However, becausealiquidnitrogen-propelledcarwill belighter, theresearchers thinkthat a 60-gallon (227 liters) tankwillgive the LN2000
apotentialrangeofabout 200 miles (321.8 km).

CONCLUSION
With gaspricessoaringover thepast years,it might not belong before
many motorists turn tovehiclespowered byalternativefuels.
Although air-poweredvehiclesarestill behind theirgasoline
counterparts whenit comes topowerandperformance, theycost less to
operateandarearguably moreenvironment friendly, which makes them
attractiveas thefutureofhighway transportation.
