Driving Under Presure

BBC News reports that a French company has developed a car that runs on compressed air, will be produced by India's Tata Motors and it may be on sale in Europe and India by year end. More details here, but essentially a fill up (recharge? pressurization?) will cost about $3 for about a 125 mile range. Perfect for a city car or a second car for those of us in the suburbs. Also noteworthy is that its exhaust is non-polluting.
