There is no zero pollution motor. Something somewhere has to provide the energy to make it go. I guess you could argue that a solar cell car was zero pollution, but even making solar cells creates some pollution.

^^ thanks very much--interesting read; using compressed air as energy storage medium (like a flywheel of sorts). They tout 0 CO2 emissions though (not that CO2's a pollutant) which is completely false--didn't intend to be mean or anything--just get a bit weary of these "ZEV" 's which is not at all correct--the energy has to come from somewhere (in this case, something is burned somewhere to compress the air). I do think we should be using everything we have, though.

I'm sure they have thought about that. The tank is probably encased in a protective 'safe' for lack of a better term, or some other device. It may also be just protected from sides and the top, so that the decompression is directed toward the ground if it is punctured.
There may also be a pressure release valve that is opened when the vehicle senses itself in a severe or specific type of crash, safely releasing the pressure. Would work similar to the sensors used to set off airbags.

I saw one of those little smart cars driving on the busiest highway in Houston one night. I was wondering why all the drivers around were getting pissed off and speeding up to cut her off. I felt like she was gonna die because people with more powerful cars were cutting her off. Then again she was driving in the wrong lane. Not the far left but not as far right as she could have been.
Wouldn't there be a greater risk when getting in an accident?
When crashing a gasoline powered car, the fuel burns slowly, rarely "exploding".
When crashing a car powered on compressed air, what happens when that massive air take ruptures?
Isn't that how you'd get the turbo to work
But seriuosly, just to go to work and back, I'd buy it. That would be awesome. 96 mph and 74 horsepower, thats ok, I'm never in a hurry to get to work anyway
I wonder if the compressed air is "captured" from the combustion chambers of the gas engine? A lot of potential "power" is expelled through the exhaust pipe on conventional engines.
It would be a good commuter car. I wonder why its coming from India? Did we finally outsource all our engineers there?

I don't believe our government would ever let cars like that one become popular. There is too much money in fuel. Gas companies will do whatever they can to keep that from happening.

India is a little country with a hell of a lot of people. It is basically throwing 3 times the amount of the total people in the US into the area of Texas.
They have very poor atmospheric conditions there because of pollution from automobiles. They have low wages and income. Oil prices driven up by the rest of the western world have all but bankrupted those who use fuel for transportation in India.
This is cause for them to develop alternative energy sources for transportation. Sure, you can use electricity such as in cars like that of Tesla Motors: Tesla Motors But...you still need to burn fossil fuels (primarily) to provide enough electricity to run such a vehicle.
Atmosphere is atmosphere. Doesn't matter if it is CO2, O2, He, H, or otherwise...it can be compressed and stored in a tank. So doesn't matter if the air is pure or dirty. That pressure can in turn run gears and provide energy, just like in an air-powered nail gun.

Actually, not so much (at least not so much power good for putting something in motion). Engine functions as a big air pump. If you increase exhaust pressure by attempting to get work out of the exhaust, you make the engine run less efficiently, negating any potential gains. You could conceivably use the thermal energy itself for something useful (electricity, preheating fuel/air when applicable, recovering it to heat something, etc.). Second law of thermo limits the maximum energy of motive energy you can get from the engine. The absolute best you can ever do is the temperature in the hot section minus the temperature of the surroundings (in degrees Kelvin) divided by the the temperature of the hot section. This number is always less than one, and is usually less than one-third. This is also why there are practical limits to the efficiency of all heat engines (including turbines at power plants).

You'll need to burn something to power this car as well. The energy to compress the air has to come from somewhere. It's right now probably fossil fuels (i.e. electric power plants burning fossil fuels); later this may be better--the cleanest cycle would be nuclear breeder to electricity to power cars (compressed air, hydrogen, or electric). India is working on a uranium-thorium cycle reactor.

I didn't say this car wouldn't use fossil fuel. But, it is a heck of a lot better alternative to other cars that use more fuel. 800-1000 miles on 8-9 gallons? That is AWESOME!

Sorry, but you're way wrong there. India is 1,269,346 square miles; Alaska, our biggest state, is only 663,267 sq miles, or about half.And Texas is smaller than Alaska.
