Air Powered Car Finds Home in India; Tata Motors



January 27, 2008 – Comments (5) | RELATED TICKERS: TTM

"Whether this tech will ever make it to North America (whose futures seem firmly tied up in electric and hydrogen-powered vehicles) is debatable. Either way, with environmental concerns over India’s fast-growing vehicle population (especially in light of the newly announced $2,500 car), any alternative-energy technology with impact potential would be welcomed."

There are a couple of issues with an air-powered car that the report didn't even touch on:

1) Where do you get the compressed air?  Compressed air is just a method of storing energy.  Unless you can find a way to compress air without polluting, it isn't non-polluting, is it?

2) The laws of thermodynamics make compressed air an inefficient way of storing energy.  Anyone who has ever used pneumatic tools knows that air gets really hot during the compression process and really cool when it is decompressed.  Ever spray an aerosol can long enough that it gets cold?

This means that a lot of energy is wasted in the form of heat when the air is compressed, and since cold air is more dense, when you use compressed air to power a piston, you won't get as much expansion and lose energy there, too.

It's a nice idea, but the process is fundamentally too inefficient to be practical.

Nice find! Sure, the technology is still young. But it's great to know that Tata motors has decided to pursue this technology. Apparently they are going to release a car into the market in the summer of 2008! 

It seems you can fill it up at a station in a couple of minutes, or at home in a few hours. This would only cost a couple of dollars per refill! The cheapest car would cost $5000  or so.

Tata motors promised a car for $2500 and they kept their promise. They will also keep their promise for the air-fueled-car.

 Of course the oil industry/lobby is going to fight this with all their (financial) power!

American manufacturing has to come up with a big, big lobby plan to fight this off.

It is really sad to see how America's car industry has completely missed the chance to develop a car fueled by alternative energy. This is probably the reason, why their stocks are tanking for the long term. I have read that their latest attempt to finally increase earnings is a SUV equipped with every technical gadget you can imagine. The reason for this is that sales trends have pointed to this. Of course these are all cars bought with a leasing plan...

I say "enough" to the oil industry and thumbs up for innovative entrepreneurs. i would so much prefer to own stocks of innovative entrepreneurs than the oil patch.

BTW, maybe it's a sign of the times that it was a socialist country like France which encouraged the development of this technology... Furthermore, a company from a developing country has sensed the future trend...
