The Air Car Nears Completion
torok writes "According to an article on Gizmag, Tata, India's largest automotive manufacturer, has developed a car that runs on compressed air. It costs less than $3 USD to fill a tank on which it can run for 200 to 300km. The car will cost about USD $7,300 and has a top speed of 68mph. About once every 50,000 km you have to change the oil (1 liter of vegetable oil). Initial plans are to produce 3,000 cars per year."
The thing is there isn't just a lot of compressed air lying around. Thanks to thermodynamics, it costs more to compress the air than what we get out of it when we uncompress it. And it's probably oil or coal burning plants that compress the air. So this isn't solving anything. The reason gasoline is so useful is that it's already been made by nature, so we can get energy out without putting very much energy in. So that only leaves compressed air as a useful energy storage device, and I have to suspect that the other alternatives (hydrogen, fuel cells, electric) do better in that department.
Would you care to show the math to back up that assertion?

I heard Ford has just developed a new shade of red paint! That's kind of like automotive innovation...
I saw this on The Science Channel and I knew instantly that I had to have one.
I'm going to put solar panels up to power the compressor.
Then I plan to drive around to all the gas stations, pull up to the pump
sit there a minute then proclaim "No, I don't think so." as I pull away with a huge shit eating grin.
FU to all the mega corporations that have made it religion to rape the little people into utter poverty.

The capitalistic douche bags that will do anything to keep a new technology (a threat to their entrenched interests) from entering the market, no matter how good it is.
If only we could find technologies like this to spend 450 billion dollars on... then again maybe your right it's a pipe dream. Let's just use the money for a war in Iraq instead.
On the other hand, if you want to joke about French cars, go ahead.
