Tata Intends To Sell Air-Powered Car In India

Diggester writes "Tata Motors (an Indian car manufacturer) is changing things up with the first car to run on air, the Airpod. The Airpod's technology was originally created in France at Motor Development International but has since been bought by Tata in hopes of bringing it to the Indian consumer car market. With virtually zero emissions and at the cost of about a penny per kilometer, it is definitely one of the most environmentally and economically friendly vehicles in the world. The tank holds about 175 liters of compressed air that can be filled at special stations or by activating the on-board electric motor to suck air in from the outside. Costing about $10,000, this car could beat out most smart cars from the market." If flying cars aren't available, sucking cars seem like a nice stop-gap.

    This is not an original concept! SEE: http://www.aircaraccess.com/history.htm Brief quote: For half a century the air-powered locomotive was a serious contender for the top spot in transportation because of its obvious advantages: simplicity, safety, economy, and cleanliness. Air engines were built first during a period of experimental daily use in metropolitan street transit during the 1880s and 1890s, by companies organized by inventors and air car advocates such as General Herman Haupt. In New York City a building-sized 1500 horsepower compressing station was constructed for the use of the transit locomotives that were being tested there on daily routes. Air-powered mining locomotives were manufactured routinely by steam locomotive companies. Until the 1930s and 1940s the air mule had no serious competition from electric or internal combustion engines in mining because the heat and spark made them unsafe in closed-in and gassy places. The term "air engine" disappeared from engineering textbooks between 1931 when William Lawrence Saunders died, and the end of the second world war. Gas engines had been perfected, the power of the oil industry was established, and gas was cheap.

      Actually, the main limitations on most "automotive" style li-ions concerning charging time are not the batteries - it's predominantly how fast you can supply the power and how quickly you can cool the pack. Anyone who's seen the sort of crazy stuff cutting edge RC hobbyists are doing with rapid charging/discharging li-ion packs knows that these things can take some serious abuse!

      Can't do that with "laptop" style li-ions, though.

      Cooling the pack and cabling well, I don't think anyone seriously considers that a major long-term roadblock. Just basic engineering. Supplying the power that fast can be done (the cabling doesn't even need to be too fat to be unweildy, due to cable cooling), but to do it direct from the grid requires a crazy big feed and all the start-and-stop makes the power company unhappy with you ;) More practical approaches will involve a secondary battery buffer at the charging station, trickle-charging from the grid (or on-site generation if so desired). Ironically, one of the best buffers could be used EV battery packs, bought on the cheap because of their reduced capacity, and strung together.

      The possibility leads to options that gasoline vehicles can't match. For example, in theory with today's tech (aka, if anyone built such vehicles and systems), you could drive up a li-ion EV to a solar-powered charging station plunked down in the middle of a barren wasteland, hundreds or thousands of kilometers from civilization - and in 5-10 minutes have a full or nearly full charge and drive off. Technically it's *possible* to make fuel deliveries out to really remote locations - but between the cost to install the tanks and such for a gas station in the first place and the cost of deliveries, it wouldn't begin to compare.

      Interesting.
      Assumptions:
      EV battery, new 53kwh (Using the Roadster as a model): Cost isn't good at $36k, but I've said 'there's nothing wrong with EVs that a battery that lasts twice as long for half the price wouldn't fix'. So let's say that 'futuretech' and economy of scale has reduced the price to $9k.
      Recycle value: 50%; Most car batteries are retired at 80% capacity(42 kwh).
      Power: 'Demand' is 20c/kwh. 'time of use' is 40c/kwh peak, 10c for lowest demand load balancing.
      Statistics: Average power usage per household is ~1k kwh/month. Average car miles 12k. Average of .25 kwh per mile for an EV. 2 cars per household(2.28, I'll round down).
      Charge efficiency: 90%

      At 20 cents a kwh(expensive, but green!) you're looking at $1333/year(it'd be $1200, but charging isn't 100% efficient) for your fuel bill(2 vehicles, 12k miles each). Compare this to an estimated $3,200/year for 30 mpg gasoline vehicles @$4/gallon. Savings: $1.9k/year. Not bad. If my thus far theoretical $9k battery lasts 5 years, its' worth it. Minus the battery, electric cars are as cheap/cheaper than an equivalent gasoline burner, and will probably last longer.

      If you're charging overnight, every night, on average you'll need to transfer 18 kwh to recharge from the average 66 miles driven that day(actual results WILL vary, these are household averages!). At 240V, that's 75 Amp-Hours needed. If we figure you need to do that in 5 hours(remember load balancing), that's 15A.

      On to the battery at home:
      Let's say that you drive DOUBLE the average(IE it's a good case). You'd need 30A for 5 hours to, or 15 for 10, and the power company isn't happy about it. You'd like to save more money as well. You use an average of 36kwh a night charging your cars.

      You buy a used 42kwh 80% battery for $7.2k and install it. Let's say the fancier system raises the total cost to $10k*. However, you sign up for the time of use charge system and thus, if you can shape your electricity use well enough they only charge you 10c/kwh. If all electricity for charging the car goes through it, it should drop your bill from $2666 to $1480($1333*2/(2*.9)). Remember the extra efficiency loss! Save $1.2k/year. Little over a 10 year payoff. At this point, not worth it.

      However, odds are that not ALL of the charge for your cars will come from the battery(saving some of that .9), and you bought the 'extra fancy' system. It also provides load balancing* and UPS protection for the house. Most HOMES only use 33kwh/day, so if you're not driving you can enjoy a full day with power even if the grid is down. That alone can cost $10k to get a generator, so it would make a huge difference.

      Conclusion: If we can get the batteries and other components cheap enough, it's certainly an interesting option.

      *IE it switches to battery when the power company sends the 'time of use' cost of electricity above 20c/kwh.

    It's an interesting idea, but they don't say anything about what that 175 liters gets you in terms of distance or power. The onboard pump is interesting (and necessary IMHO) but India's power infrastructure may not be up for the task of hundreds of thousands of cars all pumping away... if they're targeting cities, or they can get these filling stations everywhere, it might be alright.

    The real problem with all these compressed air vehicles is the diabatic nature of compressing air. When you compress it, you generate a huge amount of heat that's hard to use and slows down the filling process (since the pressures are higher than normal, which will be problematic for the service station idea), but when you expand it (for power) you need to re-heat the air or else your efficiency goes way down since super-cold air doesn't have much volume. That's why they immerse SCUBA tanks in water while filling. If they figured out how to minimize that problem (maybe they use it slowly enough that it's not an issue?), they should sell a lot of them. TFA doesn't have anything suggesting that they have, though... so I'm skeptical.

The wiki article on compressed air cars has a comprehensive list of their rather substantial disadvantages. Really the only situations where air cars are even considered are those where sparks or burning of fuels make both internal combustion and electric too dangerous and where their limited range and power are not substantial disadvantages. As one might imagine, these circumstances occur rarely and only in specialized situations (most notably in underground coal mines). Bottom line: air cars are simply not competitive as general purpose vehicles and basically never will be due to the laws of thermodynamics and ideal gas among others. Those who buy an air car without understanding these things are likely to be very disappointed with their vehicle's performance.

      Low energy storage is real, and a real drawback. It's shared with EVs, though, which have long storage times. Air cars do not have a long storage time, the appeal of the tech as opposed to EVs is that they recharge very quickly. You have a tank at home and it fills up when you're not looking (whenever energy is available/cheap.) Windmill-based storage stations out and about can fill themselves (with a tank in their center) when the wind blows and provide rapid refills. MDI even proposed using the technology on barges which could be stationed in a current.

      Does need heat to expand air, but the air is at very high pressure. Most people live where it will work, though.
