A Cheap, Zero-Emissions Car

A Cheap, Zero-Emissions Car

If someone tried to sell you a zero-emissions car that costs around $10,000, you might think he was full of hot air. Turns out it’s the car that’s full of it: The vehicle runs on and emits nothing but air. Now, after more than 15 years of languishing in automotive obscurity, it’s heading for mass production.

The Air Car is the brainchild of Guy Negre, a French inventor and former Formula One engineer. In February, Negre’s company, Motor Development International (MDI), announced a deal to manufacture the technology with Tata Motors, India’s largest commercial automaker and a major player worldwide. “It’s an innovative technology, it’s an environment-friendly technology, and a scalable technology,” says Tata spokesperson Debasis Ray. “It can be used in cars, in commercial vehicles, and in power generation.”

Though Negre first unveiled the technology in the early 1990s, interest has only recently grown. In addition to the Tata deal, which could put thousands of the cars on the road in India by the end of the decade, Negre has signed deals to bring the design to 12 other countries, including South Africa, Israel, and Germany. But experts say the car may never make it to U.S. streets.

The Air Car works similarly to electric cars, but rather than storing electrical energy in a huge, heavy battery, the vehicle converts energy into air pressure and stores it in a tank. According to MDI’s Miguel Celades, Negre’s engine uses compressed air stored at a pressure of 300 bars to pump the pistons, providing a range of around 60 miles per tank at highway speeds. An onboard air compressor can be plugged into a regular outlet at home to recharge the tank in about four hours, or an industrial compressor capable of 3,500 psi (likes those found in scuba shops) can fill it up in a few minutes for around two dollars. Celades says optional gasoline or biofuel hybrid models will heat the pressurized air, increasing the volume available for the pistons and allowing the car to drive for nearly 500 miles between air refills and about 160 miles per gallon of fuel burned.

Early media reports speculated that Tata could have an Air Car on the market by the end of 2008, but Ray says it’s likely to be a couple of years before the technology is available. Until the Indian models hit the streets, the best way to see an Air Car in action is to cross the pond and check out Negre’s prototypes in France–a trip entrepreneur J.P. Maeder says is worthwhile. “It’s not a fantasy,” he says of the car. “It can make a real impact in how personal transportation will develop from here.”

In 2003, Maeder formed ZevCat, a Califonia company that aims to bring the Air Car to America. So far, however, he says his plans have stalled for financial reasons: Without enough money to build and crash test prototypes, he can’t demonstrate the technology for investors who might be willing to fund more prototypes.

The car might garner more attention in the United States if it makes it to market in India or elsewhere before other burgeoning technologies like plug-in hybrids or fuel-cell electric cars. If that were to happen, compressed air could become the “next big thing” for green-minded drivers, says Larry Rinek, an auto analyst with the international market-research firm Frost and Sullivan. But Rinek questions whether the car will have mass appeal. Another unknown is whether the vehicle could pass crash tests.

“This is an R and D novelty; it’s a curiosity that is nowhere near ready for primetime,” Rinek. “It’s unknown and untrusted, particularly here in North America,” where he says adoption of new technology moves “very slowly.”

How timely. Today as I spoke with Argen in India, tech support for my new wireless router by TRENDnet to be connected online, while waiting for my Vista powered laptop to catch with our actions... I asked him if he is familiar with the Nano and the compressed air vehicles from India. He stated he is and will be acquiring the Nano in the future as they become more available. I told him we need to the inexpensive vehicles available here in the US to create economical competition against our expensive Detroit attitudes.

Hang on, there's a catch. You need to use an electric or gasoline compressor to compress the air. In the USA, at least, 63% of electricity is generated using fossil fuels.

That means you're transforming fossil fuel into electricity, and then transforming electricity into compressed air. Each time, you lose a sizable percentage of the energy through heat and other conversion losses.

To make matters worse, compressed air just isn't a good way to store energy. If it was, we'd have been running trains, cars, boats and aircraft on it for years.

So, yes, it makes a great headline. It's just not practical.

Ultimately, the energy source for this technology is electricity. Therefore the "greeness" of the solution will depend on how the electricity is generated. Make it with dirty coal, and this won't be a planet-saving solution.

If you've never heard of Tata, they now own Jaguar, Daimler, Land Rover...

If we loan money to vehicle manufacturers they need to advance the possibilities of using compressed air for our transportation needs at affordable prices that anyone can own and use to save our environment. They have been ripping US off for the past 65 years. They have manufactured more expensive, more complicated, more costly products that appeal to the ego instead of eco (logical) needs of our society. No bonuses, lower salaries...trim the fat and waste of these corporations...now!

So lovely sweeties! *_*

I grew up eating it, picking it off trees in our yard, I still do, I love it .

This is fucking stupid

Now that would make a happy bather! Thanks for sharing.
