What a nonsense. Following that logic my diesel car has unlimmitted mileage because it doesn't use any gas at all. Electricity is energy too.

I am waiting for a air powered truck to hit the market, I think air powered is one of the best ways to go, no batteries, less weight and less maintenance and should cost less.

I hope you just made a new technological breakthrough because the air powered technology I know of isn't very usefull in cars.

The air powered auto's are coming up in better technology, mostly in the past 2-3 years, in France they use air powered buses around some cities and they are doing quite well, yes they have a ways to go and so does electric auto's as well, but soon it will be mainstream and just maybe go about 200-300 miles before filling air tanks.

Interesting, haven't heared of that before. Do you have any links?

Also just type in air powered cars in your google search and go thru all the listings, the latest one says it can go a 1000 miles.

But you have to admit that the air powered auto's are a neat idea, I think they are the real future of auto transportation, no batteries to replace for thousands of $$ after they wear out, less weight and less cost.

Mexico City, one of the most polluted cities in the world, could see air-powered taxis on its streets by 2002.

Factories producing a car billed as non-polluting are due to open in Mexico next June, and the first taxis are expected to roll off the production line eight months later.

The vehicle - which is said to run on compressed air - is currently being produced in France, where the first factories have already been installed.

The car's creator, French engineer Guy Negre, says it is the first viable alternative to vehicles that run on conventional fuel.

But some people argue that new car will not reduce pollution because electricity is needed to compress the air.

They say that the extra electricity is likely to come from fossil fuels, creating an added source of pollution.

The compressed air on which the car runs is stored in tanks, similar to scuba-diving tanks, attached to the underside of the car.

The release of air acts as fuel and activates the piston engine.

Mr Negre says a tank-full of air - on which a car can travel up to 200km (120 miles) at a speed of about 90km/h - is equivalent to two litres of petrol.

If fleet owners install their own air stations, filling a car with 300 litres of compressed air could take three minutes.

Alternatively, the designers say the car could be plugged into any electrical power source to fill it up. That could take up to four hours.

The first models of air-powered vehicles - taxis, small pick-ups and delivery vans - are expected to be on the market later this year.

Motor Development International, the company which owns the patent, says that rather than mass-produce the car, it will sell franchises to local manufacturers.

Each factory will have the capacity to produce around 2,000 vehicles a year.

There are already plans for five production units in Mexico, as well as others in South Africa, Australia, the United States, Spain and Switzerland.

The Mexican taxis have been especially designed for the capital city.

Some hope that the new air-powered cars will eventually replace the city's petrol and diesel taxis, nearly 90,000 in total.

Motor Development International says that the Mexican authorities have shown interest in their cars as a way of fighting the city's pollution.

But you have to admit that the air powered auto's are a neat idea,

It sounds even better than water powered cars. The problem is energy density. If I fill a 100 liter bottle with air upto 3,000 psi, it'll cost me about 10 kWh. That's about 0.3 GGE. I cannot get out more than I put in. I won't get very far on 0.3 GGE.

You need to look at the whole picture here, ...to large storage tanks than reloaded again into another truck to be deleverd to your corner gas station that uses electricity to pump it in your 15 gal tank.

I would say for the little electric that is used to fill the high pressure air tanks with free abundance air is a whole lot less of a energy waste than a gal of gas any day of the year...

Oh Yea and we don't need to spend trillions of dollars in are military to keep that air flowing like we have to do with oil...

Ok so speaking of electric cars- it seems like every car company is talking about making one... the Nissan LEAF, BMW, Chevy Volt, Honda, etc. My question is why aren't any of these companies talking about NiMH batteries (with the exception of Toyota). NiMH batteries are inexpensive, durable, and proven to work... They've been running electric cars on the road for decades. They are a little heavier but so what? I just finished reading a book, Two Cents Per Mile by Nevres Cefo, which is an insightful book about electric vehicles which in parts argues for NiMH batteries, and I was wondering what you all thought about them.
