Air-Powered Hybrid Cars?


More than ten years ago, a French Formula One expert had an idea. Instead of running cars on the chemical energy of gasoline...why not run them on the physical energy of compressed air? Now that vision is extremely close to reality. Already, prototypes of "The Air Car" are on the road (see videos after the jump) and several companies have licensed the technology.

The idea is that regular old air is compressed in ultra-strong tanks in the car. Then, that air is released through a couple of pistons in the engine, which drives the wheels. Current prototypes get a bit more than one horsepower and levitra online can push the canadian pharmacy levitra cars up to 70 mph for about 120 miles. It's not in any way comparable to something you might go and buy on a dealer lot today. But there are some significant advantages.

For one thing, it only costs about three dollars to fill up the tank. For another, the car has no emissions. In fact, the air coming out is significantly cleaner than the air in most cities. Of course, it will take some electricity (from coal power plants, yes) to compress the air, but the carbon savings are still very significant.

The re-filling process is simple and quick (if your gas station has been retrofitted with ultra-high-pressure air compressors). Several companies, most of them fairly small, have licensed the technology to produce the vehicles. However, one very large company, Tata motors, India's largest car maker, has plans to produce air cars and has released several designs for what they're going to be producing.

Tata is planning on creating a hybrid version that uses compressed air at low speeds, and then switches over to gasoline if the driver needs a speed (or range) boost.

As for a U.S. release, we're going to have to wait a little longer. Though the cialis generic cheapest technology has been licensed here, it might be a while before the cars can match up to the safety regulations of the United States...or the voluminous desires of American consumers.

But for the rest of the world, the emerging markets that need cheap transportation...this could be a fantastic alternative that truly makes the world a much cleaner place than it would otherwise be.

Check out a slew of videos after the jump.

I imagine it would take a tremendous amount of power to compress air to such high density. If it doesn't, wouldn't it be nice to have your solar panels on the roof of your garage busy running a compressor during the say so when you get home at night, you can fill up your car.

Not that much power
written by Daniel, January 04, 2008
From what I can gather, the air is pressurized to about 4500 psi. While you'll need a high pressure compressor to compress it, it may not need to be a big compressor. If service stations (and owners at home) had a smallish, high pressure compressor that ran throughout the day, they could store the air and would fill the car off that. You could fill the car directly off the compressor too, but that'd take much longer without it moving a really high volume.

Carbon Savings??
written by RhapsodyInGlue, January 05, 2008
Hank, I would challenge you to back up the assertion that an air car fueled by a compressor driven by coal plant electricity would be any savings in CO2 much less very significant.

Keep in mind that much efficiency is gained by virtue of the fact that this is a very small, light car. If the same shell were fitted with a small, light gas engine it probably would do as well if not better in CO2 terms.

difficult to believe
written by Airmon, January 05, 2008
This concept has been around for decades, but has yet to be practically used. Looking at how this works, I think I see the problem.

The energy is stored by compressing the air. The energy is returned by using the expansion of the air to drive a piston.

The tank has air at 4500 PSI at the start, but the engine uses air at 450 PSI ( 30 bar - according to the video ). To regulate the air down to this level, you're going waste most of the energy of the air.

That can't be efficient.

I'm a bit curious about the safety issues involved with having a tank in the back of your car at 4500 psi. If that tank ruptures in a collision, it's not staying in the car.

One major inefficiency
written by Adiabatic, January 05, 2008
One penalty to using compressed air is that compressing the air causes it to heat up. If your tank could stand the heat and usefull link what is the cost of cialis you used the air immediately, you'd minimize the loss. In real life, the tank would have to be cooled during filling (like a scuba tank is.) That's energy that you paid for, but won't have available to drive the engine.

The overall efficiency is what matters in the end, though. It would be interesting to compare how far an EV and one of these both go per KWH in.

On the other hand, while batteries may be more efficient, these may be less expensive. Less expensive means more in use. A lot of good may have more benefit than a little of the best.

There is not a significant amount of energy lost regulating down from 4500psi to 450psi. The more significant problems with this are related to safety (who wants to be the passenger who sits on top of the ultra high pressure tank? Oooh, me me).

And as for the idea of a solar panel powering something that can pressurize the very good site viagra gel tank. Oh ho ho.. Oh. my.

Not unsafe
written by AperatureScience, January 07, 2008
They use carbon fiber composites for the tanks, which split rather than explode. It's the only material that's light/strong enough anyways.

Compressed air vehicles are a fascinating technology to me, but the heat problem brought up by 'adiabatic' is troubling. Attaching a heat pump to the output and powering it with batteries would make an Air-electric hybrid with potentially higher efficiency.

It's a proven technology with some advantages over even BEVs, such as simpler (pure mechanical) drivetrains, and lighter motors. Like BEVs, they have high efficiency and you can charge them at home. Tanks aren't hazardous either, unlike some battery chemistries. It's a technology to keep your eye on, at least.

Potential
written by NatureGeek, January 08, 2008
Interesting... regardless of whether it would use less energy/leave a smaller carbon footprint to power the compressor vs. a small light gas car or not, it does centralize the potential source of pollution/carbon. This could be good because as we move away from polluting sources of energy to greener ones, that power would get greener, where the gas car is still a gas car. So this little puppy, if it in fact comes to fruition and proves viable, has the potential of lowering its emissions over its lifespan, if we can lower the emissions of the source of energy for the compressor.

I agree it sounds a little scary, but then again, we ride around with highly explosive gas tanks under us all the time now, so, it may be able to be made safe. I'm not saying it is now, or isn't, just that I see potential here.

As one person pointed out, compressing a tank full of air to 4500psi would generate a lot of heat. If done directly to the cars tank it would probably need to be done over a fairly long period of time to allow safe dissipation, such as overnight. Or, a central filling station could compress air, cool with a heat exchanger and it's great! cialis in spain store in a stationary tank, possibly at even higher pressure. If one were clever, they might even have the filling station somewhere that the generic levitra without prescription heat exchanger could provide a useful service such as heating water. That would certainly improve the energy balance for this technology.

Big drawback, however, is that the energy and power output goes down in winter and colder climates. Plus, heating the interior would require stealing useful mechanical power. Therefore, this looks much more attractive for tropical climates.

Talk about efficiency
written by Gus Ano, May 03, 2008
Most governments will not be able to forbidden the use of air powered vehicles, since they are not burning anything, therefore there is no internal combustion engine.

Furthermore, our internal combustion engines that we use in our cars now are teeribly ineficient since they burn the fuel and therefore they produce innecessary heat that can melt the very same engine, therefore we have to power a very powerful cooling system in order to maintain the engine heat at reasonable levels, which means taking the just try! levitra canadian heat into the air.

That's higly inneficient but we are used to it because oil was so inepexsive. Expanding air can be used in machines as shown above, but also it could be used in turbines, which are a lot more efficient than this engine.

Also no heat is produced whatsoever in the process.

If the air is compressed enough, it could be liquified, meaning you could go for 800 miles in one tank, for about $3.

Talk about efficiency.

Also if we use the breaks to power an small compressor, we could save a lot of energy, in the same way that hybrids use the breaks to restore power in the batteries.

This is a completely small picture discu
written by Chris, May 13, 2008
Excuse me, but I have 3 kids and a life which actually takes me beyond a city loft apartment and organic, free range coffee house. If I want to take the lads to a ballgame in my 1200lb air car, it sure as hell is going to take a looooong time to get there because of the weight. And in the process, I will use lots more air than a single driver. As well, I can expect to stash one of my kids on the roof, as there'll be no room under it.

Get real. For an urban use vehicle, this rocks. But already we could be driving (as Europeans and www.celebratinglife.org Japanese already do) micro cars with 1 liter gas motors which are more efficent in terms of power production and conversion than this method.

Weight = the enemy. If you want a safe car, that requires weight. If you want a larger cabin to support more bodies, that requires weight. The petrol combustion engine is no more evil than any other power source which utilizes heat for catalyzation. With appropriate gearing, weight minimalization and low coefficient of drag, we could dramatically reduce our use of fossil fuels.

And I'm not a dupe or shill, just somebody who wants to take a measured approach to change. Invariably, down the road, movements be they religious or social have a way of propagandizing away some merit. If someone can simply do an honest comparison of the possible locomotives and their actual power/pollution unit, I'll be happy. And yes, I know coal and gas each have their own pollution matrix.

thanks.

This car is a real threat to the oil/gas/coal companies because of the fact you could fuel this car at home with a combination of your own wind mills and solar panels. I watched another video which showed with the combination of gas and compressed air, you could get from san francisco to new york on one tank alone! http://www.youtube.com/watch?v=QmqpGZv0YT4

Guys, we need to quickly reduce our dependence on oil, for security, environmental and financial reasons. Don't listen to all the hype about drilling in ANWR and the gulf coast. Continuing our addiction to oil in the long term is not the answer. We need to drastically reduce our consumption of oil right now and this will in effect lower the prices at the pump because it's supply and demand folks! Once demand goes down, prices go down. Of course, the oil companies don't want that to happen, so thats why Fox "News" and all those right-wing talk show idiots won't push for wind power, solar panels, compressed air cars or electric cars as a large solution to our problem. Their solution if continuing our dependence on fossil fuel for the benefit of the oil companies.

Individual energy independence is a HUGE threat to their bottom line and are spending millions of dollars to confuse the viagra, candadian drugs public and how to get cialis no prescription all of us have been victims of their propaganda at one time or another.

Air beats batteries
written by Pilgrim, September 08, 2008
The carbon-fiber compressor tank has a more favorable power to weight ratio than batteries. To store a comparable amount of energy a compressor tank beats the weight of batteries hands down.

As numerous comments have already observed, there is a net loss recovering mechanical energy converted into compressed air. Few mention that there is also a net loss recovering mechanical energy converted into electricity stored in batteries. I would venture a guess that energy stored as compressed air would actually fare better than batteries for efficiency of recovery.

The size of a compressor tank can be easily accomodated in a vehicle design because it is lightweight and doesn't require heavy structures to support. Conversely, batteries require heavy additional structural support plus expensive corrosion resistant materials adds to production costs.

Once air hybrids hit the streets, 2nd and 3rd generation improvements will further refine the breed. Electric hybrids will then be destined to dinosaur status.

written by avagadro, February 19, 2009
It is a shame that so many of the people who love the air car have no education in science. If they did have knowledge of the science involved they would readily see that the air car promises what they can not deliver.
If you understood the processes involved and followed the energy through the system, you would realize that air is a very poor energy storage medium. The amount of air in the atnk at 4500 psi can not move a vehicle more than a few miles.
All of the info you need to evaluate the concept is readily available on the internet.
The air car company understands that people like to believe in ideas that will benefit them, if people were objective they would take the time to understand what was being discussed instead of blindly believing what a promoter claims. All we have from the air car company is claims, no proof whatsoever, isn't that odd? Just what are words worth? To me they mean nothing without proof.
10 years of promises that have never materialized tells you something.

If you believe the claims that have never been proven, you do yourself a disservice. The claims made by MDI have never been independently verified and levitra 20 mg are in violation of the laws of thermodynamics.

What about a car that uses an electric engine to start the car, then powers the air motor to compress air and also start the Air engine when the compressed air is at its maximum which then switches off the electic engine and also charges the battery, when the battery is full starts the electric engine and so on. To start this process you can either put in compressed air or even charge the car through the mains or even both.
