[biofuel] Air-car doesn't work
It's been discussed here a few times before, I beleve we were sceptical, mostly. But he nonetheless gets $13 million in investment for something that doesn't work. Well, at least he admits it, sort of. Other people with things that do work get nothing. - K --- Detroit Free Press http://www.freep.com/money/autonews/aircar18_20040318.htm Experimental car is powered by air Experimental car is powered by air French developer works on making it practical for real-world driving March 18, 2004 BY WILLIAM DIEM FREE PRESS SPECIAL WRITER CARROS, France -- In an industrial park a few miles from Nice on the French Riviera, Guy Negre has developed an environmentalist's dream car. Compressed air is the fuel, cold air is the only exhaust. A prototype van called CityCAT -- the sixth made by his company, Motor Developpement International s.a. -- tools around the parked cars of his staff of about 30 just as any small van might, except that the power is coming from three long black tanks in the back, full of air compressed to 5,000 pounds per square inch. No powertrain could be more environmentally attractive. It requires some up-front electric energy to compress the air, and that's all. Like an electric car recharging its batteries, you could plug it somewhere when the air pressure has fallen too low and have the on-board compressor refill the tanks. The car and Negre's invention have been on television on every continent. More than a dozen investors from Mexico, France and elsewhere have invested $13 million for 35 franchises on a future mini-factory and sales territory. The only problem is, it won't work in real life. The clean engine is insufficient to be sold, he says, after seven years of development. The air-powered car has too little power and too little range. Negre's son Cyril, an engineer at MDI, said that the CityCAT prototype goes about 37 miles on the test track before it runs out of air. However, Negre is not waving a white flag. He is simply returning to an engine he started designing in 1992 after a career designing Formula 1 engines. The air car engine, he said, will now get a clean-burning external combustion chamber so that the CityCAT can operate as a hybrid with two energy sources: running on compressed air from the tanks or burning fuel to expand ambient air, which powers the pistons. All motors are essentially compressed air motors, he said in an interview at his company headquarters. Internal combustion in a standard diesel or gasoline engine simply heats and expands air. He would not describe in detail the changes he expects to make for his new engine, except to say that the external combustion would produce tiny amounts of exhaust pollution. As for fuel economy, he said, On an early engine, we achieved 2.5l/100km (94 m.p.g.), and this one will do better than that. Negre doesn't dream small. Starting with his compressed air engine in 1997, he developed the idea of a Green Taxi for city centers. That has evolved into two cars, the three-seat MiniCAT and a five-seat CityCAT. He has an idea for a compressed air bus. To build the MiniCAT and the CityCAT, he has designed a small factory with a capacity of two cars an hour -- about 7,000 cars a year -- where workers would manufacture engines and body panels and assemble the finished product. In six to 10 years he hopes to have 400 factories around the world, 20 of them in France. In the concept, MDI will deliver the raw materials to the factories, to assure the same quality everywhere, said Negre. His dream doesn't really match the reality of industrialization, validation and government approvals. Negre's new engine with the external combustion chamber is still in the design stage. It isn't expected to reach the prototype stage until the end of this month, yet Negre is confident he can validate it and sell his first MiniCATs by the end of the year. That is unlikely. Automakers with huge resources take years to validate an engine and test its durability. Negre has a small staff and is operating on a shoestring, without enough money to return to the Paris auto show this fall. His dream has some credibility, because his air car works. Compressed air gives an adequate performance in city driving for a limited time. But MDI is a long way from taking on the big automakers. March 18, 2004 Yahoo!

RE: [biofuel] air car
Sorry about that.. i guess it is the medium. I misinterpreted what you were saying. Of course.. this Is kind of silly since the 'car doesnt exist' ha. but if you can just compress the ambient air.. there certainly could be benefits such as not having to deal with pure hydrogen and oxygen. a benefit if you could do it with solar..wind..etc would be that you could do it off the grid. Wind kind of leaves those in the city out, though.. not much free space. Those that do have free space, may not be within range of work.. I think that cities are naturally good at channeling winds.. i wonder why certain places can not use wind. and I havent seen any on buildings.. as to your 'South California Edison', I am pretty happy with my power company.. I think a more local level power can be ok.. but too local that there arent adequate safety measures.. etc. the guys pulling off cat converter equipment to 'save a buck or two' Have a good day. :) Message: 8 Date: Fri, 31 Jan 2003 12:20:18 -0800 From: Tricia Liu [EMAIL PROTECTED] Subject: Re: air car It's a follow up on your topic on energy storage.

Re: [biofuel] Air car.
Consider for a moment the possibility of a conventional IC engine powered vehicle that could convert much of the energy wasted in braking (engine and conventional brakes) into compressed air storage that would be in turn used to supercharge the IC engine when again under load thereby increasing cycle efficiency. Small storage requirements -- low cost energy recovery/conversion apparatus. Another form of a hybrid vehicle. [Non-text portions of this message have been removed] Yahoo!

Re: [biofuel] Air car.
Hello all participants of air car debate, I think that the technique opens up a range of interesting solutions and will try to mention a few, 1. The major value is not as an energy efficient way of running a car. As such, I agree with several of you, that pointed out its lack of conversion efficiency. 2. Several times on this list, people have pointed out the flaws in looking at single stage or a few stages efficiency. Only a few weeks ago, Keith wrote in an elegant way about this. 3. The value of the process is very large, if you look at is as a combination of conversion and storage technique. Using air and air pressure, seems to be a technique that solves a lot of space and weight issues. The limitation in the conversion back to other forms of usage, have probably taken a large step with development of this engine. 4. Most of renewable sources, like Sun, Wind, Hydro etc. need large storages, to be viable alternatives on their own. Hydrogen that at best have 1-2% efficiency from production to use and in most cases have a negative efficiency, have been argued more on its storage and conversion properties. But if you look at the distribution facilitation, it is both costly and time consuming. Compressed air is easier, less costly, safer and cleaner. 5. Contrary to what somebody said, we have a very large element of electricity production with basically diesel fuel. The reason is the ignorant engineering in the building industry, that generates huge peak demands. Those peak demands are covered by small power plants, driven by oil products. The reason is the short start/stop times that are needed for the generation. A lot of losses are taken on off peak times, because of that the major power plants are idle. The storage technique could have a major place in this equation. Especially on the air conditioning side. 6. One of the arguments for its use in the automotive sector, is the health problems in our cities. It is a compelling argument and I can not find anything wrong in it. Maybe we have negative gains in over all pollution, but the power sources are not located inside the cities and by the dispersion of the pollution, we will have a positive effect on the health. The pollution problem is also easier to improve in a few power plant, than in millions of cars. 7. An often used technique in hydro electric dams, is the pumping back of water to storage dams. This can not be claimed as energy efficient as a process, but is for sure efficient as a whole. The compressed air technique will have similar benefits. As I go on writing this, the ideas of applications flows faster than I can write. It is better to draw a line here, because I think that the case is clear. The value is the compressed air as storage of energy and the engine is a missing link in the conversion chain to use of the compressed air. Hakan wrong in this. Yahoo!

Thanks for some interesting ideas. I have been debating with someone in the global energy options about vehicles powered by Liquid Nitrogen and it has also raised some of these issues. While that type of power concept does not appear to be nearly as well-developed, I think that it could be included as being of somewhat similar value, particularly since there is a chance that it could store even more energy than compressed air, per unit volume or weight or mass. I agree with some of the things you point out, including that we needn't necessariliy confine our considerations to vehicles. Even if compressed air vehicles have problematic range, the more-basic consideration is: is it a viable and useful way to store energy or not? MM Yahoo!

RE: [biofuel] Air car.
I think the process pencils better if you liquify the nitrogen rather than compress it. This is even more so for refrigerated transport where the refrigerator is useful load. In the Southwest even air conditioning is a large load. Kirk -Original Message- From: Hakan Falk [mailto:[EMAIL PROTECTED] Sent: Saturday, September 14, 2002 4:38 AM To: biofuel@yahoogroups.com Subject: Re: [biofuel] Air car. Hello all participants of air car debate, I think that the technique opens up a range of interesting solutions and will try to mention a few, 1. The major value is not as an energy efficient way of running a car. As such, I agree with several of you, that pointed out its lack of conversion efficiency. 2. Several times on this list, people have pointed out the flaws in looking at single stage or a few stages efficiency. Only a few weeks ago, Keith wrote in an elegant way about this. 3. The value of the process is very large, if you look at is as a combination of conversion and storage technique. Using air and air pressure, seems to be a technique that solves a lot of space and weight issues. The limitation in the conversion back to other forms of usage, have probably taken a large step with development of this engine. 4. Most of renewable sources, like Sun, Wind, Hydro etc. need large storages, to be viable alternatives on their own. Hydrogen that at best have 1-2% efficiency from production to use and in most cases have a negative efficiency, have been argued more on its storage and conversion properties. But if you look at the distribution facilitation, it is both costly and time consuming. Compressed air is easier, less costly, safer and cleaner. 5. Contrary to what somebody said, we have a very large element of electricity production with basically diesel fuel. The reason is the ignorant engineering in the building industry, that generates huge peak demands. Those peak demands are covered by small power plants, driven by oil products. The reason is the short start/stop times that are needed for the generation. A lot of losses are taken on off peak times, because of that the major power plants are idle. The storage technique could have a major place in this equation. Especially on the air conditioning side. 6. One of the arguments for its use in the automotive sector, is the health problems in our cities. It is a compelling argument and I can not find anything wrong in it. Maybe we have negative gains in over all pollution, but the power sources are not located inside the cities and by the dispersion of the pollution, we will have a positive effect on the health. The pollution problem is also easier to improve in a few power plant, than in millions of cars. 7. An often used technique in hydro electric dams, is the pumping back of water to storage dams. This can not be claimed as energy efficient as a process, but is for sure efficient as a whole. The compressed air technique will have similar benefits. As I go on writing this, the ideas of applications flows faster than I can write. It is better to draw a line here, because I think that the case is clear. The value is the compressed air as storage of energy and the engine is a missing link in the conversion chain to use of the compressed air. Hakan wrong in this.

Re: [biofuel] Air car.
I am going to continue to watch their efforts with an open mind. I am interested to find out what energy efficiency they are able to realize in converting the air into motion. I am also interested to learn the energy efficiency of compression. From their web page it would appear that there is more than one compression scheme (one for home, one for on the road, though I'm not quite sure what this means). There is usually one or more pretty severe drawback to each proposed competitor for the IC engine, and I am aware that range is a drawback of this proposed car (as it is for batteries). But I want to see what they have to say. The extremist environmentalist case, such as where air really is virtually unbreathable in certain cities, is one that can be made in some cities. From what I understand, for example, Mexico City really does get very bad when it comes to air pollution, to the point where some vehicles can only be legally operated on alternate days, and in the face of such a problem it is perhaps not inappropriate to consider such engineering compromises as air cars. Maybe that law is no longer in place? This is not to say (of course) that other compromise sollutions, such as battery-powered vehicles, increased electric-train use, etc. etc. are not also worth considering. they don't :-) technically, a compressed tank of air runs a air motor (steam engine) connected to the wheels. unfortunately, you can't carry enough air for a reasonable range, and you waste much more energy compressing the air, than you get back from it. for further info, see http://www.howstuffworks.com/question133.htm Yahoo!

Re: [biofuel] air car primer
Hi Dick, Pedro and All, Pedro, thanks for the URL. The tanks are huge and wouldn't be practical to change though with a cooling system, more weight, they could be filled fairly fast, 10 minutes from very large storage tanks at even higher pressures. To quote their figures it takes 3.5 hours at 5kw to recharge them from their compressor. This is 17.5 Kw. How much does your electricity cost? Here it's about $.10 a Kwhr. Also in the last 1/3 of the tank power will go way down to nothing at 1/8 tank pressure, under 400 lbs, because of the way the strange motor works. At 50 mph or stop and go, hills at 35 mph, range would be about 20 miles. So that's $1.75 for 20 miles realilisticly is $.0875 a mile for fuel. Quite high vs $.01 to .02 for EV's. That's assuming he didn't use selective, unlikely satistics like in the other stats he uses in other places. For instance he does max range at 20 km/hr. Not very practical. I can build an EV to beat these easily, cheaply. In the same car using EV tech would weigh the same or less. To claim 300km at 20 kmhr to prove it will run for 10 hours says it all. --- Dick Carlstein [EMAIL PROTECTED] wrote: negre's aircar is an urban, repeat, urban vehicle. it is not designed or meant to travel on i-95 from boston to ny. it is meant to travel within an urban environment, moving driver plus four passengers. it uses 70 % of the road space, and costs 25 % of what the selectra costs. it weighs 700 + pounds less than the selectra. While this is true the Selectra will go 400 plus miles at these speeds, 35 mph. I would not want to be in any kind of crash in the air car because you will be history from it's bad space design. That doesn't include the problems of the dangers of the huge tanks that have NO crash, crush space. Even crashing into a small, 2000 lb steel car at 25 mph would be disasterous. The composite EV I'm building will be 10 times as safe at 300 lbs less including batts. Of course it's only 2+2 but still. Another problem is stabilty if you put more than the driver and even with just the driver it will roll faster than a Ford Explorer. Loaded to what the designer says it will carry it will be dangerous. It's called Center of Gravity. Another thing is the exhauts is - 30C. That's a hell of a lot of heat lost which cost money, eff. with a full charge of air the range varies between 62 and 186 miles, depending on how fast, or uphill, or heavy, you travel. At 20 kmhr , 15 mph that range is a joke. Expolating it the 62 mile range would be at 35 mph on flat with steady speed, again a joke. A good EV will beat the crap out of that. My EV can get 250 miles+ with golf cart batteries at 35 mph. it can re-charge to 100 % in less than three minutes, which neither the solectra, or any other electric car for that matter, can do. (100 %, not 80 %) True but for less cost and weight than the onboard compressor you could have an APU to charge while you drive at 1/3 the energy cost of the air car. 80% charge in 15 minutes is good enough for me. Ni-cads can go 100% in 20 minutes now. it is an alternative, not a magic bullet. just as the selectra, or the think, are alternatives. But comparitively not a not very good one. A 1909 Baker Electric will beat the pants off the aircar in range at the same speeds. The car companies seem to want EV's to fail and are making it happen. Here in the US there are thousands of people converting gas cars to electric that are very sucessful, why can't the car companies? the aircar is 100 % privately funded, and has no direct or indirect connection to any car manufacturer. And I think now that I've seen the website I know why, it's I believe a scam. Why else would they use such unrealistic satistics. If the truth came out no investors would bite. and the more the market knows about alternatives, the wiser the choice it can make. But unless you are technical you wouldn't know how bad the air car is. As a car designer it's easy for me. berating somebody's effort, or ideas, just because they don't coincide with yours, is not my idea of progress. and using information out of context -- as when comparing apples and pears -- is like cheating at solitaire. imho. It was the closest thing I could find. Other than being 25% heavier but proporionate it is a good comparision even with lead batteries it beats the pants off the air car. Cost in production wouldn't be that different considering the greatly higher performance. It also has the benifit of being independently tested, something I didn't see on the website of the air car. . I would love to see it succeed but I don't see it happening. You can't change phyics. jerry dycus '...or close up the wall with our english dead...' (again, ws) ? cheers, dick.
[biofuel] air car missconceptions
how these threads take off !!! anyhow, here's a few items of info that seem to have been overlooked: high pressure (over 3000 psi) tanks are installed in all sort of passenger carrying vehicles, such as aeroplanes, cars, and buses. all big birds have high pressure hydraulic reservoirs, usually made from epoxy/kevlar windings, besides high pressure oxy/air bottles (that feed all of those drop down masks). little birds, and war birds have hp oxy/air bottles for pilot reliability. and then there are millions of cars and buses being run world wide on compressed natural gas. these are usually aluminium bottles, and seem to be holding their own pretty well. the same service stations that today fuel compressed natural gas vehicles can service compressed air vehicles. it takes 1.5 to 3 minutes to fuel a compressed natural gas vehicle, with enough 'fuel' to run a mid size car up to 200 km. or so. filling a compressed air vehicle will not take longer. the air tanks in the air car we are discussing are fibre wound, and are designed to split along a failure seam, downwards, rather than through catastrophic focused failure. the aircar's tanks are long and narrow, being nested next to the chassis longerons. in/out is through lateral openings. the air car is presently manufactured in france. it is a thoroughly road tested vehicle. there is one us franchise already, so local non-believers will soon be able to stand corrected. it is an urban car. lightweight, agile, easy to fix/repair, crashworthy tested. an entry level urban car, low priced, and versatile (there are delivery van/pick-up/taxi/passenger car versions). and it is not the 'ultimate' solution. no vehicle is. mtbf, service requirements, topography, user profile, mission profile, opportunity cost, operating cost, are just a few of the variables that should be taken into account when comparing vehicles. as to the ev/air car non-controversy, i go back to my initial statement: we should compare energy densities, and more precisely weight/energy densities. someone posted that rolling resistance was only influential to 25 mph. i would hazard that most urban situations will be well within that envelope. once more onto the breach, my dear friends, once more.(ws) cheers, dick 'what have they that i don't ? well, for one, they snipthis is a public service message.

Re: [biofuel] air car missconceptions, you got that right:
Hi Dick and All, --- Dick Carlstein [EMAIL PROTECTED] wrote: the air car is presently manufactured in france. it is a thoroughly road tested vehicle. there is one us franchise already, so local non-believers will soon be able to stand corrected. Do you have an URL for it? How many have been built? it is an urban car. lightweight, agile, easy to fix/repair, crashworthy tested. an entry level urban car, low priced, and versatile (there are delivery van/pick-up/taxi/passenger car versions). What is it's range? Who is using it besides the factory? Who verified the performance? and it is not the 'ultimate' solution. no vehicle is. mtbf, service requirements, topography, user profile, mission profile, opportunity cost, operating cost, are just a few of the variables that should be taken into account when comparing vehicles. as to the ev/air car non-controversy, i go back to my initial statement: we should compare energy densities, and more precisely weight/energy densities. someone posted that rolling resistance was only influential to 25 mph. i would hazard that most urban situations will be well within that envelope. EV's can get over 230 plus mile range verified in an EV traveling on I-95 at 75 mph between Boston and NY. This EV only weighs 2300 lbs, carries 4 passengers and a top speed regulated to 85 mph. Selectra Sunrise is it's make, model. Is that good enough density for you? Can an air powered car do it? What would an air car with these ratings weigh? Could it even be built? With air cars energy/ volume would be the problem too. What is it? The other person was talking about long range. If you only need a 5 mile range air may work. Not good for most people. The one's built in the US were really bad in these points. Some barely went 1 mile and they froze up.

[biofuel] air car primer
negre's aircar is an urban, repeat, urban vehicle. it is not designed or meant to travel on i-95 from boston to ny. it is meant to travel within an urban environment, moving driver plus four passengers. it uses 70 % of the road space, and costs 25 % of what the selectra costs. it weighs 700 + pounds less than the selectra. if we are to constructively compare it to an ev (and i don't see why we can't have both, instead of having to choose between one or the other), we should perhaps compare it to town cars such as the ford 'think' (formerly pivco), or similar. with a full charge of air the range varies between 62 and 186 miles, depending on how fast, or uphill, or heavy, you travel. it can re-charge to 100 % in less than three minutes, which neither the solectra, or any other electric car for that matter, can do. (100 %, not 80 %) it is an alternative, not a magic bullet. just as the selectra, or the think, are alternatives. it is innovative, and affordable. the final decision will be the market's, in which neither the selectra, or the think, have had much success so far. the think has been on trial in california for close to five years now, with little to show for it. the original company, even though it had government support, went belly-up, and ford bought it to re-float the idea, probably as a pr spin. the aircar is 100 % privately funded, and has no direct or indirect connection to any car manufacturer. and the more the market knows about alternatives, the wiser the choice it can make. berating somebody's effort, or ideas, just because they don't coincide with yours, is not my idea of progress. and using information out of context -- as when comparing apples and pears -- is like cheating at solitaire. imho.
