It's not very much better though. Some of us spend most of our time trying to help a technology succeed...rather than most of our time listing all the ways in which the technology is not done...If you were a positive action person, you would spend time promoting EV or some other technology you believe in, if you believe in anything other than burning dead dinosaurs, that is. Here is where you lost my respect: > I.e. Many perpetual energy engines have been designed and they > all perform perfectly 'in theory' and 'in simulations' and the > real devices 'almost' work and only need a little improvement. > They, of course, are impossible and can never work as claimed > but this doesn't stop people from publishing lots of fancy > looking reports and selling a lot of worthless investments. As you know very, very well, this technology is not even *remotely* connected to "perpetual energy"...why bring it up then? Any technology that might, or might not, work, is not the same as a physically impossible technology. It's impossible to have perpetual motion. Using the energy stored in compressed air (where the compressed air was created by either dirty, or hopefully, green energy sources like currents, wind, waterfall, etc) is not impossible, in fact, it is 100% certain that it can propel a vehicle...the only question is, will the range be reasonable...will the cost savings be this or that, will the business plan work, etc but it is irresponsible to trot out the silly old comparison of any and every technolgy you don't like, to "perpetual motion"... > For instance, it's not an independent review of their car as MDI > contracted them to do it. First of all, you haven't seen the full report, so, a little less confidence is warranted on your part as to what the full report does, or does not contain... >It's not a study of the performance of > the car or even the engine as these were apparently not available. > It's a theoretical study based on only one chamber of one prototype > engine and that one didn't perform up to estimates. You can't call soemthing "Theoretical" unless it was *only* calculations. This was not "only" calculations. "This study based on calculations using the thermodynamic properties of air at high pressure was carried out IN PARALLEL WITH an analysis of the results of the 34P01 engine on test bench." Notice "engine" nor "one chamber of one prototype". So the engine "was not available" is not true...they just sad they analyzed the engine on a test bench....yes, they do not have all three chambers, but it's still an "Engine" with one chamber...just not as fancy a version as the final one... These expert engineers also wrote, "Nevertheless the tests permit to evaluate the efficiencies" You forgot to quote them saying also, "In conclusion, the global concept of CAT cars using compressed air PERMITS to drive small urban vehicles" So you ignore this "small" quote by these engineers from none other than the Ecole de Mines one of the top universities... you ignore their quotes about the fact that this is viable, workable technology and go off about perpetual motion engines...really now..! ...And of course it's a prototype since they are always improving their engine models... "Didn't perform up to estimates" is misleading. you make it sound like MDI claimed that they had the 200km range *today*. This is false. They have not claimed that (and you will hear a big press release the day this is achieved) only that is what their ultimate product will have...Their product is not finished in part because people are far too busy criticizing and not getting off their rear ends helping MDI, get money to 1) modify the braking recovery system for fitting to the cars 2) modify the gearbox to fit the MDI cars, etc (see our group for more details)...that investment is needed for those steps. and OBVIOUSLY the car will not have the full range until those are in place... As for the "forecasted" autonomy, yes, of course until better efficiencies are reached, they will not be at their top, forcasted autonomy. It's not like the current levels (75% efficiency etc) are that low...they are a darn good start and the fine tuning needs to be done. Going on and on about this on Usenet won't help...if you're an engineer, or investor, and want to chip in, that would help... Fact is, the experts have looked at it and say this technology is viable. that it still has a ways to go after being funded on 1% of what GM, Ford etc have, is not a surprise..on such a tiny budget..so it will continue to move ahead slowly unless more of us help out so it can move more quickly to the finish line.. Note also "Mrs J. and D. of ARMINES have visited MDI facilities in Carros near Nice, on June 2 and 3. Messrs. Guy and Cyril Negre, and their team have presented the different concepts of CAT cars. The visit has permitted to have a demonstration of the *actual engine prototype* on a test bench." > Why didn't they supply a car, or at least a complete engine? > Is it possible that it doesn't exist? Is it possible that the > real car and/or engine, if they exist, don't work the way the This is funny.. you have obviously not followed this enough to know that ABC news, BBC news, and others have seen, been driven in, and even driven themselves, the MDI cars...so to write about "if they exist" without learning these facts first is very sad... I will let the engineering experts from the Ecole de Mines reply to your quesiton about why they looked at the engine itself rather than one of the many existing and even more many possible body models housing an engine...I suspect the answer is the obvious one..If the engine was not viable, the body doesn't matter, if the engine is (as the conclusion states, it indeed is) viable, then optimizing the best body is secondary and to be done later (and the money arriving for optimizing the braking system for energy recovery is included in that last stage) Where is the apology from the crowd talking about "scams" when MDI publishes a report which admits that certain "optimization" of certain parts still need "significant work"? Where is the apology from the crowd doubting it is viable, after seeing these Ecole de Mines experts state, right after the preceding statment, that, "Nevertheless, the global concept permits a significant autonomy of the MDI compressed air car" ? I've posted here to encourage investors and people who want to see this succeed, help this technology be completed. Not to argue about it. Get on the yahoo group if you have questions or want to discuss. Or else, post about EVs or other technologies you believe in more News flash: I'm not getting paid a salary to reply to every single post, I have better uses of my time, especially when 9 tiems of of 10 the answer is seen by going on the Yahoo group, or the Yahoo group's file section, or the MDI websites, or the report read carefully and fully. Thus limited time on MDI is best spent helping it. I don't mind replying to a few other questions but not this nonsense about comparisons with "perpetual energy engines" Have a green day...
