Compressed Air Car
A friend forwarded me an email:
Link is here:zev car The car won't be able to meet US Safety Regulations, but it's interesting: AMAZING AIR CAR FROM INDIA This is the same company which a few months back-invented a car that costs only $2500 new. BUT it's not available in the USA. Why is it that a gasless vehicle that eliminates the reason to buy oil from foreign countries hasn't even been noticed by US manufacturers? How bad can this be for anybody, anywhere in the world -- except, perhaps, for the oil tycoons? The Compressed Air Car, developed by Motor Development International (MDI) Founder Guy Negre, might be the best thing to happen to the motor engine, and people all over the world. The $12,700 CityCAT, one of the planned Air Car models, reaches 68 mph, goes for a range of 125 miles. It will take only a few minutes for the CityCAT to refuel at gas stations equipped with custom air compressor units. MDI says it should cost only around $2 to fill the car up with 340 liters of air! The Air Car will be starting production soon, thanks to India's TATA Motors. |
Thinking about it, it's a good idea. If you can get the range.
no combustion, so less energy loss via heat. I guess it'll sound alot like an air impact wrench, or other compressed air tool. What's interesting, the concern is freezing, because of the expansion of the compressed air. |
The design has been there for a bit! I think some Buses are running on this principle somewhere in the world! The MYT Engine can work on both air and fuel... Interesting for sure!

Imagine an accident in one of those that ruptures a fully charge Tank!!!
|
I really want the MYT engine. The design is mind boggling and it is so capable
|
if they made a 3 wheel version they could sell them as motorcycles in the USA.. Hell id pay the same price or more for a 3 wheel version.. if it came with a air compressor for at home to fill up with .. hell id pay 3500 for one witha home compressor or on board compressor for charging it up..
However .. wouldn't this be considered non powered motor vehicles.. its not using a engine per say..its just kenitic energy.. Also as for the air tank rupturing , i read up on these the air tanks are carbon fiber and if they rupture they cant explode , just crack open and release the air.. may be loud as heck but not explosive.. |

-it has an on board compressor that is plugged in an electric socket, which will take 4 hours to fill an empty tank. It's kinda like a battery that won't wear out. Maybe the gaskets... -there is also the option of filling up in a filling station which would take 3 minutes |
Hello all...
I have included a few clip from you tube about the MDI Aircar... maybe this will help dispel some of the myths i saw mentioned here http://www.youtube.com/watch?v=ztFDqcu8oJ4 http://www.youtube.com/watch?v=QmqpGZv0YT4 |

I sure the car is Legit, but the video producer didn't know what he was talking about. It's not free. I the same webpage i mentioned, annual cost is expected to be $220. That will pretty much from the power used to compress the air. |

However, that van is PRIME for a nice high watt solar array on the roof... one that could help to recharge the system on sunny days while it sits in a parking lot... depending on the system and exposure time.. it could recharge most of not all of the air consumed while it sits... This would not be perpetual motion.. but it could help with the time between top offs of air. And yes the air IS free.. the Method of Compressing it is not. but the annual cost of running a compressor is much lower than the cost of adding petrol... so free?... no.. better?... by far yes.... |

It would be great if they can modify in a way that will allow it to compresses air when you brake. |
This is very cool.

The system really has potential... I am kinda working on my own concept... using some of the ideas I mentioned about power reclamation.. |
You can even add your name to a list for info when they become available! :)
The guys here at work are freaking out now! lol |
Quote:
It a great idea huh... I wonder if they will have conversions available. When my CRX's engine blows up, I'd like to put one in. |

I want one of these things .. Just make it a 3 wheeler and they can sell them her eint he USA.. 3 wheeler 3 seats would suffice great here int he USA.. if they prove to be safe enough as a three wheeler we have a argument for allowing 4 wheelers to be legalized.. Id feel far safer in one of those than a motorcycle .. Plus out of the weather :) |
In L.A., if they compress the air from the atmosphere, then when it's released in the car's exhaust, it won't meet air quality standards. hehe

Only problem I see with it is...
compressed air tanks are big bombs! They'd have to be subjected to the same sorts of design / test / build standards nuclear waste WIPP transport containers are... Wonder how many bars they put in and how big. Major safety issue IMOP |
And a tank full of gas is a big fire hazard! :) Any form of stored energy can be extremely dangerous. This is nothing new. Those tanks can take quite the impact before anything bad happens to them. The weak point is the valve/head. I'm sure it wouldn't take much to create a solid protective cage around it. They do the same for EV batteries, gas tanks, the civic GX's natural gas tank...

United Nuclear - Hydrogen Fuel Systems totally safe... No... compressed air scares the heck out of me... I much rather sit on liquid fuel tank... Empty gas tanks are far more dangerous than full ones but nothing like a compressed air tank... Have a look at welding tanks .... those are what the air tanks would have to look like... and then electric batteries start looking much better! No losses compressing the air either which would need to be factored in .... Air motors are efficient (gas turbines have amazing power to size / weight ) but I suspect electric motors are more efficient ... (longer time to recharge though) |

All other fuels have to mix with air before releasing most of their energy. Even LNG has a relatively trivial energy of compression. Compressed air, OTOH, has all of the energy available instantly, like dynamite. SCUBA tanks are regulated much more stringently than aircraft parts for this reason. If you take one in to be re-filled, and the shop sees a hint of damage, they drill a hole in it, so nobody can fill it.
If this wasn't a stock fraud, I'd worry about whole traffic jams and parking lots going up in a chain reaction. |
The whole concept of using compressed air as a storage medium is not very efficient. If my memory serves, the compressed air only stores about 40% of the (electrical?) energy you put into it. Pretty poor ratio...
And, the tank has to weight a big boatload? How far can a 60-80 gallon tank at 2500PSI take you? And talk about lack of infrastructure; it's almost as hard as hydrogen. |

On a compressed air tank, you could make (a) rather large weak area(s) where it'd tear open in an emergency. |

Gets funky when the fire brigade throws water on it ! |
Where do you get the kind of air pressure to recharge your air powered car and where do you get the energy to run it?
Alot of compressed gas's that are sold are not pumped as much as they are frozen to compress them. Also things like small propane tanks are one time use only because they are so light weight that you are not allowed to transport them, it's a DOT rule not a propane rule, that is why you can get home refill kits for filling them off larger heavy tanks but you will never find a store that will refill your small hand held tank. |
Safety relief valve, eh? An oxygen cylinder got dropped on delivery to my high school, and it wrecked 3 classrooms as a whirling rocket. Somebody was damn glad they had followed the rule about avoiding a school in use.
|
I would imagine if the safety valve was big enough and the tanks were secure you could dump a lot of air at once in an accident and not create a rocket launch.
|
An accident does not leave you enough microseconds to dissipate the energy as anything but an explosion. Sending a rocket straight up would probably be the safest option.

Propane tanks are very low pressure in comparison. You just need enough pressure on the propane for it to change state into a liquid (about 150 psi @ 90F). |

The range of these things is useless. Don't fall for the hype... and especially the ridiculous perpetual motion bull**** I saw parroted on Discovery Channel.
