I was watching the tele and the news came on so i just sort of watched the headlines and it was the usual stuff but still they are going on about oil and how its running out and i said to my mum "will they never shut up about this..." and then she replyed in the [its important though way]" its not as if our cars run on air is it"...

and thats when it hit me surly you could power a car with air and i started to think about it and i thought of alot of different things and they where all your basic stuff nothing too complicated and then i realised if im going to come up with something big that might acualy come on i need to be more realistic so i thought about how the current engines work with the fuel being pushed into the pistons which made a small explosion which moved the pistons which in turn moved the crank shaft... when it hit me why not replace the fuel with bursts of air (just like a steam engine) and they would come out of a tank of compressed air.... i then realised how would the air be recompressed and had to sit down and think that on through and i cam up with a rather engeanious but simple idea, all you would have to do is put a pistion aside which powers another little motor and the motor would be used to recomress the air agian... of corse it would have to be stoped eventualy to recharge the starter motor but still i think i could get this to work i might even see if i could make a little go cart or sumthing like that lol ill post some pics if i can


Please Talk excessivly on improvements i could make to my project

There are a three problematic flaws in your plan.

Firstly, you require a car to turn piston to have compressed air forced into an engine forcing down the pistion to achieve lower pressure. Firstly in a normal motor the air is brought in at normal pressure and the exploding fuel increases the pressure. What you want to do is increase the pressure and then decrease it. To do this you need to force the high pressure air in without a motor.

Then you have the added problem of using some of the created energy (if you achieve any, see first point) to recompress the air. You say to solve the problem of the inachievable perpetual motion you "recharge" the engine. Again possible but would result in very little air/energy actually becoming useful. As in motion of the car. These cars would be slower and less efficient than normal cars.

Finally, where does the energy come from to compress the air? My bet is that you say either electricity or something similar. These products also have problems in creating as currently the majority of electricity comes from huge plants buring oil or coal.

To solve these problems you would need to create a differently designed engine to the current combustion engine and desgin on which could work on the principle of compressed air

I agree with mozzer, your system won't work.

The main problem is that compressed air isn't just floating around. To compress it we need to put energy into it, and then we use that energy to drive the car. What is providing the energy to compress the air? As mozzer pointed out... in the end you'll be back to oil.

Also if you use 4 pistions to drive the car and one to power the compressor, the compressor only has enough energy to recompress enough air to fill one piston.

[Albus Dumbledore]

what mozzer and blackster are talking about is all gibberish to me but anyways, from what they say, it wont work, but it would be cool if it were to work, no more gas to buy probably making everyone who supplies our oil over on the far side of the worl go poor...lol seems like a good ideal in some ways but bad in others.

[new-world-order]

The Compresser would be charged by a giro system running off the crank shaft it would be geared to take in anogth energy to power the compresser as needed due to the fact it wouldnt have fuel and even if ti did have fuel what a difference it woulf make think of how much fuel wouldbe saved all you would need is a small generater which can take about 8 hours to run dry from about 3 litres of petrol dont crititise other peoples ideas unless you ahve a better solution you self and albus thanks it is a rather cool idea

besides there is an engine that runs on air as i have found out after googling for acouple hours ill post the blue prints for it and a pic of the engine


dont automaticly asume everything will fail put a bit off faith into things:D

I think that nearly anything should be considered. Possible sources of energy to drive these air compressers may be windmill, water turbines (dam), water mill (like wind mill, under water), solar, geo-thermal, kinetic, microwave.... (ok, getting carried away - Microwave?!).

It is just great to see that there is much thought going into this. The sad fact is that this is only now being seen as a more urgent need. Most of the rest of the world has higher fuel standards for cars than America. It is just terrible to know that a large portion of people (making no assumptions about who posted here before me) are only now interested in these things because fuel is costing more by the day.

If a country could pull together the resourcs to put a man on the moon in less than 10 years time, they could certainly solve some of our energy problems.

I have heard about this car that runs on compressed air... can't remember any other details.

[mozzer]

I still cannot believe that a car can power itself on air that it has compressed itself.

Show blueprints and then prove it. Make the car and I'll be less skeptical.

From what I've read on the subject it requires pre-compressed air to inject. There is you key flaw

well, not sure how all that would work bud but my advice to you is to keep your ideas somewhat to yourself if in fact you wish to pusue something like this. you don't want your ideas stolen and am sure would want the credit if you ever came up with something or even just an idea that would possibly work.

nice name btw. you ever have a girl in your class named "erin" where you had to go by your middle name because you diddn't want to be associated with a girl during roll call? heheh i did

actually, some guy from around Spain had this idea 15 years before you and has his car almost ready for the market

interesting. i went to the site. wonder if they could make something that doesn't look like a bus.

it's good to know though that the gas station attendants wont be out of business selling air for 2 dollars but then i believe they will need to sell more chips and slim jims

soooooooooooo this go cart idea wasn't as far fetched as people thought i see....
