Already been done by the French and many others, and to quote myself from the top of the page:

They already have pneumatic cars, running of nitrogen I think. I can't remember, some guy in France (sigh) invented one. Has 3 3000psi carbon fibre pressure tanks under the car which will only rupture in an accident, not shrapnel.

Yeah i read that bit earlier, got any links, I wanna have a look at this, see how it works

Compressed gas, basically one of the few ways you can directly store mechanical energy, is an EXTREMELY inefficient source of energy. On top of requiring challenging containment tanks, the compression systems it takes to fill those 3000 psi tanks are massive and require a huge energy suck from somewhere. Those tanks don't fill themselves for free....

Not practical, stupidly inefficient, never happen on a large scale.

That's because gasoline isn't an option for most people. They have to drive to work and school, etc etc. What do you expect them to do?

This covers the Australian version as well:



Edit: A whole week of driving for only a few dollars sure beats the hell out of $113 for a 2litre Honda. It's not like i'm ever going to go up to the maximum speed of 180km/h+ or anything. As long as it goes to 120km/h i'm happy.

Oh and they rekon they can get 4500km/h on one tank of gas in the near future, if that's not efficient I don't know what is.

Sorry it's compressed air, not nitrogen and the tanks hold about 4500psi.

$4.30 in southern oregon as of last week... Cleaned me out pretty good

Could anyone explain to me how the Australian guys engine works?

$3.65 at Costco, about $3.80ish everywhere else. Upstate South Carolina...

How did upstate SC get cheaper gas than the lowcountry?
We've got the port and gas is $3.83-90(it really does change that much in a 10 mile radius ) Diesel is insane. Like $4.50 a gallon, has really put a hurting on the truckers. My pops has started using 3/4 veg oil to 1/4 diesel in his truck.


To guys in the UK. Yes gas is cheaper here. But you have to factor in the mass amount of travel needed to run the US economy compared to the UK economy. We have alot more open spaces. I'm sure the average Brits fuel costs are alot less than the average American's.

Holy cow.

It was only $4.15 around here, and that's a far western suburb of Chicago -- in the city limits, I've seen it around ~$4.25.

Fuel costs are much higher in Europe in general, but they are also driving much more fuel-efficient cars, and fuel-efficient diesels. We're not quite there yet.

And then you can factor in the general cost of living. I cannot speak for Europeans in general, but I'm positive they get better corporate benefits and compensation (pay) than American jobs on equal terms. That, and well, the US dollar is relatively weak nowadays.

Not to be over-political, but I heard that the democrat congress is disallowing any new drilling that the republicans want. So the prices are being blamed on G Dubya...

Really? I thought it was the exact opposite, though I wasn't following it very closely.

Our cars usually avergae around 50miles/gallon these days. These are mostly the family cars, you won't see any 4x4's doing anywhere close to 30miles/gallon. That's why they're going out of business very fast.

**** Maxus what car are you driving, none of the cars at my house get even close to 50mpg

Ford Mondeo ST220, Dark Blue.
Does 50mpg even on urban runs.
Does 60mpg on trips up to Scotland.
I can't drive yet but it's my dads.

I have a 95 polo, also dark blue, no idea how many miles per gallon it does though, probably around 35 I would think

that's what I'm talking about -- the Ford Fusion, which is in the same class as the Mondeo, gets in the 20's.
