Until recently, gas was upwards of $4 a gallon. People were going nuts about buying hybrids, smaller cars, and walking or riding bikes. Now that the economy's committed sucicide, however, that recently changed, but oil is sure to go up again sometime. And when it does...MDI will be there.
Check this out. MDI, a French company, has developed a motor capable of what a normal internal-combustion engine can do, that runs on compressed air.
Yes, you read that right.
Compressed air! Imagine pulling into your garage after a day at work, pulling an extension cord out of your glove compartment, and plugging it into the wall outlet of your garage. You come out the next day and the air tank is full and ready to go. You take out the cord, and off to work you go. And this fantasy is only a year or two from now.
In 2009, MDI plans to release the CityFlowAIR, the first in a line of cars that run on a mix of a tiny amount of fuel of some kind (many are available) and a lot of compressed air. It will be sold for around $17,000. Not bad for a car you don't need gas for.
Below are two pictures, courtesy of MDI, that show these new cars.



Personally, I can't wait for these to come out and am deeply interested in them. See more info and more pictures at
MDI's website.
