I LOVE THIS!!! I can't wait till this technology is available stateside. Last night I caught a glimpse of a report about a new car that's powered on compressed air. I looked it up tonight and sure enough it's true. This is far superior to electric car technology because the engine is extremely light-weight, it will travel long distances on a single fill, and will also run about 70 mph (most electric cars are only 30-35 mph). Oh yeah, and it's cheap too. Around $15k. I found this Australian video on YouTube about the MDI Air Car. It's really fascinating. The second half is about a different compressed air engine but it's pretty cool too. This looks like the future to me!
