Okay, I’ve been told more than once that I’m full of hot air, but soon, my car can be too! News came out this week that a new car, using compressed air as its "fuel" will be coming soon. It can be refueled via air compressor (which of course uses energy, so even with zero emissions from the car, only half the green equation has been solved), run 120 miles on a "tank" that costs only about $3 to fill up. Man, this beats my Mini! It’ll be a great city car, especially if you can fill-up at home, and if I can hook the compressor up to our treadmill, we can keep in shape while fueling the car! Take a look at the video in the extended post. Via here, and here.
