You’ve probably heard of cars that run on gasoline or electricity, but how about only air? Sound too good to be true? Well believe it or not, a company called Zero Pollution motors has devised such a car, and is betting consumers will soon be willing to fork over $20,000 to get one. As reported in the Environmental News Network, the technology has been around for some time and relies on compressed air to power old-fashioned car engine pistons. Although it can only go 60 miles on one tank of air, technicians have engineered a small motor that can pull in air to keep the pressure tank full while driving, and get a whopping 106 mpg to boot. Seems like this company pulled a solution to our energy problems, literally, right out of thin air!
