Maruf Karimov, a 15-year-old from Uzbekistan claims to have invented a technique that allows an internal combustion engine to run on compressed air. Because the engine can recharge its air tanks once it's started, it can run indefinitely.
So far, Karimov has been able to start the car and even drive it a few hundred meters, admittedly at a very low speed. His work has been sent to researchers in Germany, where Karimov may conduct future research into improving his design.
