Air-powered go-kart hits the tracks

In the tradition of cars that run on water and air , now there's a go-kart that zips along on compressed O2. Considering that air is (still) free, this project by mechanical engineering students from Canada's Dalhousie University is on the right track.

The air-powered vehicle apparently compares favorably with electric-powered carts. In test laps, the students managed three rounds or just under 2 minutes going full out at 43kmh on two tanks.

But the air-powered go-kart still has some ways to go--literally. It runs out of air quickly, according to its makers. Nothing that time and refinements won't improve. We can't wait to try it out--all in the name of sustainable energy, of course.
