Wind turbines and sailing ships prove that sometimes clean air is all you need to power a massive vessel. But what about vehicles that don't have sails or wind-catching blades?
Engineers have discovered that when you add a little pressure to the mix, powering things with air becomes an entirely different science.
For years, we've heard whispers about the compressed air car, but nothing has emerged that's practical or appropriate for commercial sale. It may be that trying to design a passenger vehicle that runs on air was putting the cart before the horse, so to speak. That's why we were thrilled to hear of moderate success with a smaller concept: a compressed air motorcycle.
Gizmag has more:
"Benstead's "02 Pursuit" motorcycle is based on the geometry of a current-spec 250 cc motocross bike and uses running gear from a WR250F and Engineair's DiPietro air engine as its power plant. In its current form it can hit speeds in excess of 62 mph (100 km/h) and, given that the first prototype was developed with a focus on design rather than engineering, Benstead believes that performance can be improved with further development."
Although it was designed for use in motocross competition, it's easy to see how success with this air-powered design could lead to its integration into other light-duty vehicles.
Intrigued? We are too. Be sure to follow the 02 Pursuit during its working debut at the Sydney Motorcycle & Scooter Show in Australia on Friday November 25.
