Compressed air has been one of the fields “in vogue” a few years ago (namely, four or five), ever since the invention of the DiPietro motor and the dreams of a French company called MDI Cat. However, the DiPietro air motor is now owned by an Australian Company, EngineAir, who gave one unit to Dean Benstead, who built a prototype motorcycle with it.
Although this area of automobile science abounds with skepticism, especially from the outsiders, Benstead says that the Yamaha WR250R he retrofitted to run on compressed air can go up to 100 kilometers on a “charge,” and that it’s only a matter of seconds to get it from empty to full, with a proper air compressor.
