News.com has a piece up looking at a set of gas-powered boots that were developed during the cold war. While the technology itself is interesting, article author Andrew Kramer uses it as a launching point for a discussion of Russia's technological stagnation during the cold war. Outside of military applications, many of the innovative ideas developed in the former USSR during the 80s and early 90s were left to rot on the drawing board. The boots were eventually brought to market, but failed sometime last year. They do, of course, also go into how the boots work: "Taking a step down will compress air in the shoe--as in a typical sneaker, said Enikeev, who was a designer on the project. But then, a tiny carburetor injects gasoline into the compressed air and a spark plug fires it off. Instead of fastening a seat belt, the institute's test runner, Marat D. Garipov, an assistant professor of engineering, strapped on shin belts at a recent demonstration. Then he flicked an ignition switch."
