...Kamen's intentions may be the patent application he filed in late 2000 for a series of self-balancing "personal mobility vehicles." It's known that Kamen and his colleagues have been working for years on a clean, sealed-combustion Stirling engine that could run on any fuel, including hydrogen. The prevailing theory is that Ginger would combine Stirling technology with a stabilizing system pioneered in Kamen's stair-climbing wheelchair. (The wheelchair's code name, by the way, was Fred. Get it? Fred and Ginger.) The newest clues are the names of two websites registered by Kamen-controlled companies...
...bridge that tilts into the air. Robots that crawl under doors. A hydrogen-powered bike and a surfboard that makes its own waves. Among this year's bumper crop of fresh new ideas, here are some of our favorites...
...Force has made it plain it does not want back its 7,600-lb. hydrogen bomb, missing off the Georgia coast since 1958. And it says the bomb--dropped when the B-47 carrying it was hit by an F-86 fighter during an exercise--poses no threat, since it does not contain the capsule required to detonate a nuclear explosion, and is unlikely to spread toxic material. The B-47's pilot, retired Colonel Howard Richardson, supports that account; he tells TIME he did not personally inspect the bomb, but that he was briefed that the capsule...
...year period what it took the internal-combustion engine 100 years to do," says Byron McCormick, director of General Motors' Global Alternative Propulsion Center. For GM and the other leading car manufacturers, it will take investments of hundreds of millions of dollars each to introduce mass-market hydrogen cars by 2010. The target: reduce costs of a fuel-cell engine to $50 per kW for a 70-to-80-kW engine, or about $3,500, the average cost of an internal-combustion engine. (GM's early prototypes stand at 10 times that per kW target.) Toyota Motors will reportedly roll...
...least that's the hope of investors who have lobbed the first of potentially billions of dollars at a simple chemical principle that an obscure British scientist named William Grove discovered in 1839: when hydrogen and oxygen molecules combine to form water, heat and electricity are produced. Tapping that energy, by binding individual cells into what is known as a "stack," could mean efficient, continuous and clean electricity for everything from long-lasting cell-phone batteries to industrial power generators. And although fuel cells have generated buzz at least since astronauts took a prototype into space on Gemini...
