...exploded in midair on July 17, investigators from the National Transportation Safety Board and the FBI have been scrambling to determine what caused the Boeing 747 jumbo jet to plunge into the Atlantic, killing all 230 people on board. From the beginning, the theories--a missile, an exploding fuel tank, a mechanical failure or possibly even a meteorite strike--seemed almost as confusing as the jumbled pieces of the plane. And then a set of tantalizing clues emerged. Investigators discovered that several pieces of recovered wreckage bore minute traces of chemical explosives. That evidence provided the strongest support...
With the bomb theory fading for lack of hard evidence, the focus of the NTSB investigation has returned to mechanical failure and the possibility that a spark, despite built-in safeguards, may have somehow caused the center fuel tank to explode. Again, the problem is evidence: there is none. Computer modeling--or the simulated explosion of a retired jumbo jet--may be required to buttress the theory...
...Pentagon has been hammered for its evasive handling of the growing problem. Last week's announcement, for example, came late in the evening in a single-page press release, adding fuel to cover-up charges from both vets and Capitol Hill. "Why this took five years to get released is a question I keep asking," said Republican Congressman Fred Upton of Michigan. "How many veterans could have been treated in the last five years if we knew all the facts we know...
...essence of the hybrid is that very little energy is wasted. Not only does the turbine re-spin the flywheel, but so does braking, which in today's cars produces energy that is lost. The same goes for fuel. With a catalytic "combustor" on the turbine that burns gas more efficiently, the power train will produce what is, by EPA standards, "zero emissions." According to the Rosens, the turbo-flywheel combination will at least double the gas mileage of the car in which it is used, produce a satisfying sound not unlike that of a Lear Jet (albeit far quieter...
...program manager for the electric-vehicle program at the University of Texas at Austin, whose group will put a flywheel motor in a commercial bus in Houston next year. Kevin M. Myles, director of the electrochemical technology program at Argonne National Laboratory, who has done extensive work with alternative-fuel vehicles, doesn't think the Rosens have addressed the safety problems inherent in flywheels. A wheel operating at such a high velocity can explode if knocked off-line--say by hitting a pothole--turning high-tech carbon fibers into shrapnel. "In the final analysis, the design needs...
