...impressive array of advanced technologies invented both in Detroit and very far from it. Instead of an internal-combustion engine, for example, the Hy-wire is powered by fuel cells like those used in the orbiting space station. Power is generated by an electrochemical reaction of hydrogen and oxygen that yields as its by-product only heat and H2O. No smelly exhaust, no smog, no greenhouse gases...
...fuel. Sound like a blue-sky pipe dream? One day last July, 300 km above the South Australian Desert, that dream became a reality in the form of the HyShot scramjet. A scramjet (that's top-gun shorthand for "supersonic ramjet") is a jet engine that is powered by oxygen it scoops out of the air as it flies, so it's not weighed down by a fuel tank (though it needs an initial boost to get going). This summer's launch represents the first time a scramjet has flown outside of a wind tunnel. It will take years...
...with charts for hours. His hypothesis is that the Buddhist Lent full moon coincides with the period when the earth is passing closest to the sun. The sun's pull of gravity, he says, combined with a higher degree of UV radiation increases the concentration and volatility of oxygen at ground level that could cause existing methane escaping from the riverbed to spontaneously ignite. "In fact, it's not only one night per year," he insists. "The fireballs occur over several nights in October, and again in May when the earth swings closest to the sun again...
...Under rules instituted by the Rudenstine Administration, students are entitled to an environment free of racism, hostility and threatening speech,” she wrote. “An audience is oxygen to a poet, and the most effective way of showing your feelings is to deprive...
Shiga's most recent book, "Fleep" (Sparkplug Comic Books; 44 pp.; $5), mixes his love of puzzles with the more straightforward kind of story. A man wakes up inside a phone booth encased in concrete. With no memory of how he got there and slowly losing oxygen, he utilizes scientific principles and the contents of his pockets to discover where he is and how he got there. "By my calculations, the rate of torsion on my pendulum indicates my latitude to be roughly 37 degrees - 49 degrees North," is a typical insight. One setback after another must be overcome with...
