...itself to the Pentagon's single, simple decoy. The enemy could slip its warhead inside a decoy balloon and deploy it along with a dozen identical balloons, forcing the Pentagon into a futile effort to destroy all of them. The warhead might be cloaked in a shroud of liquid nitrogen, chilling it so that the interceptor's heat-seeking sensors couldn't find it. Chemical or biological weapons might be deployed in dozens of bomblets far too numerous to destroy...
...will get the interceptor into the right neighborhood, but only the infrared sensors can guide it into its target, gently steering it with minithrusters powered by 30 lbs. of liquid rocket fuel. For the heat-detecting sensors to "see" anything, they must be chilled to -330[degrees]F using nitrogen and krypton, funneled to the sensors through a 0.0035-in. diameter pipe...
...billed simply as "Steve the Chem Tutor," apparently well-known in Cabot for his Chemistry tutoring, donated a liquid nitrogen demonstration had been donated by And not to be ignored was a "Billy Weitzel game-worn Cabot Strauss Cup jersey...
Less familiar is the havoc wreaked on the nitrogen cycle. Through the use of fertilizers, the burning of fossil fuels and land clearing, humanity has doubled the levels of nitrogen compounds that can be used by living things. But those levels are more than can be efficiently absorbed by plants and animals and recycled into the atmosphere. These excess nitrogen compounds wash into fresh- and saltwater systems, where they produce dead zones by stimulating suffocating growths of algae. Since the global food system is based on aggressive use of fertilizer, restoring the balance of the nitrogen cycle poses a daunting...
...Ballard Power Systems, gets its energy from hydrogen--the most abundant fuel in the entire universe. Hydrogen, unlike fossil fuels, contains no carbon atoms and thus generates zero carbon dioxide. However, it could produce some pollution, since burning hydrogen taints the atmosphere by rearranging air molecules to form nitrogen oxides and ozone...
