...sawdust, which not only neutralizes smells but also helps speed the breakdown of material for compost. Like many back-to-basics sophisticates, he believes Jenkins' humanure system is more sanitary and more rational than the conventional alternative. "Human waste is a perfectly good source of an important resource, nitrogen," Knutzen observes. "Water is a valuable resource too. Why mix the two and turn all of it into a problem...
...ships use some of the dirtiest fuel on the planet. Ships' bunker fuel is a thick, black sludge leftover from the refining process and has about 2,000 times the sulfur of regular diesel fuel. When bunker fuel burns, it releases a host of toxins, including sulfur oxides and nitrogen oxides, that can lead to respiratory problems and acid rain. Now a better understanding of the health impact of shipping and commercial boats - combined with high oil prices and tighter general pollution restrictions - is sparking what could be the biggest revolution in industrial boating since the introduction of the marine...
...about sodium azide is that it usually saves lives. That's because, according to the Centers for Disease Control and Prevention, sodium azide is best known for its role in air bags. When a car crashes, an electric charge causes the sodium azide to explode and, in turn, release nitrogen to inflate...
...Many would-be bombmakers have suffered severe burns while trying to mix the explosive in makeshift laboratories. For terrorist groups, however, the risks of TATP are outweighed by the advantages. The white, sugarlike powder is lightweight and nearly odorless (the better to evade bomb-sniffing dogs) and contains no nitrogen (foiling scanners that detect nitrogenous bombs). Its basic ingredients - acetone, hydrogen peroxide and acid - are readily available in beauty supplies and home-improvement products. Al-Qaeda operatives have been using the stuff for years...

At the time, agricultural researchers were enhancing crop yields by bombing plants with nitrogen fertilizer. But they eventually discovered that the process made seed heads grow so big they would collapse in the field. Nature seemed to have hit a wall...
