...minimize the amount of oxygen necessary to maintain the two-gas atmosphere (44% oxygen, 56% nitrogen) that the student crew breathes, the simulated spacecraft is equipped with a concentrator that pulls exhaled carbon dioxide out of the air. The carbon dioxide is combined in a catalytic reactor with hydrogen and converted into water and methane. An electrolysis system then decomposes the water into oxygen-for breathing-and hydrogen that is used to feed the catalyti c reactor. Reluctant to waste even the squeal of this chemical pig, McDonnell Doug las engineers are working on spacecraft thrusters that can be powered...

"A pale carbon copy," hooted Curley when the book came out. Carbon maybe, but pale never, as critics cheered ( nor's fascinating account of the last campaign of the boss of a big-city machine.

It is a great fire extinguisher, a powerful pesticide, will dry off dew-shorted spark plugs, and is such a versatile solvent that it will vaporize the grease stains out of a dress or tar from the rug in no time...
...wonder that it is used in so many successful commercial products. But carbon tet has its seamy side.

It is especially dangerous for people who have just had a few drinks...
Last month the U.S. Food and Drug Administration acknowledged that there are many solvents and cleaning agents just as effective as carbon tet but less likely to cause serious illness. It began a series of legal moves to forbid the interstate shipment of carbon tet for retail trade. If the FDA's drive succeeds, it will be up to the individual states to stop intrastate sales of a useful but dangerous chemical. One straw in the wind: the U.S. Coast Guard recently withdrew approval of carbon tet fire extinguishers on boats...
