How about bio gas? The sewers were changed to a fully ventilated system, instead of accumulating pockets of gas that needed to be burned off. Part of the gas was used for heating and cooking; the rest powered a diesel generator that supplied electricity to the whole farm. The only snags are that the gas output is variable as the batch ages and you have to clean out the whole digester after each batch is exhausted. www.viacorp.com /bio-gas.html   (1441 words)

Meridian Engineering & Technology Reference Data Sheet on Sewer Gases Sewer gas is a generic name for the collection of gases and airborne agents that often accompany sewage and the natural processes and reactions associated with sewage processing and the decomposition of organic materials. It is not generated from the sewage, but its concentration in sewer gas may be effectively increased by the removal or consumption of oxygen through other means (i.e., rusting, other forms of oxidation or biological activity). Some components of sewer gas may result in detectable odors, but the odor warning characteristics alone may be insufficient to cause exposed individuals to leave the area. www.meridianeng.com /sewergas.html   (1494 words)

Amazon.com: Sewer, Gas and Electric: The Public Works Trilogy (Public Works Trilogy (Grove Press)): Books: Matt Ruff   (Site not responding. Last check: 2007-11-04) Sewer, Gas & Electric takes place, for the most part, in New York City in 2023 as Matt Ruff explains in his intro: "...just like the present, only more so."

Sewer Genesis One early rejected subplot for Sewer, Gas involved a mailman (let's call him Harry) who set out on his route one morning only to discover that terrorists had rigged an atom bomb in the back of his mail truck (don't ask me why; I never got that far). The connection is not obvious: though Rand held some controversial views on racial politics (she condemned the 1964 Civil Rights Act as "the worst breach of property rights in the sorry record of American history"), race relations were never a fundamental issue for her, and do not figure in her fiction at all. Sewer would, tongue-in-cheek, describe the general state of the world in 2023 A.D.; Gas would feature a resurrected Ayn Rand and a whole lot of philosophical hot air; Electric, the lightning-paced climax, would describe the rebellion of the Electric Negroes. home.att.net /~Storytellers/sewergen.html   (2550 words)
