Ecotopia: A Novel

by Ernest Callenbach

Ecotopians are always talking of “integrated systems,” by which they mean devices that cater to several of their ecological fetishes at once. The extruded house system offers a number of examples. Probably the most startling is the bathroom. Ecotopians have put into practice an early notion of our architects, and produce entire bathrooms in one huge molded piece, proportioned to slide neatly into a section of extruded room. It contains all the usual bathroom components, including a space heater. A companion unit, a large plastic tank, is buried outside, and connected by two flexible hoses. This, it turns out, is a septic tank, which not only digests sewage but produces methane gas in the process, which in turn operates the heater! The effluent that runs out the other end is not at all repulsive, but clear and excellent for watering gardens, so that ordinarily the garden is placed adjacent to the bathroom. Sludge is removed from the tank every few years and used for fertilizer. This system may seem disgusting to some, but it has its advantages, especially in rural areas. And when you remember that gas and electric energy in Ecotopia are inordinately expensive (costing about three times what they cost us) it is clear why such an odd but thrifty idea has caught on widely. Another integrated system Ecotopians are proud of is the heat-pump solar heating device; these are especially effective with the extruded rooms, consume no fossil fuel or even water, and require only a small...
