Friedman is locked into reverence for technology, sometimes at the expense of common sense. He conjures up a house so “smart” that its room lights are triggered by motion sensors; a central monitoring device is in constant contact with the local public utility, automatically reducing consumption at peak times; the house generates its own energy from wind and the sun; and “when the sun is shining brightly and the wind is howling” the house’s energy-brain will turn on your dryer, finishing up your laundry.
McKibben asks: “Does it ever occur to him, in the grip of a fantasia like this, that if the sun is shining brightly, or the breeze is blowing steadily, you could dry your clothes on a $14 piece of rope strung off your back deck, or for that matter on a foldable rack in the apartment hallway?” Friedman’s smart house is more benign version of the much-hyped hydrogen car, in other words: They’re both sexy and a long way off, while there are other, simpler solutions already at hand.
