Sink a big pipe, crank a pump, and - voilà! - you've entered a world powered by ocean water. Once primed, the pipe acts like a giant siphon, requiring relatively little energy to keep an inexhaustible supply of cold at hand. Already, 39-degree-Fahrenheit water courses through the Natural Energy Lab's newest pipe - a 55-inch-diameter, 9,000-foot-long polyethylene behemoth - at the rate of 27,000 gallons a minute, 24 hours a day.

This I believe: that it is intellectually easier to credit a divine intelligence than to submit dumbly to felicitous congeries about nature. As a child, I was struck by the short story. It told of a man at a bar who boasted of his rootlessness, derisively dismissing the jingoistic patrons to his left and to his right. But later in the evening, one man speaks an animadversion on a little principality in the Balkans and is met with the clenched fist of the man without a country, who would not endure this insult to the place where he was born.

Though people often picture science as a collection of clever theories, scientists are generally staunch pragmatists: to scientists, a good theory is one that inspires new experiments and provides unexpected insights into familiar phenomena. By this standard, Darwinism is one of the best theories in the history of science: it has produced countless important experiments (let’s re-create a natural species in the lab—yes, that’s been done) and sudden insight into once puzzling patterns (that’s why there are no native land mammals on oceanic islands). In the nearly ten years since the publication of Behe’s book, by contrast, I.D. has inspired no nontrivial experiments and has provided no surprising insights into biology. As the years pass, intelligent design looks less and less like the science it claimed to be and more and more like an extended exercise in polemics.

[Dr. Perelman] was stunned by how complete the correlation was between length and score. "I have never found a quantifiable predictor in 25 years of grading that was anywhere near as strong as this one," he said.
