...writer and business strategist, and he was also one of its most practical, though not most profound, political thinkers. He proved by flying a kite that lightning was electricity, and he invented a rod to tame it. He devised bifocal glasses and clean-burning stoves, charts of the Gulf Stream and theories about the contagious nature of the common cold. He was a pioneer of do-it-yourself civic improvement, launching such schemes as a lending library, volunteer fire corps, insurance association and matching-grant fund raiser. He helped invent America's unique style of homespun humor and philosophical pragmatism...
...Catholic Church in the U.S. adopted a social gospel that stressed aiding the poor over preaching to the unenlightened, evangelizing at its purest fell to Evangelicals. Rare is the conservative Protestant church that doesn't send its teens off on short-term mission trips or play host to a stream of missionaries on home leave, their stories full of exotic places and changed hearts. Although they would never admit it, the returnees are Evangelicalism's paragons, making its philosophy of relentless outreach their lives' work. Says Beth Streeter, a Moraga, Calif., health-care consultant who left on a short mission...
...case, Dean has unlocked a fairly new and vibrant Democratic constituency that transcends his left-wing peacenik stereotype. It is young, middle class, white and wired.

...Because water is 800 times more dense than air, tide power is a more productive energy source than wind power, now commonly used throughout the developed world. Where a wind turbine may be up to 80 m in diameter, a tidal stream turbine need be only 10 m across to produce 50% more energy. Though the blades turn slowly, just 10 revolutions per minute, the rotation generates a great deal of torque - a force that causes an object to rotate. That is then turned into energy via a hydraulic accumulator, which condenses the power into a motor that drives...
