A man who was having heart trouble went to the doctor to see what his options were. Naturally, the doctor recommended a heart transplant. The man reluctantly agreed, and asked if there were any hearts immediately available, considering that money was no object.
"I do have three hearts," said the doctor. "The first is from an 18-year old kid, non-smoker, athletic, swimmer, with a great diet. He hit his head on the swimming pool and died. It's $100,000. The second is from a marathon runner, 25 years old, great condition, very strong. He got hit by a bus. It's $150,000. The third is from a heavy drinker, cigar smoker, steak lover. It's $500,000."
"Hey, why is that heart so expensive? He lived a terrible life!"
"Yes, but it's from a lawyer. It's never been used."

Hydroelectricity

In 1889, a hydroelectric power plant generated alternating current electricity which was for the first time made available to consumers at a significant distance from its origin. A 13 mile power line linked the Willamette Falls Electric Co. power plant to Portland, Ore. Two 300 h.p. Stilwell & Bierce waterwheels together drove a single phase, 720 kilowatt generator. It was not the first hydroelectric power plant, for one had been demonstrated in Appleton, Wisc., 30 Sep 1882 with a small dynamo. Rather, it is the use of alternating current that is significant, for this makes possible long-distance transmission that overcomes the problems of direct current. AC generators driven by steam power had been in use elsewhere since 1886.
