A woman took her dog to the vet. She said, "I think my dog is dead". The doctor laid the dog on the table and reached down and took a cat out of a box. The cat walked all over the dog and the dog didn't move. "Yes, your dog is dead," says the doctor.
"How much do I owe you?" the lady asks.
"$345," says the doctor.
"$345!!?" the lady asks.
"Yes. $45 for the office visit and $300 for the cat scan."
A.C. power plantIn 1886, the first commercially successful U.S. alternating current power plant was opened at Buffalo, N.Y. by George Westinghouse. Compared to Thomas Edison's direct currect ventures, AC transmission distance could be increased by miles using transformers at the source for transmission at much higher voltage, which also decreased energy losses. (Earlier in the year, on 6 Mar 1886, he operated an experimental facility, the first AC power plant in the U.S., at Great Barrington, Mass. where he demonstrated transmission at 500 volts for 4000 feet, stepped down to 100-volt for lights in stores. It began generating commercial power two weeks later, but it was shortly abandoned when it became damaged by an accident.) « |
