A guy walks into a post office...

A guy walks into a post office one day to see a middle-aged, balding man standing at the counter methodically placing ''Love'' stamps on bright pink envelopes with hearts all over them. He then takes out a perfume bottle and starts spraying scent all over them. His curiosity gets the better of him and he goes up to the balding man and asks him what he is doing.
"I'm sending out 1,000 Valentine cards signed, 'Guess who?'"
"But why?'' asks the man.
"I'm a divorce lawyer."

Hydrogen-cooled generator

In 1941, the first hydrogen-cooled electrical generator for outdoor installation in the U.S. was put into operation. Built by the General Electric Company for the city of Glendale, Cal., it was rated 20,000 kW and cost $391,669. It was mounted on an open deck. (The first GE-built, hydrogen-cooled indoor generator started operation started on 12 Oct 1937). In modern hydrogen-cooled turbo-generators, hydrogen is used as a coolant fluid. The stator core is direct cooled with hydrogen, for example, at a pressure of 3-6 bar. The advantage of hydrogen is a high thermal conductivity and lower friction than air-cooled generators, thus more efficient operation, lower fuel consumption, highest output capacity, and lowest operating cost.*
