The Ultimate Computer

The Ultimate Computer stood at the end of the Ultimate Computer Company's production line. At which point the guided tour eventually arrived.
The salesman stepped forward to give his prepared demo. 'This,' he said, 'is the Ultimate Computer. It will give an intelligent answer to any question you may care to ask it.'
A smart-aleck who ran a humor mailing list stepped forward and asked, 'Where is my father?'
There was the soft hum of powerful electronic gear going to the task. Panel lights lit and blinked, and within a couple of seconds the laser printer printed out a piece of paper: 'Fishing off Florida.'
The smart-aleck laughed, 'Actually, my father is dead! It was a trick question.'
The salesman, quickly thinking on his feet, replied that he was sorry the answer was unsatisfactory, but as the Ultimate Computer was precise, perhaps a rewording of the question might work better.
The smart-aleck said to the Ultimate Computer, 'Where is my mother's husband?' Again, the hum of the powerful electronic brain filled the room.
After a moment, the laser printer whirred to life. The paper said, 'Dead. But your father is still fishing off Florida.'

Mercury boiler electric generator

In 1923, an experimental mercury boiler turbine invented by General Electric began generating about 1,500 kW of electricity at the Hartford Electric Light Company's Dutch Point Station*. It was claimed to be more fuel efficient than steam turbines alone. Boiling mercury (354ºC) needed a smaller fraction of the total heat input than for vaporizing water, and it operated at lower pressure causing less stresses in the pipes. After the mercury vapour drove the first stage of turbines, the exhaust heat from the mercury was used to produce steam for a second stage of steam turbines. By 1947, three full-scale plants had been built, but later conventional steam plant efficiency exceeded the mercury/steam cycle, so the toxic design was abandoned.«[Image: schematic of the mercury and steam circuits for generator.]
