A man is at work one day when...

A man is at work one day when he notices that his co-worker is wearing an earring.
This man knows his co-worker to be a normally conservative fellow, and is curious about his sudden change in "fashion sense."
The man walks up to him and says, "I didn't know you were into earrings."
"Don't make such a big deal out of this, it's only an earring," he replies sheepishly.
His friend falls silent for a few minutes, but then his curiosity prods him to say, "So, how long have you been wearing one?"
"Ever since my wife found it in my truck..."

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.]
