A Doctors Lecture

A Doctor was addressing a large audience. "The material we put into our stomachs is enough to have killed most of us sitting here, years ago.
Red meat is awful. Soft drinks corrode your stomach lining. Chinese food is loaded with MSG. High fat diets can be disastrous, and none of us realizes the long-term harm caused by the germs in our drinking water. But there is one thing that is the most dangerous of all and we all have, or will, eat it. Can anyone here tell me what food it is that causes the most grief and suffering for years after eating it?"
After several seconds of quiet, a 75-year-old man in the front row raised his hand, and softly said, "Wedding Cake."

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.]
