This led to a pulse of intense steam pressure, known as a "condensation water hammer."

Special adhesives are available for coping with the challenge from condensation water or ice-water.

Also at the complex are underground fresh water tanks and sealed off condensation water tank beneath the tower.

Some of the original, 70-year-old air-driven pumps that clear the tunnels of occasional seepage and condensation water failed.

Desiccant water generators use less energy than cooling condensation water generators, which makes them a technology to watch.

Its success was put down to luck by Desaguliers, writing in 1744, who stated that the use of condensation water had been discovered by accident, and that the valve gear, which made the machine self-acting, had been built from catches and strings by Humphrey Potter, a young lad whose job was to mind it.
