Water Rocket - Hot Water Rockets

Hot Water Rockets

A hot water rocket (or steam rocket) is a water rocket which uses hot blast water as its propellant. Water is kept in the rocket under pressure, at below its boiling point at that pressure. As it exits through a rocket nozzle, the pressure drops and the water instantly boils and expands against the nozzle and this greatly increases the exhaust speed and thrust.

The idea of such rockets was conceived by Germany before the Second World War, with the suggested use of an alternative rocket engine for launching fighter jets.

Famous quotes containing the words hot water, rockets, hot and/or water:

    As a bathtub lined with white porcelain,
    When the hot water gives out or goes tepid,
    So is the slow cooling of our chivalrous passion,
    O my much praised but-not-altogether-satisfactory lady.
    Ezra Pound (1885–1972)

    The Thirties dreamed white marble and slipstream chrome, immortal crystal and burnished bronze, but the rockets on the Gernsback pulps had fallen on London in the dead of night, screaming. After the war, everyone had a car—no wings for it—and the promised superhighway to drive it down, so that the sky itself darkened, and the fumes ate the marble and pitted the miracle crystal.
    William Gibson (b. 1948)

    The fact that the mental health establishment has equated separation with health, equated women’s morality with soft-heartedness, and placed mothers on the psychological hot seat has taken a toll on modern mothers.
    Ron Taffel (20th century)

    Compare society to a boat. Her progress through the water will not depend upon the exertion of her crew, but upon the exertion devoted to propelling her. This will be lessened by any expenditure of force in fighting among themselves, or in pulling in different directions.
    Henry George (1839–1897)
