200 Water Jets: The number and position of the hydrants in accommodation, service and machinery spaces are to be such that at least two jets of water not emanating from the same hydrant, one of which is to be from a single length of hose, may reach any part of the vessel normally accessible to the passengers or crew while the vessel is being navigated. In addition the arrangements are to be such that at least two jets of water can reach any part of any cargo space when empty.
Among German gardens, in addition to those at Hannover, I must stress the Hamburg park called, in the local dialect, Planten un Blomen. There is a "lighthouse" here, ascended by elevator, with a broad view of all that goes on below. One thing that goes on is a color concert, on a lakelet from which 200 water jets fling themselves in air. Colored lights play on them and a musician at a central keyboard, playing music, water jets and lights at the same time, can create 250,000 combinations, keying his melodies to the changing shafts and sprays of color-lighted water. It is a show to make Berlin's Resi (see below, under night life) look to the laurels of its "dancing waters."
The ocean itself is a vast heat engine, collecting and dispersing its energy at its surface in a complex manner that involves a vertical as well as a surface circulation. In vertical circulation, cold water sinks in the Arctic and Antarctic regions because of its high density. At great depths, the polar water follows the contours of the western margins of the ocean basins in moving to the equatorial regions. In general, the earth's rotation causes the polar water to move in narrow jets, but because these jets "leak" continuously, polar water soon finds its way into the central and eastern parts of the ocean basins, and eventually rises to the surface. |
