The first taps are archaeologically attested "valvulae" of Roman times. This is the type of taps "a male", in which a rotating cylinder perforated to allow or prevent the passage of water.

Following the development-area network of aqueducts that supplied cities and large population, developed a thriving industrial activity linked to the production of valves (valvulae), lead pipes (fistulae), but also tanks, stoves to heat water (boiler), etc. .. In Roman times
totaled some examples of "mixers" like those on display, with which it was possible to deliver cold water or, alternatively, hot water. The mixing of the water at the desired temperature occurred in the lower basin, while the bath water came out cold or hot.

With the end of the collapse of the Roman aqueducts, medieval and modern in the taps were used primarily to regulate the flow of liquids from containers.
It was still taps "a male" parallel, but the size was usually reduced. In fact, they were applied to small vessels in wood or metal (ewers, samovar, etc..) Suspended or transported as needed, or in small tanks on the wall.
Quite often, in major churches, was the use of placing a tank, fitted with two taps on a large sink, for liturgical use.
Sometimes, when they were applied to large barrels for wine and beer taps were substantial enough.

The invention of the screw tap is attributed to the English merchant Thomas of hardware Grill in 1800. With this device it was possible to graduate, for the first time, the water flow.
This system, still used today, found wide application, especially with the connection of homes to the mains water supply, as it offered better sealing performance under pressure.

In 1975 he began marketing the first lever mixer with ceramic discs. Previously had been studied and marketed based on thermostatic mixing different mechanical technologies.

The screw tap and the one male were not, however, supplanted by the mixer with ceramic discs.
The male system, in the best shape of male cone or ball, is still widely used both in wine and in various applications of valves for the distribution systems for liquid and gas.

Hydraulics and science fiction Dune

All scientists agree that the availability of drinking water is a major problem in the future. This issue is so hot he could not escape the authors of science fiction, that branch of literature that tries to imagine the future, anticipating problems and social dynamics.

precisely the problem of access to water is at the center of one of the most famous science fiction sagas: the Cycle of Dune. Herbert's novels are in fact set on a planet totally desert, Dunes, where to find and exploit every source of water is essential. The inhabitants of the planet are forced to move even when wearing special suits that minimize the loss of moisture and recycle the water expelled from the body.

What not everybody, even the readers of these novels, they know, is that in Dune there is a lot more science than science fiction. The author, Herbert, before starting the writing of books has indeed studied the more arid regions of our planet, working with scientists at the forefront to combat desertification and engaged in the study of the exploitation of water resources in extreme areas. Almost all the systems described in the novel with which the inhabitants of Dune their supplies and conserve water are actually used in Arabia and in areas at risk of desertification in the United States. The same science fiction suits the natives of Dune prototypes actually derive from the study.

short, the planet Dune is not light years away, indeed it is already here on earth.
