Electric Throws
In 1820, the French André-Marie Ampere invented the electromagnet and laid the foundations of electromagnetism (the magnetic effects of electric throws current). This property is used in electric throws motors, speakers, recording devices like VCRs, tape recorders, etc. . In 1840, the Scottish clockmaker Alexander Bain made the first electric throws clock. Power is supplied by a battery that powers an electromagnet which is a pendulum swing. He also imagines a central clock could send electrical signals to synchronize many other clocks. This idea will be implemented many years later. By 1900, electricity began to spread (setting up power system). The use of domestic electric clocks is possible. The first practical electric throws clocks were made in 1918 by Henry Ellis Warren, a U. S. utility. They work with a synchronous motor controlled by the stabilized frequency AC power grid. He managed to convince utilities to offer time as a distribution service that the small (but constant) use of the clocks has become measurable. The small investment required to ensure stability is largely offset by the additional consumption generated by the proliferation of clocks [1]. In the 1950s, technological advances allow the development of electric throws watches (including LIP marketed in France). The development of quartz watches in the 1970s condemn this technique. The arm closes a contact plate at time zero of the oscillation, which energizes the coil and gives a slight boost to the magnet at the bottom of the stem. The oscillation of the balance that allows a catch is at the top of it to act on a ratchet that drives the movement.

In addition to the offensive of electric throws vehicles, Volkswagen AG accelerates the movement in the area of ??hybrid models. The new Touareg and Porsche Cayenne Hybrid Hybrid is already on the market. End of 2010, they will be joined by the Audi Q5 Hybrid, and the Audi A8 Hybrid. A hybrid version of the Volkswagen Jetta will be launched in 2012 and 2013 in other models will appear, including the Golf and Passat Hybrid Hybrid . .
