Generator using the contact potential difference

on 28 August 2012.

The use of power converters are practically fixated on electromagnetic induction. Industry only uses this method. Electrostatic transducers are used only in laboratories or as demonstration units. In practice, they become museum exhibits erroneous paths of development. Electrostatic machine and Van der Graaf Generator - the most famous exhibits of the museum.
       Meanwhile, there are a number of events that allow you to create a fundamentally different power generator. One of such phenomena is the contact potential difference. Never mind that they now seem to us ridiculous, somewhat naive and simple. To some it might seem funny masturbation with a magnet and coil.

          Suppose we have open ring from two different conducting materials. One half ring of material A and the other B. Some of the material ends are electrically connected, for example, welded, riveted, twisted, and is better connected through the galvanometer to observe the processes. The other ends are open. Between the open end varies by touching them one by one, the pendulum of a third metal C, and such that the work function has more than one metal (A), but less than the other (B). Then, the circuit should leak current.

     Contact potential difference is small 1.2 volt. It is independent of the contact area. But here is the magnitude of the current, we can not say this lightly. The current value will depend on the area of ​​contact and the frequency of oscillation of the pendulum.
The mechanism of action is as follows.
      Pendulum (metal C) starts to move, for example, in the direction of metal A. In contact with him some of the electrons with a move to the pendulum, because the work function of the metal C, of ​​which the pendulum more. Then the pendulum leaves the metal A, but as a part of the electrons flowed from him, then he comes off loaded. Moving away from a potential difference between A and C increases (as in a charged capacitor plates moving apart as increasing the potential difference between the plates). But starts induced charge of opposite sign on the metal B. In contact with him pendulum not only gives its full charge, and will return in abundance, so that the work function at C lower than that of B, so that in the induced charge of opposite sign .
      Thus the pendulum of a material with a charge carrier between A and B. The return of the pendulum to the metal Now proindutsiruet charge on it (after all, the pendulum is now full). The pendulum will give him the accumulated charge again in abundance. And so on to the steady state. Work of external forces is spent on moving the charges from a metal to metal B.
 

Figure 1 G-galvanometer (ammeter), A - metal with lower work function, and C - with an average metal work function, in the metal with the highest work function.

      Work on the separation and charge transfer must be done by external forces.

      Any structure with reciprocating inferior designs that use spin. Therefore, the transition to the rotational structures should improve the generator. The rotor of a material with high work function, alternately touching the stator materials with higher and lower work function, will provide high transfer charges and, of course, the best performance. Touch (contact) can be provided by sliding contacts or graphite brushes.

      We can not say with confidence to what section of the museum of electric generators should place the proposed generator using the contact potential difference. Or is it hopeless design or construction, the use of which is possible in some areas. The last point is usually puts the experimenter or the one who creates a successful design.
