November 7, 2012 at 14:38A new type of wind generator produces electricity without blades
We are all accustomed to the standard form of wind generators, and with the word wind generator, most immediately imagine rotating blades. Some countries have entire wind farms that consist of many tens, if not hundreds, of “mills”. This method of obtaining energy has advantages, there are also disadvantages. The main disadvantage is usually called noise, as well as the abundance of moving parts. It turns out that there are other, no less effective, methods of generating electricity through the "catching" of the wind. For example, an effective wind generator has already been developed, which generally does not have moving blades.
Such a wind generator, created by the efforts of Saphon Energy engineers, works on the principle of a sailboat. It is designed so that the “sail”, which in the photo looks more like a plate, catches the wind, converting the energy of a moving mass of air into electricity. Due to the pressure of the wind (even a small one), the sail oscillates, facilitating the movement of small pistons located in the upper part of the system.
Pistons, in turn, put into operation a special hydraulic system, which converts kinetic energy into electricity. According to the developers, Saphonian, the so-called system, does not contain either transmissions or a “gearbox”. In addition, such a system practically does not make noise. At the same time, the efficiency of such a system is 2.3 times higher than that of a conventional wind generator. In addition, the cost of maintaining the system in operation is 45% lower than in the case of the traditional scheme of work.
The company has already received a patent (thanks ilya42) for his invention this year, and is now looking for a partner to launch an industrial production scheme for his wind generators. In general, the system is quite interesting. Of course, there are many questions, including the effectiveness of the system in different climatic zones, as well as the power of a wind generator of different sizes.

Machine translation of a patent (French) into Russian
The invention, a description of this technique, is a system for converting wind energy (CESG) into mechanical energy and then electricity.
This wind energy conversion system (CESG), described below, is not subject to Betz's theoretical limit (59%). Thus, this invention provides a performance much higher than wind turbines currently in use.
The system (WECS) has a wheel (F) with a series of blades located around (see drawing No. l). The wheel (F) rotates in an association to rotate around an axis (L) fixed, thanks to the kinetic energy of the wind in the blades, providing the wheel (F) mechanical rotation energy.
Flush to the axis (L), the holder (E) is stiff enough to provide the plate (or back) of the series with double acting cylinders (D). The latter may consist of one or more double acting cylinders (see Figure 1 M 1). To simplify the present system description (WECS) has a series of three double-acting cylinders. Distribution and positioning of the series by double acting cylinders (D) on the bracket (E), to be sure in a very definite way, to ensure better functioning (see detailed drawing No, no l).
Piston rods from a variety of double-acting cylinders (D) are connected to the ball joint (), and in order to provide it with the maximum degree of freedom in space,
allows movement and more fluid to the wind (see detailed drawing No, no l) and (photo No. 7). Said the body (A) has a shape and surface properties are determined, respectively, to achieve an aerodynamic drag coefficient higher and the maximum resulting wind force captured. In addition, the body (A) should have the lightest weight possible. In this case, and not only on part of its surface, it can, for example, be covered with a curtain (see figure No. 2).
In order for the wheel (F) to rotate freely and independently of the body (A), the active surface (the surface facing the wind) is stored constantly exposed to the wind (see front view in drawings No. 3, No. 4, No. 5 and No. 6).
The fastenings on the piston rods with double acting cylinders (D) on the body (A) must be mounted on an axis that coincides with the direction of the vector of the resulting wind force attacks the body (A) (see details Without paying Number l).
The rigid arm © is recessed on one side of the wheel (F) and supported on the other side, pivotally connected to the profile (B) U-shaped C circular motion of the satellite, it turns out, therefore, with the wheel (F), and sliding on the peripheral parts of the body (A) (see figure No. 2). In order to minimize the friction of the sliding profile (B), the latter can be in contact from the peripheral part of the body (A) using rollers and the like. In addition, the peripheral parts of the body (A) must be sufficiently smooth and stiff enough.
When the wind acts on the body (A), the latter rotates under the influence of the moment, the resulting wind force, and from the section of the consolidated (B) and body (A) grows without interference through the Bonds ball, the stems of the double-acting cylinders (D), which are present diametrically in the area opposite slats (B). Rods with double acting cylinders (D) present in the reverse zone (zone side of the profile (B)) are usually drawn (see Figure IM 3).
The presence of a circular motion of the satellite, the profile (B) rotates while sliding to the peripheral parts of the body (A), thereby changing the fulcrum the resulting wind force (connection of the profile rod (B)), which is applied to the body (A). Rods with double acting cylinders (D), therefore, will be drawn and pushed, having a translational motion of the cycle (see figures No. 3, No. 4, No. 5 and No. 6). Thus, the wind energy captured by the wind of the body (A) is converted into mechanical energy of the translational motion of the piston in double acting cylinders (D), thereby creating pressure on the latter.
View from the front, left, top and perspective figures No. 3, No. 4, No. 5 and No. 6 shows the actions of the body (A) on the stems by double-acting cylinders (D) and the behavior of the system (WECS) against the wind at different positions (0 °, 90 °, 180 ° and 270 °) profile (B) peripheral parts of the body (A).
Gondolas (D) are nested to the axis (L). This platform (J) contains mainly a hydraulic motor (H) and an electric generator (G), which can be connected via a speed multiplier (see drawing No. l).
During the back and forth movement of the pistons, a series of double-acting cylinders (D), they grow hydraulic fluid in the hydraulic circuit path (in red) convertible either pull or push, and through a series of valves (see figure No. 7). The latter also allows the hydraulic fluid to be sucked into double-acting cylinders (D) through the hydraulic return circuit (blue), and in one direction "regardless of movement by pulling or pushing".
The hydraulic passage pattern (red) is connected to the input of the hydraulic motor (H). The back (blue) is also associated with the output of the hydraulic motor (H) (see Figure 7). Thus, the flow of hydraulic fluid under pressure turns into rotational motion of the motor shaft (H), which is connected to the axis of the generator (G) through a speed factor, creating such pure electricity (see Figure No. 7).
In order to take into account the direction of the wind held by the system (WECS), it can be equipped with an automatic orientation system allowing it to turn on the mat (I) and hold the body (A) and wheel (F) constantly collide with the wind, and this mode, up or down adrift. In addition, orientation can be achieved using the steering wheel (K), well-defined dimensions, attached using a medium, gondolas (J) (see figure Number l). In order to simplify the work of the orientation system (WECS), and not be limited to the decision of the steering wheel (K) in this case, consider it as a good example.
Thus, the wind energy captured by the body (A) is converted into mechanical energy of the translation rotation and, accordingly, through the rods of the plurality of cylinders (D) and the hydraulic motor (H). This mechanical energy is converted into electrical energy with an electric generator (G). The link in this chain of energy conversion to the conversion of mechanical energy into mechanical energy of rotation can be insured without restrictions, through several other mechanisms, such as crank or other ...
As announced at the beginning of the technical description, the system (WECS) is not subject to the theoretical Betz limit (16/27%) and provides the best wind energy conversion output. The only condition provided by the component is Betz's limit, is that the wheel (F), which has only a small surface area compared to the common active surface system (WECS). In addition, this wheel (F) serves only to change the position of the profile (B) in the circular motion of the satellite and the energy it captures is not required. Consider the energy conversion chain described above, or ultimately recover energy.
