In Fig. 4 shows a vertical section of the device on the surface of the ground or the roof of the building for the selection of wind energy. Unlike previous: the mechanism of energy transfer rotation to the generator and the generator without sealed capsules are below sections.

In Fig. 5 shows the placement of the device in deep water along the river banks with preservation of the fairway. As closer to the middle of the river the water velocity above the left Bank downstream of the hosted device with rotation counter-clockwise, right clockwise. Figures 5 and 9 shows the connecting device of the base and top design for stability devices. Figure 12 obrazuetsa, summed up, is synchronized with the current network and then fed into the network 19 to consumers.

In Fig. 6 shows the placement of the device on the bottom along the shore of a navigable Bay, which regularly occur and tides; Fig. 7 placement of the device in elevated position; Fig. 8 placement of devices on the roofs of buildings of different configurations of Fig. 9 a vertical section of the platform for the selection of the energy of the sea and ocean currents (along its length placed 5 devices); Fig. 10 shows a top view of the four platforms in the sea or ocean, on each platform 15 devices.

The device consists of a shaft 1 of energy extraction, cylindrical sections collected from the upper and lower holders 3 with fastened between the blades 2.

Each blade of Fig. 1 and 2 consists of two connected arcs of different sizes. The blade 2 between the holders 3 strengthened in line with the binding at the outer edges of the outer circumferences of the holders 3, the profiles represent two paired arcs of different sizes convex sides clockwise, at the far point of the smaller arc is located on the outer circumference of the holder 3, its other extreme point is a point pair with a large arc and odnovremenno 1 to the first point, another extreme point greater arc serves as the point of intersection with the chord drawn from the point of its mating with the lower arc angle 90othe last chord counterclockwise, such design of the blades 3 provides maximum flow pressure on the concave side of the blades 2 in their course work and minimum resistance convex sides at the back of the blades 2 in predebate position and respectively rotating the device clockwise when getting it flow from any direction, to rotate counterclockwise enough to turn the entire device or only section, so that the top became the bottom and bottom-top, the blade 2 overlap each other by a Central angle and do not allow useless breakthrough flow between them, he uses a width greater range of devices, depending on the values overlapped each blade 2 of the Central angle and the angle between them, the device has a 5 modifications.

First modification: each blade smaller arc with its chord overlaps the Central angle of 3.75o, large arc with its chord in 11,25othe blades on the Central corner are separated from each other by 7.5otheir number around the circumference of 48.

, large arc with its chord 22,5othe blades on the Central corner are separated from each other on the 15otheir number in circumference 24.

Third modification: the blades on the Central corner are separated from each other by 22.5otheir number around the circumference of 16.

The fourth modification: each blade smaller arc with its chord overlaps the Central angle of 7.5o, large arc with its chord at 45othe blades on the Central corner are separated from each other by 22.5otheir number around the circumference of 16.

The fifth modification: each blade smaller arc with its chord overlaps the Central angle of the 15o, large arc with its chord at 45othe blades on the Central corner are separated from each other by 22.5otheir number around the circumference - 16.

By varying the dimensions of the blades with a smaller arc from the 3o15oand more arc more smaller arc from three to six times and angles offset between the blades in 7,5, 9, 10, 12, 15, 18, 20 and 22.5oi.e. on the corners that are placed in the circle in 360ointeger number of times, with the required angular overlapping lobes each other or, at least, without angular gaps between them achieved the maximum efficiency of the device. When shifting effektivnosti device falls, because when frequent location of the blades, the flow of water or wind when working stroke of the blades are pressed only on their outer parts, too rare blades increases the resistance of their return stroke.

On devices with the specified configuration of the blades and their placement in the holders of the flow of water or wind can come from any side, in Fig. 1 and 2 for ease of description this area shows only one side, they will rotate clockwise when viewed from the top down. To ensure rotation of the device counterclockwise enough to turn their sections.

In Fig. 3 and 4 show vertical sections of the power unit for selecting the energy of water flows and wind with the above devices of three sections with the shaft 1, the holders 3 and implied, but not painted blades. Next, the composition of the aggregates are lower bearings 4, base units 5, United for sustainability grounds adjacent units, generators 6, the mechanisms of energy transfer, rotation devices in the generator 7, the upper bearings 8, structure 9, United units with adjacent units for sustainability, the cables 12, and a discharge of electricity from the generators to the blocks, more is sent to the network users. Gidroenergoproekt is mounted on the bottom 16, vetroenergoparka on the ground or the roof of the building 17. Gidroenergoproekta, Fig. 3, added: attached to the upper structure 9 sealed capsule 11, which houses the generator 6, a sealed bearing 10, through which passes the shaft 7 of the transmission energy of rotation of the device in the generator 6, the lower holder capsules 13, a bearing 14, by means of which the holder is attached to the shaft of the energy extraction 1. At sufficiently reliable attachment of the capsule 11 to the structure 9 of the lower holder 13 and the bearing 14 can be omitted. Finally, in winter, the surface water flows established ice 15.

For ease of maintenance, repair and replacement of gidroenergoproekta placed at the bottom of Fig. 3, the generator 6 in a sealed capsule 11 is placed above the device, and vetroenergoparka, Fig. 4, the generator is placed below the device.

In Fig. 5 schematically shows the placement of gidroenergoproektom along the river banks, so as not to impede navigation. Given that the river closer to the middle of the stronger, in accordance with the flow direction at the right Bank installed device, rotating gidroenergoproekta for the stability of the lower base and the upper structure. Because these units generators are located above the device, the upper structures of the units of the right and left banks, from the units of the left Bank to the right on the bottom and then on the right Bank of the laid cable 12, by which the electricity from the generators of the power unit enters the block 18, where electricity from different units converted, summed up, is synchronized with the current three-phase network 19, and further from the unit 18 is sent to the network 19 to consumers. In Fig. 5 shows also the river 20.

In Fig. 6 schematically shows the placement of gidroenergoproektom at the bottom along the shore 20 shipping Bay, which regularly occur and tides. In the same way as in Fig. 5, one line is shown connecting to the stability of neighbouring gidroenergoproekta lower base 5 and the upper structure 9. Since the generators of these units are located above the device, the upper connection structures and forth on the shore of the Bay is laid cable 12, by which the electricity from the generators of these units is sent to block 18, where it is converted, summarized from different units, synchronized with the existing three-phase network 19, and from unit 18 is sent to the network 19 consumers.

In Fig. 8 schematically shows a possible placement of vetroenergoparka on the roofs of buildings 22 different configurations. To reduce vibration is careful alignment of devices and their foundations are laid rubber bumpers.

For selection of a virtually unlimited amount of energy of the sea and ocean currents proposes the creation of platforms on which is mounted a few gidroenergoproektom. In Fig. 9 shows a vertical section of one of the platforms 23, the length of which placed five gidroenergoproektom with devices of the above described construction of three sections. Specified shafts of energy extraction 1, disc blade 3, mechanisms 7 energy transfer rotation device in the generators and the generator 6. The upper part of the shaft is equal to the height of the platform, so that under the pressure of the flow devices are not valoraciones of the platform. To prevent slipping sufficient is hni and bottom, fixed in the upper and lower bearings 4 and provide stable rotation devices. Lower bearings 4 are sealed. Equipment units, i.e., the upper part of the shaft, the bearings 4, the mechanisms of energy transfer, 7 and generators 6 are placed in the compartments with sealed bulkheads 29, which provide additional rigidity to the platform and its buoyancy in the water breakthrough in any of the compartments. In the bulkheads for the passage of repairmen are sealed hatches. To decrease the buoyancy of the platform and facilitate its dive to the desired depth so as not to impede navigation, the platform is provided with ballast tanks 24. To hold the platform at a certain depth and a certain place it is attached to the bottom of the sea or ocean 16 with the help of cables 25 and anchors 26. For the dive platform at the desired depth, in addition to pumping water in the ballast tank 24, is pulling up to the anchors 26 four cables 25 via installed in a special compartment at the corners of the platform four winches 27, which, if necessary, by otmuchivanie cables 25 allow to ascend the platform for major inspection and repair platform and its equipment. When the floor is anote to her anchor with winch for subsequent towing the platform to the right place. The surface of the sea or ocean is marked by the numeral 28.

As an example in Fig. 10 shows the placement of four platforms, each of which has 15 gidroenergoproektom, electricity from generators to the cables 12 are collected in one place one of the closest to the shore platforms and forth on the combined cable goes ashore 20 in the block 18 and the network 19. The platform provides to build factories and then tow them to the installation site. The dimensions of the platforms and, accordingly, the amount of received energy is limited by the strength of structural materials and the capabilities of the factory and tugs. To reduce friction on the water, protection from corrosion and marine organisms devices have special coatings.
