The invention relates to a drive system for interior wind turbines, consisting of a rotatable tower (5) with a rotor mounted at hub height, the generator (16) being located at the foot of the tower (5) on a drive/generator platform (13) and the rotor torque being transferred from above downwards to the generator (16). Particular requirements are placed on such a drive system as the height of the interior wind turbine increases. A steel-wire-cable-reinforced flat belt (18) is used as a transfer element, the ends of which are joined in a particular way to form an endless belt the pretensioning of which is regulated dependent on the properties of the wind, and automatic monitoring is provided which executes an immediate controlled shut-down of the drive system if damage occurs.

A floating drum turbine is used for generating the electrical energy from the kinetic energy of a water stream (sea wave or river flow) that provides the mechanical energy needed to rotate an electrical generator for generating the electricity. The drum turbine is installed on a buoyant skid anchored to the seabed by some chains/ropes to keep it in a fixed position and direction along the water stream. The turbine is coupled to an electrical generator with a power transmission system, and generates the electricity that is transferred to the coast using a cable system floated on the water surface.

An example system comprises an enclosure configured to be submerged in a body of water. The system also comprises a capture device coupled to the enclosure. The capture device includes a rotor shaft and a plurality of blades coupled to the rotor shaft. The plurality of blades are arranged to receive a flow of water when the enclosure is submerged in the body of water. The flow of water causes the plurality of blades to rotate the rotor shaft. The system also comprises a transfer device extending lengthwise from a first end to a second end of the transfer device. The transfer device is mechanically coupled to the capture device at the first end and configured to transfer a torque of the rotating rotor shaft from the first end to the second end. The second end is located outside the enclosure.

The amount of electricity for industrial and civil use is generated from large alternating current generators that are powered by conversion machines (hydraulics, steam turbines, etc. . . . ) to give up this conversion process, we can use some sources that do not need any conversion operation from any source of energy such as light, steam, water, etc. into electrical energy, these sources are known as internal energy generation sources. An external power source such as a battery is used to initially supply power to start the alternator and generator. Once the system is started, the battery does not have to supply power to the system.

The battery can then be disconnected and the alternator and electric motor will work together to generate electrical power. The alternator supplies one part of this electrical power to the water transformer and another part to the specified load devices. The power output of the water transformer is used to drive the electric motor as feedback. This self-powered generator uses internal energy and will produce more external energy than internal without relying on an external power source.

For the success of this process, a power source must be built that generates energy with a performance factor greater than one.

A sail is mounted on a towing carriage that is used for the rotation of a propulsion wheel of the mechanical gear is added. The towing carriage is connected to a strand and the strand transfers the force originated by the sail to the propulsion wheel of the power plant. The sail has the ability of adjustment of its angle position to the direction of the wind, the total exploitation cycle of the wind power generator employing sails consists of the working part during which the sail is moving along the direction of wind.

An apparatus for amplifying rotating force of a wind power generator includes a blade rotated by wind power, a central rotating shaft rotated by the rotation of the blade, upper and lower horizontal rotating units spread upwards or downwards when the blade rotates, upper and lower fastening plates, a vertical rotating unit continuously rotating the upper horizontal rotating unit and doubling the rotating speed of the upper horizontal rotating unit by repulsive force of a magnetic member, a horizontal rotating shaft rotating the vertical rotating unit as the blade rotates, a shaft conversion unit rotating the horizontal rotating shaft by the rotation of the central rotating shaft, a horizontal-rotating-shaft support supporting the vertical rotating unit and the horizontal rotating shaft, a frame unit stably holding the apparatus and protecting the apparatus from external force, and a bearing.

An axial impeller has a tubular housing mounted on bearings for rotation. The housing is capable of engaging a motor or generator directly or through a drive belt. Interior turbine blades are mounted on the housing wall. The blades may be hinged so they can rotate between a retracted position adjacent to the wall and an extended radial position. Rods penetrate the wall to position the blades between retracted and extended positions. When extended, the blades may be rotated to propel a fluid through the housing; and when retracted natural fluid flow is less restricted.
