  • the device according to the invention worked as follows:
  • the wind rotor 1 rotates relatively quickly and produces a certain amount of power on the drive shaft 2, which should be sufficient to operate the connected units.
  • the freewheel assigned to the electric motor 7 is rotated in its freewheeling direction, so that the electric motor 7 is decoupled in terms of drive from the toothed ring 8 and thus from the rotation of the wind rotor 1.
  • Any electrical power generated on the solar generator 6 leads to the electric motor initially starting up to a certain speed. Only when the idle speed of the electric motor reaches 7 m in connection with the selected gear ratio the corresponding speed of the wind rotor 1, does it additionally contribute to the drive power on the shaft 2.

  • the drive components from wind energy and solar energy will add up, so that a significantly increased drive power is available on the drive shaft 2 compared to the individual components.
  • the electric motor 7 drives the drive shaft 2 all. If the wind rotor 1 is not assigned a separate freewheel, the electric motor 7 also rotates the warm rotor 1. In this way, the Wmdrotor 1 can serve as a flywheel, for example for overcoming in places high frictional resistances in the driven device, which the electric motor could not all overcome without a flywheel.

  • the extraction of water from a river or lake into a higher-lying channel system for irrigating agricultural land comes into consideration.

  • This device works in both directions of rotation. In one direction of rotation it works as a conventional Archimedean screw for pumping water. In the other direction of rotation, the enclosed fluid (air) is pressed under the surface of the water, gushes out of the opening of the tubular screw 60 and thus also serves to aerate the water.

If there is sufficient wind and / or sunlight, the ring gear 72 is rotated and water is supplied via the eccentrically mounted piston rod. The radial distance of the piston rod and thus the stroke is possible by hanging the piston rod in different bores 74. Here the stroke and thus the load can be made available standing wind and solar radiation conditions are adjusted.
  • the present invention enables particularly long availability times through the combination of solar energy and wind energy for the direct drive of a shaft, since a usable drive power is established even at low wind speeds and low solar radiation.
  • the wind power is sometimes not sufficient to overcome the starting friction of the rotor at low wind speeds.
  • Low wind speeds remain unused.
  • Even low levels of sunshine in conventional solar generators mean that an electric motor that may be connected does not start.
  • the drive elements interconnected via a freewheel and acting directly on a drive shaft, namely the Wmdrotor and the solar-powered electric motor, can add up to a usable drive power even if each individual primary energy component is only present to a small extent.
