The Horse 2020/21

Wind is the result of the sun's uneven heating of the atmosphere.  
Warm air expands and rises, and cool air contracts and sinks.  
This movement of the air is called Wind. [1]

Wind turbine [2]

A wind turbine with a rotor blowing wind into energy. The wind causes the rotor to rotate - the "rotational energy" is then converted into electricity with the help of a generator, similar to a bicycle dynamo. From there, the electrical energy goes into the power grid. The height of the wind turbine is very important. The taller the turbine, the more evenly the wind blows and the more electricity can be generated.

Water pump with wind drive [4]

Wind water pumps are windmills designed to pump or transport water using wind, without electricity or diesel. Traditional technical solutions are used here, completely without electronics and computers. Our modern wind water pumps have of course been revised and optimised according to the current state of the art, which is clearly reflected in terms of quality and also in the material. This system has been rediscovered by many farmers, cattle and fish breeders, as it is a self-sufficient method of transporting water. With these systems, you achieve a bit more independence from energy suppliers again.
