The Dutch Rainmaker systems are products based on stand-alone wind turbine. Our concept is applied in two ways.
- Air-to-Water (AW); literally makes freshwater from AIR!
The stand-alone wind turbine is placed in rain lacking regions. This system is especially suited for such environments if also devoid of briny, brackish or polluted water bodies. The system’s wind turbine drives a heat pump which is directly powered by the wind turbine’s blades. With the heat pump the water vapour in the air is condensed and collected for domestic or irrigation purposes.
- Water-to-Water (WW); makes clean water from seawater/polluted surface water
Our concept is 
based on a modified “standard-type” windmill in which no electricity is produced but heat by using a heat pump. This heat is used in a “evaporation” process. In this way different water sources such as sea water or polluted surface water can be purified. A relatively small windmill already has a significant capacity and can be used for drinking water, sanitation water or irrigation
