Move away from dead-end technologies – help!

Since 2008, we – with our non-profit organization Green Desert e.V. – have made it our mission to develop self-sufficient, decentralized and simple technical solutions in the field of water, agricultural and energy infrastructure.
We want to show how to overcome linear dead-end technologies and install circular processes sustainably.
Thereby we focus on the exchange of gained experience and knowledge. We stand for joint and transparent action.
We can’t do it alone. That’s why we’re building a network. This cannot be done without the help of many volunteers.

Our fuel is your commitment
We would like to have many committed people who like our ideas and therefore want to support us.
– They can do this by providing practical help in optimizing the KUKATE and its construction instructions,
– through donations,
– with the translation of the building instructions into other languages,
– with the supplementation and dissemination of information material.

Actively involved!

We have big plans!
We have gained a lot of experience in recent years through our research and development in the field of wind pumps and water management.
We support the “open source” idea. Therefore, we would like to build a forum as wide as possible, which is available free of charge to all people in the field of renewable energy use. We can’t do it alone.
OPEN-WINDMILL is a key to the above goals. With OPEN-WINDMILL we – the inventors and developers of the KUKATE34 wind energy converters – make our trend-setting designs freely available for free.
Having your own access to clean water is a basic right for all people.
