Development and Experience

Our non-profit association Green Desert / OPENWIND-KUKATE uses the experience of many thousands of hours of development work. The “Wind Energy Working Group” led by Prof. Dr. Crome in Bremen aims to provide people with the knowledge they need to build, operate and maintain small efficient and durable wind pumps.

Own water supply concept
So that the Therefore, the water self-supply concept developed in our working group fulfills four criteria of an economically, ecologically and politically adapted technology and agriculture:

  • Small size
  • simplicity
  • capital-cheapness
  • non-violence.

Medium technology for own water supply

Our adapted technology will be in harmony with local, cultural and economic conditions wherever it is realized. It thus takes into account the socioeconomic, material, and cultural resources of the community. Such a technology is functionally and in its immediate application environment of a small-scale agriculture optimally adapted to the practical task of an own water procurement:

  • Wind turbines can minimize cultural discord by providing a reliable water supply.
  • The KUKATE – wind turbines can be maintained or controlled by the population.
  • The energy source wind is environmentally friendly and available free of charge
  • Locally available resources are used for construction wherever possible.
  • Locally available resources are used for construction wherever possible.

Perfect building instructions for do-it-yourself
Our research and performance activities shall be integrated and performed locally wherever possible. This ensures the participation of local residents in technological developments and the synchronization of research with local implementations.

We have tailored the design drawings and construction instructions to a production engineering know-how available in most places. Accordingly, we target the required tools, manufacturing capabilities and professional qualifications available there.

Statements describing the KUKATE technology

30 years of development work and experience in self-construction
Wind energy generators of the OPEN WINDMILL concept for power generation were built by craftsmen and students and then optimized on the test field of the Senator for Labor in Bremen under the supervision of Prof. Dr. Cromes. They have been successfully replicated many hundreds of times around the world. The turbine concept of the KUKATE wind energy converters is based on more than thirty years of experience and development work of the Wind Energy Working Group.
  • The successful multi-year test run of the KUKATE34 confirms all the requirements for an extremely reliable water supply.
  • The entire system can be manufactured, serviced and maintained with simple locksmith tools.
  • In the successful construction of the wind pump prototype, three-quarters of those involved had no prior professional experience in metalworking.
  • For manufacturing, simple skills in the field of metal construction are enough.
  • All parts are transportable by humans.
  • The plant can be mounted lying down and then erected by people.
  • All components are 100% recyclable and do not pollute the environment.
  • The height of the mast and the pump is adaptable to local conditions.
  • The foundation can be built depending on the location. Concrete is not required for the sleeper foundation.
  • In low wind areas, the rotor diameter can easily be increased.
  • KUKATE water pumps do not require gears, belt or chain drives.. Only for the electric version of the KUKATE34E they are mostly useful for generator adjustment.
  • The wind turbine has no electronic, electrical, pneumatic or hydraulic components
  • The piston diameter at any time adaptable to well pipes on site.
  • The piston and valve seals are easy to make and replace yourself.
  • The KUKATE34M diaphragm pump does not require piston seals.
  • Depending on the pumping depth and the pumping requirement of the water, a maximum water delivery adapted to the conditions can be installed via the adjustable crank swing stroke and an adapted selection of the piston diameter.
  • The guide bearings for the hardwood piston rod can be easily replaced at any time.
  • The connecting rod bearings are simple pillow block bearings available on the market worldwide.
  • The gondola bearings are self-made and can be replaced.
  • Power and speed can be controlled via the variable control weight.

And last but not least:
The KUKATE34 wind pump is an ideal useful education and training project for metal professional education all over the world.

 

Material and tools available everywhere for the construction of the KUKATE34

Specifically, the wind pumps can be made and assembled with angle iron, flat sections, pipes, sheets of steel and aluminum, round material of iron and brass/red brass/bronze (for bearings), welding materials, screws, six pillow blocks, wood and leather (for piston seals), and some springs/rubber slips and long ropes.

Experience has shown that countless metal workshops all over the world have tools and apparatus that can process the materials listed above and thus build a KUKATE windmill: Welding equipment, metal saws, a upright and some hand drills, usually a lathe, screw clamps, measuring devices, and typical metal hand-working tools.

They may be construction locksmiths, small shipyard or agricultural machinery repair shops where the KUKATEs are manufactured.

Hurricane proof wind water pump

Safety:
The wind turbines can safely withstand storms up to wind force 12. Calculated with a safety margin, they survive hurricanes up to over 180km/h. The ingenious control and side vane system allows the operating points of the pumps to be adjusted. When the nominal power is reached, the rotor is turned more or less out of the wind direction with the help of the vanes, depending on the wind force (see 2.5.3).

Proven on hundreds of thousands of wind pumps and wind generators for over one hundred and fifty years.

Building instructions, technical drawings, parts lists and tool lists free of charge

In order to be able to use the free regenerative energy of the wind, we offer four data sets consisting of the building instructions, the technical drawings, the parts lists and many photos for promising do-it-yourself construction:

KUKATE-rotor concepts

Wind energy use for self-builders with a guarantee of success
Here we present KUKATE OPEN WINDMILL construction plans for three different types of wind power:

We have presented details and technical details about the rotors in detail under KUKATE rotor concepts. We strongly recommend you to study the corresponding explanations there.

 

These three success guaranteeing building instructions are for the construction of wind turbine rotors with 3.4 m diameter.
You will achieve with them a wave power of about 500W at 6-8 m/s wind speed.

Depending on the type and your own variation, you can make these rotors work for you. We recommend that you mount the 40 mm shaft made of round steel in pillow block bearings that are standard worldwide and design the rear bearing as a locating bearing.

 

Own variants for customized applications
Our design concept allows for any number of our own wind turbine design variants. The design, the number of blades, the rotor diameter, the type of mast and the application will – we hope – be very different.
If you want, you can use the super stable mast of the KUKATE34K for all rotors and also the 100 000 times proven alignment of the rotor with the control and side vane. But also guyed tubular masts with a slewing ring for the nacelle can be an ideal solution. For this purpose, you can refer to the KUKATE construction plans by Professor Dr. Horst Crome, which are offered on the website www.windenergie-technik-crome.de.
