Hi Albert Kunihira,
Thanks for your enquiry regarding Wind power pumps. Wind Empowerment is an association of member groups around the world building and installing a particular design of electricity producing small wind turbine. We do not at this point have certified products for sale however several of our member organisations have worked with wind pumps and may be able to help you.
Comet Me have designed and installed vertical access mechanical wind pumps which you can see videos of here:
Jorge from Minvayu is working with electric wind pumps in India:
Here is an Indian company making good mechanical wind pumps
Andreas may know of an Argentinian Wind Pump Manufacturer
You could also consider using Solar pumps. The maps below show the wind and solar resources in Uganda. The top map (wind) shows there to be mostly low wind speeds throughout the country, whereas the bottom map showing the solar resource indicates an extremely high solar resource in most of the country.
For more wind and solar data see
http://irena.masdar.ac.ae/. The Wind Empowerment Market Assessment Working Group is developing a methodology for assessing the viability of wind power on a countrywide basis using resource data such as the maps below. Contact
isabel.ru...@gmail.com for more info.
I hope that has been of help, and best of luck with your mission to irrigate in Uganda!
Aran Eales, Wind Empowerment
