The Kitjito Windpump
Windpumps. Windpower technology dates back many centuries. There are historical claims that wind machines which harness the power of the wind date back to the time of the ancient Egyptians. In Europe the first windmills were seen much later, probably having been introduced by the English on their return from the crusades in the middle east or possibly transferred to Southern Europe by the Muslims after their conquest of the Iberian Peninsula.

The first half of the 20th saw further development, particularly a move toward propeller type wind machines for electricity production. By the 1920's 6 million windpumps were being used in the USA alone and their manufacture and use had become commonplace on every continent.But the glory of the windpump was short-lived. With the advent of cheap fossil fuels in the 1950's and 1960's and the development of pumping technology the windpump became almost obsolete in the USA.

There are manufacturers in several developing countries now producing windpumps. The uptake of wind machines for water pumping, however, has been generally very slow even though the technology is well suited to the demand of many regions of Africa, Asia and Latin America.

Visit the Service learning Portal

Service learning as a teaching method combines community service with academic instruction that focuses on critical, reflective thinking and civic responsibility. Service learning programs involve students in organized community service that addresses local and global needs, while developing their academic skills, sense of civic responsibility, and commitment to the community. Internships offer ways individuals can learn from valuable work experiences while also contributing to the host's mission.

Service learning using Appropedia helps to create an essential knowledge base for the world via learning experiences for individuals and classes. The Appropedia Foundation and the Appropedia community work with universities via service learning courses, as well as service learning programs to create these opportunities. Appropedia internships also offer opportunities for service learning.
