In this partnership project of the Deutsch-Tansanische Partnerschaft e.V. (DTP) and the Gesamtschule Blankenese (comprehensive school in Hamburg) was about bringing together students from Hamburg and from the school Jongowe on TUMBATU to install 20 small solar systems together. Long-term preparations made by the Gesamtschule Blankenese and the DTP made a learning project possible that touched people through its good and useful solar initiative and the unusual encounter, as well as motivating for them to use of the hitherto unknown solar techniques. The volunteers Annika and Nadine accompanied the initiation and the practical transaction of the project in Tanzania. They also enabled the mutual understanding through ever translating between Swahili and German.
