Sie ist die älteste und "sauberste" erneuerbare Energie. Doch das Potenzial der Wasserkraft schien in Deutschland ausgeschöpft, Großprojekte in Entwicklungsländern stehen wegen des starken Eingriffs in die Umwelt in der Kritik. Forscher der Technischen Universität München (TUM) haben nun ein Kleinwasserkraftwerk entwickelt, das mehrere Probleme auf einmal löst: Es ist so einfach konstruiert und damit so kostengünstig, dass es auch an geringen Gefällen rentabel arbeitet. Außerdem versteckt es sich in einem Schacht, sodass Landschaft und Gewässer geschont werden. Die Kraftwerke könnten an Tausenden ungenutzten Standorten in Europa und in bislang unversorgten Regionen weltweit Strom produzieren.
