Shaft Power Plant: Experimental Model (IMAGE) Technical University of Munich (TUM) Caption In the shaft power plant design developed at the Oskar von Miller Institute of the Technische Universitaet Muenchen, water drops vertically into a concrete housing dug into the river bed, turns the turbine of a submersible generator, and returns to the river below the dam. This photo shows an experimental model of a shaft power plant -- without the water. Credit TU Muenchen Usage Restrictions This photo may be freely used in coverage of the TU Muenchen.
