Small wind energy plant
Compared to fast rotating small wind energy plants with 3 rotor blades, multi-blade slow rotators produce almost no noise or hectic shadow flicker, but have been significantly less efficient so far. Using new technology and materials, the University of Applied Sciences Wuerzburg-Schweinfurt developed the "OptiBine", an optimized slow-rotating wind turbine to approach the efficiency of modern 3-blade systems. A "moving" wind channel was simulated by mounting the OptiBine on a train.
