German automation technology company Festo developed the DualWingGenerator, a wind turbine that uses a flapping wing motion to convert power into electricity.
The DualWingGenerator wind turbine consists of a vertical column and two pairs of wings that measure 2.5 meters across. The wings are fitted to sliders and move up and down as air flows across their surface. As the wind blows, the two pairs of wings move in opposite directions. The kinetic force they generate is transferred to an electricity generator to be converted to electricity.
While this wind turbine's output is related to the strength of the wind, Festo intends to use intelligent control technology to lessen its dependence on wind. This technology will enable the system to optimize its operations and adapt to different wind conditions to get the most out of them.
The DualWingGenerator is not yet market-ready, but Festo believes it can eventually be used to generate electricity in buildings.
