Fish-Inspired wind farms are 10x more powerful. Vortices systems > [vía @treehugger] #biomimicry

Fluid-dynamics expert John Dabiri uses bioinspiration for coming up with better solutions for water and wind energy. According to Dabiri, schools of fish offer a wealth of insight into setting up better wind farms using vertical axis turbines. "I became inspired by observations of schooling fish, and the suggestion that there is constructive hydrodynamic interference between the wakes of neighboring fish," says Dabiri , associate professor of aeronautics and bioengineering at Caltech. "It turns out that many of the same physical principles can be applied to the interaction of vertical-axis wind turbines." Image via CalTech Dabiri points out that lack of space is a big problem with wind farms because wind turbine blades need a lot of room. If placed too close together, their efficiency drops because of the vortexes created as the blades turn. Vertical axis turbines are an a...
