Schooling Fish Offer New Ideas for Wind Farming

Popular Articles

The quest to derive energy from wind may soon be getting some help from California Institute of Technology (Caltech) fluid-dynamics expert John Dabiri — and a school of fish.

As head of Caltech’s Biological Propulsion Laboratory, Dabiri studies water- and wind-energy concepts that share the theme of bioinspiration: that is, identifying energy-related processes in biological systems that may provide insight into new approaches to — in this case — wind energy.

“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.”
