VIVACE – Vortex Induced Vibrations for Aquatic Clean Energy

Sunday, November 30th, 2008


Most of the sun’s energy on earth is absorbed by water and the movement of water. Michael Bernitsas, professor of naval architecture, has been fighting the destructive effects of vortexes on underwater structures for years. These vortexes are similar to the wind effect that destroyed the Tacoma Narrows Bridge. His devices can produce energy at a much lower flow rate than is required by turbines, and because of their slower movement, they are not likely to harm fish as turbines do. Also, as the devices can be put far below the surface, and will not be an eyesore or interfere with recreation or navigation. “Small vortexes are created when currents flow over a cylinder. This motion causes vibrations which means that there is a lot of energy waiting to be harnessed.” A pilot project will be installed in the Detroit River.

I heard the music when I was on Delancey heading towards the Essex Street Market to buy some arugula. I’m glad I always have my camera with me.
