Modeling wave power extraction devices will help engineers identify best design

Written by:

Ocean waves could theoretically generate an estimated 10 to 100 megawatts of renewable energy per kilometer of coastline. Several pilot installations already harvest wave power, and the first commercial wave farm began operating off the coast of Portugal in 2008, but has since been put on hold. Among the dozens of designs for wave power extraction devices, none is dominant or in commercial development. MIT Professor Chiang Mei focuses on power extraction from short waves induced by wind To provide engineers with predictive tools, his team is developing theoretical models for both single-buoy units and arrays of smaller units.
