Huge 60-foot-tall buoy uses ocean waves to create clean energy

Giant buoys over 60-feet tall may one day generate clean energy to feed into local power grids—but making it a reality isn’t as simple as going with the ocean’s flow. To successfully keep the idea afloat, it’s all about timing.

Swedish company CorPower recently announced the completion of its first commercial scale buoy generator demonstration program off the coast of northern Portugal. Over the course of a six-month test run, CorPower’s three-story C4 Wave Energy Converter (WEC) endured four major Atlantic storms and adapted to constantly shifting wave heights. Although final analysis is still ongoing, CorPower believes the technology offers a promising new way to transition towards a sustainable future.
