Several devices that generate electricity from the movement of waves are about to begin large-scale testing in Hawaii. In a shipyard in Portland, Oregon, a massive new energy generating device is nearly complete. In mid-May, it will begin a three-week journey to Hawaii for the first large-scale test of the tech connected to the grid. Months later, two other new technologies will also head to Hawaii to begin their own tests. It’s one step toward wider adoption of a form of renewable energy that doesn’t yet exist commercially: waves.Read Full Story.
