Eco Wave Power, an Israel-based company, is set to install the first U.S. onshore wave energy pilot station in the coming months on the port’s Main Channel, next to AltaSea.

Barrier islands absorb wave energy before waves hit the mainland, which can lessen coastal storm surge and flooding.

Researchers report in ACS Energy Letters that simply repositioning the electrode -- from the center of a see-sawing liquid-filled tube to the end where the water crashes with the most force -- dramatically increased the amount of wave energy that could be harvested.
