Ocean Power Technologies Inc. said it has received $1.1 million in funding to upgrade and do more testing on buoy off of Windward O'ahu that generates power using sea motion.

The contract is being financed by the Navy, through ocean engineering firm Sound Sea & Sea Technology of Edmonds, Wash.

One of the Pennington, New Jersey-based PowerBuoy systems was deployed in October about one mile off the Marine Corps Base Hawaii in 100 feet of water. The Hawai'i project calls for the installation, testing and grid connection of successive PowerBuoys.
