18-06-05. I'm not sure which category this belongs. It's called a barge so I posted it here. Apparently a world first prototype this barge will be positioned off the Port Kembla Harbour Eastern Breakwater. It will produce electricity by the action of the waves passing through it. It is to be connected to the state power grid. I'm told it can produce enough power for 500 homes! The barge is waiting for a third attempt to position it at it's proposed location.
