What:  The PowerBuoy will be used to provide clean, renewable power
        for oceanographic sensor systems to gather and transmit
        information collected at sea. This advanced technology program
        has prospective applications which include vessel tracking for
        homeland security, tsunami warning systems, ocean observing
        systems, and off-shore aquaculture.

       Members of the press are invited to attend the event which will
        offer both photo and video opportunities of the PowerBuoy
