The Melbourne-based wave power company, AquaGen Technology, has patented a new technolgy called RigDrive which is a retrofittable module which fits onto an existing floating oil rig to tap into the potential energy of passing waves.

Despite the seeming irony of providing sustainable power to such a non-sustainable industry, the company points out that there are more 400 floating oil rigs burning diesel for their on-board electricity needs and requiring supply vessels, also buring diesel, to refuel them.

AquaGen has a demonstration site for its previously developed SurgeDrive technology at Lorne Pier in Victoria.
