New Scientist has highlighted some of the latest technologies being developed to harness power from the sea.
Companies such as Pelamis Wave Power and Aquamarine Power are already testing prototypes of their so-called wave energy 'harvesters' - enormous machines that can capture the massive potential energy stored within ocean waves.
Pelamis' huge P2 is filled with state-of-the-art computers that allow programmers to control and update its operations on the fly, quickly taking advantage of changes in sea conditions to maximise energy production and increase efficiency.
The proof is in the pudding, as P2 can produce 750 kilowatts of power - twice as much as earlier prototypes.
Aquamarine's Oyster 800, meanwhile, can generate an incredible 800 kilowatts by way of a giant hinged flap that juts out of the water. Each passing wave closes the flap shut like a clamshell, with the resultant hydraulic pressure driving an onshore turbine.
"If you can get that sort of level of performance improvement then the economics suddenly start to look a lot more favourable," says The Carbon Trust's Stephen Wyatt.

The Dragon was designed by Johan Anker in 1929 as an entry for a competition run by the Royal Yacht Club of Gothenburg, to find a small keel-boat that could be used for simple weekend cruising among the islands and fjords of the Scandinavian seaboard. The original design had two berths and was ideally suited for cruising in his home waters of Norway. The boat quickly attracted owners and within ten years it had spread all over Europe.

The Dragon's long keel and elegant metre-boat lines remain unchanged, but today Dragons are constructed using the latest technology to make the boat durable and easy to maintain. GRP is the most popular material, but both new and old wooden boats regularly win major competitions while looking as beautiful as any craft afloat. Exotic materials are banned throughout the boat, and strict rules are applied to all areas of construction to avoid sacrificing value for a fractional increase in speed.

The key to the Dragon's enduring appeal lies in the careful development of its rig. Its well-balanced sail plan makes boat handling easy for lightweights, while a controlled process of development has produced one of the most flexible and controllable rigs of any racing boat.
