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.

Coastal Notes Coastal Notes covers a broad spectrum of stories, events and developments in which some can be quirky and local in nature, while other stories are of national importance and are on-going, but whatever they are about, they need to be told.

Stories can be diverse and they can be influential, albeit some are more subtle than others in nature, while other events can be immediately felt. No more so felt, is firstly to those living along the coastal rim and rural isolated communities. Here the impact poses is increased to those directly linked with the sea, where daily lives are made from earning an income ashore and within coastal waters.

The topics in Coastal Notes can also be about the rare finding of sea-life creatures, a historic shipwreck lost to the passage of time and which has yet many a secret to tell. A trawler's net caught hauling more than fish but cannon balls dating to the Napoleonic era.

Also focusing the attention of Coastal Notes, are the maritime museums which are of national importance to maintaining access and knowledge of historical exhibits for future generations.

Equally to keep an eye on the present day, with activities of existing and planned projects in the pipeline from the wind and wave renewables sector and those of the energy exploration industry.

In addition Coastal Notes has many more angles to cover, be it the weekend boat leisure user taking a sedate cruise off a long straight beach on the coast beach and making a friend with a feathered companion along the way.

In complete contrast is to those who harvest the sea, using small boats based in harbours where infrastructure and safety poses an issue, before they set off to ply their trade at the foot of our highest sea cliffs along the rugged wild western seaboard.

It's all there, as Coastal Notes tells the stories that are arguably as varied to the environment from which they came from and indeed which shape people's interaction with the surrounding environment that is the natural world and our relationship with the sea.
