"Can Floating Turbines Harvest The World's Wind?"

"Ten miles off the coast of Aberdeen in Scotland, five turbines tower over the North Sea.

Each is as tall as the giant towers of Canary Wharf in London's docklands.

Kincardine is the world's largest floating wind farm.

It helps solve an engineering riddle. And its designers believe it shows how offshore wind can become a truly global energy source.

In much of the world, the seabed takes a sudden dive close offshore, ruling out the use of conventional offshore wind turbines."
