The Aerogenerator X is the conclusion of an 18-month feasibility study called the NOVA project undertaken by Cranfield University, QinetiQ, Strathclyde University, Sheffield University and Wind Power Limited.
The project was funded by the Energy Technologies Institute, a public private partnership comprising BP, Caterpillar, EDF, E.ON, Rolls-Royce, Shell, BP, EDF, EON, Caterpillar, the UK government and wind power developer Wind Power Limited.
John Roberts, head of energy at Arup, said: "Despite the installation of a number of large wind turbines offshore, the problems of increasing capital cost for deeper water remains unsolved as does the issue of safe operability in the marine environment.
"There is a tremendous opportunity for new ideas to make a difference to the commercial viability and operability of offshore wind power."
The new turbine would rotate on its axis, would have a span of around 275m, and has been compared to a sycamore leaf.
American and Norweigan engineers have already started work on similar projects, which could revolutionise the offshore wind industry.
Norweigan firm Sway AS is already testing a 10 MW prototype offshore wind turbine in Hordaland, Norway.
Clipper Windpower, with offices in London and California, is also developing a 10MW wind turbine.
