We have the responsibility for our next generations such as grandchildren and their descendants to develop sustainable energy resources, such as wind power for the benefit of future generations. If we can discover a better solution for offshore wind farms in the deep sea, we need not use nuclear energy. The Fukushima offshore wind power plant has introduced a horizontal axis wind turbine (HAWT). However, is HAWT the right technology for off shore deep sea wind farms? Perhaps not!! A requirement for an alternate solution should be that the axis of rotation of the windmill and buoyant structures should share the same thing. Only vertical axis wind turbines (VAWT) could meet this requirement..Darius, Line Darius, and Line Darius with Flip-up Mechanism are examples of high speed VAWT. The weak point of VAWT is the low torque in low wind velocity. The author made a prototype of a movable leading edge slat (MLES) last year. VAWT with MLES could generate 1.9 times more torque compared to VAWT without MLES at low wind velocity. The author proposes the self-stable VAWT with the flip-up mechanism and MLES for deep sea locations.
