Abstract
We have the responsibility to develop sustainable energy such as wind power for the benefit of future generations. The accident at the Fukushima nuclear power plant has made it clear that nuclear power is very difficult to control and alternatives to both nuclear power and fossil fuels are essential. The prime candidates are renewable energy sources such as solar power and wind power. Seventy percent of the earth’s total area is ocean, of which about 64% is deeper than 200 meters named offshore. Those deep sea areas have not been utilized until now due to some technical challenges. These expansive ocean areas could be a major energy resource in the future. If we can discover a better solution for offshore wind farms in the deep sea, we need not use nuclear energy. The author as developed some concepts and prototypes over the past 10 years. This paper shows the concept of offshore wind turbines with self-stable VAWT with flip-up mechanism and triangle combined floating structure with flexible rectangular link mechanism for deep sea locations.
