Gangolf Jobb An Ocean Wave Energy Converter A variety of technologies have already been proposed to capture energy from ocean waves, but this one requires a minimum of material, is cheap and robust. Rather than looking at the up and down movements of waves, the proposed method lets the circular water currents beneath the waves directly drive rotors. The novel ocean wave energy converter consists of an array of parallel Savonius rotors with elastic blades, which are arranged to form a plane and are mounted on tensioned axes in a rectangular frame. The diameter of the rotors is small compared to their length, and compared to the height of the waves. The rotors are made of rubber or plastic on a core of aluminium and rotate around tensioned axes of carbon fibres or coated steel. At the ends of each rotor sit small dynamos which transform the rotational movement of the rotors into electricity. In order to capture energy from waves the proposed converter must be positioned right benea

Paper No. 2006-CSS-01 Thomas SEADOG: Pump Technology Wave Energy Converter Mark A. Thomas Independent Natural Resources, Inc. Eden Prairie, MN Kenneth W. Welch Inventor/Scientist Houston, Texas ABSTRACT How do we produce clean renewable energy and fresh water for future generations? Part of the answer lies in new technologies that will transform conventional methods of creating renewable energy. The Seadog Pump is an ocean energy conversion technology that has been tested at the Offshore Technology Research Center at Texas A&M University. This technology solves some of the major problems inherent in renewable energy power sources: storage, low frequency output, and intermittency. Converting the vast power of our oceans into high frequency hydroelectric power is the clean and renewable answer to meeting world energy and water demands. KEY WORDS: Buoyancy Block; Point Absorbing; Power Storage; Desalinization. INTRODUCTION The purpose of this paper is to familiarize the reader wi
