Disclosed is a renewable energy extraction device and methods for producing renewable energy from flowing air or water. The renewable energy extraction device captures a relatively large amount of flowing water or atmospheric air and increases speed of the captured water or air by decreasing flow cross sectional area in the flow direction. An energy extraction component is used to extract energy of the high-speed water or air and convert it to rotational mechanical energy on a power shaft. A rotation direction control mechanism is used to make the power shaft always rotate in one direction, without coming to a stop, for ocean applications. The mechanical energy of the power shaft is transmitted to an electric generator, pump, compressor, or any other rotary equipment. After extraction of its energy, the captured air or water is released to its original source at a downstream location.
