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 ...
1. A renewable energy extraction device for river application, comprising: (a) an inlet compartment, with a relatively large opening and reducing cross sectional area in the flow direction, capable of capturing all or a portion of the river flow rate, and increasing speed of the captured water as it flows through the inlet compartment;(b) a high-speed flow compartment which receives high-speed flowing water from the inlet compartment;(c) an energy extraction component including a wheel rotor, wheel structure, and multiple paddles to extract energy from t...
