A multistage wind turbine or network of wind turbines with improved and optimized wind-directing, wind-shaping, and wind-power conversion features indicates that the shapes of these features directly affect the ability of the multistage wind turbine to use the power of moving air, such as wind, to spin a rotor and create torque on a rotor shaft to generate electricity. The wind-power-conversion mechanical efficiency described significantly improves upon previous designs by conversion of wind energy into electrical power at a superior price-to-performance ratio compared with existing alternative energy technologies.

A power generation system includes a flotation assembly configured to float in water and a first harnessing assembly coupled to the flotation assembly and disposed in an airflow above the water. The first harnessing assembly is configured to harness the airflow to create a first rotational energy. The system also includes a second harnessing assembly coupled to the flotation assembly and disposed in the water. The second rotational assembly is configured to harness movement of the water to create a second rotational energy. The flotation assembly also includes a generating module to convert the first and second rotational energies into electrical energy.

The present invention teaches a vertical axis wind turbine including a base structure; a yaw system secured to the base structure; a rotatable turbine main body secured to the yaw system, a main shaft rotor including a plurality of vertical rotor blades secured to the main shaft rotor for the collection of wind energy located within the turbine main body, and an electrical control system to control the yaw system. The turbine main body includes a single spiral stator having a single vertically aligned opening.

A vertical-axis renewable-power generator is an apparatus that is used to efficiently generate power in various weather conditions using renewable energy sources. The apparatus includes a vertically-oriented foil and a fluid turbine. The foil is designed to generate areas of relative high fluid velocity and low pressure on one side and relative lower fluid velocity and higher pressure on the opposite side. The foil is also self-directing so that the foil can follow the direction of the fluid flow. The fluid turbine is integrated into the foil so that the fluid turbine can be rotated by the high-speed fluid flow. The rotation of the fluid turbine can be used to generate electricity. The apparatus conforms to the Bernoulli's principle that is proven to increase the speed of the fluid flow over the foil, which is used to increase the speed of the fluid flow impacting the fluid turbine.
