Abstract: An unevenly loaded turbine rotor blade is disclosed herein, the blade including a power-extracting region adapted for radially-varied (relative to the axis of rotation) power extraction per mass flow rate. The pitch and/or shape of the airfoil at a first radial position may be configured, so that power extraction per mass flow rate at the first radial position is different than power extraction per mass flow rate at a second radial position. Thus, the power-extracting region may be advantageously configured to take advantage of a non-uniform flow profile across a rotor plane such as may be induced using a shrouded turbine.

Abstract: Betz's law establishes an efficiency limit of 0.59 for wind turbines. Increasing turbine output power requires making the blades larger thereby increasing the radius of the turbine, which increases power by that factor squared, or by increasing the velocity of the air which increases the power according to that factor cubed. It would be beneficial to provide a wind turbine that overcame some of the disadvantages of prior art horizontal and vertical turbines including but not limited to, installation infrastructure, operation in non-laminar flow environments, operation over a wider range of air velocities, operation in low air velocity that defines many regions of the world and continental United States, and capable of supporting installations over a wide range of instances from discrete residential/commercial installations to large wind farms as well as providing increased output power through increased air velocities generated within the turbines.

Abstract: The invention provides wind energy use. One application provides wind energy use for water harvesting from natural humid air. The method is based on changing thermodynamic state parameters of ambient wind air portions passed through a device comprising convergent-divergent and wing-like components. Those components transform the ambient wind portions into fast and cooled outflowing air portions. A decrease in static pressure and temperature triggers condensation of water-vapor into water-aerosols. Another application of the method provides an effective mechanism for harvesting electrical energy from naturally warm air using renewable wind energy, including the wind inertia, internal heat, and potential energy stored in the air mass in the Earth's gravitational field. The electrical energy harvesting mechanism is also applicable to use of natural renewable energy of streaming water.

Abstract: An ambient wind Accelerating Wind Turbine is disclosed which exceeds the efficiency of prior wind turbines. Unique venturi with diffuser-injectors concepts are employed to speed up ambient wind flows into a high speed propeller for power generation improvements of 75% or greater. Applicants preferred Accelerating Wind Turbine embodiment comprises; an aerodynamically contoured venturi turbine shroud with a compression venturi inlet section; a ring of rotating blades, (i.e., a propeller) ; and a rear vacuum venturi section; with diffusers-injectors strategically placed in the venturi to ensure the smooth flow of accelerated air through and rearward of the venturi.

Abstract: A miniature hydro-power generation system includes an outer housing and an inner housing. The outer housing may receive a flow of liquid flowing in a first direction at a predetermined range of pressure. The flow of liquid may be decreased by a predetermined amount of pressure and increased by a predetermined amount of velocity and channeled to a hydro-generator included in the inner housing with an inlet nozzle. The flow of liquid may be channeled with the inlet nozzle to flow in a second direction that is substantially perpendicular to the first direction. Upon transfer of kinetic energy in the flow of liquid to the hydro-generator, the inner housing may rotate in the second direction. The flow of liquid may then be channeled back to the first direction and out of the housing with an outlet nozzle. The outlet nozzle configured to increase the pressure and decrease the velocity of the flow of liquid to minimized non-laminar flow characteristics.
