A wind-speed accelerating wind turbine has the wind turbine installed in the nacelle, the nacelle has a front nacelle member having a cross-section area formed so as to linearly or curvilinearly contract from a wind inlet to an installed position of the wind turbine and has a rear nacelle member having the contracted cross-section area formed so as to linearly or curvilinearly expand or maintain the same cross-section area from the installed position of the wind turbine to a wind outlet, and a wind dispersion part or a wind dispersion shape is provided at the wind outlet of the rear nacelle member.

Energy harvesting system, for harvesting energy from renewable resources, including an array of wind turbines disposed along a towering construction, and plurality of laterally outlying ledges branching outwardly in vertically spaced-apart respective levels, alternately lined-up along the towering construction between the wind turbines. Each of ledges includes an upper ledge surface and/or a lower ledge surface, slanted at a slope for deflecting ingoing wind and/or diffusing outgoing wind toward and away from the adjacent wind turbine, respectively. A photovoltaic (PV) solar panel layout is disposed on upper ledge surface, and includes at least one PV solar panel for absorbing and converting solar energy into electricity. The system may include one or more energy storage modules, usually operational for being lifted along towering construction. The towering construction may include wind and solar sensors and may be rotatable, so as to adjust horizontal orientation of towering construction for optimal energy harvesting.

The invention relates to a method of harvesting overhead wind energy with greater efficiency and being better in terms of manufacturing technology and equipment installation. In particular, the invention relates to a method of harvesting overhead wind energy with an equipment system for indirectly catching wind, the method comprises: catching overhead wind; guiding the caught overhead wind downwards; converting the energy of the caught wind into mechanical work to rotate one or more generators on the ground.

The cost of the equipment system for indirectly catching wind is much cheaper than those of the traditional wind electricity pylon.

Open and closed cycle lift force turbines are provided. Illustratively, the open cycle lift force turbine operates in an open cycle environment without heat and/or pressure, utilizing asymmetric pressure distribution on lift turbine blades mainly to generate thrust with the normal component of this lift force, while using the tangential component of this lift force to drive a bypass fan providing additional thrust and to drive accessories, provide control to the fluid velocity, and/or provide motivation of the fluid's flow. The open cycle lift force turbine may be utilized to generate continuous thrust, heat and/or electricity for powering vehicles in any atmosphere. The closed cycle lift force turbine may be utilized to generate continuous thrust, heat and/or electricity for powering vehicles at any speed in any atmosphere or lack thereof.

A diversely useful wind power generation system for use with an existing structure such as a building. The system has one or more wind capture funnels located at a first location of the existing structure such as at or adjacent its roof. An air pressure powered rotor mechanically coupled to a generator at a second location of the existing structure, such as inside or at ground level. A conduit fluidly connects the one or more wind capture funnels at the first location to the air pressure powered rotor at the second location of the existing structure.
