The present invention generally relates to the field of energy generation systems-renewable energywind energy and flowing water energy, more particularly to the fluid turbines. The present invention uses the blockage effect either due to a plate or due to a ground suitably place so that in a distance up to one diameter away from the duct, so that the air is deflected up to 90 degrees and beyond and the flow rate through the duct and turbine is increased, leading to higher efficiency and greater power produced.

A combined omnidirectional flow turbine system includes rotors that are disposed in a vertical position and enclosed in a motionless structure that receives air flows from any external direction which are manipulated by an airfoil to cause the rotors to rotate. The rotors can be connected to a transformation element, which transforms mechanical energy generated by the rotation of the rotors into electrical energy. The motionless structure is a hollow body and it is formed by a support structure and cover, being said interior space adapted to store electronic components, which can be directly supplied by the energy, produced.

A pressure generating device has a housing and a lamellar arrangement with a number of lamellae separated by gaps. The lamellae are manufactured from solar glass. The pressure generating device has a means for converting the solar energy incident through the lamellar arrangement into thermal energy, such that, by this means the air situated in the interior of the pressure generating device can be heated. The pressure generating device has at least one air inlet opening through which air can enter the interior of the pressure generating device and at least one second air outlet opening through which the heated air can emerge from the interior of the pressure generating device.

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.

A heat engine for use in conjunction with a power generating plant, including a turbine section having a number of turbines, a heat exchanger section having a number of modules through which the expanded working fluid of the power generating plant and other sources of heat are circulated, a laminar flow inducing section, and a tower section for providing a pressure differential across the turbines of the turbine section. In use, the heat engine provides the dual function of: heating air to generate an updraft such that air forces its way into the turbine sections to drive the turbines and generate additional electricity; and using incoming colder air to condense the expanded working fluid and cool other sources of heat.

An apparatus, system and method to reduce the contaminate concentration of effluent before discharge is provided utilizing discharge pipes, inlets and outlets. The apparatus comprises a central bore having an internal diameter suitable for a fluid flow, wherein the fluid flow moves inside the central bore through the apparatus, and at least one outlet, wherein the fluid flow exits the apparatus through the at least one outlet, a plurality of inlets for flowing additional fluid to the central bore, and wherein the inlets mix the fluid flow with the additional fluid from the plurality of inlets. The apparatus can further mix the effluent though additional mixing devices and additional devices can be used to recapture energy such as, hydroelectric power from the fluid flow. A method reduces the effluent concentration by mixing for example, by creating a helical flow in the central bore. The system using a control panel to achieve favorable mixing or fluid flow by controlling the fluid flow properties of the inlets.

An elevated or ground level vertical cylinder houses one or more propellers and/or turbines that are rotated by heated air convection within or around or above the cylinder. The rotating shafts of the propellers generate electricity in an area at bottom of or below the cylinder. For added, improved air flow directions and volumes; and, for stabilization of the rotating shaft or shafts, a circular pyramid collar structure is disposed below the cylinder. Heat is directed to the cylinder by a plurality of sun tracking concave mirrors that are positioned in concentric circles at various heights. The cylinder may be composed of concrete, ceramics, metal compounds or other materials and operate with a surface temperature that may range 70 to 1,300 degrees Fahrenheit. An optimized system may be constructed on less than one, one or more than one acre of land that could appear as a park like setting.

Apparatus is provided having one or more SWEGS that may be configured to heat air in a draft power tower arrangement. In a closed loop, cold fluid may be pumped into the SWEGS and heated to a temperature in a range of e.g., 100 C.-300 C., and hot fluid pumped out of the SWEGS. This fluid flows through a heating element (e.g., a radiator or specially designed heat exchanger) that heats the air in the draft power tower arrangement.

An apparatus for extracting energy from a fluid flow including a secondary fluid channel, a fluid driveable generator unit and a primary fluid channel. The primary fluid channel comprises a fluid intake in fluid communication with a throat. The throat is configured to increase the flow velocity and reduce the pressure of the primary fluid flowing through the primary fluid channel and includes at least one plenum in the interior of the throat configured to further reduce the pressure of the primary fluid flowing through the primary fluid channel. The plenum includes at least one perforation through its exterior surface in fluid communication with the secondary fluid channel. As such, the flow of primary fluid through the primary fluid channel draws the secondary fluid into the primary fluid channel through the secondary fluid channel and the perforation and thereby into driving engagement with the generator.

A wind turbine for harvesting energy from both horizontal and vertical wind currents having an open frame structure and a central passage through the structure with at least three wind energy harvesting generally vertically disposed and rotatably mounted blades positioned about the central passage and at least three wind energy harvesting generally horizontal blades projecting radially from the central vertical axis of the device. The open frame structure includes a unique rod and cable central structure offset from the periphery of the frame. In one embodiment, the frame structure is suspended from a rotatable hub at the top of a stationary mast.
