20080247871 | Self-orienting, linear drive apparatus for harvesting power from the wind - Apparatus for harvesting power from the wind, mounted on a vertical support or pole, has two linear “power harvesting devices” arranged in V-shaped configuration with the apex of the “V” mounted for rotation in a horizontal plane about the vertical support. The two power harvesting devices move under the influence of incoming wind to orient themselves such that the apex of its “V”-shape structure always faces the incoming wind. The power harvesting devices are each provided with blades attached for movement with a linear endless drive conveyor. With the apex of the “V” facing the wind, the blades are oriented to intercept this wind and to cause movement of the conveyor drive to which they are attached. | 10-09-2008 |
20080273974 | Wind turbine device - A hybrid blade wind turbine device formed of at least a pair of straight outer airfoil blades, and a pair of inner helical wing blades, as supported for rotation within a safety protective cage structure, which wind turbine can be mounted in the vertical, horizontal, or other aligned operational positions. The inner helical half wing blades, being preferably somewhat shorter than the length of the outer airfoil blades, act to “regularize” the swirling wind regime flowing through the hybrid wind turbine, so as to maximize the efficiency of the outer airfoil blades. The helical half wing blades can be formed of individual segmented vane segments to provide improved operational capabilities for the overall hybrid wind turbine. To best harness annualized available wind conditions, the hybrid wind turbine can be customized, through modification of the number of vane segments, the selection of the specific shape of the outer airfoil blades, and the specific operational positioning of the outer airfoil blades. Alternatively, the helical halfwing blades can be formed as generally smooth-walled blades. | 11-06-2008 |
20100239420 | HYDRO-POWER PLANT - Disclosed is a power generating system utilizing hydraulic force, and, more particularly, is a hydraulic power generating system, in which a plurality of water receiving plates are mounted on an elongated looped rail floating on the surface of water, thereby allowing the looped rail to be rotated by hydraulic force. To solve a conventional problem in that each of the water receiving plates on the looped rail receives a deteriorated hydraulic force due to the presence of a preceding water receiving plate and results in low use efficiency of hydraulic force, the looped rail is obliquely installed with respect to a water flow direction by an angle of 10 to 45 degrees, and the water receiving plates are installed at a right angle to the water flow direction. With this arrangement, each water receiving plate can receive a predetermined hydraulic force without deterioration of the hydraulic force due to the presence of a preceding water receiving plate, and consequently, the hydraulic power generating system can achieve improved hydraulic power generation efficiency. | 09-23-2010 |
20130202435 | Energy mind will - The present invention has for object to show how to realize a machine allowing to transform fluid energies into mechanical energy, or conversely, mechanical energy in fluid energy, this machine being able to be used as windmill, in air or in water, as vacuum cleaner, in air or in water, as propeller, as pump, in air or in water, this machine having the capacity to produce or to receive some energy, with a volume of much lower the one that one realizes at present with windmill, or conventional pumps, or other hatch current. The present invention will show afterward supplementary versions of the energy windmill, notably by showing various capacities of pales, capable of realizing energy windmill in their version engines, either in their version compressive, or in other words in their version condensatrice or expansive, additional modes of entrance and exit of fluids, notably outside towards the centre, or still by highly-rated rectilinear towards highly-rated hooked, supplementary combinations allowing to realize them in a staged way, and to produce jet turbines or turbines of expansion, various modes of supports of pales, various additional applications, as vacuum cleaner, ventilator, propeller, pump, jet turbine turbines of expansion | 08-08-2013 |
20160061041 | BAND-TYPE FAN STRUCTURE - A band-type fan structure includes a transmission band body and multiple blades. The multiple blades are side by side disposed on the transmission band body along the surface of the transmission band body in parallel to each other. Each two adjacent blades define therebetween a flow way. When the transmission band body is continuously reciprocally moved, the blades are driven by the transmission band body to continuously reciprocally move to disturb the air in the flow ways so as to produce an air volume. | 03-03-2016 |

20140161611 | POWER GENERATING APPARATUS USING FLOWING WATER - The present invention relates to a power generating apparatus using flowing water, which converts the energy from the flow speed of the water for generating power to the rotational power of a rotating shaft, wherein a plurality of blades ( | 06-12-2014 |
20140212286 | Device of a Self-Adjusting Foil Suspension - A device is of a self-adjusting foil suspension in which a foil is placed in a fluid flow, typically a tidal flow. The foil is rotatable around a rotational axis, and the foil is connected by means of an arm to a track. The arm is rotatable around the rotational axis and rotatably connected to the track around a suspension axis at a radial distance from the rotational axis, the suspension axis being parallel to the rotational axis. | 07-31-2014 |
