| 168 | Wind turbine comprising a planetary gear | US10474137 | 2003-10-02 | US20040105753A1 | 2004-06-03 | Mogens Christensen |
| A wind turbine with a rotor, a nacelle and a tower. The nacelle comprises a planetary gear (4) with a planetary holder (5), on which the hub (6) of the rotor is rigidly secured, and which can be connected to the shaft of an electric generator. The planetary gear (4) comprises a ring gear (7) fixedly mounted on an engine frame (9) in the nacelle or on the member (8) rigidly connected to said frame. The planetary wheels (17a, 17b) of the planetary gear can run around a centrally arranged sun wheel (14) while engaging the latter. The sun wheel is optionally connected to a parallel gear (30). The planetary holder (5) is rotatably mounted in the ring gear (7) by means of at least two sets (17) of planetary twin wheels (17a, 17b). Each set of planetary twin wheels is mounted on a bogie shaft (19) on the planetary holder. Through an axially rearward collar (23) projecting beyond the ring gear, the planetary holder (5) is also rotatably arranged on the curved outer side (7b) of the ring gear (7) by means of an outer radial-axial-roller bearing (27). As a result, a wind turbine is obtained which is suited for generating very strong power and which is very compact and ensures a very advantageous transfer of the power at each planetary wheel. | ||||||
| 169 | Tilt stabilized / ballast controlled wind turbine | US10271982 | 2002-10-17 | US20040076518A1 | 2004-04-22 | Devon Glen Drake |
| This invention pertains to a horizontal axis wind turbine of down-wind design that tilts rather than teetering to overcome loads produced by gyroscopic precession. Gyroscopic precession occurs to the rotor as it is spinning when it turns to adjust to or follow a wind directional change. It is absolutely necessary to provide a means by which to overcome this phenomena as it can lead to structural failures due to it's extreme effects. Wind turbines that can not overcome these effects usually have an active yaw system that will turn them very slowly in order to not encounter the effects of the extreme loads produced by gyroscopic precession. This invention also provides a means by which to control the rotor speed based upon the using of the turbine's own weight as a basis for that control. These two functions work in unison and are immediate in their response to provide for a superior dynamic wind turbine design that will be more cost effective to produce as well as maintain. It also provides for very stable and reliable operation. | ||||||
| 170 | ATMOSPHERIC COLD MEGAWATTS (ACM) SYSTEM TM FOR GENERATING ENERGY FROM DIFFERENCES IN ATMOSPHERIC PRESSURE | US10231387 | 2002-08-29 | US20040041400A1 | 2004-03-04 | Anthony C. Mamo |
| A system for the generation of energy based upon the differences in the atmospheric pressure at geographically spaced apart sites, referred herein as the nullAtmospheric Cold Megawattnull energy producing system of the invention (hereinafter nullACMnull) comprises at least one long conduit, in the order of many miles long, preferably of at least two portions of different internal areas capable of conducting significant amounts of air there through. In operation the air flow in the conduit will accelerate to a high velocity wind without the consumption of any materials and without the use of any mechanical moving parts. A power converter, such as a wind turbine, in the conduit converts the high wind velocity generated by even minute pressure differences into energy of any desired type such as electricity. The opposite open ends of the conduit are located at geographically spaced sites preferrably selected on the basis of historical information indicating an historical useful difference in barometric pressure. A plurality of conduits each having open ends in different geographically spaced sites may be interconnected to maximize the existing pressure differences that will assure higher and more consistent levels of energy production. | ||||||

| 174 | High tower wind generating system | US542578 | 1990-06-25 | US5062765A | 1991-11-05 | H. Reginald McConachy |
| A more efficient wind power generation system is afforded by extending tower heights to several hundred meters to operate wind catching rotors and generators aligned with the wind direction at various levels along the tower. With multiple vertically cascaded wind generators and higher velocity winds at higher elevations greater power is produced in a system characterized by a small footprint. This is particularly enhanced by a single mast construction, which is supported by a dynamic guy wire tensioning system to accomodate varying lateral forces primarily caused by the change in direction of wind loads on the tower. The mast is built from modular sections connected together at articulated joints, between which the various rotors are stationed. Thus, the accumulated torques and lateral stresses in the tower are minimized and do not accumulate along the length of the tower thereby to lengthen life expectation and reduce the chances for catastrophic failure in the presence of the higher velocity winds encountered. Also maintenance at such heights necessary where movable parts are present, is enhanced by an internal lift in the mast structure and an uppermost work platform with a rotatable lifting crane. | ||||||
| 175 | Coaxial multi-turbine generator | US499170 | 1990-03-26 | US5040948A | 1991-08-20 | Rudy W. Harburg |
| Turbines are suspended coaxially between a hub structure and a pivot. The hub acts to stabilize the coaxial turbine system and it acts as the power take off. The pivot acts to stabilize the other end of the coaxial turbine system. A coaxial assembly of unique flexible turbines convert wind energy into rotational mechanical energy. Driver lines attached to the extremities of the turbines transmit this energy to the extremities of the hub structure. The hub imparts torque to a drive shaft at its center thorough a moment arm and the drive shaft supplies power to a useful application, such as generating electricity. The coaxial turbine system is suspended from tower to tower between existing power transmission lines. Electricity generated by this system is fed directly into the existing power distribution system. This coaxial generator system utilizes a variety of turbine configurations and can be suspended in the wind in a number of ways. | ||||||

| A wind turbine for generation of electricity comprising a large, lightweight wheel attached to a fixed vertical central pylon and oriented to rotate in a vertical plane around a boom having an axis that is substantially horizontal, and pivoted at one end to the pylon. The wind wheel is supported at its rim by a carriage assembly that is constrained to move in a circular horizontal path about the central pylon. The wheel has a cylindrical outer rim and may include one or more perimeter frame structures. The outer surface of the rim is essentially flat in cross section and presents a traction surface for the takeoff of energy from the rim of the wheel. The wheel has a plurality of uniformly spaced radial spindles on which are rolled sails (soft airfoils), which when unfurled catch the wind to provide the rotational motion to the wheel. The carriage assembly may be moved around the pylon by driver means to accommodate for changes in wind direction, or the wind wheel as a whole can be allowed to move freely to assume the preferred wind direction in the manner of a weather vane. The wheel and frame structure are secured to and supports the horizontal boom which lies colinear with the axis of the wheel and projects longitudinally in both directions from the central plane of the wheel. The entire boom structure is supported by means of stays from the perimeter of the rim to the ends of the boom. Detailed rigging and traveler assemblies for control and operation of the wind turbine are disclosed. | ||||||

| The wind powered mechanical and electric power generator, is a process and apparatus which uses the mechanical advantage of a lever arm to multiply the energy of a moving or mobile weight which is wind powered from a propeller drive, and converts by gravity and mechanical advantage said energy to useful work. The unit consists in its simplest form of a counter balanced wheel on one side of a centerline shaft and a concentrated weight on the opposite side, both kept rigid by a connecting structure beam, the entire unit made to revolve around the centerline shaft by moving a mobil weight around the wheel perimeter in concert with the units rotation so as to continually produce an off-balance of weights, which then uses gravity to cause the total unit to rotate. The mobile weight is driven around the wheel by a wind powered small propeller. | ||||||
| 179 | Windmill | US926566 | 1978-07-20 | US4242043A | 1980-12-30 | Peder U. Poulsen |
| The invention relates to a windmill of the type having an elongated propeller shaft inclining upwardly away from the wind direction so that the height of the propeller above ground is substantially determined by the length of the shaft and its angle with the horizontal plane. The invention is based on the recognition that the wind load on the propeller is substantially acting as a longitudinal tensile strain in the shaft when its angle with the horizontal plane is within a certain angle range, and according to the invention it is therefore sufficient to support the shaft by a simple staying device via a bearing. One end of the staying device may be attached solely to the non-rotating part of the bearing, resulting in the achievement of an inexpensive and light construction having a relatively thin shaft. | ||||||
