Another object is to provide a Rotating Flexible Wing Power System that mounts between moveable supports such that the wing can be made to face into the wind to extract an optimum amount of energy. Another object is to provide a Rotating Flexible Wing Power System that mounts between natural or man-made structures so that energy is extracted from the cross sectional areas of flowing air, water, or other fluids between these structures.
Another object is to provide a Rotating Flexible Wing Power System that can be mounted on top of tall buildings either in vertical, angled or horizontal configurations. Another object is to provide a Rotating Flexible Wing Power System made of an array of rotating wings suspended either in vertical, angled or horizontal configurations between any combination of the following: flat ground, hills, mountains, and man-made objects like bridges, towers, and buildings. Another object is to provide a Rotating Flexible Wing Power System that utilizes a long flexible rotating wing to attain relatively high altitudes at the top of its trajectory extracting the larger amount of energy that exists at higher altitudes. The present invention discloses such a system. Although the device generates high torque, the high stresses in the device require a large structural mass to unit area ratio.
The changes to the radius length correspond to a continuous change in the distance between the ends of the wing, with the distance between the ends shorter on the downwind side and longer on the upwind side, resulting in the wing creating longitudinal oscillations of its ends having a relatively large amount of force. Attention is called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specific construction illustrated and described within the scope of this application. Other objects and advantages of the present invention will become obvious to the reader and it is intended that these objects and advantages are within the scope of the present invention. Given that most fluids flow in a substantially horizontal manner, whether air currents or water currents, orienting the axis of rotation of the turbine vertically allowed the Darrieus device to capture energy of moving fluids irrespective of variances of the direction of fluid flow.

The present invention relates generally to aero-power and hydropower and more specifically it relates to a Rotating Flexible Wing Power system for extracting low-cost electricity and mechanical energy from moving fluids including wind and water currents. Traditional windmills are the most common examples of devices used to capture energy from moving fluids, namely wind. These disadvantages make these designs more difficult and expensive to operate than traditional wind systems. Where windmills are combined with generators to produce electricity, the generators are typically located on the support structure, making access to the system and generator difficult.
Such system should be simple to erect, operate, and maintain, accommodate fluid flows from any direction, and be efficient in both the power stroke and the return stroke for maximum net energy capture. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of the description and should not be regarded as limiting. Figure 7 is a schematic top view of the present invention depicting where the radial forces should act on the wing in a preferred embodiment. In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of the construction or to the arrangements of the components set forth in the following descriptions, illustrations or drawings. This and its utilization of inefficient wind drag forces rather than lift forces make it less efficient and less viable than traditional windmills.

Moreover, traditional windmills are typically massive structures requiring considerable capital costs for construction, operation, and maintenance. Pomadas para dolor de espalda . 1, 1926), sought to overcome many of the deficiencies of traditional windmill design by providing for a turbine having fixed rigid blades disposed about a vertically oriented axis. The multiple blades of the windmill rotate about a horizontal axis oriented preferably in parallel with the air flow. Means are employed to manipulate the orientation of the airfoils relative to the air flow to better allow withdrawal against the air flow, but substantial energy is nevertheless wasted during airfoil retraction. Once the tethers have reached maximum extension they need to be retracted, which results in the airfoils being drawn against the air flow with a resulting loss of efficiency. These devices have the advantage of being easily oriented to the direction of wind flow for maximum energy capture during energy capture, as well as being able to reach higher elevations where the wind is stronger without the need for expensive load-bearing towers, but they have the disadvantage of requiring complicated systems for controlling and resetting the airfoils and are susceptible to complete operational shutdown when the wind velocity decreases below a minimum level.
