How Does It Compare With An ERDA-NASA Propeller Turbine?

Según los resultados de este estudio, la máxima amplitud, la fase hiperpolarizante y el potencial de acción fueron significativamente inferiores en el grupo sometido a la magnetoterapia pulsátil. El uso del campo magnético pulsante de una frecuencia de 50 Hz e intensidad de 1 mT tuvo entonces un efecto negativo en el nervio periférico, ya que redujo el valor de la amplitud y la fase hiperpolarizante de su potencial de acción. En otras palabras, la magnetoterapia reduce significativamente los impulsos nerviosos del nervio ciático reduciendo el dolor severo causado por la inflamación del nervio ciático. El potencial de acción del nervio ciático aislado fue el tema de estudio clínico del equipo de Ö. En las neuronas, los potenciales de acción se conocen también como impulsos nerviosos. El potencial de acción es un tiempo corto en el cual el potencial de la membrana celular aumenta rápidamente y disminuye de nuevo para mantener la diferencia de tensión entre el ambiente interior y exterior de la célula durante la propagación de impulsos nerviosos.

LMady: Psoríase e Acupuntura High variation in wind speeds is not the only problem. In FIG. 17, there is schematically shown another system embodiment wherein the rotational energy of wind turbine 310, through its shaft 311, can be converted via gearbox 312 to drive a cable hoist 313. The cable 314 from that hoist 313 attaches through a system of pulleys, generally 315, then to a heavy weight 316 suspended over a high elevation. For example, in the case of a system called ″ Aqua Buoy® ″, a turbine driven by a pump is placed inside the upper part of the buoy in the water, inside the submerged support. 6. In this case, the end of the link 15 ′ of the linear control element 15 or 15b can be connected to the armature 32 at the bottom of the water basin, and the end of the other link 15 ″ of the control element can be connected to the load 33. Thus, the device together with the floating body or buoy 30 repeats the movement of water on the surface, and the control due to the load 33 alternately moves in opposite directions, actuating the gearing of the device and thereby giving unidirectional and continuous rotation to the electric generators.

Thus, in winds of 25 mph, the exposed knife blade-like rotors will be traveling in excess of 100 mph. Gravity-flap Savonius turbines designed with the 40% minimum working surface of the hypothetical example and with the flap mechanism, purport to yield higher efficiencies than the assumed 30%. Thus, in terms of the effective and efficient capture of wind energy, this type of turbine could be highly superior to ERDA-NASA turbines in principle.

Since the design of the parent invention exhibits a very high capacity for extracting wind force, it need not be of such a large size compared to existing ERDA-NASA wind generators. In addition, the device proposed in the invention may have additional applications, even if they have not been described. One of the objectives of the present invention is to provide a device for converting the reciprocating motion of waves into electrical or mechanical energy with the possibility of overcoming known mechanical imperfections and installing not only on land, but mainly directly on water in a floating or semi-submerged or submerged position.

One of the additional objectives of the invention is the creation of a system for generating electrical or mechanical energy using a relatively simple and economical reciprocating or small-volume wave motion and, accordingly, with limited dimensions and minimal environmental impact.

Also, the parent invention will provide a wind turbine readily adaptable to running a water pump instead of an electrical generator. The system proposed in the invention is configured and operates based on the beneficial use of wave motion using at least a floating body or buoy, in particular, to generate electricity directly from renewable resources in combination with a device for generating energy without the formation of CO 2 and (or) other polluting emissions. A principal object of the present invention is to use the power of vertically mounted wind turbines to move heavily weighted devices or objects. The cross-section of long blades has an airfoil shape, and this aerodynamic feature provides the transformation of wind flow energy into rotational energy. Only if one can trap the fluid flow and prevent lateral flow around the vane can one hope to have significant proportions of the fluid energy transferred into a catchment vane.

5 embodiment. Each vane 62 in FIG. A unidirectional drive mechanism (20b) is located between the main shaft (lib) and each driven gear (18b, 19b) connected to it. The unidirectional drive mechanism is a unidirectional bearing or freewheel. In the first case, the device has two main or drive shafts, parallel controlled by the linear control element, each main shaft having at least an output shaft, controlled by the main shaft via a freewheeling mechanism. This main shaft 11b interacts with driven gears 18b, 19b located at each of its ends and attached to a corresponding driven (transmission) shaft 21b, 22b, which is supported by at least one bearing and can be connected to an electric generator, in particular an electric generator Cb.
