| 20090263232 | COMPACT AIR COOLING SYSTEM - An apparatus for air cooling an object. The apparatus includes a plate including a first surface and a second surface and a plurality of aerodynamic fins being fixedly disposed on the first surface in an arrangement along periphery of the plate. The arrangement of the plurality of aerodynamic fins defining a central volume of space. Additionally, the apparatus includes a blower including a plurality of impeller blades rotatably disposed within the central volume of space for rotary motion about an axis of rotation. In particular, the second surface is for thermally contacting with the object and the axis of rotation is substantially perpendicular to the first surface. Furthermore, the rotary motion of the blower creates an air inflow along the axis of rotation into the central volume of space and an air outflow through the plurality of aerodynamic fins in radial directions. | 10-22-2009 |
| 20110280708 | VERTICAL AXIS WIND TURBINS - A vertical axis wind turbine comprising a shaft rotatable about a longitudinal axis and a plurality of substantially rigid blades mechanically coupled to the shaft, each of the plurality of blades comprising an elongate body having an upper and a lower end, wherein the upper end and the lower end of each blade are rotationally off-set from each other about the longitudinal axis such that each blade has a helix like form, the section of the elongate body of each blade, taken perpendicularly to the longitudinal axis, being shaped as an aerofoil having a leading edge and a trailing edge and a camber line defined between the leading edge and the trailing edge, characterized in that the aerofoil is arcuately shaped such that the camber line lies along a line of constant curvature having a finite radius of curvature. | 11-17-2011 |
| 20120189428 | WIND TURBINE - A wind turbine device comprising a base frame which supports a vertical axis wind operated rotor, the axis being associated to a user device and being contained in a matchingly-dimensioned cylindrical casing exhibiting two openings, respectively an inlet and an outlet, aligned perpendicular to the rotor axis, the casing being driven to rotate about the axis by a member sensitive to the direction of the wind, such that the inlet opening is always facing into the wind. | 07-26-2012 |
| 20130294886 | PRIME MOVER - A prime mover that is powered by the energy of a fluid is provided. Such a prime mover may include a first fairing, a second fairing spaced apart from the first fairing to define a gap therebetween and a blade assembly mounted on a shaft that extends between the first and second fairings. The first and second fairings each have a curved peripheral edge for directing a fluid into the gap. When the fluid flows into the gap it contacts the blade assembly to thereby rotate the blade assembly about an axis that is defined by the shaft. The prime mover may be mounted on a cell phone tower and used to generate electricity for powering components of the tower and/or for providing electricity to the power grid. | 11-07-2013 |
| 20130315703 | WIND TURBINE WITH VERTICAL AXIS - A turbine, for example a wind turbine, is equipped with a rotor ( | 11-28-2013 |
| 20140334912 | ACTIVE WINDMILL WITH THE AXIS OF ROTATION TRANSVERSE TO THE DIRECTION OF THE WIND - The active windmill with the rotation axis transverse to the wind direction with at least one windmill module containing an assembly of counter-rotating impellers operating in the tandem setting and provided with a two-part guiding plate that covers the impeller parts moving against the wind, wherein each of the guiding plates is located between the mast and one of the impellers, characterized in that the guiding plate's right and left parts are separate elements and are connected with each other by tensioning assembly. | 11-13-2014 |
| 20150104293 | V-SHAPED ARRANGEMENTS OF TURBINES - A V-shaped arrangement of turbines adapted to orient in such a manner that crosswind enters the arrangement in a direction that is substantially parallel to the axis bisecting the arrangement is described. The V-shaped arrangement includes clockwise rotating turbines and counterclockwise rotating turbines. | 04-16-2015 |
| 20150139778 | Wind Turbine Power Enhancement, Utilizing Convergent Nozzle and Embedded Blades - Systems are provided for increasing the power to be extracted from a wind stream by a wind turbine, including placing a duct and nozzle system, or cluster of such systems, up-stream of the wind turbine. In certain embodiments, the nozzles are convergent and the blades of the wind turbine are embedded in a narrower cylinder thereof. | 05-21-2015 |
