摘要:
A method and an apparatus are provided for initiating rotation of blades of a wind turbine when wind speed is less than a cut-in speed. A solar powered wind turbine apparatus includes a solar dome with photovoltaic cells, operably connected to a rotor assembly, and an electric motor. The photovoltaic cells convert solar energy from incident sunlight into electrical energy. The electric motor electrically connected to the photovoltaic cells rotates the blades of the rotor assembly using the electrical energy from the photovoltaic cells. The electric motor powered by the photovoltaic cells initiates the rotation of the blades of the rotor assembly when wind speed is less than the cut-in speed, and therefore reduces or eliminates the cut-in speed required to rotate the blades. The blades of the rotor assembly thereafter continue to rotate in response to a force of wind on the blades and/or the powered electric motor.

A hybrid horizontal axis energy apparatus comprising a frame and a rotor assembly rotatably connected to the frame is provided. A drive mechanism is rigidly attached on the rotor assembly and is in engageable communication with an adjacent drive mechanism of an adjacent rotor assembly for rotating the adjacent rotor assembly. One or more solar devices, rigidly attached to the rotor assembly, produce electrical energy. A motor is electrically connected to the solar devices and rotates the rotor assembly about a horizontal axis of the frame on receiving the electrical energy produced by the solar devices. An electrical generator, in engageable communication with the rotor assembly via the drive mechanism, converts mechanical energy produced by the rotation of the rotor assembly to electrical energy. The rotation of the rotor assembly removes light attenuating particles from the solar devices housed on the rotor assembly, thereby increasing efficiency of the solar devices.

A solar powered wheel apparatus comprising one or more photovoltaic cells housed on a rotatable element connected to a rotary object such as a wheel, an electric motor, and an axial shaft, is provided. The electric motor is in electric communication with the photovoltaic cells that power the electric motor and is rigidly connected to the rotatable element that houses the photovoltaic cells. The axial shaft is rotatably connected to the electric motor and rigidly connected to a support structure of the rotary object. The electric motor converts electrical energy produced by the photovoltaic cells into mechanical energy causing the electric motor to rotate about the axial shaft. The rotation of the electric motor rotates the rigidly connected rotatable element that houses the photovoltaic cells. The rotation of the rotatable element housing the photovoltaic cells removes heat from the photovoltaic cells and causes rotation of the connected rotary object.

Low molecular weight serum components (less than 10,000 m.w.), in vaccinated animals and a human subject who has been exposed to a threat agent inadvertently, bound to purified O-polysaccharide (OPS, a polymer of formamido-mannose) and a candidate of a threat agent, such as Brucella suis 145 vaccine is disclosed. These components formed a loose reversible precipitin with OPS in a high-salt borate-buffered agarose gel and bound to the candidate vaccine as observed by capillary electrophoresis. By using modified capillary electrophoresis, the invention also discloses the presence of two larger serum components, one similar in size to that of serum albumin and one resembles that of mannan-binding lectin, that bound to the vaccine. An indirect method for identifying vaccination is the presence of antibodies against Brucella-OPS-antibodies. ELISA, capillary electrophoresis and animal challenge studies showed that as high as 30% of the control animals did not require vaccination. These animals could have been exposed to cross-reactive cross-protective antigens naturally.

An apparatus is provided that comprises photovoltaic cells provided on a first rotatable member, an electric motor having an axial shaft, and a second rotatable member provided with an impeller. The photovoltaic cells capture and convert the solar energy into electrical energy. The electric motor is connected to and is in electric communication with the photovoltaic cells for powering the electric motor. The electric motor converts the electrical energy into mechanical energy for rotating the photovoltaic cells in a first direction about a central axis and for rotating the axial shaft connected to an impeller in a second direction about the central axis. The rotating axial shaft rotates the impeller at high revolutions per minute which generates a flow of air that is directed to the rotating photovoltaic cells on the first rotatable member. The photovoltaic cells are cooled by the air-flow and operate at a lower temperature.
