Abstract: When planning and setting up wind power installations, the visual detractions to be expected on the part of the wind power installation on the environment play an increasingly important part in approval and acceptance. The shadow casting caused by the wind power installation on the adjoining properties is often perceived by the residents as being very troublesome. A wind power installation is provided by means of which shadow casting regulation is improved. That is achieved by a method of operating a wind power installation wherein a first light intensity is detected in a region of direct light irradiation and a second light intensity is detected in a shadowed region, and wherein the wind power installation is shut down if the difference between the first light intensity and the second light intensity is greater than a predetermined value.

Abstract: An air turbine power propulsion engine for use in powering a vehicle, i.e. automobile or plane, or an electrical generator. The engine is housed in a generally circular housing that features a tapered air intake end and a downstream exhaust end. Within the housing is a generator, first and second drive shafts, and at least one compressor. The at least one compressor is driven by the first drive shaft, while a series of turbine blades drive the second drive shaft which in turn drives the generator. The invention incorporates into the engine a differential gear mechanism to accelerate and compress the air that enters the engine, where the gear mechanism drives the compressor at a higher speed than the turbine blades. A second such mechanism, alone or in combination with the gear mechanism, lies in the use of an air recirculation duct works.

An LED tail light is connected to an over-voltage protecting circuit of a CDI unit. Electric power is supplied from a power supply control section to the CDI unit and is also supplied to the LED tail light through the over-voltage protecting circuit. Thereby, the over-voltage protecting circuit of the CDI unit protects the LED tail light from an over-voltage condition.

Abstract: A large pressure differential is created between the leading face of the rotor blade and the trailing face of the rotor blade during the power cycle which creates a large amount of force that rotates the rotor blade about the central shaft. In some embodiments, gaps are provided between the inside edge of the rotor blade and a stationary shaft which vents wind collected by the rotor blade during certain portions of the rotation cycle. The vented wind increases the pressure on the trailing face of the rotor blades during the return cycle to further assist in the efficiency of this system. In addition, an integrated power plant is disclosed that provides a source of renewable energy in the form of a cross-flow wind turbine that includes solar cells mounted on south facing surfaces of the stators. The stators can be used to store liquids and fuels generated by the renewable energy sources.
