ELECTRICAL POWER GENERATION SYSTEM USING RENEWABLE ENERGY

摘要

The electrical power generation system using renewable energy is particularly adapted to provide electrical power to an independent or remotely situated electrical device such as a street light, emergency call box, or illuminated road sign. The system includes a pivotally mounted venturi with vanes assuring that the venturi is oriented into the prevailing wind. A vertical axis wind turbine is installed in the venturi throat, and drives a shaft extending through the column upon which the venturi is installed to a generator at the base of the column. The venturi and vanes may include photovoltaic cells thereon for further electrical power. The venturi may be heated from a geothermal source, and may include a variable diameter internal wall to adjust the cross-sectional area of the throat of the venturi. The use of functionally graded materials and other phase change materials may also improve the performance of the device.

主权项

1. An electrical power generation system using renewable energy, comprising:
a venturi having an inlet and a throat, the throat having a smaller diameter than a diameter of the inlet; a wind turbine disposed within the throat of the venturi to generate electrical power by rotation of the wind turbine by air flowing through the throat of the venturi; and geothermal heating means communicating with the venturi to heat the air flowing through the venturi to increase the velocity of the air flowing through the throat of the venturi to increase the rotational speed of the wind turbine to increase the electrical power generated by rotation of the wind turbine.
