ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an energy generating system, and more particularly, a system suitable for use in, or external of, a house, building, factory or other structure for generating electrical, mechanical and other energy by convection utilization.
Power generation by solar energy using conventional technology is inefficient, providing an efficiency, for example, of about only 15% In addition, the cost associated with solar energy generation is generally high.
In living areas, and in and about various other enclosed structures, convection is a naturally occurring phenomenon caused by temperature differences at upper and lower indoor positions. Its usefulness however in converting the energy of the air stream associated with such convention has heretofore been neglected, despite the ability to efficiently harness its energy.
Accordingly, it is an object of the invention to provide a convection energy generating system which overcomes the drawbacks of the prior art.
It is a further object of the invention to provide a convection energy generating system which efficiently and economically converts convectional flow into useful energy.
It is yet a further object of the invention to utilize convection of fluid by connecting both portions high and low in temperature to each other, or operating on the chimney effect and high temperature obtainable from solar heat, air-conditioning heat, cooking heat, body heat, general living heat, etc., and produce useful electrical and/or mechanical energy, ventilation energy and other energies therefrom.
SUMMARY OF THE INVENTION
Briefly stated, the present invention provides an energy generation system which utilizes convection flow of a fluid media caused by differences in temperature to generate useful energy therefrom. A conduit for directing convection circulation is provided for permitting conversion of forces associated with the movement of the fluid media in the conduit into a usable energy by its effect on a generation device as the fluid media flows past such device.
In accordance with various embodiments directed to use in generating electrical energy in a home environment or other building structure, the energy generation system comprises a conduit into which is vented heated air from the interior of the structure. The conduit is open to the outside at a top thereof, such that by virtue of the chimney effect, an upwardly rising stream of air within the conduit is produced by convection. A fan-operated generator placed in contact with the stream of air produces usable electricity.
In alternative embodiments also directed to electrical generation for various building structures, the conduit referred to above for channeling a stream of convected air is placed external of the building and is heated by solar rays which create the flow of air within the conduit.
In further embodiments, directed to use in connection with building structures as well as hand-held applications, such as for example in cameras and cellular phones, instead of employing air, a magnetic fluid is used to conduct convention forces. Energy is generated by a coil wound about a continuous enclosed conduit in which the fluid is made to circulate, and which generates electricity by Fleming's right hand rule.
The above, and other objects, features and advantages of the present invention will become apparent from the following description read in conjunction with the accompanying drawings, in which like reference numerals designate the same elements.
