The present invention relates to generators and more particularly to a thermal generator to generate electrical power from heat. In addition, generators can be driven by wind from the turbines or a spinning vent. The generators can also be driven by an electric motor that is powered from a solar panel.
Over the last several years, the price of electricity for both homes and businesses has risen steadily. Most electricity is generated as result of the burning of fossil fuels in order to power turbines which in turn are used to generate electricity. The electric generating stations are typically not located near metropolitan areas. Consequently this electricity may be required to be transmitted over long distances in order to reach the consumers of the electricity. Many people are recognizing the hazards to the environment as a result of the pollution resulting from the burning of the fossil fuels.
Consequently, it would be desirable to find a way of generating electricity that would eliminate the need to burn fossil fuels. It would be advantageous if the cost of generating electricity could be reduced and if the generation of electricity was generated from renewable resources in order to eliminate the depletion of the resources of the planet. Some people have advocated the use of wind power in order to reduce the price of electricity. The solution is advantageous; however, the solution may require a high tower in order to reach a position where the wind blows freely. Furthermore, not all the localities have sufficient wind in order to power a turbine. One of the biggest needs for electricity especially during summer time is the need to generate electricity for air conditioning. Logically, the need for air conditioning is greatest when and where the temperature is relatively high. In southern climates, this need is especially significant during the summer months.
Generally during the summer months, a significant amount of heat is generated and stored within the attic space of most homes and businesses. Insulation may be provided in order to keep the heat in the attic space from entering the living space of homes or businesses. Homeowners and businesses may employ electric fans or wind driven (turbines) fans in order to remove this heat from the attic. It would be desirable to have the capability of transforming this heat in the attic space into usable electricity.
A device to generate electricity for building may include a rotating heat electric generating device including turbine blades to rotate in response to heat escaping an attic of the building, a DC/AC power inverter to convert the energy generated by the rotating turbine blades into electricity energy, a storage battery device to store the electrical energy, a switch device to receive the electrical energy from the storage battery device and to switch between a electric bus of the building or a utility service provider, and a controller to control the storage battery device and the switch device so the storage battery device selectively charges and discharges the electric power and so the switch device switches between the building and the utility service provider.
The DC/AC power inverter may convert the DC power from the storage battery device to AC power for the splitter switch device, and the apparatus may include a solar electric generating device to generate electric power from the sun's rays.
The solar generating electric device may be connected to an electric motor, and the solar generating electric device may be connected to the storage battery device.
The invention may be understood by reference to the following description taken in conjunction with the accompanying drawings, in which, like reference numerals identify like elements, and in which:
The present invention includes a system 100 and an apparatus for generating electricity based upon the heat which is typically generated within the attic space of a home or business. The heat may drive precision rotating vents which drive precision generators to produce DC or AC power by employing a DC battery storage/inverter (to change DC power to usable AC power) or employing an AC generator that may generate electricity that can be used directly into the electrical bus of the building, voltage regulator and controller switches. The building may be a home or a business or any building with an attic. The generation of electricity in this manner may save the consumers and businessmen large amounts of money that would otherwise be paid to the local utility. Furthermore, since the electricity is locally generated, there is no need for long transmission lines and the associated costs of building and maintaining a transmission system. The present invention does not rely solely on wind power and may reduce global warming. These types of systems would provide additional security and comfort to our nation and provide electricity at a significantly lower cost. It is generally known that heat rises and cool air falls. Consequently, the present invention advantageously takes advantage of this phenomenon in order to generate electricity. The present invention employs a rotary heat vent which may include fins or blades which rotate about a central shaft.
Alternatively, the system 100 may include a solar electric generating device 101 which may generate electricity and which may be connected to an electric motor 105 by a wire. The electric motor may rotate the first driveshaft 107 to generate electricity which may be stored in the storage battery device 113 as described herein above. Alternatively, the solar electric generating device 100 may generate electricity and transmit that electricity to the storage battery device 113 by a wire which may store the electricity as described above. A turbine that is driven by the wind, for example by a spinning vent, can also generate electricity for the present invention. The spinning vent may be positioned close to the crest of the roof.
While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and are herein described in detail. It should be understood, however, that the description herein of specific embodiments is not intended to limit the invention to the particular forms disclosed.
