Description

POWER GENERATION

FIELD OF THE INVENTION

The invention relates to the field of power generation.

BACKGROUND OF THE INVENTION

Power generation is the foremost step towards delivery of electricity and towards powering human technologies. Electric power has been generated at central stations as early as about 120 years ago. The first power plants were run on water power or coal, and today we rely mainly on coal, nuclear energy, natural gas, hydroelectric, and petroleum with a relatively smaller amount from solar energy, tidal harnesses, wind generators, and geothermal sources. Turbine plants driven by both gas and steam achieve efficiencies up to levels of 60%. Solar panels have known to achieve efficiency levels of up to 30% to 40%. Each power generation system banks on a reservoir of resources. Once the reservoirs deplete and exhaust, the system has to look for a refill of resources or a new location for resources. Analogously, on a smaller scale, a battery is charged up to its capacity, which in turn powers the connected equipment for as long as the charge lasts, after which, the battery has to be recharged. Electrical generators or alternators were invented which convert mechanical energy into electrical energy. As long as there is a continuous input of energy from a resource pool, electrical energy will be provided at the output of the alternator. With the rapid depletion of natural resources, there is a need to conserve energy and reduce the dependency on natural resources as a source for power generation. Considering the technological advance made by mankind, there is a need to provide a consistent and reliable system for power generation which is not dependent on the already depleting natural resources.

OBJECTS OF THE INVENTION

One object of the invention is to generate power.

Another object of this invention is to provide a system that provides a consistent source of power.

Yet another object of this invention is to provide clean energy.

Still another object of this invention is to provide an efficient power generation system.

One more object of this invention is to provide a cost-effective system to generate power.

DESCRIPTION OF EMBODIMENTS OF THE INVENTION

The invention will now be described with reference to the embodiments shown in the accompanying drawings and the embodiments do not limit the scope and ambit of the invention. The description relates purely to the exemplary preferred embodiments of the invention and its suggested application.

FIGURE 1 illustrates a schematic block diagram for generating power in accordance with the present invention and equipment therefor. FIGURES 2 and 3 illustrate various views of a schematic diagram for generating power in accordance with the present invention and equipment therefore.

A system for generating power as envisaged in accordance with the present invention is referenced generally by numeral 100 and is described herein below with reference to FIGURES 1, 2 and 3. There is provided a motor M, typically, a standard motor adapted to convert input electrical energy into output mechanical energy. Motor M is driven by a source of power source PWR. The power source PWR is a standard power source directly connected to the motor M. An alternator A adapted to convert input mechanical energy into output electrical energy is connected to the motor M. The mechanical energy from the motor M drives the alternator A through a belt drive BD (shown in FIGURES 2 and 3). Typically, 2 V-belts of size B- 52 are used. The belts are looped over pulleys Pl and P2 (shown in FIGURES 2 and 3). There is provided a feedback F/B (shown in FIGURE 1) from the alternator A to the motor M by which a portion of the electric power generated from the alternator A is fed back to the motor M, which continues to run on the feedback power. In accordance with the present invention, the output of the motor M provides mechanical energy to drive the input of the alternator A, and the output of the alternator A provides electrical energy to drive the motor M. The mechanical energy from the motor M adds to the resident magnetic potential energy of the alternator A, and gives rise to the additional energy which is available at the output of the alternator A. A major portion of the output from the alternator A is used to supply a load O/P, while a minor portion from the alternator A is fed back to the motor M. The power source PWR in accordance with this invention is extended to include a DC battery and/or a solar power source with solar cell. Once the motor M regulates and starts working at its full load rating, the power source PWR is cut-off. This system will work only when both the motor M and the alternator A are working and driving each other in a steady-state condition. As soon as the motor M or the alternator A stops working, the power generation system 100 will have to be re-started from an external power source PWR. In accordance with an alternate embodiment of this invention, the feedback F/B from the alternator A is extended F/B E to be provided at the input of power source PWR.^' The power source PWR is a battery or a battery bank that is a storage means for various sources of power such as rectified AC mains or solar cells. The power generated at the output of alternator A is mainly fed to a load O/P, and partly fed to the motor M via a battery. The additional power may thus be used for re-charging the battery.
