DETAILED DESCRIPTION OF THE INVENTION
While the specification concludes with claims defining the features of the invention that are regarded as novel, it is believed that the invention will be better understood from a consideration of the following description in conjunction with the drawing figures, in which like reference numerals are carried forward. It is to be understood that the disclosed embodiments are merely exemplary of the invention, which can be embodied in various forms.
The present invention provides a novel and efficient power generation system that converts mechanical energy into electricity using a plurality of spherical balls and a conveyor assembly having conveyor-drive system which transports the balls. The conveyor-drive system rotates is coupled to a generator operably configured to produce electricity. Embodiments of the invention also provide a lift assembly with a lift-drive system operably configured to move the balls along a ball-platform translation path in order to provide a continuous movement of the balls from the lift-drive system to the conveyor-drive system.
Referring now to FIG. 1, one embodiment of the present invention is shown in a perspective view. FIG. 1 shows several advantageous features of the present invention, but, as will be described below, the invention can be provided in several shapes, sizes, combinations of features and components, and varying numbers and functions of the components. The first example of a power generation system 100, as shown in FIG. 1, includes a partially enclosed container assembly 102 housing a plurality of spherical balls 104. The term “partially enclosed” includes the container assembly 102 defining at least one aperture that allows the balls 104 to be dispersed from the container assembly 102 through the aperture.
With brief reference to FIGS. 1-2, the balls 104 may be made of, without limitation, a steel material, a metal material, or another durable material suitable for use with the power generation system 100. In one embodiment, the balls 104 each include a weight of approximately 250-350 pounds. In other embodiments, the weight of each of the balls 104 may be outside of this range. The balls 104 are not limited to being a spherical shape; rather, may be oval, or another alternative shape. FIGS. 4 and 5 depict a bottom elevational view and a top plan view of the balls 104, respectively.
With reference again to FIG. 1, advantageously, the weight of the balls 104 is configured to assist in moving a conveyor assembly 106 having a conveyor-drive system 108 including a plurality of ball-catch members 110, as will be explained further herein. Generally speaking, the conveyor-drive system 108 may be, without limitation, a belt conveyor, a chain conveyor, a roller conveyor, or another type of conveyer.
FIG. 1 depicts the container assembly 102 at a container height 112 disposed above the ground surface 114. In one embodiment, the container height 112 is at least 12-14 feet above the ground surface 114. In such configuration, in one exemplary embodiment, when each ball 104 weighs approximately 250 pounds and the container height 112 is approximately 12 feet from the ground surface 114, the power generation system 100 may generate potential energy of approximately 3000 ft-lb of energy or 40,674 Joules. In other embodiments, the container height 112 may be outside of this range. In one embodiment, the conveyor assembly 106 includes a proximal end 116 coupled to the container assembly 102 and a distal end 118 separated from the proximal end 116 by a conveyer length 120, which may vary according to the size of the physical location of the power generation system 100.
FIG. 1 depicts the conveyor assembly 106 spanning downwardly from the container assembly 102 at a location below the container height 112. In one non-limiting embodiment, the conveyer assembly 106 spans downwardly from the container assembly 102 at approximately a ninety degree angle with respect to a ground surface 114. In one embodiment, as best shown in FIG. 3, the balls 104 move from a railing 300 coupled to the container assembly 102 to the conveyor assembly 106. Advantageously, the railing 300 is angled in a downward direction such that the balls 104 roll from the railing 300 to the conveyor assembly 106 due to gravity and without the use of any mechanical or electrical switches and/or devices which would add to the complexity and cost of the power generation system 100.
With reference again to FIG. 1, as a further advantage, the downward angle of the conveyor assembly 106 is operably configured, via the ball-catch members 110, to transport the balls 104 to along the conveyor assembly 106. In one embodiment, a generator 124 is operably coupled to the conveyor-drive system 108. Advantageously, movement of the conveyor-drive system 108 spins the generator 124, resulting in an electrical output. Said another way, the generator 124 is operably configured to produce electricity.
FIG. 1 depicts the power generation system 100 having a lift assembly 126 including a lift-drive system 128 spanning from a ball-receiving position 130 to a ball-dispersing position 132. The lift-drive system includes a ball-platform 134 configured to assist in transporting the balls 104. The lift assembly 126 includes a height 136 disposed above the ground surface 114 that is greater than the container height 112. In one embodiment, the height 136 is at least approximately 15-20 feet above the ground surface 114. In other embodiments, the height 136 may be outside of this range. The height 136 being disposed above the container height 112 allows the balls 104 to flow due to gravity from the ball-dispersing position 132 back to the container assembly 102. In such configuration, the balls 104 may flow in a continuous manner from the lift assembly 126 along the conveyer assembly 106 to the container assembly 102.
Generally speaking, the lift assembly 126 may be operably configured to operate as a pulley system. For example, with brief references to FIGS. 1 and 6, in one embodiment, the lift assembly 126 includes a platform 138 operably coupled to the ball-platform 134, through for example, and without limitation, a cable 140 and a pulley 142. The platform 138 is sized to hold a plurality of users 144. The term “users” is defined herein in its broadest possible sense and includes people, robots, or another object capable of movement. In one embodiment, the platform 138 includes a raised position and a lowered position along a lift translation path. The raised position includes the height 136 disposed above the ground surface 114 that is greater than the container height 112, as mentioned above. In one embodiment, movement of the platform 138 along the lift translation path is operably configured to move the ball-platform 134 along a ball-platform translation path to transport the balls 104 to the ball-dispersing position 132. More specifically, in one exemplary embodiment, one a designated number of users 144 enter the platform 138, the platform 138 is operably configured to move from the raised position to the lowered position, causing the ball-platform 134 to move along the ball-platform translation path from a lowered position to a raised position, i.e., the pulley system reverses the direction of the applied force. Naturally, a weight of the users and the weight of the balls 104 produces a ratio of 1:1, i.e., the weight of the users and the weight of the balls 104 is equal.
The ball-platform translation path extends substantially from the ball-receiving position 130 to the ball-dispersing position 132 of the lift-drive system 126. From the ball-dispersing position 132, the balls 104 may travel to the container assembly 102. Thereafter, the balls 104 travel along a descending directional path which extends the conveyor length 120 from the container assembly 102 back to the ball-receiving position 130. In one embodiment, the plurality of ball-catch members 110 extend outwardly from the conveyor assembly 106 and are disposed in an orthogonal relationship with respect to the descending directional path. Accordingly, such configuration assists in maintaining the balls 104 on the conveyor assembly 106 and in a spacial relationship with respect to one another as the balls 104 travel along the conveyer length 120.
With reference to FIG. 1, in one embodiment, the power generation system 100 includes a secondary electricity generation grid having a plurality of individual user-activated energy generation devices 146. In one embodiment, the plurality of individual user-activated energy generation devices 146 are operably configured to raise and lower the platform 138 of the lift assembly 126. In other embodiments, the plurality of individual user-activated energy generation devices 146 may be coupled to one or more batteries (not shown). In one embodiment, the user-activated energy generation devices 146 are pedal-powered generators, e.g., bicycles. In other embodiments, the user-activated energy generation devices 146 may be another type of exercise equipment. Advantageously, in one exemplary, non-limiting embodiment, each user-activated energy generation device 146 may be operably configured to produce at least 100-200 watt-hours of electricity during a one-hour period.
