[0008] TITLE OF THE INVENTION:

[0009] BUOYANCY BASED ROTATIONAL SYSTEM The following specification particularly describes the invention and the manner in which it is to be performed.

[0010] A] TECHNICAL FIELD OF THE INVENTION

[0011]

[0001] The present invention pertains to a rotational turbine system that utilizes the principles of buoyancy and gravitational forces to generate rotational motion. The present invention more particularly pertains to a turbine system with specially designed blades containing a suspended solid wheel and a floater, which facilitate sustained rotational motion and enable electricity generation.

[0012] B] BACKGROUND OF THE INVENTION

[0013]

[0002] The demand for sustainable and efficient energy generation systems has significantly increased in recent years due to growing environmental concerns and the depletion of fossil fuel resources. Traditional energy generation methods, including hydroelectric, wind, and thermal power, rely heavily on external environmental conditions or fuel-based combustion. While these methods are effective, they often suffer from inherent inefficiencies, high operational costs, and environmental constraints.

[0014]

[0003] Hydroelectric power generation, for instance, depends on the availability of flowing water sources such as rivers and dams. Seasonal variations and geographical limitations restrict its feasibility in certain regions. Wind energy, another prominent renewable energy source, is intermittent and requires substantial infrastructure investments, such as large wind farms and storage systems. Fossil fuel-based power generation, while widely used, contributes significantly to environmental pollution and climate change due to greenhouse gas emissions.

[0015]

[0004] Given these limitations, there is a growing need for a self-sustaining and highly efficient energy generation system that minimizes dependency on external environmental factors. The present invention addresses this need by leveraging the principles of buoyancy and gravitational force to achieve sustained rotational motion that can be maintained over a prolonged period of time which can be harnessed for electricity generation.

[0016]

[0005] The concept of buoyancy-based rotational systems has been explored in various forms, but existing designs typically fail to achieve self-sustaining motion without requiring auxiliary energy input. Many previous attempts have incorporated buoyancy-assisted turbines, but they often lack an optimized mechanism to maintain uninterrupted motion. The present invention overcomes these challenges by utilizing a unique combination of weighted and buoyant elements strategically positioned within a rotational turbine system.

[0017]

[0006] One example of relevant prior art is U.S. Patent Application No. US2010117364A1 which describes a buoyancy hydro power installation comprises wave energy collectors and compressors mounted on a platform at sea level which sits on a vertical tower extending below sea level and houses compressed air pipes, expansion pipes, compressed air storage chambers and a turbine at the submerged end of the tower, said installation being tethered to the sea floor.

[0018] C] OBJECTS OF THE INVENTIONS

[0019]

[0007] The primary objective of the present invention is to provide a buoyancy-based rotational turbine system that operates over a prolonged period of time without requiring an external power source.

[0020]

[0008] Another object of the present invention is to design a turbine that generates sustained rotational movement over a prolonged period of time by utilizing the interplay of buoyancy and gravitational forces, reducing reliance on external factors like wind or flowing water.

[0021]

[0009] Yet another objective of the present invention is to develop an energy-efficient turbine system that optimally converts rotational motion into usable electrical energy, thereby improving overall power generation efficiency.

[0022]

[0010] Yet another objective of the present invention is to offer a renewable energy solution that minimizes carbon emissions and dependence on fossil fuels, contributing to environmental conservation.

[0023] [Oil] Yet another objective of the present invention is to create specially designed hollow blades incorporating weighted and buoyant elements that maximize rotational efficiency and fluid interaction. The hollow blade are structures tapering and closed at one end and having hypotenuse open side on the other end of the blade.

[0026]

[0014] Yet another objective of the present invention is to ensure the turbine maintains stable and consistent performance even under variable environmental conditions, thereby increasing its reliability as a power generation system.

[0027] D] SUMMARY OF THE INVENTION

[0028]

[0015] Various embodiments of the present invention provide for a buoyancy-based rotational turbine system designed to generate sustained rotational motion over a prolonged period of time using the principles of buoyancy and gravitational force. The turbine consists of a central rotating shaft and multiple specially designed blades, each containing three distinct sections that interact with a fluid medium to sustain angular velocity over a fixed period of time rotation.

[0016] One of the embodiments of the present invention is a heavy opaque wheel is suspended within a predefined angular range within the blade, exerting a sustained downward force due to gravity. This force aids in initiating and maintaining rotational motion.

[0029]

[0017] Another one of the embodiments of the present invention is a floater, in the form of an airsac, which is positioned within the hollow section of the hyotenuse side of the blade. Upon immersion in liquid, it experiences an upward buoyant force that counters the gravitational pull. This, in conjunction with the unidirectional push generated by the blades of the substructures contributes towards sustained rotational motion of the shaft on which such blade containing substructures rest upon.

[0030]

[0018] Yet another embodiment of the present invention is a section intentionally left hollow to optimize movement and facilitate controlled fluid interaction, ensuring minimal resistance while maximizing efficiency.

[0031]

[0019] Yet another embodiment of the present invention is a hole made on the seam on the face on either sides next to the vertex that is nearest to the shaft, which hole optimizes the ingress and egress of the blade in the fluid, thereby maximizing efficiency.

[0032]

[0020] Yet another embodiment of the present invention is the working principle of the invention is based on a seamless cycle of immersion, weight distribution, and buoyancy:

[0033] • The blade initially moves downward due to the gravitational pull of the weighted wheel, causing it to enter a liquid container with the adjacent side (explained below) of blade facing first.

[0034] • As the blade submerges, fluid seeps into the hollow section from the opening at the base of the blades, increasing weight and promoting further submersion. Thus causes the blade and, as a result, the entire sub-structure to rotate further.

[0035] • As soon as the liquid gets in contact with the floater section, the buoyant force exerted by the floater section gives an upward lift to the blade. Given that the floater section is placed on the hypotenuse side and that the blades are affixed to move unidirectionally, the buoyant force facilitates rotational movement. This is further assisted with the buoyant tube affixed on the rim of the wheel and the optional airsacs that can be attached to both sides of the wheel, thereby giving further force to push the blades unidirectionally and achieve the rotational motion.

[0036] • The above, when replicated by multiple sub-structures affixed to the same shaft, causes the shaft to achieve a stable and consistent angular velocity over a sustained period of time.

[0037] • This rotational energy is harnessed and converted into electrical power through an integrated power generation mechanism.

[0038]

[0021] Yet another embodiment of the present invention is that the turbine's design ensures operation without reliance on external environmental conditions, making it highly efficient and reliable for power generation.

[0022] Yet another embodiment of the present invention is that the system's simplicity minimizes maintenance requirements and enhances durability, making it a sustainable and cost-effective solution for renewable energy applications.

[0043] F] DETAILED DESCRIPTION OF THE INVENTIONS

[0044]

[0024] The present invention comprises a rotational turbine system designed to function using the principles of buoyancy and gravitational force. The core components of the system include a central rotating shaft, a sub-structure consisting a specially designed three blades with internal weighted and buoyant elements, and a liquid container (Tank).

[0045]

[0025] The shaft is a long and narrow rod passes through the centre (hub) of multiple substructures, with such sub-structures being affixed to and, suspended on the shaft. The shaft rests on the pedestal bearings on both sides. The shaft can either be fixed on the centre of the Tank Version (A) or at the rims of the Tank Version (B) described hereunder. The Tank can be either a cylindrical or rectangular container, which can further be fully enclosed (Tank version A) or open from the above and having the height of its sides marginally higher than the height of the

[0046]

[0026] The blade (110, 120, 130) is a meticulously designed 3-dimensional triangle curved on two edges (i.e. having a convex curve and converging at the vertex opposite to the base) while retaining straight lines on all 5 edges. All 6 edges are cojoined by 4 vertices, with the 3 edges meeting at the vertex opposite to the base hereinafter referred to as the "Apex Vertex").

[0047]

[0027] The base forms a triangular (A) form, with three base edges a single edge and two curved edges converging at the point of intersection.

[0048]

[0028] The adjacent side contains vertices A, B, the opposite sides contain vertices B C and D and, the hypotenuse sides contain the vertices A, C and D. The vertex B is angled 110 degrees. The blade converges into a single seam (replicating the seam of a blade) on the adjacent and widens as its approach the curved hypotenuse. The blade is enclosed hollow from within but enclosed on all sides except from the base, providing an opening to the hollow space (also referred to in this document as "Vacant Section") within the blade. The blades are affixed to the hub of the sub-structure through a strip that extends beyond vertex C thereof. A hole is placed on the seam next to the vertex C on the face on either sides.

[0049]

[0029] Each blade is affixed at an angle of 120 degrees from each other.

[0050]

[0030] Each blade is further divided into three key sections: i. Weighted Wheel (150-200): An opaque, wheel of a specified weight (150). The rim of the wheel is covered with a tube that can house air / gas or a combination thereof. The sides (either side or both sides) of the wheel can, optionally be, affixed with an arrangement of cylinder / tubes / gas bag / inflatable bag / bladder / balloon, any other structure capable of housing air / gas or mixture housed in cylinders / tubes / gas bag / inflatable bag / bladder / balloon (collectively referred to as "Airsacs") shaped in the form of a hollow circle, circular hollow section, cylindrical shell, or small pockets of pillow shape, rectangular, square, all types of polygonal shapes (whether opaque or hollow from the centre)is suspended within the hollow space of the blade using a rope (160) which is anchored at a point which is equidistant from vertices A and B on the adjacent side .

[0051] Due to gravity, this wheel exerts a downward force, aiding in rotation by ensuring the blade maintains a steady downward pull. ii. Floater Section (210-230): Another Airsac (210) is positioned on the hypotenuse face within the hollow space of the blade and be placed at a point within the triangle created between vertices A, C and D. Upon such Airsac's immersion in liquid, it generates buoyant force, lifting the blade and sustaining rotational motion. The floater's design is optimized to ensure maximum buoyancy, thereby counteracting gravitational force efficiently. iii. Vacant Section (240-270): This section remains hollow, allowing optimized movement and controlled interaction with fluid to enhance efficiency. It reduces unnecessary drag and ensures the blade moves smoothly through the liquid, facilitating seamless rotation.

[0052]

[0031] The shaft hosts multiple numbers of such sub-structures in an arrangement such that the blades of all such sub-structures face in the same direction and no blades of the substructures are aligned with the blades of other sub-structures, but that all the blades maintain a uniform difference ranging between 5 degrees to 20 degrees.

[0053] The cumulative movement of the all the sub-structures in the same direction generates the necessary torque to achieve

[0054]

[0032] The turbine system converts rotational motion into electrical energy on a sustained basis, thereby presenting an efficient, self-sustaining alternative to conventional energy systems. The unique interplay of gravitational and buoyant forces ensures a stable, environmentally friendly, and cost-effective approach to power generation.
