FIELD OF INVENTION
The present invention relates to a novel way of hamesslng and renewing fluid energy to generate power and/ or electricity
BACKGROUND OF THE INVENTION
There have been various attempts to genersite power of electricity. These attempts can be broadiy categorized as the use of depletable resources, and the use of renewable energy.
Current diepletable resources include coal, oil and nuclear energy. These resources are known to be pollutive not only upon extraction, and also when these resources are being used. Further, these resources are not freely available in ail parts of the world, and regions who possess these resources, may tend to hold the rest of the world 'at ranscm'. More importantly, the negative side effects of the use of nuclear energy may even be long term.
Notwithstanding the negative Impacts of thase depletable rasources, they are currently still being mined, as they are the traditional energy resources. Thus, these resources are being threatened.
The iong-term solution Is to engage end harness known renewable energies, for example, solar energy, wind energy and hydraulic energy.
Most known attempts which operate using renewable energies work on very tight parameters as they rely solely on the presence of these renewable energies, and the fact that these energies are seasonal and uripredictable. These are not always found where they are needed. For example, when hydraullcs are used as a power generating source, the power generation machlnes will need to be physlcally built at or around moving water, for example, rivers or near dams. This may not always be economlcatly feaslble, and may require rather long term payback.
In another example, renewable energy like solar energy is limited during wiiitry periods, when power or electricity generation is needed mors.
A solution to this is an arrangement to channel excess energies to batteries for use during off load periods. However, these batteries not only are expensive, but also have a relatively short life span and are toxic. Most impcrtantly, due to the relatively short life span, the continued disposal of these toxic substances are pollutive to the environment.
There is thus a need to alleviate and ameliorate all of these problems as highlighted

DETAIUD DESCRIPTION OF THE INVENTION
Reference will now be made in detail to the preferred embodiments of the invention, examples of which are lllustrafed in the accompanying drawings. While the invention will be described in conjunction with the preferred enntodiments, it will tie understood that they are not intended to limit the invention to these embodiments. On the contrary, the invention is intended to cover alternatives, modiflcations and equivalents, which may be Included within the spirit and scope of the invention as defined by the appended claims. Furthermore, in the folowing detailed description of the present invention, numerous specific details are set forth in order to provide a thorough understanding of the present
invention. However, it will be obvious to one of ordinary skill of the art that the present invention may be practiced without these specific details. In other Instances, well known methods, procedures, components, and features have been described In detail so as not to unnecessarity obscure aspects of the present indention.
The portable hydro-generator 100 in a preferred embodiment is as depicted in Figure 1 of the drawings. The portable hydro-generator 100. Includes a tower 10, which is filled with a driving fluid 110. The driving fluid 110 is introduced Into a semi-sealed tubular housing 80 through the inlet means 60, which, in a preferred embodiment, is a series of conduits 61. The semi-sealed tubular housing 80 is defined as having a drive portion B1, a return portion 82 and an output chamber 83. The semi-seated tubular housing 80 is previously primed with a fluid 70. When the driving flud 110 from the tower 10 flows through the series of conduits 61 via potential energy, this potential energy transforms to kinetic energy, thus allowing the driving fluid 110 implnges on the fluid 70 at the drive portion 81 of the semi-sealed tubular housing 80, The region of the drive portion 81 where the driving fluid 110 impinges on the primed fiuid 70 within the semi-sealed tubular housing 80 is known as the pressure chamber 21. It is the pressure chamber 21 that the main Input energy is received for the portable hydro-genarator 100. It 5s to be appnsciated that whilst it is preferred that the level of the driving flald 110 in the tower 10 is as high as possible to create a higher pressure head, ii is understood that the difference in height between the level of the driving fluid 110, and the height of the output chamber 83, will determine the amount of backflow occurring, The level of driving fluid 110 Vflthin the tower 10 (s preferably slightly higher than the output c;hambef 83, to minimize a backflow occurring within the semi-sealed tubular housing 80 of the portable hydro-generator 100, and also to create a high pressure head to allow a greater impinging force on the fluid 70.
It is to be understood that the driving fluid 110, and the fluid 70, are the sams fluid, and have been defined as such for the purposes of explaining the present irrvention In greater detail. Further, as the present invention is intended to be for use In domestic and Industrial applications, this fluid Is preferably a fluid commonly used and found, and Is preferred to be water,
A series of paddles 30 is linked within the periphery of the tubular housing 80, and is the main conveyance of the Impinging force introduced to the portable hydro-generator 100. via the pressure chamber 21. The paddies 30 are linked by means of a finkage assembly, which, in a preferred embodiment, and as shown ir Figure 1, Is e linkage bar 34. It Is to
be appreciated that the paddles 30 are in a stretched position 36 when in the drive portion 80, and In a closed position 37 when in the returm portion 82.
As the driving fluid 110 is introduced into the prassure chamber 21. the potential energy possessed by this fluid 110 by virtue of the height of the tower 10 above the pressure chamber 21 is transformed to kinetic energy, and the driving fluid 110 is allowed to impinge on the primed fluid 70 of the semi-sealed tubular housing 80. This initial force causes the paddles 30 within the pressure chamber 21 to move downwards, and to turn towards the return portion 82. As the tubular housing 80 is previously primed, the fluid 70 within the drive chamber will also move downivards. Further, as the paddles 30 are linked through a Inkage assembly, the subsequent paddles wilt also begin to move m an anticlockwise direction, as shown In Figure 1. to ensure that the maximum kinetic energy from the driving fluid 110 Is harnessed, the paddles 30 are maintained in a stretched position 36 throughout the drive portion 81 by means of a stop means 38 on the paddle 30. This stop means 38 will prevent the paddles 30 from rotating to a closed position 37. Further, to minimize resistive forces, the paddles 30 have to be in a closed position 37 at the return portion 82. This is done by Including a wedge 13 at a drop oft point 23. This wedge 13 tilts the paddle 30, so that it wilt be rotated to a closed position 37. Subsequent paddles 30 that pass through the wedge 13 will also rotate to a closed position 37. This wedge 13, in a preferred embodiment, is a protrusion from the inner wall of the semi-sealed tubular housing 80. It is envisioned that the wedge 13, can be in the form of a plurality of wedges 13, and It can be provided on the guide walls 14 of the semi-sealed tubular housing 80. It is further to be understood that the wedge 13 may be at a position after the drop off point 23, and not directly at the drop off point 23.
It is at the drop off point 23, where the tubular housing 80 is exposed to environmental pressures. To maintain the tubular housing 80 n a primed condition, the portable hydro-generator 100 is further fitted with a lower receptacle tank 40. The height of the lower receptacle tank 40 is such that It Is lower than the height of the drop off point i',3, so as to maintain a region of atmospheric pressure on the drive portion 81, thus creeting a larger imbalance, or greater driving force on the drive portion, and comparefivsly less resistive force on the return portion 82. The lower receptacle tank 40 is further ftted with an overflow tank 41 with a return pump 42 so that the level of driving fluid 110 in the tower 10 can be maintained. The level of fluid 70 within the lower recepiacie is known as the pencelved fluid level, and it is appreciated that the percelved fiuid level maintains et the level height of the overflow tank 41,
It is to be appreciated that the internal diameter of the tubular housing 80 is of a larger diameter at the drive portion 81 than at the return portion 82. This te to further allow an imbalance within the tabular housing 80, such that the downward force nt the drive portion 81 Is greater than the upward reslstive foreĀ© of the return portion 82. and hence, create a net anti-clockwise rotation of the primed fluid 70, and also the paddies 30.
Once the paddles 30 rotate to a closed position 37 after passing through the wedge 13, the paddles 30 are moved to the return portion 62. To maintain the paddles 30 at a closed position 37, the tubular housing 80 has guide walls 14, which maintain a minimum internal diameter with the wall of the tubular housing 80 to maintain the closed position 37 of the paddles 30, At this dosed position 37 at the return portion 82. the upward resistance is minimized. The output chamber 63 is preferably situated at the top of the tubular housing 60 as seen in Rgure 1. The output chamber 83 houses the sprocket wheel 50. The output chamber 83 further includes an abutment 12, to allow the paddles 30 to rotate from a closed position 37 to a stretched position 36 such that It interacts with the sprocket wheel 50 to rotate it. The guide walls 14, extend from the return portion 82, to the output chamber 63, and ends Just before the abutment 12, so that the dosed position 37 of the paddles 30, are maintained till that point, to minimize upward resistance. It is to be appreciated that when the paddles 30 rotate to a stretched position 36 at the; abutment 12. the position of the paddle 30 is such that it provides a seal, so that there will be no backflow occurring, which would compromise Ihe driving force from the pressure chamber 21. The abutment 12 is positioned right after the top dead center of tine sprockā‚¬!t wheel 50 80 that the downward force acting on the sprocket wheel 50 by the paddlus 30 in a stretched position 36 is more effective.
Figure 2 shows a parspective view of the paddle 30 and linkage assembly. The linkage assembly is shown In the preferred embodtrrient us a linkage bar 34. The paddle 30 consists of a top surface 31 and a bottom surface 32. The top surface 31 Includes studs 39 so that the surface area of the top surface 31 Is Increased. This Is to ensure that more force can be obtained by the pressure exerted on the top surface 31 of the paaddle 30. The circumference of the paddle 30 further includes seals 33. to ensure a tight fit with the intsmal diameter of the semi-sealed tubular housing 60 when in a stretched position 36. The paddle 30 is hingedly connected to a linkage bar 34 on tha top surface 31, as seen In Figure 2. To link a subsequent paddle 30, the other and of the linkage bar 34 is fitted with an engagennent means 35 to attach to the bottom !;urtace 32 of the subsequent paddle
30. The engagement means 35 further includes a stop means 38 to prevent the subsequent paddle from freely rotating.
Figure 3 shows the engagement means 36 connected to a subsequent paddle 30. The stop means 3S is shown whereby ft stops the paddle 30 from over rotating.
The sprocket wheel, as seen in Figure 4, Includes a bearing cap 51 and shaft housing 52. The shaft housing can be coupled to any output generator for the generatior of power or electricity.
