Abstract

The invention refers to a Floating Energy Flywheel-carrying Cylinder (1), small to giant, for the production of electricity from renewable energy sources, that is the upward, downward and horizontal movement of sea waves, as well as the water's kinetic energy, flood and ebb-tide, sea currents and even river currents. It consists of a cylinder (1) that seats and rotates on the surface of the water (10a) on a rotation axis (2). Its circumference bears a great load in order to create great inertia that is supported on the water and not on the axis (2). The balance of both the rotation and anchorage is achieved through the axis (2). The cylinder (1) rotates and produces many ton meters of energy by the upward and downward wave movement, which it then transfers through its axis to an adjoining system of machinery and electric generator on the buoy (18). In order to exploit the water currents, the cylinder (1) is vested in all its length either with various types of fins (33, 34, 35), or with a worm screw (36, 36a, 36b), which can be extended lengthwise or by diameter, according to the needs.

Description

FLOATING CYLINDER WAVE ENERGY CONVENTOR

DESCRIPTION
The invention is about a Floating Energy Flywheel-carrying Cylinder, small to giant, for the production of electricity from renewable energy- sources, that is the upward, downward and horizontal movement of sea waves, as well as the water's kinetic energy, flood and ebb-tide, sea and river currents.
The already classically used flywheel of the compact wheel, due to its great inertia, is only used for the normalization of the speed fluctuation of a rotating system and it accumulates kinetic energy, when the angular velocity reduces, such as for example in single cylinder engines and in the initial movement of car engines (wheel).
Yet for large build-ups of kinetic energy, in an object with great inertia in the aforementioned flywheel, accumulation of heavy weight is required; its support on the two ends of the axis is tremendously difficult, and so the rotation of the said flywheel is very difficult too, if not impossible.
Furthermore, this is very easily attained with the Floating Energy Flywheel-carrying Cylinder (small to giant) that can accumulate small to large quantities of kinetic energy.
Thus the question of the body's support on the sea surface is resolved and the axes are only used for the balance of the rotation and anchorage.

Many inventions for the production of electric energy from sea waves, sea currents (flood and ebb-tide) as well as river currents are registered in the international bibliography, complete with full drawings and descriptions.
In addition, there is a special edition of a E.U. issue which refers to this subject and which includes lots of data with descriptions and drawings. There is likewise an edition of the Center of Renewable Energy Sources (KAPE, in Greek) that contains everything ever used to this day on floating or fixed constructions on river-banks.
There are even more inventions, small or large, yet secondary in use, like the KAIMAI
ship (Japanese - English - USA experiment) whereas through the compression and suction of air into chambers, due to the surge of the sea, could set in motion wind generators. Furthermore, the COCKEREIL CONTORIN RAFT can compress water for energy through water pumps or from the Gyroscope Power Take Off System through wave energy in order to produce power. In addition, there are inventions such as the Salter Modding - Duck - Wave Energy Convention System of Great Britain, the Bristol Cylinder and even the two blade propeller in Sweden for flood and ebb-tide, 20meters in diameter, producing electric energy of 80 Kilowatt (KW) only.

All the aforementioned systems were complex, costly and of large scale with yet low yield. Therefore they did not succeed and were abandoned.

The current invention of the Floating Energy Flywheel carrying Cylinder steps in to correct all disadvantages of the aforementioned existing devices for the production of electricity from renewable energy sources. Due to the fact that it disposes a large peripheral inertia and the rotation it acquires from the energy of the waves and of all sorts of water currents. So it can produce many ton meters of kinetic energy which is then transmitted to a system of mechanical devices of well-known technology and an electric generator, thus producing electric power of many kilowatts (KW) and even many Megawatt (MW).

The unit consisting of the Floating Energy Flywheel-carrying Cylinder and the buoy with the electric generator mechanisms will be anchored with all the required number of anchorages in order to remain in a fixed position while floating up and down.
In this fixed position there is a rotating mechanism of the cylinder on the axis' (2) two ends, producing kinetic energy from the waves.

One way to achieve great inertia of the Floating Energy Flywheel-carrying Cylinder is to place an inner concentric cylinder, creating thus a ring in between the cylinder (1) and so the ring is filled with concrete or water of high peripheral homogenous weight.
Alternatively the walls of the cylinder (1) can be constructed right from the start from a thick metal casing for greater peripheral strength.

Another way is to omit the second inner cylinder and cover the peripheral weight of the inertia throughout its length with iron beams or cement columns, fixed in any possible way.
A third way of creating a Floating Energy Flywheel-carrying Cylinder is to:
Construct on both ends of the cylinder's inner space an area with two inner diaphragms and in an equal distance from the cylinder's outer caps, following calculations. This area shall be filled either with cement or with water and it will constitute the bulk of the cylinder's inertia. The space between the two extreme volumes shall be empty.

For the cylinder's efficient rotation, without eccentricity hindering it, two identical half cylinders in weight and scheme are constructed. The sum of their length is the desired (length) of the whole cylinder. We place the two floating half cylinders heads together, composing one cylinder through a temporary joint. We let this construction settle and if there is eccentricity we repeat this process until we achieve full, nil eccentricity and we then join the two cylinder parts finally into one part.

Producing electric power through the surge of the sea Two wheels are fitted on the two ends of the axis of a functional Floating Energy Flywheel-carrying Cylinder. One is a clockwise ratchet wheel and the other a counter-clockwise one (bicycle clutch).
On each of these two wheels a sprocket chain is engaged. One end of the sprocket chain is extended downwards vertically with an anchor stem to the bottom of the sea where it is gripped. From the other end of the sprocket chain hangs a free weight - load.
This way, as a wave arrives the cylinder rises and the one ratchet wheel rotates the cylinder while the other spins freely (without making the cylinder turn).
When the wave recedes the cylinder descends, causing the first ratchet wheel to become inert and spin freely too, while the other ratchet wheel spins the cylinder assisted by its free load that descends. Thus, there is a continuous one way rotation of the Floating Energy Flywheel-carrying Cylinder. Until the next wave arrives the cylinder through its excess momentum, as calculated, continues rotating the electric generator founded on the next buoy at the extension of the axis of the flywheel-carrying cylinder where one or two universal joints are placed in between, thus producing electric power.
Another way to exploit the energy of many waves simultaneously is the following:
On a sea segment, following calculations, we fix on the calm sea water-line a tubular rotating axis with vertical anchorages, reaching the seabed with grips. The anchoring starts at the perimeter of the ball bearings in order to hold the axis at the calm sea water-line and to prevent its vertical movement. This anchoring is repeated at intervals throughout the length of the axis.
In addition, at these same anchoring points, double anchoring anchors immobilize horizontally the tubular rotating axis, left and right. Acting on this axis are buoys with appropriate (directional) band-break around the axis; each one of them has two levers -beams, (perpendicular to axis), on whose ends the brakes are applied with a powerful metallic band that surrounds the axis and ends once again at the buoy's beam.
(The buoys may have any solid geometric shape).
Throughout the cylinder's length, on one side, there are buoys that add rotations and great energy to the axis during the upward movement of the waves, and on the other side, there are also buoys on the entire length that add rotations and great energy during the downward movement of the waves.
All these buoys heave in a disorderly manner, as the waves too arrive in an irregular way, and it looks like many pistons are at work, which however, each one separately from the other add rotations and great energy without being affected by the rising or the descending buoys. Thus, at any given time, there is a random sum amount to the benefit of rotation. And great energy on this axis that the tubular axis transmits to the axis of the Floating Energy Flywheel-carrying Cylinder through a system of pulleys and (closed) sprocket chains and the end ratchet (one way bicycle clutch). The process is then normalized through its inertia upon the Floating Energy Flywheel-carrying Cylinder, which produces kinetic energy, transmitting it in turn through its axis to the axis of the machinery and the buoy's electric generator by an intermediate universal joint, thus producing many Megawatt (MW).

Electric energy production from renewable energy sources, i.e. sea currents, flood and ebb-tide and even river currents.

Floating Energy Flywheel-carrying Cylinder for the aforementioned energy sources from water currents. It is vested on its length, depending on its usage, either with transverse fins, linear radial along the entire cylinder length, or angular fins -semicircular or curved - throughout its length; this vesting conduce the Floating Energy Flywheel-carrying Cylinder to act as a light type "PELTON" propeller.
Also throughout its length can be vested with a worm screw of one, two or three threads of hyperbolic curve where the flywheel-carrying cylinder acts as a light type "KAPLAN"
propeller.

To construct the worm screw we cut concentric discs from a stainless plate appropriately thick, cutting them radially, interrupting the continuity of the disc once.
We connect the two disks by bonding the end of the first one with the beginning of the second (the next one). When this is spread on the body of the flywheel-carrying cylinder, a perfect screw of hyperbolic cross-section is formed which rests on the thread's two ends. When the thread is stretched, it braces the screw like a boa constrictor and stabilises itself.
For the flood and ebb-tide we use the vesting with vertical fins.
The cylinder is anchored with at least four anchors and we connect its axis by extension of the buoy that has the mechanism and the electric generator so as to produce electricity.
The vertical fins render rotation to the cylinder. For example the flux of the ebb-tide with clockwise rotation which are therefore transmitted to the electric generator.
When the ebb-tide stops and flood arrives from the opposite direction, the vertical fins of the flywheel-carrying cylinder rotate it counter clockwise to itself, immediately through the connection of the clutch mechanism to the equipment buoy. It has an automatic system that acts and the clockwise rotations become counter clockwise for the generator.
The buoy is well anchored in alignment to the floating flywheel-carrying cylinder's extension.
We could however, instead of this construction, place otherwise two floating flywheel-carrying cylinders. Vested with a worm screw funnel, according to our calculations, of one, two or three threads, in about a 60 degree angle to the direction of the flood and ebb-tide current. And in a fixed position with double anchorages, so that they remain in their precise location and each cylinder will work in turn, either the ebb-tide or the flood.
In the continuation of the axis of each worm screw there will be a buoy with the equipment and the electric generator. These will be doubly well anchored.

For the rest of the river currents, depending on the case, floating flywheel-carrying cylinders vertical to the current flow are used. With the appropriate row of fins or preferably with an oblique positioning of a worm screw floating cylinder, which has the possibility of being extended as much as the existing current permits (and the river depth ).
In this case, the anchorages are all in one direction to the current's upstream. Here too, in all cases, the equipment buoy is set on the extension of the axis of the floating flywheel-carrying cylinder.
When it concerns a floating flywheel-carrying cylinder small in length and the space in the river is limited in order to fit the equipment buoy and the electric generator, then all the necessary equipment and the electric generator can be placed on an elevated platform, over the flywheel-carrying cylinder, standing accordingly on posts, on the cylinder's rotation bearings, with the required cross-beams with the chamber's support truss, in a small pavilion. This can also be done above the water level supported on the platform's posts and cross beams in proper distances. Four buoys will keep the balance of the platform on the generator's axis. The cylinder's revolutions are transmitted to the generator on the terrace by a sprocket chain.
The floating flywheel-carrying cylinder for the water currents of the sea and of the rivers, with the casing of the curved, oblique, vertical fins, or the one, two or three thread worm screw I when they rotate out of the currents of the semi-immersed cylinders and due to the flow property from the water surface at the cylinder's point up to its lower part, the currents gain acceleration. For this reason there is a better yield than other systems.
The invention is described below using an example per each application and with_ reference to the attached designs, which:
Figure 1 presents a front view of the floating energy flywheel-carrying cylinder (1), with the base of that side (3), its rotation axis (2) and the seating of the entire system on the virtual sea generatrix bearing (10a).

Figure 2: presents a perspective view of one front base (3) and the length of the floating flywheel-carrying cylinder (1), its rotation axis (2) and the lengthwise expanding possibility (1a), the ideal and even bearing of the cylinder on virtual sea generatrix bearing (10a) , due to the water's incompressibility.

Figure 3: presents a longitudinal cross-section of the floating flywheel-carrying cylinder (1). Where the main exterior cylinder (1), the interior cylinder (8) that separates the interior in two sections: the central (8b) consisting the void displacement space and the part between the two cylinders, the peripheral section (zone) (8c) that is filled either with concrete (7) or with water (9). That weight of the cement or water constitutes the great inertia of the flywheel-carrying cylinder. The radial cross beam (8a) may be added if the walls need support.

Apart from the ideal bearing, due to the water's incompressibility with the side (10a) as on a virtual sea generatrix there is yet another advantage by its bearing. Due to the water's viscosity and its molecular composition, it is like its entire surface is seating on thousands of ball bearings' (virtual massive ball bearings) (10). And the cylinder's rotation on its axis (2) is easy since the axis (2) does not uphold any of the cylinder's weight but only exists for its rotation, its equilibrium and its anchorage (20), setting off from its rotation ball-bearings (21).
The start. of the cylinder's rotations is achieved with a peripheral force (4), approximately equal in weight to 1 hundredth (1/100) of the total weight of the inertia and of the structure.
Should we omit the structuring cast cement (7) or water (9) and if therefore we do not install the cylinder (8), we can cover the inertia's peripheral weight inside, circumferentially on. cylinder (1). With the cylinder's own body, if it is constructed, as mentioned before, with a thick coat (1 b) over its entire surface.
Otherwise, the perimeter is covered through its whole length either with very heavy iron girders (5) one next to the other or with concrete piles (6) secured technically in any other way.

We can have a new form of peripheral weight, If we install in equal distance from the cylinder's bases (3), following calculations, two diaphragms (3a), at the same level as the bases (3). Fixing them in a waterproof way, and filling the space (3c) between base 3) and the diaphragm (3a) of each side, either with a mass of cast concrete or with water, , Fig. 40.

Figure 4 presents a frontal lengthwise cross-section perspective view. Figure 4 is a perspective account of Figure 3.
Figure 5 shows a lengthwise view of the Floating Energy Flywheel-carrying Cylinder with the beginning and the process of the construction, the balancing and concluding to one cylinder, without any rotational eccentricity.

For this, two identical half cylinders (A) and (B) are constructed with the same material and construction plans; afterwards they are loaded with the appropriate weight (oads that will form their inertia; the cylinder's heads are then fitted together, Figure 5, and once they have settled from any possible eccentricity, they are marked with the letters (a - a) on both halves. Both halves are then fastened together temporarily through any kind of system (12) on four points, fastening them crossways, doing the same in the diametrically opposite side.
If the eccentricity persists, the aforementioned process is repeated at a greater distance of the lines (a - a) (Figure 6) and attach them crossways to the new position of points (12c). If the eccentricity persists, the aforementioned process is repeated in the new positions (a - a) (Figure 7), attaching points (12d) crossways. After the distance (a - a) is set in a new position and provided the balancing has nil eccentricity, the two cylinder halves (A) and (B) are joined and applied to the joint (11). Then with a strong metal strip (12), the entire joint (11) and strip (12) are peripherally welded. Now the floating energy flywheel-carrying cylinder is ready to use.
Figure 8 shows a floating energy flywheel-carrying cylinder in a rotation mode through the sea waves, its connection to a buoy (18), where a= clutch, b = gearbox, c =
revolution control, d= electric generator and inside the pavilion any other known technology instruments, cylinder and buoys properly anchored through anchors (20), allowing the cylinder's movement up and down on the spot.

Figure 9: A front view of the flywheel-carrying cylinder. It shows the application of a gear wheel on its axis (2), fixed onto the base (3) of the cylinder that disposes a counter-clockwise rotating mechanism with a ratchet (one way bicycle clutch) (13de).
Thus enabling the cylinder to rotate when the wave rises and to spin freely when the wave recedes. The gear wheel's mechanism is clockwise here.

Figure 11: The course of the gear wheel (1 3de) from its lowest position (b) where it transfers the balancing weight (15), to the highest point (a2). The cylinder had a clockwise rotation (22).

Figure 12: This shows the opposite course from the other end of the axis of the cylinder (2) where the ratchet (one way bicycle clutch) (13ar) is fixed. As the right one (13de) was rising this one was spinning freely. Now that the cylinder will start descending as the wave recedes and move from position (a) to the low position (b), the weight (16) of the sprocket chain (14a) will also move downward, making the cylinder spin with the same rotation (22). This way, the flywheel-carrying cylinder has constant rotation from each wave's arrival and departure.
During a dead period of about three seconds (3") before the Mediterranean wave arrives and the spins resume, the flywheel-carrying cylinder (1), since by calculations it disposes greater sufficiency of kinetic energy than the electric generator' complex of instruments, continues to rotate the generator through its momentum.
Figure 10 shows a plan view of the entire complex with its strong anchoring (20) that can be reinforced if necessary.
The anchoring (20), Figure 9, starts at the ball bearing (21) of the axis (2) and the anchor (20) is connected to the exterior ball bearing casing via a strong collar that tightens up the ball bearing.

Figure 13 shows a long axis (23) which on one side is surrounded by a large number of upward buoys (24) and on the other side by a large number of downward buoys (25). In this way the axis (23) and the buoys (24 and 25) cover simultaneously a large area of many waves and add to the axis (23) rotations and great energy from waves that arrive from any wind direction.
Double anchoring (20), left and right, at given intervals, keep the axis (23) aligned. The axis (23) is held at the calm sea waterline, Figure 17, through vertical anchoring with grip (17) at given intervals of its length. Keeping the axis at the waterline level allows the buoys to delineate the biggest possible rotation arc of the axis (23).
The upward and downward movement of the buoys is disorderly, as disorderly is the arrival of the waves. Each buoy acts on its own without hindering the action of the others. So, there comes a time when the action of a group of buoys, regardless of which one, coincides on the axis with the advantage of great energy and rotation.
Figure 14, side view and Figure 15 ground plan, show buoys (24 and 25) similar in shape and in dimensions, either cylindrical, either cubic or conical etc, of a fixed capacity where the buoys (24) are secured on two levers - beams (26) and the buoys (25) on two angular levers - beams (27).
The buoys (24) are empty and act upwards with the wave pressure, whilst the buoys (25) are half filled with water in order to float on one hand and act downwards with their weight as the waves recede on the other: This way there is a constant advantageous action.
A strong metal strap (28) is applied at the ends of the lever-beams of all the buoys, surrounding the entire perimeter of axis (23), ending up onto the same lever-beam, connected to it with a micrometrical regulating mechanism (29) of the breaks, with a second type lever. The fulcrum is the lever's end on the axis. The action of power is the buoy and the implementation of the braking work is point (29).
Instead, there could be a bolt tightening device (nut) with ratchet, or a gear mechanism with ratchet (one way bicycle clutch).
Strong metal perimetric straps (30) support and connect the buoys with the lever-beams.
The vertical anchoring of the cylinder's axis start from it clasping a ball bearing (21) which is there to ensure its unimpeded rotation. A gear wheel (gear) (13a) is embodied at the end of the axis (23) towards the flywheel-carrying cylinder.
A-closed sprocket chain (14a) is fitted around this gear surrounding it, setting in motion another double gear wheel (gear) (13b) upon which a closed sprocket chain (14b) is fitted, surrounding it, surrounding also the gear wheel (gear) (13) with a backwards rotating ratchet (one way bicycle clutch) which (13) is.on the axis (2) of the floating energy flywheel-carrying cylinder.
The double gear (13b) rests on a particular axis (32) with its two extremities free. For its rotation it has one ball bearing (21) each; upon which hangs a weight (31) with a chain that surrounds the ball bearings (21). These two weights (31) are suspending, but keep the entire suspension system, double gear (13b) and chained belts (14a and 14b) in a vertical state as well as in a functioning position.

The virtual triangle between the axis (13a), (13b) and (13). When the flywheel-carrying cylinder moves up and down due the surge of the sea changing the angle of the triangle and consequently the triangle's shape, continuing its rotation due to the balance provided by the weights, as we have mentioned before, keeping thus the system in a functioning position.
The length of the straps should be such as to cover 2 - 3meter waves (storm).

Figure 16 (side view): The Floating Flywheel-Carrying Cylinder is connected from its axis (2) via a four ball bearing universal joint (14) to the axis of the instruments on their buoy (18) which also includes a small pavilion to protect them. There is also the anchoring (20).

Figure 19, general ground plan presenting the entire complex, the layout of many buoys (24 and 25), the very long axis (23), the sprocket chain's mechanism (14a and 14b), the floating energy flywheel-carrying cylinder (1), as well as the buoy (18) with all the machinery and the generator for the production of electricity. The generated electricity will be transferred to the shore via an underwater cable.

As far as sea water currents are concerned, flood and ebb-tide and river currents, the floating energy flywheel-carrying cylinder, according to its use, is vested (fig. 20) in its entire length with vertical, radial fins (33), e.g. for flood and ebb-tide.
For the remaining types of currents (Fig 21) the cylinder is vested in its entire length with either angular fins (34) or semi-circular - curved ones (35) and thus the cylinder behaves like a light type "Pelton" propeller. Finally, the vesting in Figure 23 with worm screw fins (36) (Fig 28) with two coils (36a) (Fig. 30) and also with three coils (36b) (Fig 29) that act as a light type "Kaplan" propeller.

All the aforementioned cylinders and their casings, due to their immersion in water (Fig 24), as the water currents with a relative velocity (a) fall on them during their impact on any of the cylinders mentioned earlier, travel the distance from the point of impact of the current's surface (49) to the lower part of the cylinder (50) with acceleration (al) in order to cover this vertical distance. Thus the cylinders have a greater yield.

Discs are cut from an appropriate metal. sheet to construct a one thread screw (36), where:
r = cylinder radius disc inner radius = (r x 2) disc outer radius = (r x 2 x 3,545) fin width = disc outer radius - disc inner radius = rr Two thread screw (36a):
disc inner radius = (r x 2) disc outer radius = (r x 2 + rr/2) fin's thread width = (rr/2) Three thread screw (36b):
disc inner radius = (r x 2).
disc outer radius = (r x 2+-rr/3) thread width = (1r/3) The discs are cut radially (Fig 26) and the thread is assembled by uniting the end (b) of each disc to the end (a) of the other disc, Fig. 25.

When the thread is spread on the body of the cylinder (1) a worm screw (27a) is formed with all the mathematical data, pitch - diameter etc.
Each thread is fixed at its beginning and its end firmly in any way, e.g.
welding, etc and also in between occasionally to secure it better.

The curve which will be created by the discs, when they will spread on the said cylinder's periphery, is a worm screw of hyperbolic curve. And the other elements, e.g.
pitch, disc height etc will be formed automatically on their own and normally for each diameter of the cylinder and also by the thread's stretching on the cylinder's body. Each coil embraces tightly the cylinder like a boa.
Additional adjacent flow forces come into play due to the properties of the worm screw (27a) created by each coil during the cylinder's rotation, and also by the formed eventual coil and cylinder diameter.
The flywheel-carrying cylinder has the greatest yield, because apart from its gained acceleration due to the cylinder's submersion, it also has the advantage of the incoming said adjacent forces (a) Fig. 27 during the cylinder's rotation, due to the special curve the funnel is forming.
The thread is fixed at the beginning and end of its placement and also in between for security reasons and greater robustness.
For Example: In a screw cylinder, on a 1 mZsurface, enters flow for energy 1:10m2 of water current, whilst in a 1 rn2 perfect two-fin propeller enters 0.60m2water current for energy. Consequently there is a 40% energy loss.

For flood and ebb-tide we put together (Fig 20) a floating flywheel-carrying cylinder, with the appropriate length and diameter for a given place. The cylinder is vested with radial vertical fins (33). The cylinder is then positioned vertically to the currents. The cylinder's axis is then placed together with the axis of the buoys' machinery (18) via a ball-bearing (21) universal joint (19) and the whole system (36) is anchored with double anchors (20).

If we assume that the fan wheel (33) (Fig 36) turns clockwise with the current of the ebb-tide (40) and so does the generator when the current is reversed with the flood (39), the fan wheel will rotate counter clockwise. For this reason another automatic mechanism (a1) is added to the mechanism's buoy (18) (Fig 34) together with the clutch (18a) that converts the counterclockwise rotations to clockwise ones for the generator's function.

Instead of the previous solution, for flood and ebb-tide one can place a floating screw flywheel-carrying cylinder on the ebb-tide current (40) (Fig 31) with a vested screw of one thread (Fig 28), of two threads (Fig 30) or three coils (Fig 29). The selection is determined depending on the local current conditions. The cylinder will be positioned in a 60 angle at the ebb-tide current (40) and will be anchored with double anchors (20), so as not to move during the flood (39).
An identical floating screw flywheel-carrying cylinder (Fig 32) will be placed for the flood (39), again in a 60 angle at the flood current (39).
So during the ebb-tide the flywheel-carrying cylinder of the flood (39) will remain motionless while in the flood it is the flywheel-carrying cylinder of the ebb-tide (40) that stays motionless.
Thus, two cases follow: the connection of the screw axis via a universal joint (19) with a ball-bearing (21) and the connection with the axis of the generator and machinery on the buoy (18) (Fig 31 and Fig 32).

For sea and river currents the floating screw flywheel-carrying cylinder is fitted (Fig 33) with a vested screw of one threads (36) (Fig 28), two threads (36a) (Fig 30) or three threads (36b) (Fig 29) depending on the local conditions of each current. The anchoring (20) is only done on the current's upstream.

In case the river's width, or for any other reason e.g. sailing in rivers, does not allow space for the buoy with the machinery and the generator, these may be placed (Fig 27 - side view) on an elevated chamber (52), propped up over the flywheel-carrying cylinder.
The chamber (52) is suspended to this end with two posts (43) supported on the axis' (2) ball-bearings (21) with a tightening socket on the ball-bearing.
The flooring of the chamber (52) is developed from - post to post (43) with the appropriate cross beam (41) but high enough so as not to hinder the rotation of the fan wheel. A little over the water level a horizontal beam (Fig 38) develops, fixed at its base (47) together with the post (43) and on both posts. It is further reinforced with diagonal cross beams (47a).
Four buoys (44) are attached to the ends of its beams, thus preventing the pavilion from turning over. A small pavilion (51) is created on this chamber to protect the machinery and the electric generator of known technology.
The fan wheel's rotations are transmitted to the machinery axis with a sprocket chain (14). A ladder (45) is used to go up to the pavilion.
The generated electricity is conveyed towards the riverbank through an aerial cable (53).
A cross beam (48), Fig 39 - construction ground plan, connects the buoys vigorously.
The anchoring that starts at the fan's rotation ball-bearings is done at the current's upstream. In case of drought, therefore lack of water in a river, the whole system (38) lies at the bottom of the riverbed with its existing four legs - webs (46) and so the fan is not destroyed.

All the aforementioned floating energy flywheel-carrying cylinders and their anchoring (20) go up and down according to the water level each time. All the accessories at issue in the sea are either of stainless steel or are protected from rust (oxidation) with special paints.

For its rotation from one wave, it bears on one end of its axis (2), in contact with the cap (3), a gear wheel (13de) with a clockwise ratchet (one way bicycle clutch). A sprocket chain (14de) is placed on it whose one end is gripped to the seabed (17) and with a weight suspended on its other end (15). On the second end of the axis (2) there is a wheel (13ar) with a counter clockwise ratchet (one way bicycle clutch) and on top of this a sprocket chain (14ar), that has one end gripped to the seabed (17) and a weight placed on the other (16).

2. Floating Energy Flywheel-carrying Cylinder, according to Claim 1 for its rotation through multiple waves of great area exists an auxiliary complex that consists of a very long tubular axis (23) that is kept on the waterline through a series of gripped (17) anchorages (20) via ball bearings (21). On one side there are upward buoys (24) with two levers - beams (26) that are connected to the buoys through the belts (30). There are metal braking straps (28) at the end of the levers and a regulating braking mechanism (29). On the other side there are downwards buoys (25), with levers -beams (27), buoy joints (30) and metal straps (28) at the end of the levers with a braking mechanism (29).
The concentrated energy from the buoys on the axis (23) is transmitted to the rotation axis (2) via wheels and sprocket chains (figures 17, 18, 19) and then to the flywheel-carrying cylinder and afterwards to the buoy with the machinery and the electric generators.

3. Floating Energy Flywheel-carrying Cylinder, according to Claim 1 for its rotation through all sorts of water currents is qualified by the fact that the cylinder (1) is vested following selection with radial (33), angular (34) or concave (35) fins that extend in all its length for the currents' vertical impact. In this case all anchorages take place in the upstream except in the case of ebb and flow where the anchorages are on both sides.
Also, in the case of ebb and flow a mechanism to change the direction of the rotation (a1) is set on the buoy (18). For the rotation of the flywheel-carrying cylinder, besides vesting the cylinder with fins (1), the cylinder (1) may be bested with a worm screw (27a), with a choice of one (36), two (36a) or three (36b) threads, positioning the cylinder (1) at a 60° degree angle to the current. In flow and ebb two worm screws are used, one for each current direction. The anchorages are towards the upstream, except in the case of ebb and flow where they are in both directions.

4. Floating Energy Flywheel-carrying Cylinder, according to Claims 1 and 3, is qualified by the fact that the construction of the screw is done by cutting the disks as follows:
a) One-thread screw (36) (figure 28): The metal sheet is cut with an inner radius 2r (r =
cylinder radius) (figure 26), outer radius 2r x 3,545 and a fin width of outer radius minus inner radius = .pi..
b) Two-thread screw (36a) (figure 30): The metal sheet is cut with an inner radius 2r (r =
cylinder radius) (figure 26), outer radius 2r + .pi./2 and a fin width of outer radius minus inner radius = .pi./2.
c) Three-thread screw (36b) (figure 29): The metal sheet is cut with an inner radius 2r (r = cylinder radius) (figure 26), outer radius 2r + .pi./3 and a fin width of outer radius minus inner radius = .pi./3.
The discs are cut out radially (Fig 26) and the fins are put together by connecting the end of one disc (b) with the beginning of the other disc (b) (Fig 25). When the fin is laid out on the body of the cylinder (1) it forms a worm screw (27a).

5. Floating Energy Flywheel-carrying Cylinder, according to Claims 1, 2 and 3, is qualified by the fact that in case of lack of space for the machinery and the generator, they are set in an elevated platform (52) with a small pavilion (51), over the cylinder (1) (figure 37). More precisely, two posts (43) are placed at the cylinder (1) axis' (2) ball-bearings and on their top evolve the platform where the machinery and the pavilion will be placed. To balance this construction, four beams (47) and (48) are placed -which form a rectangular parallelogram - on top of which the four buoys (44) will rest. The vertical posts are supported with cross beams to the horizontal beams (47).
The rotation of the axis of the machinery and the electric generator is achieved with a sprocket chain (14) from the axis of the flywheel-carrying cylinder. The anchoring (20) is towards the upstream.
