Abstract
The Water Wall Turbine is a turbine device that consists of blades, cables, shaft, and sometimes flotation sections in the Blades for small (from under 1 KW) to large (multi MW) scale Energy Extraction (Potential and Kinetic) from currents, and to convert this Energy into Mechanical Energy for further conversion into Electrical Energy.
The Water Wall Turbine is designed for Renewable Energy Generation in the best Eco- and Bio-friendly way by making Barrages redundant through its large blades that move almost at the same speed as the Current.
The Water Wall Turbine is a Cylindrical structure that is less than 50%
submerged into the current and is designed to harvest the Energy, made available by the Head induced across the Blades, by the Blades, that restrictively rotate slower than the Current during the extraction of Energy from the current.

Claims (23)
1. The Water Wall Turbine is a turbine device comprising of a Shaft, Blades and, "Structural and Power Transferring" Cables, for Economical Renewable Energy Generation from Currents such as Freshwater Currents, Marine Currents, Tidal Currents, Air Currents, etc.
2. The Water Wall Turbine as claimed in claim 1 can harvest or extract Potential and Kinetic Energy, without any dependence on barrages or "catchment ponds".
3. The Water Wall Turbine as claimed in claim 2 can operate without Eco-unfriendly Barrages as it will generate its own Barrage effect, manifesting in the forming of a Head across the Turbine, making the Extraction of Potential Energy from the Current possible.
4. The Water Wall Turbine as claimed in 1 can operate in one or both directions for use in "Tidal zones".
5. The Water Wall Turbine as claimed in 1 is designed so that the Construction is relatively "Low Tech", so limited high precision machining will be required.
6. The Water Wall Turbine as claimed in 1 is designed so that no balancing, or dynamic balancing is required.
7. The Water Wall Turbine as claimed in 1 is designed so that the employment of Cables and their Power transferring properties in the structure, allows for the design and Construction of massive, but relative light, Water Wall Turbines. See Drawings Figure 1.
8. The structural cables of the Water Wall Turbine as described and claimed in claim 7 are also used to transfer the Power exerted by the water on the Blades, to the Shaft, causing the Shaft to rotate.
9. The rotating shaft claimed in claim 8 of small (from under 1 KW) to large (multi MW) scale Turbines, provides Rotating Mechanical Energy for conversion into Electrical Energy.
10. The Water Wall Turbine as described in claim 1 can also be pre-fabricated in modular form to facilitate the easier transportation by land or floated by sea, for assembling in situ (on the site).
11. The Water Wall Turbine as claimed in claim 1 is designed for high Renewable Energy Generation in an almost 100% Eco- and Bio-friendly way by making Barrages redundant through its large blades that move safely with, and almost at the same speed but somewhat slower than the Current.
12. The Water Wall Turbine as claimed in claim 1 can also in special applications incorporate flotation sections in the Blades.
13. The Turbine as claimed in claim 1 is a Cylindrical structure that is less than 50%
submerged into the current and rotates as a result of the pressure difference across the Blades caused by the Head formed by the Blades that restrictively rotate slower than the Current whilst extracting Potential Energy from the current.
submerged into the current and rotates as a result of the pressure difference across the Blades caused by the Head formed by the Blades that restrictively rotate slower than the Current whilst extracting Potential Energy from the current.
14. The Turbine as claimed in claim 1 can also, when required to be extremely strong and robust, be manufactured to consist of very strong pre-cast sections that are devoid of any parts that will hook, snare or entangle debris, trees or other objects.
15. The Water Wall Turbine as claimed in claim 14 can be manufactured from any practical Engineering Material, to do away with the single or multi stranded cables without deviating from the principle of Operation and Energy Extraction employed by the Water Wall Turbine.
16. The Water Wall Turbine as claimed in claim 1 can be manufactured by replacing the "Cables" with any practical Engineering Material in "Sheet Profile" form, to do away with the single or multi stranded cables, avoiding thereby any parts that will hook, snare or entangle debris, trees or other objects.
17. The Water Wall Turbine as claimed in 1 is positioned with the Shaft and Blades perpendicular to the Current flow, and therefore the Peripheral speed of the Water Wall Turbine rotating in the direction of the water flow, will be almost the same but slower than Water speed under operational conditions, resulting in absolute Bio-friendly operation.
18. This unique positioning and application of the Water Wall Turbine as claimed in claim 16 is in order to act as a "wall" confronting the Current, allowing for a higher Energy Extraction and Yield from the Current than Turbines with blades rotating in a plane, perpendicular to the Current direction.
19. This unique positioning and application of the Water Wall Turbine as claimed in claim 13, allows for all interactive and rotating parts used with the Turbine such as the Bearings, Gearbox, Alternator, etc. to be effectively well above the water level in order to eliminate submersed "pressure sealing problems".
20. The Water Wall Turbine as claimed in claim 1 is able to Extract Energy from shallow but fast flowing Currents.
21. The Water Wall Turbine as claimed in claim 1 is able to Extract Energy from Tidal Currents that varies from Zero meter depth, to 20 m plus during the Tidal cycles.
22. The Water Wall Turbine as claimed in claim 1 can be pre-fabricated in Modular form so it can be easily transferred to the site by land, or floated by sea by means of the Flotation Chambers, so it can be assembled in situ with minimum ecological damage.
23. The Shaft as claimed in claim 8 comprises normally of a part of the modular Blade section, and forms the shaft when all Modular sections are bound together, but it can be a separate structure or tube.
