PROTOTYPE Renewable Energy Wave Pumps WAP, WGD, WWP General Prospective renewable energy developers are requesting information related to prototype manufacture and testing. Our response is: The REWP systems are based on simple and proven engineering principles. Detailed calculations are available upon request for review. Prototypes should be manufactured as full scale model and tested at sea under actual conditions. Manufacturing a small prototype for testing in a test tank does not provide the true performance of the REWP systems. All equipment and appurtenances are available on the market. The supporting structure of the Prototype is designed and installed as a “Construction Unit” that can be used for the full scale project as a permanent structure. The prototype shows sets of four (4) pumps or generators in line with the incoming wave. Prototype Construction The prototype is an offshore “Construction Unit” intended to test all the different pumps and generators described under the WGD system. The following prototype description is provided for a full scale model for testing at sea under actual conditions for all of the different REWP systems representing four (4) types of wave pumps; namely: 1. Two sets of pumps each consisting of three (3) Wave Air Pumps-WAP are installed in line with the incoming wave, total six.(6) pumps. 2. Two sets of generators each consisting of three (3) Wave Gear Drive-Generators-WGD-G are installed in line with the incoming wave, total six.(6) generators. 3. Two sets of Water Pumps each consisting of three (3) Reciprocating Wave Water Pumps are installed in line with the incoming wave, total six.(6) pumps. 4. Two sets of Water Pumps each consisting of three (3) Rotary Wave Water Pumps are installed in line with the incoming wave, total six.(6) pumps. 5. Two sets of pumps each consisting of three (3) Wave Air Pumps-WAP are installed in line with the incoming wave, total six.(6) pumps. 6. The pulley system is provided to allow for piston movement in the WWP reciprocating pump a distance of only two (2) meters for a wave height of eight (8) meters. At the same time increasing the internal diameter of the WWP from 22 cm to 44 cm to keep in line with the performance calculations. 7. The pulley system can be installed in the Vertical or Horizontal positions and fixed to the ceiling of the structure or installed under the structure deck. 8. The float for the WGD and WWP pumps is a hollow cylinder with an outside diameter of 150 centimeters and a height of 150 cm, or a float increasing to 220 cm O.D. and a height of 71 cm, may be substituted. The system can extract energy from waves as low as 75 cm up to 8 meters high Restrictions 1. Manufacturing and testing by prospective developers of the REWP prototype is subject to written permission and approval of drawings and to providing detailed reporting related to project and data collected. 2. Disclosure of detailed project information and location, detailed information as to developer and to Client. Controls The following controls are required: 1. Digital water flow meters to measure the quantity of water pumped by each pump and the total for four WGD pumps, with a digital pressure gauge at the main WGD pump discharge header. 2. Digital compressed air flow meters to measure the quantity of compressed air pumped by each pump and the total for four WGD pumps, with a digital pressure gauge at the main WGD pump discharge header. 3. The above data measures the quantity of energy extracted from the water wave. 4. If the budget allows, then Hydro or Gas/Fuel Turbines may be added to generate and measure the generated electric power. 5. Digital ammeters to measure the quantity of electric power generated by the first and the fourth WGD generator; and the total for four WGD Generators, with one voltmeter meter and frequency meter to monitor generated electric power. 6. A digital system to measure the sea state; that is wave heights and durations for a period covering the whole range of wave heights. 7. An electronic data processing system to acquire the above data and be able to process it against a time scale to provide true performance of the different systems. Services We are prepared to work closely with Clients to develop and execute the project: a. Take full charge and responsibility for developing detailed construction drawings, shop drawings, project execution and one year maintenance for all phases of the project. b. Act as Project Managers for developing, executing and bringing the project to successful completion within budget and as scheduled. c. If the Client elects to take full charge of the project by entering into a Contract and Agreement with a local contractor, then we will: I. Cooperate and coordinate any or all the following project activities. II. Provide main equipment and materials. III. Provide witness testing at manufacturer facilities for major equipment and materials. IV. Train local personnel for operation and maintenance of the project.
