COEE DESCRIPTON
AN IDEA
Most Energy websites do not provide detailed technical information. They seem to act as a marketing tool. There is no wisdom in withholding information.
Developers are protected by Patents and by Intellectual Property rights. Moreover; due to the size of investment and to business acumen, no one would risk infringement on a Patent and/or Intellectual Property rights.
Lot of efforts and funds are wasted on systems that are in conflict with engineering principles, or no feasibility study is made to check for system constructability, viability and economy.
Our decision for Publishing System Details, Drawings and output would allow developers to scrutinize the system, improve system performance, provide collective knowledge or come up with a totally new system. Detailed Calculations are available upon request.
ONCE an offshore wind farm is planned it is worth investigating utilization of the offshore area to extract maximum marine energy. The REWGD system provides such systems as it extracts Wave, Wind, Ebb/Tide energy together with deep sea cold water for air conditioning. The REWGD system leads to the following:
1. “Construction Units” of modular offshore fixed construction support all systems and provide a dry deck for installation of different equipment for ease of operation and maintenance and solving the offshore mooring problem. The “Construction Unit” measures 17×18 meters, covers only six meters below mean sea level, and extends to the sea bed by means of structural columns at 18-meter spacing.
2. Direct drive energy extraction to generate power at the required voltage and frequency without the use of expensive and complicated speed controls and power electronics or inverters.
3. Removing the heavy weight generators of wind turbines from the top of the supporting mast to the “Construction Unit” dry deck, and using angle gear and/or universal joints for torque transfer to respective equipment, being a water pump or electric generator at the dry deck.
4. Removing the generators of Ebb/Tide turbines from underwater to the “Construction Unit” dry deck, and using angle gear and/or universal joints for torque transfer to respective equipment being water pump or electric generator at the dry deck.
5. Adding conic sections or shrouds to the Ebb/Tide turbine raises the water velocity above 2-meters per second and results in efficient energy extraction.
6. Physical layout of the “Construction Units” with respect to the incoming wave levels power and minimizes power pulsation due to wave energy extraction during the 126 out of the 360 degree wave cycle. This maintains the average power output for the 126 degrees over the whole wave cycle of 360 degrees. For example, a 4-meter hi wave provides a constant average output of 76-KW over the whole wave cycle.
7. A Deep Sea Cold Water Pump consisting of a pipe installed to the sea bed at 1,000 plus meters, where air is injected in the upper section of the pipe, to produce a column of aerated water column with smaller density than the outside water results in producing a net positive head at the pipe inlet and forces cold water to flow up the pipe where it is de-aerated and pumped as cold water for Air Conditioning.
SYSTEM OUTPUT
The estimated KW-Hour outputs per year are as follows:
1 – WGD System per “Construction Unit” measuring 17×18 meters, 776,192 KW-H/ Year.
6 – Ebb/Tide Turbine, with 2 meter cones 1,346,400 KW-H/ Year.
1 – Wind Turbo Generator with19 meter diameter sweep 859,900 KW-/H/ Year
Total Output 2,981,602 KW-H/ Year
