III. Wave Air Pumps – WAP more
WAP-Construction The WAP is an inverted partially submerged in the water, with its top protruding above the water line, and having two (2) conic flare section at the bottom to guide water into a the small diameter cylinder. The inside diameter of the cylinder is 22 centimeters, and the flare diameter is 150 centimeters. Two sets of flares are provided as shown on the drawings. It is fixed to the floating structure or to the fixed structure, suction and discharge valves are above the water line. Compressed air output of the pumps is collected and fed to the air input of a turbo generator. WAP-Operation The WAP utilize the kinetic energy of the sea wave to compresses a small quantity of air to a high pressure, collect it in a piping network and feed it into the air inlet of a turbo generator. As the wave approached the WAP water is moving accelerating and moving upward due to the kinetic energy of the wave. As the water is moving up into the cylinder it imparts part of its kinetic energy to the trapped air in the cylinder and compresses it. The air is compressed to a pressure approximating 100 psi due to the difference in the inside diameters of the flares and the WAP. The compressed air is collected and fed to the air inlet of a turbo generator. Fuel is injected as needed to maintain turbo generator output during the whole wave cycle of 360 degrees. During the lee side of the wave, the water inside the WAP recedes down and creates a negative pressure. This negative suction pressure is channeled through a low pressure turbine, thus generating additional power. Compressed air technology and fogging (adding water vapor to turbine air inlet) are known and proven technologies. The system generates energy at normal fuel rate in the absence of waves, and at reduced fuel consumption inversely proportional to wave heights. WAP-Output Applying the law of conservation of energy, the developed power is comparable to that developed by the WWP.
