PROPOSAL

1. Wave Water Pump - WWP Feasibility Study

Lifts a small quantity of water to a high head due to the Potential Energy of the incoming wave, collects it in a piping network and feeds it to a hydro-turbo generator to produce electric power
A set of pumps up to ten and a mile wide may be installed in line with the incoming wave to extract most of its energy.

2. Wave Air Pump - WAP Feasibility Study

Compresses air due to Kinetic Energy of the incoming wave, collects it in a piping network and feeds it into the air inlet of a turbo generator. Fuel is injected as needed to maintain turbo generator output irrespective of wave heights.
Utilizes an existing power plant, or a new power plant close to the shore.
Ideal for off-shore wind turbine farms, as it utilizes the off-shore wind turbine supporting structure as a Wave Air Pump at negligible cost.

3. Wind Turbine Pump – WTP

Present design of wind turbines call for installing 3-blade turbines to directly drive a generator installed at the top of the wind turbine supporting structure.
One firm boasts that it had developed a 100 meter diameter wind turbine and installing a 5-Mega Watt generator weighing 403 tons at the tope of the wind turbine supporting structure. This is an engineering achievement, to provide the highway to transport the equipment to site, lift a 403 ton generator and install it at a minimum height of 70-meters above ground level. Many reasons make this as ridiculous: Cost, Frequency Stabilization, Operation and Maintenance, and dependability; since NO Wind NO Power Output.
A simpler way is to make the wind turbine directly drive a fluid pump installed at the tope of the mast, transmit the power down the mast to a ground based generator. This technology is known and developed.
Another method is to have the fluid power drive an air compressor at ground level, collect the compressed air from more than one wind turbine and feed the compressed air to the air inlet of a turbo generator. Fuel is fed according to power requirements and is used to stabilize frequency. This is a known and proven technology.
In this manner power is generated irrespective of availability of wind and is more economical than any other proposed systems.

BRIEF DESCRIPTION

Wave Water Pump (WWP) - General

· When you see a wave go by you think of it as the water moving. It is not the water it is the energy within the water that is making it move.

· The energy within the wave has a high flow (Q) at a low head (h).

· The idea is to convert this energy to a low (Q) at a higher head (H) and collect enough Q for operating a turbo-generator

WWP - Pump - Construction

· The WWP consists of a large Major Float at the sea surface, connected by flexible lines and a rod to a piston inside a submerged small diameter reciprocating water pump. The WWP is anchored to the sea bed and kept vertical by a submerged Pump Float.

· Suction and Discharge Check Valves regulate the flow of water into and out of the pump.

· Pumped water is collected in a piping network at the sea bed and discharged to a hydro turbine to drive a generator.

WWP - Pump – Operation

· The WWP converts the volume of water at a low head in a wave to a small quantity of water to a much higher head, collects it and feeds it to a hydro turbine to produce power.

· As the Major Float moves up and down with the incoming wave it can develop an uplift force of 2.65 tons, which acts on the pump piston to raise 29 liters to a height of 90 meters.

· Installing a set of 10 WWP’s in line with the incoming wave and increasing the outside diameter of the Major Float and keeping the same ID for the pump would extract up to xx % of the incoming wave energy.

· A summary of extracted energy with respect to wave height is shown in Table 1.

WWP - System Construction

· Installing 333 sets of 10 WWP’s in an area of 30x1,000 meters, can extract between 0.7 and 27 mega watts for waves ranging from 1 to 4 meters high

· To compensate for the reduced energy of the wave, the Major Float dimensions are modified by increasing its diameter and reducing its height to keep the total uplift constant.

WWP – Calculation

· A set of 10 pumps in line with the incoming wave can extract between 2.09 and 81.76 KW for wave heights ranging from 1 to 4 meters.

· Table 1 shows energy extraction as a function of wave heights.

WWP – Storm Conditions

· The WWP system can withstand storms and is safe to navigation. Red pumps protruding above the water are clearly visible during the day, and Red Flashing Lights provide warning to navigation during the night.

WWP – Feasibility Study

· The WWP system is intended for large scale power generation suitable for connection to a public utility network.

· Site investigation should be developed to determine the frequency and duration of waves on hourly basis for a period of one year. This determines the amount of kilowatt hours that can be produced during a year.

· The contour of the sea bed to be logged up to a water depth of 15 meters.

· Seasonal and daily sea levels to be logged for a period of one year.

Wave Air Pump (WAP) - General

· When you see a wave go by you think of it as the water moving. It is not the water, it is the energy within the water that is making it move.

· The Potential Energy within the wave has a high flow (Q) at a low head (h).

· The Kinetic Energy within the wave is in the form of water accelerating upwards and is equal to the Potential Energy.

· The idea is to convert this KE into compressed air collect it and feed it to the air inlet of a fueled turbine to produce power.

WAP - Pump - Construction

· The pump is cylinder shaped, closed top, open bottom, protruding above sea level, kept vertical by a pump float and anchored to the sea bed.

· The pump has two flared conic sections, one attached to the bottom of the pump and the other attached to the pump two meters above the bottom and covers the slotted pump section located one meter above the bottom of the pump.

· Suction and Discharge Check Valves regulate the flow of air into and out of the pump.

· A Discharge Line is fixed to the pump outer casing and runs down to connect through an elbow and flexible couplings to the piping network that feeds compressed air to the air inlet of a turbine.

· The WAP has no moving parts, is light weight and needs a sea level of 15 meters. Therefore; it has minimum construction cost, and practically no maintenance costs other than visual inspection.

WAP - Pump - Operation

· The pump converts the kinetic energy of a wave into compressed air, collects it and feeds it to the air inlet of a fueled turbo generator.

· As a wave approaches the WAP, the large amount of water rushing and accelerating upward inside the flared conic sections is confronted with a reduced area and imparts its Kinetic Energy to the air trapped in the upper section of the pump to deliver a small quantity of air at high pressure.

· Suction and discharge Check Valves regulate the movement of air into and out of the pump.

· The compressed air is collected by a piping network and fed to the air inlet or combustion chamber of a fuel turbo generator.

· The energy in the compressed air would be manifested by the increased efficiency of the turbo generator, leading to less fuel requirements for the same power output. The principles of compressed air and adding water vapor (fogging) to turbine inlet air or combustion chamber are well known and established in the turbine industry.

WAP - System Construction

· Installing 333 sets of 10 WAP’s in an area of 30x1,000 meters, can extract between 0.7 and 27 mega watts for waves ranging from 1 to 4 meters high

· To compensate for the reduced energy of the wave, the Flared Conic diameters are increased to maintain the same pump power output.

· Fuel Turbines consume a good part of their output to compress the turbine inlet air.

· A dilemma exists for wave, wind and solar energy: If you have the renewable energy source, you have power output, no energy source, no power output. The WAP system resolves this dilemma.

· This system provides dependable energy irrespective of availability of waves or wind energy.

· The turbo generator operates with normal fuel consumption when no waves or wind energy are available, and operates at reduced fuel consumption when these energies are available.

WAP – Calculation

· A set of 10 pumps in line with the incoming wave can extract between 2.13 and 83.2 KW for wave heights ranging from 1 to 4 meters.

· Table 2 shows energy extraction as a function of wave heights.

WAP – Storm Conditions

· The WAP system can withstand storms and is safe to navigation. Red pumps protruding above the water are clearly visible during the day, and Red Flashing Lights provide warning to navigation during the night.

WAP – Feasibility Study

· The WAP system is intended for large scale power generation suitable for connection to a public utility network.
