Utilize the wave energy to pump a small quantity
of water to a high head, which is collected in a piping network and
fed to a hydro-turbo generator to generate electric power at
competitive cost.
A set of pumps up to ten and a mile wide may be
installed in line with the incoming wave to extract most of the wave
energy.
Wave Air Pumps - WAP
Utilize the kinetic energy of the wave to
compresses a small quantity of air to a high pressure, which is
collected in a piping network and fed into the air inlet of a turbo
generator.
Fuel is injected as needed to maintain turbo
generator output irrespective of availability of waves.
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.
Dependability of producing energy irrespective of
availability of wave energy is achieved by controlling injected fuel
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.
The WAP is ideal for sea water aeration. The WAP
may be used to inject compressed air into the sea to enhance the
oxidation process of organic materials.

BRIEF DESCRIPTION
– WWP
WWP -
Construction
The WWP consists of a large Major Float
floating 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 run at the sea bed and discharging into hydro-turbo
generator to provide power at required voltage and
frequency.
The WWP needs a minimum water depth of 14
meters.
Installing sets of 10-Pumps would
increase wave energy extraction.
Discharge
pipes and cross dummy piping are in integral part of the
system mooring.
WWP – Operation
The Major Float moves up and down with
the incoming. For a 4 meter high wave the large volume
Major Float develops an uplift force up to 2,650 kilo-grams
that acts on the piston of a small diameter piston pump to
extract an average of 119 liters per cycle to 50 m head.
This is equivalent to extracting 58.14 KW from a 108 KW
incoming wave at an extraction efficiency of 53.83 %.
WWP - System
Construction
A WWP field consists of multiples of
10-Pump sets to provide the required generator power output.
Installing ten sets of 10-Pumps each
(total 100 pumps) occupies 13.5 by 30 meters space. Water
pumped to 50 m and generator output are shown below.
System costs depend upon location, power
output and Client requirements.
The system output in KW-Hours per year is
the sum product of generator output in KW and the respective
wave height durations in hours per year. This information
would provide system yearly gross income.
The above data determines system
viability and profitability.

BRIEF
DESCRIPTION – WAP
WAP -
Construction
The pump is
cylinder shaped, small diameter, closed top, open bottom,
protruding above sea level, kept vertical by a pump float
and anchored to the sea bed.
The pump has
two large diameter 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 a 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 14
meters.
The WAP has
minimum construction cost, and practically no maintenance
costs other than visual inspection.
Discharge
pipes and cross dummy piping are in integral part of the
system mooring.
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 thus transferring part of 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 less fuel
consumption for the same power output, thus leading to
increased efficiency of the turbo generator.
The
principles of feeding compressed air and fogging (adding
water vapor) to turbine inlet air or combustion chamber are
well known and established in the turbine industry.
WAP - System
Construction
A WAP field consists of multiples
of 10-Pump sets to provide the required generator power
output.
Installing ten sets of 10-Pumps
each (total 100 pumps) occupies 13.5 by 30 meters space.
Air Compressed to 100 psi and generator output are shown
below.
System costs depend upon location,
power output and Client requirements.
The system output in KW-Hours per
year is the sum product of generator output in KW and the
respective wave height durations in hours per year. This
information would provide system yearly gross income.
The above data determines system
viability and profitability.
Fuel
Turbines consume a good part of their output to compress the
turbine inlet air.
The
WAP system resolves the dilemma of having generator output
only when a renewable energy source is available. No energy
source, No power output. The WAP 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.
