English Abstract




This invention relates to the construction of power plants of the type
described in the Canadian
patent no 2328580. Each of these plants is placed in a shallow pressurised
pool. A number of these
plants are connected together with the same pneumatic circuit, in order to use
the same flow of
compressed gas that enters in the first power plant and exits from the last
one of the same series
while producing growing energy with the same volume of gas that expends at
shallower depth and
displaces more liquid for a bigger buoyant force. These pressurized pools when
connected together
they give conditions of deep depths that permits the transformation of almost
all of the potential
energy of compressed gases at any pressure. In addition, these pools can be
built on the surface, or in
recycled ships where the transformation of compressed air produced by
compressors, using the
abundant and renewable energy of the sea waves is possible.

Hydroelectric power plant.

This invention relates to the construction of a series of power plants
according to the methods of the
Canadian patent no 2328580 into shallow pressurized pools, built on the
surface or in recycled ships.
The subject of this invention is the construction of a number of power plants
according to the
methods of the Canadian patent no 2328580 into shallow pressurized pools that
are connected
together with the same pneumatic circuit in order to use the same flow of
compressed gas that enters
in the first power plant and exits from the last one of the same series while
producing growing
energy. These pressurized pools when connected together they give conditions
of deep depths that
permit the transformation of almost all of the potential energy of compressed
gases at any pressure
into mechanical, electrical energy or else, and they can be built on the
surface or in recycled ships
where the transformation of compressed air produced by compressors using the
abundant and
renewable energy of the sea waves is possible. In addition, the low cost of
the construction of these
power plants into pressurized pools is another advantage of this invention.

The embodiment of this invention includes:

1- The construction of a number of power plants according to the methods of
the Canadian patent no
2328580, into shallow pressurized pools, and every one of these power plants
of the same series
includes:

A pool of liquid covered with a tight cover, except for the last power plant
of the same series which
does not need a cover, because that the air is dumped directly in the
atmosphere,

An upper driving cogwheel wheel placed just below the surface of the pool,
rotating in two ball
bearing housings attached to the walls of the pool so as to allow the output
shaft to pass through the
walls without leakage,

A lower cogwheel placed in the bottom of the pool rotating in two multi-
purpose ball bearings to
facilitate rotation and eliminate axial movements. The ball bearing housings
are fastened to the
1


CA 02460452 2005-01-26

frame of a tensioning device that allows adjustment of the tension of the
endless chain. The chain is
composed of special links that loop around the upper and lower cogwheels,
thereby rotating them.
The inner surface of the chain link conforms exactly to the outer surface of
the lower cogwheel, thus
ensuring a good seal between each chain link and the lower cogwheel.
Compressed air from the
main tank is forced without leakage into containers as they loop around the
lower cogwheel from the
lower horizontal to the ascending vertical positions. The rotation of the
power plant can be either
clockwise or counter clockwise.

Cylindrical containers are fastened to the chain links. Each container has a
half cover designed to
enhance the buoyant cycle by allowing the compressed air to be injected into
it as soon as it comes
into the horizontal position on the lower cogwheel. The half cover prevents
loss of air until the
container advances to an inclined position. Because the injection hole is near
the opening of the
container, a deflector is used to divert the compressed air toward the closed
end of the container to
prevent spilling. The air stops flowing into the container just before it
begins its ascent toward the
upper cogwheel pushed by the buoyant force of the liquid's potential energy. A
bevelled opening
under the half cover of each container and a protrusion on the exterior of the
closed end of the
following container fit snugly together. Any rattling due to hard contact
between the two containers
is eliminated by means of a rubber seal around the protrusion. Several holes
near the opening of each
container allow liquid to flow out of the container as the compressed air
expands gradually during
the container's ascent toward the surface. By the time it reaches the upper
cogwheel, the container is
full of air. The expanding volume of compressed air in each ascending
container displaces an equal
volume of liquid. The increasing weight of displaced liquid is the cause of
the growing buoyancy.
Force is equal to the weight of the liquid displaced by the compressed air.

A guiding device fastened to the wall of the pool ensures that the endless
chain and its containers
travel smoothly in a straight line without whipping or vibrations. The guiding
device is essential for
the proper functioning of the power plant and, if needed, can also be
installed on the descending side
of the chain on which the containers are full of liquid.

After the container arrives on the upper cogwheel, it inclines, emptying its
air as it passes over the
cogwheel. Simultaneously, liquid floods the container by gravity until it
reaches the descending
2


CA 02460452 2005-01-26

vertical position, at which point it's opening is facing directly upward. As
the container begins its
descent toward the lower cogwheel, it is full of water.

The endless chain provides continuous output to the drive shaft attached to
the upper cogwheel as
long as the correct quantity of compressed air is injected into each ascending
container.

A flywheel attached to the drive shaft ensures that the power plant has
continuous and uniform
rotation.

A Foucault current electromagnetic brake combined with a gearbox regulates the
rotation speed as
required for the electrical generator or any other device to be driven by the
power plant.

A lubricating system lubricates moving parts as required.

The compressed air injected into the containers with thrust comes from a main
tank supplied by one
or more of the following:

a) Taylor hydraulic air compressors, popular in the mining industry until
approximately 1981:
U.S. Patent Nos. 543410, 543311, 543312, 618243, and 892772;

b) Ocean wave air compressors: Canadian Patent No. 541393;
c) Conventional air compressors,

d) Instead of using compressed air from the sources described above, gas
produced geo-
thermally from black smokers in the sea bottom or elsewhere can be collected
using cones and
pipes, then transferred to the main tank of the power plant.

Alternately, the excess pressure of natural gas can be used. In this case, the
pool must be covered to
avoid leaks. After exiting the containers, the natural gas proceeds normally
at an agreed-upon lower
pressure.

3


CA 02460452 2005-01-26

If required, a secondary air compressor powered by combustion engines or by
other means can be
used to start the power plant, possibly assisted by a starter.

The total buoyant force of all the containers with thrust determines the
overall capacity of the power
plant. This is equal to the weight of the liquid displaced by the total volume
of air in the containers
with thrust expressed in Newton, multiplied by the distance between the centre
of the drive shaft and
the centre of gravity of each container. This distance is the sum of the
radius of the upper cogwheel
and the radius of the container expressed in meters, multiplied by 2,
multiplied by (pi or 3.1416),
multiplied by the number of revolutions per minute (rpm) of the power plant.
The result of the
foregoing multiplication will be divided by 60 seconds to express the power in
watts, and by 746 to
express this value in horsepower, (each unit of horsepower being equal to
approximately 746 watts).
Power = Force (Newton) x (Radius of wheel + Radius of container) meters x 2 x
pi x rpm. / (Divided
by) (60 sec. x 746 watts) = horse powers

2- all of the power plants of the same series are connected together with the
same pneumatic circuit,
in order to work with the same compressed gas flow according to the following:

A- the first of the power plants of the same series that are in pressurized
pools receives the highly
compressed gas in its ascending containers through its rotary transfer joint
as explained in the
Canadian patent no 2328580. The volume of the gas inside its ascending
containers is affected by
the hydrostatic pressure according to the depth of each container, added to
the pressure that exerts on
the surface of the pool, which is equal to the hydrostatic pressure of all the
column of water in all of
the following pools of the power plants of the same series, added to the
atmospheric pressure. When
the ascending containers of this first power plant exhaust their compressed
gas at the surface of the
first pressurized pool, the actual pressure of the gas becomes the equivalent
of its pressure when it
was initially injected in the ascending containers at the bottom of its pool
minus the hydrostatic
pressure of the column of water of the same first pool.

Note: The volume of the containers of every power plant of the same series has
to be well calculated
in order to contain all of the expended volume of the gas due to lower
hydrostatic pressure at
shallower depth.

4


CA 02460452 2005-01-26

According to Boyle's law, the relation between the volumes and the pressures
in this first power
plant is as follow:

P 1 x V l= P2 x V2 = Constant
Where

P 1=(hydrostatic pressure at the first position of the container in the first
pool at height (H 1) +
Pressure that exerts on the surface of the first pool under its tight cover
that is equal to:
[Atmospheric pressure + (total hydrostatic pressure of the column of water of
each pool x the
remaining number of pools of the same series)].

P2 = (hydrostatic pressure at the second position of the container in the
first pool at height (H2) +
the pressure that exerts on the surface of the first pool under its tight
cover that equals to:
[Atmospheric pressure + (total hydrostatic pressure of the column of water of
each pool x the
remaining number of pools of the same series)].

V 1= the volume at height (H 1).

V2 = the new volume at height (H2)

B- Coming from the first power plant the same gas enters in the ascending
containers of the second
power plant of the same series through its rotary transfer joint at the
pressure that is registered under
the tight cover of the first pool.
At the surface of the pool of this second power plant, the pressure of the gas
diminishes again the
equivalent of the hydrostatic pressure of the column of water of the second
pool. Another time the
compressed gas continues its way by entering the third power plant through its
own rotary transfer
joint.

According to Boyle's law, the relation between the volumes and the pressures
in this second power
plant is as follow:



CA 02460452 2005-01-26
P 1 x V l= P2 x V2 = Constant

P 1=(hydrostatic pressure at the first position of the container in the second
pool at height (H 1) +
Pressure that exerts on the surface of the second pool under its tight cover
that equals to:
[Atmospheric pressure + (total hydrostatic of the column of water of each pool
x the remaining
number of pools of the same series)].

P2 = (hydrostatic pressure at the second position of the container in the
second pool at height (H2) +
the pressure that exerts on the surface of the second pool under its tight
cover that is equal to:
[Atmospheric pressure + (total hydrostatic of the column of water of each pool
x the remaining
number of pools of the same series)].

V 1= the volume at height (H 1).

V2 = the new volume at height (H2)

C- we continue the same way according to the number of power plant with
pressurized pools until
the last one.

If the series of these power plants taken as an example transforms the
potential energy of natural gas,
the last power plant will have a tight cover too like the previous ones, in
order to collect the natural
gas after it exits the ascending containers at a pre-determined pressure to be
able to send it back in
the local pipeline.
And if compressed air is used instead of natural gas, the last power plant
will not have a tight cover
like the previous ounces because the air will be dumped directly in the
atmosphere.

3- The recycling of old ships into hydroelectric power plants, where the
abundant and renewable
energy of the sea waves can be exploited to produce the needed compressed air
to run these power
plants in order to provide electrical power to cities and other locations at
medium or low voltage,
that lowers the cost of every kWh produced.

6


CA 02460452 2005-01-26

In summary, the main advantage of this invention is:

1- To be able to transform almost all of the potential energy of compressed
gases into mechanical
then electrical or other form of energy, inside economical hydroelectric power
plants functioning in
series with the same pneumatic circuit that connects all of the above
mentioned power plants, in
order to allow the same flow of compressed gas, to run them all, while
crossing from one power
plant to the next, until it exhausts from the last one, and producing growing
energy because of the
volume of the compressed gas that expands at shallower depth due to low
hydrostatic pressure,
according to the position of each ascending container, where the buoyant force
in every one of these
power plants is equal to the weight of the water displaced by the volume of
the compressed gas, that
is in all of the ascending containers of each power plant.

Depending on site specifications and the output required various components;
configurations and
dimensions for the embodiment may be combined to achieve the desired results.
For a better
understanding of this invention and to facilitate its examination, it is
represented in the following 13

situation where the compressed air pressure is low, and a low hydrostatic
pressure is needed.

When considered with the description herein, the characteristics of the
invention are apparent from
the accompanying drawings, which exemplify an embodiment of the invention for
purposes of
illustration only, and in which -

In figure 1 the compressed gas enters into the ascending containers of the
power plant A through the
air tank 22, the gas lines 21-A and the rotary transfer joint 18-A-A, in order
to transform a part of its
potential energy according to the described method in the Canadian patent no
2328580. The
ascending containers of the power plant A exhaust their gas A-2 under pressure
A-4 shown in the
pressure gauge 26-A on the surface A-1 of the pool 1-A under the tight cover A-
3. Then the same
gas A-2 that has already lost of its pressure the equivalent of the
hydrostatic pressure of the column
of water of the pool 1-A of the first power plant A, continuous its run and
enters in the power plant
B of figure 2 through the gas line A-7.

In figure 2 the compressed gas enters into the ascending containers of the
power plant B through the
air line A-7, the gas lines 21-B and the rotary transfer joint 18-A-B, in
order to transform another
part of its potential energy according to the same described method in the
Canadian patent no
2328580, but the quantity of energy that is produced in power plant B is
bigger then the quantity of
energy produced in power plant A, because the expended volume of gas has
displaced a bigger
volume of liquid in power plant B where the buoyant force is equal to the
weight of liquid displaced.
The ascending containers of the power plant B exhaust their gas B-2 under
pressure B-4 shown in
the pressure gauge 26-B on the surface B-1 of the pool 1-B under the tight
cover B-3. Then the same
gas B-2 that has already lost of its pressure another time the equivalent of
the hydrostatic pressure of
the column of water of the pool 1-B of the second power plant B, continuous
its run and enters in the
power plant C of figure 3 through the gas line B-7.

In figure 3, the compressed gas enters into the ascending containers of the
power plant C through the
air line B-7, the gas lines 21-C and the rotary transfer joint 18-A-C, in
order to transform another
part of its potential energy according to the same described method in the
Canadian patent no

CA 02460452 2005-01-26

2328580, but the quantity of energy that is produced in power plant C is
bigger then the quantity of
energy produced in power plant B, because the expended volume of gas has
displaced a bigger
volume of liquid in power plant C where the buoyant force is equal to the
weight of liquid displaced.
The ascending containers of the power plant C exhaust their gas C-2 under
pressure C-4 shown in
the pressure gauge 26-C on the surface C-1 of the pool 1-C under the tight
cover C-3. Then the same
gas C-2 that has already lost of its pressure another time the equivalent of
the hydrostatic pressure of
the column of water of the pool 1-C of the third power plant C, continuous its
run and enters in the
power plant D of figure 4 through the gas line C-7, if the series of the power
plants A, B, C, and D is
used to transform the potential energy of natural gas under high pressure, or
it enters in the power
plant E of figure 5 through the gas line C-7, if the series of the power
plants A, B, C, and E is used
to transform the potential energy of a highly compressed air.

In figure 4 the compressed natural gas enters into the ascending containers of
the power plant D
through the gas line C-7, the gas lines 21-D and the rotary transfer joint 18-
A-D, in order to
transform another part of its potential energy according to the same described
method in the
Canadian patent no 2328580, but the quantity of energy that is produced in
power plant D is bigger
then the quantity of energy produced in power plant C, because the expended
volume of gas has
displaced a bigger volume of liquid in power plant D where the buoyant force
is equal to the weight
of liquid displaced. The ascending containers of the power plant D exhaust
their gas D-2 under
pressure D-4 shown in the pressure gauge 26-D on the surface D-1 of the pool 1-
D under the tight
cover D-3. Then the same gas D-2 that has already lost of its pressure another
time the equivalent of
the hydrostatic pressure of the column of water of the pool 1-D of the fourth
power plant D,
continuous its run and enters into the pipeline D-7 of figure 4 through the
gas line D-5 and the check
valve D-6.

In figure 5 the compressed air enters into the ascending containers of the
power plant E through the
air line C-7, the gas lines 21 -E and the rotary transfer joint 18-A-E, in
order to transform another
part of its potential energy according to the same described method in the
Canadian patent no
2328580, but the quantity of energy that is produced in power plant E is
bigger then the quantity of
energy produced in power plant C, because the expended volume of gas has
displaced a bigger
volume of liquid in power plant E where the buoyant force is equal to the
weight of liquid displaced.


CA 02460452 2005-01-26

The ascending containers of the power plant E dump their air E-2 in the
atmosphere, it means at the
atmospheric pressure E-3.

Figure 6 shows how the power plants A, B, C and D function with the same flow
of natural gas
under high pressure. The natural gas enters into the rotary transfer joint 18-
A-A of the power plant
A, through the lines 21-A coming from the gas tank 22, then into the rotary
transfer joint 18-A-B of
the power plant B, through the gas lines 21-B coming from power plant A
through the gas line A-7,
then into the rotary transfer joint 18-A-C of the power plant C, through the
gas lines 21-C coming
from power plant B through the gas line B-7, then into the rotary transfer
joint 18-A-D of the power
plant D, through the lines 21-D coming from power plant C through the gas line
C-7, then finally
into the pipeline D-7 through the gas line D-5 and the check valve D-6.

Figure 7 shows how the power plants A, B, C and E function with the same flow
of highly
compressed air. The compressed air enters into the rotary transfer joint 18-A-
A of the power plant A,
through the air lines 21-A coming from the air tank 22, then into the rotary
transfer joint 18-A-B of
the power plant B, through the air lines 21-B coming from power plant A
through the air line A-7,
then into the rotary transfer joint 18-A-C of the power plant C, through the
air lines 21-C coming
from power plant B through the air line B-7, then into the rotary transfer
joint 18-A-E of the power
plant E, through the air lines 21-D coming from power plant C through the air
line C-7, then finally
the free air is dumped in the atmosphere.

Figure 8 shows a ship 103 transformed into hydroelectric power plant that is
connected to the main
grid through the transformer 102 and the distribution lines 101.

Figure 9 shows a ship 103 parked on the sea shore 114 including the air tanks
105, the air line 21
that transits the compressed air to the rotary transfer joints 18-A, the pool
111 of the power plants,
the endless chain 37, the cogwheels 35 and 35-A, the containers 19, the water
reservoir 110 where
the water of the pool 111 drops in by gravity through the water valve 112 in
order to reduce the
water level in the said pool 111 when the height of the sea waves is less then
normal, to permit to the
power plant to continue running and producing energy. The water reservoir 109
that is used to rise
11


CA 02460452 2005-01-26

the level of the water of the pool 111 when the height of the waves is higher,
again to permit to the
power plant to transform more energy.

Figures 10 and 11 when they are put together side-by-side, figure 11 to the
right and figure 10 to the
left, they represent a module having 4 power plants A, B, C and E working in
series with the same
pneumatic circuit that supplies all 4 power plants with the same flow of
compressed air. The
compressed air is injected initially when it is under full flow pressure in
the ascending containers of
power plant A through its rotary transfer joint 18-A-A when they loop around
the lower cogwheel
according to the Canadian patent no 2328580. The compressed air volume in the
ascending
containers expends at shallower depth all during the ascending run until the
air is dumped on the
surface A-1 of power plant A. The buoyant force in power plant A is equal to
the weight of the water
displaced by the total volume of the expended air in all the ascending
containers of power plant A.
Under the tight cover A-3, and on the surface A-1 of the pool 1-A, the
compressed air A-2 is now
expended and its pressure A-4 has dropped the equivalent of the hydrostatic
pressure of the column
of water 125 of the pool 1-A. Then, the same expended air A-2 is forced to go
through line A-7 to
the ascending containers of power plant B through its own rotary transfer
joint 18-A-B. The same
thing happens in power plant B as in power plant A, where the compressed air
volume in the
ascending containers expends again at shallower depth all During the ascending
run until the air is
dumped on the surface B-1 of power plant B. The buoyant force in power plant B
is equal to the
weight of the water displaced by the total volume of the expended air in all
the ascending containers
of power plant B.

Under the tight cover B-3; the compressed air B-2 is now expended and its
pressure B-4 have
dropped the equivalent of the hydrostatic pressure of the column of water 125
of the pool 1- B. Then
the same expended air B-2 is forced again into the ascending containers of
power plant C through
the line B-7 and the rotary transfer joint 18-A-C. The same thing happens once
more to the
compressed air by expending another time at shallower depth. And ounce again
at the end of the
ascending run, the expended compressed air is dumped on the surface C-1 of the
pool 1-C of power
plant C. The buoyant force in power plant C is equal to the weight of the
water displaced by the total
volume of the expended air in all the ascending containers of power plant C.

Under the tight cover C-3, the compressed air C-2 is now expended and its
pressure C-4 has dropped
another time the equivalent of the hydrostatic pressure of the column of water
125 of the pool 1-C.
Then the same expended air C-2 is forced for the last time into the ascending
containers of power
plant E through the line C-7 and the rotary transfer joint 18-A-E. In this
last power plant of the same
series, the same thing happens to the compressed air by expending another time
at shallower depth.
And ounce more at the end of the ascending run the expended compressed air is
dumped on the
surface E-1 of the pool 1-E of power plant E into the atmosphere. The buoyant
force in power plant
E is equal to the weight of the water displaced by the total volume of the
expended air in all the
ascending containers of power plant E.

Figures 10 and 11 include power plant A, the pool 1-A, the depth 128 at the
opening of the bottom
vertical container 131 of the ascending containers (all the column of water
between the surface of
the pool and the opining of the bottom vertical containers of all power plants
of this examples have
the same depth), the rotary transfer joint 18-A-A, 8 ascending containers for
every power plant, with
equal length 126 and half length 127 (all the containers in this example have
the same dimensions),
the cover A-3, the pressure A-4 that is equal to the atmospheric pressure E-3
plus the hydrostatic
pressure of the all the column of water of power plants B, C and E, the depth
128 at the opening of
