Description of the Wave Rocker - Technical version -
There are a few types of wave energy machines in the market that use the water rushing in and out of a tube to move the air mass in it. This normally drives a Wells turbine, Air this is the poor relation in the energy business, a good example of this is all the abandoned wind farms in California The other is flotation in various forms using water on a Wells turbine or pumping serpents etc.
When you look at
the waves, you may think they are coming in. They are not coming in as such
though, it is the effect of the renewable energy passing through the mass of
water that in itself is just moving more or less up and down and back and forth
in a circle. What moves the water mass are the tides and sea currents, what
you see on the shore is the same water, moving at the speed of the tide and
currents with the renewable energy passing through the water making the waves.
This energy comes from the winds caused by the sun.
The accumulated power the wind drag has built up over the distance it has travelled
to get to the shore is released in the braking waves. That's why there are big
waves in the Pacific Ocean and short steep waves in the Mediterranean and very
little ones on an outside boating lake. Distance and wind speed drag on the
surface make the wave size, the angle of the shore where it comes in gives the
final result.
The pitch is the distance between the waves, which makes the basic wave pattern.
A craft will change its angle going up the front of an approaching wave until
it gets to the crest. The normal angle of the wave face is between 10º
at 2 m/s and 30º at 10 m/s. That's a good blow if you are a sailor. It
can be steeper near the shore just before it breaks.
When the craft
is making the effort of going up the wave face, its weight and the drag force
it back down the sloping face by the energy force contained in the wave. Once
the craft is at the top, which is more or less the neutral position from all
the forces of the wave that wanted to take it with it, now being liberated from
these forces it speeds up as it surfs down the other side. This can be exhilarating
or very frightening in a small sailboat in a big sea or a bigger faster boat
in an even bigger sea. Like some folks say when we are very happy and enjoying
the ride: "They are riding on the crest of a wave".
If we anchored a craft or any floating object, it would want to go backwards
as it fights its way up to the crest of the oncoming energy force in the wave.
As its centre of gravity changes it becomes level at the top. Going up the wave,
the centre of gravity moves aft making it "drag its ass "as they say.
Which puts up the resistance on the anchor and tackle. Using an elastromeric
mooring system the drag effect can be changed to give a better and more useful
result.
From the sum of these forces, acting on the hull of the craft, Renewable Energy
(RE) can be collected and stored up in an elastromeric mooring system. This
is like when you use your muscle energy to pull back the rubber on a catapult
or a stretched elastic band to ping across the office.
After the craft has fought this energy that was trying to push it back (as much
as 70 kW per m³ average), it then reaches the crest and starts to go down
the backside of the wave . The centre of gravity moves forwards, helping to
accelerate the craft, and with the help of the collected energy stored in mooring,
the elastromeric effect is released. I.e. "The chain sinks or the nylon
rope recovers" in normal moorings. Then the craft starts to move faster
down to the trough of the wave pattern, recovering this collected energy in
inertia speed, only to be stopped by the wall of water of the next oncoming
wave.
This effect can be amplified by adding vortex drag foils or a special shape
to the hulls in the negative aft position. To increase the drag factor that
can help the collection of this Renewable Energy (RE), a special type elastromeric
mooring system is used. When this drag energy is released, the extra speed has
an effect on the craft ~ Like a truck slamming into a concrete wall or your
body on the safety belt when you have to do a emergency stop. Lots and lots
of energy that has to go somewhere or be absorbed. This RE can be used in our
new revolutionary 4p-wave machine to make a cleaner better world.
For the most beautiful thing about Renewable Energy is, it does not pollute, spoiling our world and mankind's chance of survival. It makes the poor inhabitant of this planet independent of all the powers that wish to be in control and are destroying it with the polluting forms of energy that are having such a devastating effect on our one and only planet and all the life Mother Nature has put on it. And being renewable, it is endless; it will be there and available as long as our world turns.
As the old saying goes: "Money is the root of all evil". Maybe! And perhaps that's why it's so difficult to raise money to invent, research, develop and build machines in this sector for concerned and capable individuals or small organizations like our charity that work in this field.
How foolish is the greed of the happy few in power! It's their families as well that will suffer alongside all of us, because these poor little rich people mistake their greed for love and understanding for their loved ones and our world. Just this makes our planet collapse, which it will do soon, if we do not change our ways. It is already showing major signs off what is to come! Just look at the world news each day if you doubt my words. In the news headlines every day we see a little of what is happening, and that is just a fraction of what others see and know about. Others who are not so lucky to live where we do, really do have to suffer because of the effects of this ignorance and greed etc etc.
But this article is not about the moral behaviour of our elite few or the ignorant mass that are brain washed by them. So, dear reader, let's go back to the core.
All you have to think about is a wagon with wheels connected to a reciprocating pump. The wagon going up and down the length of the flat deck of a catamaran boat making the pump work, the piston rod connected to the wagon and the cylinder end connected to the bows.
You should now know all the forces, which are going to be combined to make a clean, cheap, very powerful Renewable Energy machine. Like you can only make a good meal with common sense and a little bit of love, if you want your love ones to stay fit and well.
We all should know the effect of cargo or something like a large truck, loose in a ship's hull and the damage it can do, acting like a battering ram that can punch a hole in the ship hull, capsizing it or sinking it. And we should know what the slosh effect is, which in addition could be used to amplify the tilt angles of the craft, just as water ballast trim tanks can be added and used to adjust the sensibility to suit the wave conditions and output RE wanted.
We also all know what is a child's rocking horse or granny's favourite rocking chair and how they move, but do you really know why? Well, they normally have two curved rockers touching the floor. So if we have the hulls of a catamaran made so that they make the same effect on the water, there is never a time it stops moving. Because the rider or granny or the waves passing underneath the craft, are always changing the centre gravity. So all the free weight can change its position as well, that's why to date, with our simple shoestring R&D, we think a Catamaran type hull the most suitable for this job ~~~~All rock and no roll~~~~
As the craft (cat) goes upwards on the oncoming wave, that wants to take it with it, the centre of its balance moves towards the stern, making it dig in its backside to resist. This puts a drag force on the hull that is connected to an elastromeric mooring, thus stretching it like it is loading a catapult. Now if there were a weighted wagon on the deck, it would also want to move backwards down the slope of the deck from the lifting pitch moment as the bow comes up. Just like a car rolling backwards on a hill. To stop the wagon going overboard it is connect to the piston rod of the pump, so with this backward movement it sucks in its input charge. (Or a limit stops for direct linear electrical generation and safety). This working fluid charge helps to start to balance the craft as the cylinder end of the pump is connected to the bow fills. When the cat gets to the crest of the wave the charging is finished. It then starts to go down the other side of the wave, and the weighted wagon wants to move up to the other end where the charge already is, because the centre of gravity is changing. Just like that car on a hill needs no engine to go down the hill. The wagon starts to push out its working charge as it moves towards the bow. Also something else has to move with all this renewable energy that has been collected. The effect of the wagon going forwards levels and speeds up the cat as it goes down the backside of the wave. Helped by all the other collected energy that is being discharged from the elastic mooring system, which is now getting back to its unstressed position, as there is no drag load. When the cat reaches the trough between of the wave pattern, it then wants to dig in its bows. Because most of the weight is now at the wrong end to go up the coming wave, the digging of the bows into the oncoming wave will stop the speeding cat. The weighted wagon, which is still free to move in forward direction with the inertia forces acting on it, move the rod and the piston that is pushing into cylinder, giving the final compression force on the rest of the working fluid charge to empty the cylinder. Or make a super charge surge of linear renewable electrical energy (LREE.)
The renewable energy output then can be used to do many useful things. Like driving a hydraulic motor connected to a generator to make electricity, pump seawater out of dykes, or make fresh water from the sea through a reverse osmosis system powered by the waves, while at the same time this fresh water made on board can all be piped from the craft to where it's needed by this real positive power the catamaran is floating in. Different pumping and linear generation systems etc. can be in the hulls and on numerous decks in the craft if required. The practical size of the craft would be to suit the sea site, where it was stationed.
In the oceans the distance between wave crest is about 80 /100 Mts. So a craft of 30/50 Mts. long could be used with very heavy wagons weight moving the pumps etc. Being a craft it self adjusts to the water level and can be moved to where you need it. This makes it also ideal for emergency use. Besides, it can easily be serviced by taking it back to port or out of the waves in the lee.
This new renewable
energy principle and type of machine, which is now working in experimental forms,
when fully developed, will give us all a little more hope! Hope for a cleaner
and more efficient world. It is probably the most effective way to use, the
positive energy of blowing wind anywhere it makes a wave.
