Waves work in a constant up-and-down movement, back and forth, and the WaveReaper, a simple mechanical device, takes advantage of this in a cheap way. As we said, the wave moves up and down, while most generators, rotate around an axle, and the wave size varies a lot, and creating problems, when you want to utilize their energy content. The current technologies regarding wave energy today is very costly, which means they can't compete with other ways of making energy. The technology can also be used to save the shoreline from The North Sea, Causing havoc in northern of Europe in Great Britain.
Onshore WaveReaper
This is a simple schematic, showing buoy, wire and one-way bearing, connected together. In case of storm and rough waves, it is a problem, for all wave energy constructions, however, the Wavereaper™, has a built in safety feature in its construction, that would avoid damage on the equipment, its due to the max lifting force of the barrels, since they will sink under the surface, if the force is to great. this will make the Wavereaper possible to work in any weather, however it should be constructed, to take advantage, of the medium wave, that is present at all time, for best cost benefit of the plant.
Another factor, water, and generators, yes, almost any technology, is having problem, when it comes to the oceans salty water without more expensive design and material. Water can leak inside equipment and ruin electrical circuits, and it must therefore be safeguarded against corrosion, and in those cases it is under water, against leakage, corrosion and pressure. Also water-depth, and the special environment, which crave divers, and other expensive equipment, has made wave energy very costly.
With other words, underwater technology is not cheap, and with these problems to solve, which means high costs, and therefore more expensive energy for the consumer. This is not what we would like, so it is need to solve the wave energy generation concept, to go around these problems. And the solution is simple, we can use basic items, as wire, plastic barrels, one way bearings, pulley, an axle, flywheel and generator.
That is the main components, in what up to day, would be the cheapest wave energy technology in the world. It can even be built in wood or by choice bicycle parts! This is very good, in countries which have limited access to expensive metals, and heavy machining tools. Most of the parts in a WaveReaper generator, except wiring, can be made of wood, plastics or more expensive metal.
WaveReaper plastic barrels in the waves.
We will use a set of plastic barrels as boys, cost is low, and PVC isn't affected by salty ocean water. The barrels are placed near shore or longer out in deeper water, depending on amount of energy needed in particular wave plant. The Barrels will also help for erosion problems in shoreline. For example in England.
Power transmitting wires, and aluminium pipes controlling the blocks.
To avoid the need for divers, and also avoid the need to have boats when the WaveReaper is deployed an special aluminium pipe is used. The pipe is mounted in sections, and prolonged further out in the sea. I think it is possible to have distances up to 300 meters from the shoreline, to get access to greaters dephts, where also the waves is greater. Lifting containers have to provide lifting force to the pipe, and right under every barrel wich is producing power to the onshore WaveReaper generator, a round plate is placed, this plate will prohibit the lifting force the rising barrel will have on the pipe,
The pipe remains steady approx 5 meters under the water. This design will ensure that the operation of the WaceReaper plant can be done from the shoreline only, without need for divers, and without need for boats, wich is normally used when it comes to wave power generation.
This is bringing down service cost, and also the level of education needed to run the plant is lesser, when noone have to dive. Diving is a very costly part of operation of a wave generator. If something happens with the blocks wires or barrels, the pipe can easy be hauled onto shore, and repaired or replaced.
The barrels is on 2 meters distance from each other, and connected to the on mainland placed WaveReaper generator, via the “power transmitting wire” it is also is connected with a thinner wire, between them, so, if the power wire should break, the barrels, don’t get to drift away, in the sea. This will also even out the possibility that the barrels, would smash into each other, when the sea is rougher.
The Aluminium pipe can be burried in gravel and sand for inexpensive building.
The lifting capacity is also setting a maximum power input into the device, since if it is large and fast waves, the barrels would not lift more than it can, and forces is kept within its chosen range, chosen when constructing the WaveReaper plant.
Power out put of waves kW per meter of WaveReaper, approximated 30% energy after conversion.
I have chosen to use cheap materials only, in this demonstration, because the need to bring down production costs, and make it possible to build this type of wave generation device, any where in the world, and with local materials, as car parts etc, which doesn't needs to be imported. Other materials could of course be used, and the schematics for its design of course, be different. Simple is better, it is said, and fewer parts, and bearings, will bring lower cost of building, and also repair.
Front Scematics WaveReaper
The wire is connected to a chain in the end, witch works on a gearwheel sitting on a one-way bearing, mounted on an axle. This translates the pulling force of the wire, to an circular movement which is good for cheap generators. The wire is for this case 4 mm stainless steel, which give a lifting ability of approx 300 Kg before it brakes. Also plastic can be used as the Pvc band, which today is commonly used for packaging goods on pallets, this type of PVC band has high strength, and is also light, and cost-effective, of course the UV light from the sun is affecting it in the long run, but the part that is in the water, should be somewhat guarded from the UV rays.
Flywheels is also mounted on the axle, to collect, even out and store the momentum which is produced by the lifting barrel, this will even out and, smooth the turning's of the axle, to the generator, which is driven by a pulley, who will give it correct rpm. A simple brake, which can never wear down, is also planned, in those cases, constant current generators, or a special electronics device is not used.
Profile Scematics WaveReaper
When the wire is coming up to the generator housing, a chain is mounted to the wire, which drive the Gear wheel, and the one way bearing, which makes the chain draw, when the waves raises the barrel, but let it spin freely back, when the wave height is going down again, also a small weight is connected to the chain, to make it even out slack of the wire. A flywheel is mounted, and a pulley drives the generator, evenly.
Suggested Prototype Design
One-way bearing, with pulley and wire, and with bigger loads, chain and gearwheel, is an option. One-way bearings can be seen in ex. bicycles, the rotate freely in one direction, but in the other direction, they grip, and transfer force, this is used in the Wave reaper, and makes it simple, and cost effective. The waves up and down, movement is translated to rotating movement, suited for a generator, of choice.
Suggested Prototype Design
The Benefits of the One-way bearing.
The barrels will of course jump up and down in random patterns; this will add to an even movement of the generator axle, and its flywheel, as soon as a wave has energy to contribute, it will transmit its force to the wire, and to the axle. The flywheel is storing the momentum gained from the waves temporarily.
Because of its design, the WaveReaper, is always self adjusting regarding wave height, and tidal shifts, and higher or lower water levels due to shifting weather patterns, no adjustment needed, the Wavereaper™ is always balancing itself out, to optimal level in the ocean.
500 Kilowatt to 1 Megawatt Plant
Example: number of barrels in each row 10, and rows 10, the plant would be 20 x 20 meters of area, 400m2, and will have 100 connected wires, which transfer the mechanical energy, to the generator. This type of plants, give 100 to 500 kW every hour, which generates profits, of 6500 to 25 000 dollars of revenue monthly, building cost of the plant is estimated to 20 000 dollars only. This will give that the WaveReaper earns itself, in a few months, instead of many many years!
No complicated technology is needed, which would need delicate conditions, or a lot of service. This technology, offered globally for free, Anyone can now build his very own, generator.
Let everyone know, friend and foe, its time for things to change in the worlds energy sector. Oil based economy, is not needed anymore, lets all accept it, and build a better world, lets feed the hungry, cure the sick, and of course, stop polluting the environment, with the oil based stone age technology.
