Principle of Operation

• Our wave device is few rotors with work cells which are located on their side surface (rotor by Winkrants). Rotors are gathered parallel by hard frame and are connected with conventional electrical generator through transmission.
• Work cells are equipped with valves, which let pass water and air in one direction- only inside work cells. Thus, while sea water is oscillating and is passing inside work cells on one side but is not passing on another side, inequality of gravity pull and Archimede's force is existing. Therefore, rotating moment is appearing.

The pilot wave power device of full size (5x10 m) with capacity up to 3 kW will be assembled and installed at seashore in Ha'apai Islands in Tonga under the Project. This power unit will be used for autonomous energy supply of FM transmitter with power about 1 kW.

Float parts of the device are made from recycled plastic: work cells from HDPE and work rotors from PVC. After assembling the device will be toweled and moored in the deep water on the concrete anchors. The device is connected to consumer of electricity by underwater cable. There is accumulator battery for non-stop energy supply despite on whether conditions.

Who wasn't standing at the seashore watching how roaring energy of waves was spending uselessly?

POSSIBILITIES

How much energy do sea waves bring? Physics show, that wave energy increases in proportion to third power of amplitude. Therefore, each 10 meter-wave brings 150 kW per 1 meter of wave front. Then 1000 meters power plant can give 15 MW even having 10% co-efficiency. This would be enough for 30 thousand inhabitants of a small town.

Winter energy consumption of Great Britain (30 GW) can be satisfied by wave power plant situated in North Atlantic behind Hebrides. Those huge waves are able to move ranges of big power plants - 1000-2000 meters length and 150-200 MW power.

Small consumers can be supplied with little units - 10-20 meters length and 10-20 kW power.

Fancy that you can feed your TV set, iron, and chandelier at your cottage from 1 meter of wave running into seashore. It's true, since the 3 meter-wave brings about 10 kW of mechanical energy per 1 m, which can be transformed into electricity. But how you can do that? This matter has its own history, problems, achievements, prospects and tree of the product.

HISTORY

The first patent on wave energy usage was filed about 400 years ago in France. This device was just a barge connected by a long lever with the pump for water. This device was built never because of technical difficulties.

Interest in renewable sources of energy was revived after first serious oil crisis - about 30 years ago. Then more advanced schemes were developed:

"Column" by Mr. Masuda.

Navy officer in Japan Masuda offered floating can, opened below. Air column inside this can, being swung by waves, are directed into air turbine generator through valves. The "Column" by Mr. Masuda is only wave device, which is produced in small series and is used for energy supply of navigation buoys. Such buoy-generator have power about 30 W and auto lead battery as an accumulator. Service life of such device is about 3 years and is limited by corrosion and service life of lead battery. But idea to supply cities with "big energy" bore huge Masuda's "Column" - "Kimay" project in 1979. "Kimay" device looked like a big ship - 280 meters length and 30 meters wide, it cost 80 million yens, was made of concrete and had electrical power 1800 kW. After "Kimay" project Japanese government had to make decision to finance full-scale project of construction of 1500 MW power plant. But money wasn't gotten.

Last time professor Wells with Californian Wevegen Company developed air turbine, which doesn't need valves. This turbine works in bi-directed air current and is named "reversive turbine".

The biggest project with "reversive air turbines" started in Scotland Hebrides Islands. A cost of the project advances about 380 thousand of pound. This energy plant will supply the island settlement with 1000 kW.

"Duck" by Mr. Salter.

Professor Salter with Edinburgh University invented "Duck" in 1973. Then the first big oil crisis blew about Europe and that made scientists to think about source of energy, which will be eternally - sea.

Mathematic calculation allowed creating the device, which absorbs 90% of wave energy. The special basin equipped measure apparatus was built for test of models. Models in 1/150 scale showed excellent results and moved that full-scale power plant should be built immediately. It must be a chain of concrete "ducks" 1500 meters by length and 30 million pounds by cost. But bureaucracy buried the project.

"Raft" by Mr. Cockerel.

Another successful instance of private initiative in wave energy matter is "Raft". It was developed and tested by "Hovercraft" Company. Mr. Cockerel, the creator of hovercraft, spent his own money and constructed 1 kW "Raft". This "Raft" has 3 floats connected to each other with hinges. They have levers, moving hydro pumps. Water from hydro pumps moves hydro engine connected with electrical generator. Such 1 kW "Raft" was working in the bay near Southampton for few years. But officials with Ministry of Energy didn't put any attention for this extra effort.

"Box" by Mr. Russell.

The only type of wave power device, which started to build in industrial scale, is "Box" or "Shutter". Mr. Russell with National Hydrological Institute (GB) developed this device. It is just a concrete box or basin with valves in its front wall. While sea waves lapping against the front wall, water is poring through valves and is increasing water level inside a basin. Then water flows out through the hole with turbine in the back wall and products electrical current.

Such scheme seems to be most simple. That's why based on this principle a power plant with 5 MW capacity started to build in Mauritius in spite of its high cost. They had to use laguna along the shore as a basin and had to use reef as a base for the front wall. The construction was led under Britain Ministry of Energy direction but suddenly oil price became lower. The construction was frozen.

So, we can see that any wave power plant hadn't been built in spite of its obviously ecological adventures. The people begin to think about renewable sources of energy facing a new fuel crisis only. Humanity thinks about clear energy being threatened by poisonous air and water, when resources for creation of renewable energy system are exhausted.

PROBLEMS

Since definite density of wave energy is between 1-100 kW per each meter of wave front, we have to use appropriate area of sea surface to get necessary amount of energy. In case 100 kW- 100 MW consumption such area can be about 2000-30000 m2. Being built of concrete or steel such energy plant can cost $500.000,00 - $5000.000.000,00. This cost is on the level of heat or nuclear power plants; therefore it is usual for power plants.

Although wave power plant doesn't use any fuel, the money for it's building wasn't gotten in any country. The second big problem of wave devices is their stability under action of huge waves. Measures against devastation by sea waves are quite expensive. That's why floating wave devices are reliable and preferable for wild-scale introducing.

ACHIEVEMENTS

The best material for wave unit production in industrial scale is plastic (polyethylene, polypropylene and so on). Such material isn't expensive, especially recycled - about $100 per 1 ton. There are a lot of machines for blowing and extrusion of different kinds of details for wave device. Then self-cost of small plastic wave power plant will be $150-160 per 1 kW, and of large one even less. Service life of plastic wave devices is 3-5 years and depends on sun radiation resistance. Since pay back term of power plant is 3-4 months, its self-cost will return 12-15 times. It's not too bad for energy sector of industry.

SEG (Sea Electrical Generators) Company developed and tested few types of floating wave power plants with different capacity. These wave power plants don't need any exploitation service, are reliable, easy and don't corrode, can be used anywhere there are waves. Production of such wave power units can be arranged at the seashore anywhere. Plastic hollow elements are blown by special automatic machine at the plant are transported to the place of usage at the seashore and are assembled into whole unite very easy. Conventional electrical generator with required power is connected with the unit. Then ready units are set on the anchors in the sea opposite the consumer and a connected with him through underwater cable.

SEG's wave power station is offered (Russian #93053457), which is a rotor converter of sea waves energy attached to a conventional energy generator.

While afloat when there are waves on the sea the wave power station generates electric current and directs it through a cable to a consumer (a settlement on the sea shore, a vessel or a producing enterprise).

Specification:

Production technology blowing out standard hollow elements on an automatic machine of BA type. When the term of the service life of the material the power station is made of is over it is utilized.

PROSPECTS

SEG Company seeks partners for building of large energy lines with capacity up to 100 MW and production small energy units for sell.
