The house will be heated by waves

23.04.2007
Specialists of the “Center for Renewable Energy” company have developed and patented an original design for a small but very efficient wave electric power installation. With coefficient of performance reaching 25 percent, capacity of a single module of such installation would make 10 kWt. The distinguishing feature of this installation is simplicity of its production and a relatively low cost price.

Apparently, the idea of using sea wave energy is almost as old as the world. If romanticts prefer to fall into a reverie on the shore near sea waves and/or to air young maidens accompanied by the wash, pragmatists have been thinking for centuries how to utilize enormous power of the sea. The first patent for water energy utilization was granted in France nearly 400 years ago, so the idea has already been thoughtfully studied and even driven to industrial implementation.

Experimental wave electric power stations are already operating in Norway and Portugal, there is an experimental tidal electric power station functioning in Russia in Kola Peninsular, Japan has beacons and lighthouses utilizing wave energy, and in India, the Madras port lightship is running on wave energy. Nevertheless, among the variety of constructions there has been no coastal installation so far, which, would convert sea-wave energy into electric pwer and be relatively small, simple and, most importantly, inexpensive. Such an installation was designed by the specialists of the Center for Renewable Energy, its offices being based in Moscow and St. Petersburg.

Its principle of operation is rather simple. A double-armed lever is fastened on the post hammered in the sea bottom not far from the coast. There is a flat float on the one arm (the one which is longer). The other is connected to the water pump plunger. Waves raise the float, at that the pump injects water into the reservoir-storage on the coast – something similar to the water tower. When flowing out of this reservoir under the action of gravity, water gets on the hydrotreater’s turbine wheel fin, rotates it, and hydrotreater produces electric current – likewise any electric power station.

As a result, by using two absolutely free forces – wave energy and gravity, relatively inexpensive electric power can be obtained, and most importantly, this can be done without destroying natural fuel supply or any damage to the environment.

The indisputable advantage of such installation is its simplicity. Firstly, its proper electric generator is located on the coast – consequently, it is easy to assemble and there will be no need to lay out a cable for electric current transfer, as it should be done for the overwhelming majority of current wave installations. Secondly, the installation consists of parts simple in production, and the principle of operation of each element is well-known. Therefore, it will be easy to produce and assemble such installation – it is much easier and less expensive than to produce a big wave electric power station. And finally, the electric module of the new installation needs nothing but sea waves to operate – the module is capable of running quite independently, and this is a significant advantage. This is particularly important in the locations where electric light disruptions occur regularly due to broken off wires.

Is such an installation available for purchase now? Alas, not yet. So far, there exists a small working model, but this summer the designers are planning to test a full-scale model in real-life environment – to revise and optimize some parameters. However, the authors are absolutely sure of success. They have already made sure experimentally that the float of only the 5 cubic meter volume will be able to ensure capacity of no less than 5 kWt at sea roughness of 2 to 3 points. “It is absurd not to use a whole ocean of energy, which is splashing literally close by, says one of installation designers, Anton Kirunin. So, after testing we are planning to develop engineering documentation for the industrial-scale plant – and its production can be started.”

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
