The Tel Aviv-based company, Eco Wave Power, has successfully installed a medium-scale wave energy power plant in the Black Sea. The installation of EWP's system, took place during that month in recognition of the international Mother Earth Day, celebrated in more than 175 countries every year.
The Black Sea provides Eco Wave Power with real-life conditions necessary for the testing of EWP's wave energy devices under uncontrolled wave heights and wave periods.
Among the different tests, Eco Wave Power has examined the characteristics of two different floaters shapes: the "Wave Clapper" and the "Power Wing", and also measured output (KW) at different wave heights and periods, measuring the influence of side waves on the floaters and the connections, connecting the floaters to electric devices and showing an electricity supply (with and without an accumulator), examining the influence of floaters in proximity to each other, and examining the option of uniting both floaters in one electric grid and charging a common accumulator:
On 18 and 19 April, the Black Sea experienced stormy conditions enabling Eco Wave Power to stress-test the floaters' storm-protection mechanisms. “The results were astonishing,” says the company “the floaters survived the storm, without damage”.
In addition, Eco Wave Power concluded that two medium-scale wave energy devices are sufficient for the production of electricity for 6 to 10 households. “Now, imagine what a hundred commercial scale floaters could do!” it says.
The next phase of development will be to move the medium-scale power plant to a different coastal structure, in order to show potential clients that the wave energy generation system can be easily connected to almost any ocean structure. After this, EWP will build its first commercial scale Sea Wave Power Plant, and reveal the construction and production prices, which it claims “will be cheaper than any other renewable or traditional energy generation system”.
"Eco Wave Power is aware of the impact that pollution has on the world. According to a Cornell study, about 40 percent of deaths worldwide are caused by water, air and soil pollution. Such environmental degradation, coupled with the growth in world population, are major causes behind the rapid increase in human diseases. Both factors contribute to the malnourishment and disease susceptibility of 3.7 billion people. EWP wants to prove that there is another way for energy generation. The clean way is the right way for the world," explains David Leb, EWP Founder.
EWP previously tested its small-scale wave energy generation system in cooperation with the Hydro-Mechanical Institute of Kiev in January. The results of the tests were very encouraging, and the officials from the Kiev Institute said at the time that: "All floaters of Eco Wave Power Company have proved their workability… According to the results of the tests, we have reached a decision to recommend enlarging the model to greater sizes."
On this positive note, David Leb says that Eco Wave Power is a young and innovative company in the ocean energy field, which believes in a fast, yet reliable, progress. Leb adds that competitors in the ocean energy sphere have spent 5 to 15 years researching the ocean energy field, without achieving any commercial scale devices, emphasising that Eco Wave Power wants to be different, by offering commercial scale devices within the shortest time frame, and for the most attractive prices.
Eco Wave Power's engineering team has worked hard to fulfil Leb's ambitious dream of executing a fully operational system, able to produce 5KW from each floater, during the first quarter of 2012. This has now been achieved with the launch of the Black Sea device.

17 octubre, 2011NoeblEstuve comdineo el Se1bado, era la primera vez que iba, y la verdad es que la experiencia fue inmejorable. Para empezar, el trato de todas las personas que nos atendieron, no fue bueno, fue excelente (amables, atentos, educados, serviciales, etc ).Para seguir, la comida, muy muy buena la ensalada de pollo asado (era pollo asado de verdad y no como en otros sitios) y mejor afan la calidad de la carne de la hamburguesa (con el tamaf1o real a los gramos que indican, no como en otros sitios).En cuanto a algfan comentario que dice que no le gustan las mesas, sf3lo decir que ya le gustareda al Burger King tener unas mesas con esa amplitud.En definitiva, no sf3lo repetire9, sino que se lo recomendare9 a todo el mundo
