The study comes from the cooperation of company Astilleros Balenciaga and Fundación Centro Tecnológico Soermar, has successfully met the objectives of the study: cost of production, installation and maintenance are cheaper conventional methods, can produce a power output desirable, can be operated via remote control systems and activities in deep waters; price of the device with the ability to match payment of the medium-sized shipyards.
Prototype is the size of 1/10 the size of a device is capable of producing 1MW of electricity. Some features of this sample compared with the previous research works are designed sample associated with mooring buoys on the water for the generator maintenance activities in waters 40m deep.
Researchers at the University of Madrid – Spanish explaining new design testing: “The first generation of systems to harness energy from ocean currents is the generator is placed in the water , so maintenance is expensive. The second generation includes, buoy mooring system connected devices operating system for underwater equipment and regular maintenance on the water. Prototype testing our 2nd generation. The main components of the test specimen (such as images) consists of a central device and 3 devices around stainless steel. Equipment containing central generator, the people, the instrumentation inside and outside the rotor system to catch ocean currents.
During project implementation, the ability to test the combination of power and correction was made in the laboratory and in the shipyard, we also conduct exercises at sea scale . The project has additional research on hydrodynamics as well as the ability to test for energy control. These studies have been carried out by the number of different simulation “.
In the future researchers will conduct experiments on larger prototypes to tune and improve the performance of the device.
In this new prototype, the researchers focused on the exploitation of the energy of ocean currents. There is tremendous energy from the ocean can be exploited, such as waves, tides, salinity, temperature difference … It is estimated this energy can provide many times the energy needs of the present people.
