The SDE Sea Wave Power Plant is a type of renewable energy power plant utilizing sea wave energy for the production of electricity.
Description [edit]
The device is made of buoys which are placed on a breakwater, or on some other sea based structure, which create a vertical motion, according to the frequency of the sea wave. The buoys' movement presses on a hydraulic liquid, which is regulated by systems that convert the energy into circular systems. These systems operate an electricity generator and the process culminates in electricity production. The system's innovation is based on its self-correcting mechanism whereby, should a large wave overwhelm the buoy, it would flip over and then "wait" for a lower tide to flip back. The system's high survivability capability is based on the fact that only 10% of its components are submerged in sea water.[1]
Developer [edit]
The device is developed by Israeli company S.D.E. Energy LTD. S.D.E. has built and tested eight different models of its system, culminating with a full-scale model that operated and tested in Jaffa Port located in Israel and produced 40 kW for a period of a year.[2]
In March, 2010, S.D.E. is preparing to move into the construction phase of two of its projects in the islands of Kosrae, Micronesia and Zanzibar. On 27 July 2010, S.D.E. announced it has started building its first large-scale sea wave power plant with a maximum capacity of 50 MW in Jaffa port. At the initial phase the plant capacity will be 100 kWh.[3]
