S.D.E. is a world leader in the planning, building and marketing of power stations, producing power from sea waves . SDE's method consists of using sea wave motion to generate hydraulic pressure, which is then transformed into electricity. The system takes advantage of the wave's speed, height, depth, rise and fall, and the flow beneath the approaching wave, thus producing energy. A full-scale model was operated in Israel and produced 40ekW for almost one year. The model has been checked and approved by experienced engineers

Currently, the company holds Letters of Intent and orders from state leaders and electric companies in an approximate amount of US $3 billion dollars. In order to implement them, it welcomes proposals for investment, either through a sale of its shares or royalties from future revenues.
