"There've been a thousand attempts over two hundreds years to capture wave energy. We chose a different direction because those other attempts haven't borne fruit," said CEO Mark A. Thomas.

I beg to differ with Mark. The sea pump device as used to generate electricity does it with several steps as compared to direct conversion by hydraulic devices. The only advantage that pumping water to land and then sending it back through hydroelectric turbines to the ocean is for energy storage purposes to produce electricity during times when waves would be low.

I am all for wave to electric power conversion but technology in this area is becoming competitive. The bottom line is cost per Mwh. I do not see how the planned Seadog system could compete economically to produce electricity at the same cost level as with other wave technology.
