This site proves that the kinetic energy of waves can be brought to shore with simple, inexpensive technology that can survive storms.
Using a simple underwater teeter-totter and a 1/8 inch steel cable coming to shore, we were able to cause a 170 pound weight on shore to bob up and down with each incoming wave from a very calm sea. The hydro-kinetic energy transfer is easily seen, showing that the power of ocean waves can be captured on shore with inexpensive, survivable technology. Total materials cost for this demonstration was under $2,000. Scaling up would be feasible with adequate funding.
