This (one of several videos posted) is a backyard trial which took place before deployment to the ocean, meant to illustrate the concept only. The particular unit here shown is now sunk and probably lost in about 4 meters of water, near Room Island off of Conakry Guinea. The device we succeeded with was larger, and is still in place as of February 28, 2009. This does not show the 50 gallon drum which is evident in the videos of the first successful trial, since this only shows the portion of the unit located underwater, and the frame on shore.

The assumption of about 1 KW...is too high....you are assuming that the wave will cycle about 1 sec...the 4 feet up and down is a better assumption ...but the wave cycle will be about 5 seconds or so...Hence, energy extraction as shown here will be limited to say less than 250 watts...if you get the 4 ft stroke....In reality, the behavior including friction will be definitely produce 100 watts or less
