Proving once again that there is little new under the sun (or the waves) is this 1932 version of the wave power generators that we showed here and here. It works on the basis of an "inertia motor" where "When a wave starts to lift the hollow sphere, the massive weight inside, because of its inertia, resists the movement and exerts terrific pressure in the lower cylinder. Finally the inertia of the weight is overcome. Then it possesses momentum. When the sphere reaches the crest of a wave, the combined effort of the momentum and the recoil of the huge, semi-elliptic springs exerts an equal pressure in the upper cylinder. The tremendous pressure is applied to oil, which, in turn, operates a special turbine which runs a generator. The current is conducted to the shore by submarine cable."
Phil Slade on 25 May 10"Wave Hub on course for summer deployment 17 May 2010 Wave Hub, the pioneering marine energy project, is on course to be deployed this summer with fabrication of sub-sea cables and the hub itself nearing completion. Wave Hub will create the world's largest test site for wave energy technology by building a grid-connected socket on the seabed, 10 miles off the coast of Cornwall, to which wave power devices can be connected and their performance evaluated."
