Abstract
Abstract Apparatus for extracting energy from fluid motion, i.e. waves, comprising spacing a plurality of floating modules, which may be single floats or arrays, on the fluid's surface far enough apart to minimize apparatus cost and close enough together to utilize the vortex-like action of the waves to extract a maximum amount of wave energy. This spacing is preferably about half the wavelength of the incident waves. The energy extracted by the modules is converted to hydraulic, electrical, mechanical, or chemical energy.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
81 words
An apparatus floating in a fluid that exhibits wave motion, comprising: a plurality of adjoining Hagen arrays; each of said Hagen arrays consisting of a plurality of floating elements, each of said elements being sized to be maximally responsive to a different wave length of said wave motion; each element of said array being separated from the same sized element of an adjoining array by approximately one-half the specific wave length to which said elements are sized to be maximally responsive.
Claim 2
Independent Claim
81 words
An apparatus floating in a fluid that exhibits wave motion, comprising: a plurality of adjoining Hagen arrays; each of said Hagen arrays consisting of a plurality of floating elements, each of said elements being sized to be maximally responsive to a different wave length of said wave motion; each element of said array being separated from the same sized element of an adjoining array by approximately one-half the specific wave length to which said elements are sized to be maximally responsive.
Claim 3
Dependent Claim
27 words
The apparatus as in claim 1 further including means responsive to the wave-length of the waves incident on said arrays for adjusting the distance between said arrays.
