Abstract A system is described for manufacturing hydrogen gas which utilizes the energy of surface waves in a liquid, such as an ocean. The system first converts the energy of surface waves to mechanical energy by apparatus comprising a buoyant helical member mounted for rotation about an axis. The pitch of the helical member can be matched to the length of the expected waves and the member is floated on the surface with its axis oriented so that each wave traverses the helix lengthwise and buoyantly supports successive sections thereof causing it to rotate about its axis. The helix is coupled with rotary driven means to an electrical generator, wherein the mechanical energy is converted into electrical energy in the form of DC current which in turn is employed to electrolyze ocean water to produce hydrogen gas which may then be compressed or liquified, e.g. for storage and transportation.
Apparatus for manufacturing hydrogen gas from sea water, said apparatus comprising in combination: means for converting the motion of gravity waves in sea water to electrical energy in the form of DC current and including an elongated bouyant member curved about an axis to form a helix and means for mounting said helical bouyant member for rotation about said axis, said means for mounting including means for suspending said helical bouyant member so as to enable said member to float partially submerged with respect to the crests of said gravity waves; means for electrolyzing a quantity of sea water, using said electrical energy, to form hydrogen gas; wherein said axis of said bouyant member is oriented substantially parallel to the approximate mean direction of propagation of said gravity waves.
