The invention relates to a method and apparatus for gradually converting marine wave energy into electricity. The energy reserve provided by wind power holds enough energy for the needs of the entire mankind. The invention provides an efficient means of putting this energy reserve to practical use. Mounted on a rotating power shaft is a pair of form parts, the convex and concave shape, especially the round-pointed open V-shape of which reverses its orientation by 180 degrees, i.e. turns from convex to concave, whenever the power shaft makes a rotation of 180 degrees. The circular motion of water occurring in a wave drives such a turbine effectively while the wave dies out. The pair of convex and concave form parts extends helically around the power shaft, whereby water currents in all directions, which come to contact with the pair of form parts, produce a rotative moment.
A method for producing electrical energy from an energy reserve established by marine waves in alternating motion, which is recovered gradually for use directly as electricity by means of a difference in flow resistance form factors by using a pair of form parts engaged with a power shaft, wherein the pair of form parts are double-faced and structurally solid, and each form part has in cross-section the shape of an open V, the open V having legs intersecting to form a ridge on an outer side of the open V and a groove on an opposite inner side of the open V, the inner side of the open V bounding the space between the legs of the open V, each form part extending helically around the power shaft by 180+180 degrees, and being rotated by the kinetic energy of waves through reversing the form parts' form factor always at 180-degree intervals, the power shaft being supplied with force in both directions of alternating wave motion as the pair of form parts has its halves alternately presenting low and high resistances to flow.
Wave power apparatus for gradually converting marine wave energy directly into electricity, said apparatus comprising a power shaft, an electric generator driven by the power shaft, a pair of form parts mounted on the power shaft, each form part of which has a first form factor proportional to flow resistance in a first direction of flow and a second form factor in a reverse direction of flow, said form parts translating kinetic energy present in the inertial force of waves into power shaft rotating energy on the basis of a difference in the form factors of the form parts, wherein the first form factor is established by a concave surface of the form part and the second, substantially lower form factor is established by a convex surface of the form part, and wherein the pair of form parts constitutes a double-faced continuous or stepwise proceeding helical concave and convex form around the power shaft, each form part having a cross-sectional shape of an open V, the open V having legs intersecting to form a ridge on an outer side of the open V and a groove on an opposite inner side of the open V, the inner side of the open V bounding the space between the legs of the open V.
A paddle wheel connected to an electric generator, wherein the paddle wheel is moored and braced to the sea floor near the water surface either underwater or partially overwater, and that the paddles of the paddle wheel have the configuration of an open V-shape and the rotating shaft of a rotor consisting of such paddles is codirectional with a moving wave front, i.e. the crests of waves, and takes the rotative force from a current circling inside the wave and applied between the legs of the V-shape, the legs of the V-shape intersecting to form a ridge on an outer side of the V-shape and a groove on an opposite inner side of the V-shape, the inner side of the V-shape bounding the space between the legs of the V-shape.
