Claim:
A water current powered motor for extracting raw power from water and converting it to kinetic energy, comprising: means for transferring the power from the vanes to the shaft and diverting the water to the vanes for greater power; means for collecting the transfer of raw power from the water current; means for transferring power from the power cylinder to the work; means for diverting water into the unit; means for reducing water pressure against the forward side of the vanes thus decreasing the power requirement of the unit to flow its vanes back into the on coming water current; means for serving as a housing structure to contain the raw energy contained in the water current; means for preventing natural water current from effecting the outwardly flow of water passing through the water powered current generator; means for the vanes to collapse in order to reduce water resistance when the vanes are moving in a non-power direction; means for permitting the vane parts to fold on predictable lines; means for stopping the vanes from going past their proper position; means for retaining the power shaft into its proper location, stabilization of the power shaft with as low a friction coefficient as possible, accepting both thrust and radial pressures exerted on the power shaft; means for containing the water inside the unit so that the fins can extract the energy, it also directs the water current so that current energy is contained rather than lost to fin resistance; means for containing the water inside the unit so that the fins can extract the energy, it also directs the water current so that current energy is contained rather than lost to fin resistance; means for orientating the water current generator's water inlet to the direction of the oncoming current for the most effective association of current flow, the direction vein permits the unit to be used in areas of changing current direction such as in tides, ocean currents and tide effect waters; means for preventing unwanted and large debris from entering the unit and clogging it; and means for enabling the water current generator to pivot on its axis for the purpose of rotating the units opening or water inlet into the direction of the oncoming water current.
