Various examples of simultaneous ocean wave and current energy harvesting are described, using a hybrid ocean energy converter and a mechanical transfer system therefor. In one example, a hybrid ocean energy converter includes a two-body point absorber comprising a first body and a second body. The two-body point absorber can be configured to transfer a linear relative motion between the first body and the second body to bi-directional rotation of a first input shaft. A turbine can be configured rotate a second input shaft. The converter further includes a hybrid power takeoff including a mechanical transfer system configured to mechanically couple the first input shaft, the second input shaft, an output shaft, and an output shaft.

Simultaneous ocean wave and current energy harvesting

A kinetic energy harvesting device implementing a half-wave mechanical motion rectification (HMMR) mechanism is described. The energy harvesting device may include an energy harvesting railroad tie, where the tie includes a tie housing configured to be coupled to at least one rail. The tie housing includes at least one spring and at least one energy harvester. The at least one energy harvester includes a generator having an output shaft, a gearhead, a ball screw or other motion transmission, and a one-way clutch. Under a force of a passing wheel on the at least one rail, the at least one energy harvester is compressed, which causes a rotation of the ball screw or other motion transmission, a rotation of the output shaft, and a transmission of torque to a shaft of the gearhead, driving the generator in a unidirectional rotation to generate electrical power via the one-way clutch.
