An energy harvester capable of providing motion from fluid flow includes a Magnus rotor defined by a cylinder driven by a motor causing the cylinder to rotate so that lift is created by the fluid flowing past the cylinder. A channel or system may be provided to direct the fluid flow to the cylinder. The rotating cylinder configuration is integrated into a mechanical device which is designed to transfer the lift into a mechanical motion to drive a generator. The mechanical motion due to the created lift is reversed by using a stalling mechanism and counter balanced mechanism. This creates a bidirectional motion which can be captured and used to drive a generator. The device can be utilized in either air or hydraulic environments. A modification of the energy harvester can be configured to utilize the electricity generate to produce hydrogen for use in fuel cells or for combustion.
