An energy recovery system may comprise a stationary structure and a rotatable structure configured to rotate relative to the stationary structure about an axis of rotation. The energy recovery system may also comprise at least one blade member mounted to and extending radially outward from the rotatable structure, the at least one blade member being configured to interact with fluid currents flowing in a direction substantially parallel to the axis of rotation to cause the rotatable structure to rotate about the axis of rotation. The energy recovery system may further comprise a magnetic suspension system comprising a plurality of magnets and a plurality of coils, wherein the plurality of magnets and the plurality of coils provide a magnetic force that substantially maintains an axial and radial position of the rotatable structure and the stationary structure as the rotatable structure rotates about the stationary structure. |
