A system includes a bluff body having a tail end and a wake region and slipstream direction behind the tail end. The system further includes a propeller including a hub and a plurality of blades extending outward from the hub. The hub is mounted to the tail end of the bluff body for rotation about an axis. The axis is angled relative to the slipstream direction in both pitch and yaw such that when fluid is flowing over the bluff body, at least one of the blades is in the slipstream and extracts energy to rotate the hub, while at least one of the blades is out of the slipstream and redirects fluid from the slipstream into the wake region. Such autorotation of the hub causes the blades to continuously move in and out of the slipstream to continuously extract energy and redirect slipstream fluid into the wake region.
