Abstract

A moving fluid energy recovery system for generating electricity through rotational motion produced by positioning the present invention in a fluid flow produced by nature or a moving vehicle. The moving fluid energy recovery system has first and second end plates, a plurality of elongated inner vanes, a plurality of elongated outer vanes, and shaft to drive an electricity generating device. The inner and outer vanes each have a substantially curved profile featuring a curve side and an open side. The first and second end plates each has a central bore defined therethrough, a plurality of inner vane slots each shaped to receive a corresponding inner vane, and a plurality of outer vane slots each shaped to receive a corresponding outer vane. The inner vane slots are orientated with the curve side toward the central bore, and the outer vane slots are orientated with the open side toward the central bore with the free ends of adjacent inner vanes positioned in the open side of the outer vane slots.
