Claim:
1. A system comprising: a fluid conduit; the conduit including an open chamber; a rotating device mounted in the chamber; the rotating device including a portion protruding through an opening in the chamber and into the conduit; a plurality of fluid impingement surfaces spaced apart on a surface of the rotating device, whereby fluid moving through the conduit impinges on the impingement surfaces and rotates the rotating device; an elbow portion being a part of the fluid conduit, the chamber being positioned in the elbow portion, the chamber having an upstream portion and a downstream portion; and a siphon tube extending along a wall of the elbow portion, the siphon tube having an inlet end and an outlet end, the inlet end being immediately adjacent the downstream portion of the chamber, whereby, in response to a primary flow of fluid through the elbow, the siphon tube conducts a secondary flow of fluid coaxially into the primary flow of fluid through the elbow.
