1. A system comprising:
- a fluid conduit having a first diameter;
a cylindrical chamber coaxially mounted in the fluid conduit, the chamber having a second diameter greater than the first diameter;
an inlet at a first end of the chamber, the inlet having the first diameter and being connected to the fluid conduit;
an outlet at a second end of the chamber opposite the first end, the outlet having the first diameter and being connected to the fluid conduit; and
an impeller having a shaft coaxially and rotatably mounted in the chamber, the impeller having a plurality of impeller blades mounted on the shaft, rotation of the blades defining a diameter greater than the first diameter and less than the second diameter.

Abstract
A fluid conduit has a constant diameter and a chamber in the conduit has a larger diameter than the diameter of the conduit. Within the chamber, an impeller is rotatable by fluid moving through the conduit and the chamber. The impeller includes blades extending spirally along an impeller shaft. When rotated, the impeller blades define a cylinder having a diameter greater than the conduit diameter and less than the chamber diameter.
