Abstract: An electrical generator module for harnessing the energy of fluid flowing in a channel subject to gravitational and centripetal forces. The electrical generator module includes a stationary casing portion and a runner portion rotationally coupled to the stationary casing portion, with the runner portion including a set of blades adapted to interact with the fluid. A support arrangement is adapted to secure the stationary casing portion to the interior of the channel in place such that it is prevented from rotating. An electrical energy generator is mechanically coupled to the runner portion and adapted to convert rotational motion of the runner portion into electrical energy.

Abstract: A method for entraining and mixing gas with liquids within a conduit or drop structure, comprising the channeling of one or more liquid flows into spiral flows of predetermined radius (radii), reducing the predetermined radius (radii) to increase the centrifugal forces acting upon the spiral flow(s) as the spiral flow(s) enter the conduit, and allowing gas access to the conduit to mix with and entrain within the spiral flow within the conduit or drop structure. The method can facilitate the mixing of gas with one or more fluid flows and/or reduce the release of gas emissions from the fluid(s) into the surrounding environment.

Abstract: An improved sewer apparatus comprising a maintenance hole and an influent line for carrying sewage to the maintenance hole, a vortex form disposed substantially within the maintenance hole which accepts the sewage from the influent line, the vortex form having a spiral channel of decreasing diameter, and a conduit also disposed within the maintenance hole and fluidly connected to the vortex form and extending substantially downwardly from the vortex form to a flow exit near the maintenance hole base. The improved sewer apparatus reduces the release of odorous and corrosive gas emissions from sewage into the sewer and surrounding environment and improves aeration of the sewage.
