摘要 |
Certain example embodiments of this invention relate to techniques for collecting run-off and/or draining water from commercial or residential sites, filtering out the liquid, and using the filtered liquid to engage one or more turbines to generate electricity. In certain example embodiments, the one or more turbines are located downstream of filtration, grease-collection, and/or other purification devices. The electricity generated by the one or more turbines may be stored in batteries, serve as a power source for an active drainage/filtration system, used for other activities in or around the site, etc. In certain example embodiments, elements (such as sidewalls, vanes, and/or the like) may be provided upstream of the at least one turbine and downstream of the filtration subsystem, with adjacent elements defining constriction locations therebetween to help accelerate the flow of fluids passing therethrough.
