Conduit hydroelectricity : ウィキペディア英語版 | Conduit hydroelectricity Conduit hydroelectricity (or conduit hydropower) is a method of using mechanical energy of water as part of the water delivery system through man-made conduits to generate electricity. Generally, the conduits are existing water pipelines such as in public water supply.〔(【引用サイトリンク】url=http://www.canyonhydro.com/projects/conduit.html )〕 Some definitions expand the definition of conduits to be existing tunnels, canals, or aqueducts that are used primarily for other water delivery purposes than electricity generation.〔(【引用サイトリンク】url=http://www.hydro.org/tech-and-policy/technology/conduit/ )〕 Historically, electricity generation from water pipelines was rare because the water would have been pumped by other engines in the system prior to the intake of water turbines to generate electricity. The energy generated from the turbines would have been offset by the power used in pumping, canceling out the power generation benefit. However, there have been renewed interests to apply this method to recover energy when there is a need to reduce pressure in the water supply system that is normally done through pressure reducing valves. The conduit hydroelectricity generation in this case can be done by replacing the pressure reducing valves with small turbines and electrical generators. ==References==
