2021-06-01 MicroHydro power from Water Mains

There is a lot of power being wasted by pressure reducers in water mains. In this YouTube video Matt Ferrell looks at microhydro- and picohydropower turbine-generators that are powered by the drops caused by pressure reducers in water systems. These are capable of generating hundreds to tens of thousands of watts and recover energy that
