According to most historic sources the birth of hydropower, using water to generate electricity,started around 1880. Over the past 135 years we've seen steady improvements and growth that have allowed us to benefit from naturally free flowing water. But what about the hundreds of thousands of gallons of water flowing through pipes and sewer systems each day? It looks like the city of Portland is testing new "Smart Pipe" technology to tap into additional energy generation. These pipes not only contain sensors that monitor water quality and water pressure, but they also incorporate hydroelectric turbines which capture energy from the normal day-to-day functions and flow of water pipelines. This exciting innovation could benefit cities and even help to power large manufacturing plants across the globe as œSmart Pipe technology is perfected.
