Pentair began with five engineers and a plan to build high-altitude balloons. Sixty years later, its pumps, filters, ice machines and pool controls reveal the sprawling business hidden inside an ordinary glass of water.
InPipe Energy is a Portland, Oregon cleantech company that turns the wasted pressure inside existing water pipelines into carbon-free electricity. Its flagship HydroXS system pairs micro-hydropower turbines with smart pressure controls that retrofit into municipal, industrial, and community water infrastructure - no dams, no new construction, no environmental harm. Founded in 2016 by Gregg Semler, the company helps water utilities and cities generate reliable baseload power, cut energy costs, and decarbonize aging infrastructure.
Gregg Semler is the founder and CEO of InPipe Energy, a Portland-based company that generates clean, around-the-clock electricity from the water already flowing through municipal pipelines. A serial clean-energy entrepreneur since 2000, he previously led PolyFuel, ClearEdge Power, and Lucid Energy, and spent years as a venture investor in the sustainable economy. His pitch is contrarian: instead of covering the planet with solar panels and batteries, harvest the predictable, weather-proof energy hiding in the millions of miles of pressurized pipe that move our drinking water.
