Consider two hydropower scenarios: First, a severe winter storm hits the Midwest. Power outages ricochet across the region, stranding residents in freezing temperatures for hours; and yet, the area's ...

A prototype in-river hydropower system is currently in operation at Igiugig in southwest Alaska. It’s part of a recent surge of research that has pushed in-river hydro power closer to becoming a ...

Replacing turbine runners offers the opportunity to increase generating capacity and efficiency at Ice Harbor dam ...

Jim Carter, who leads hydropower design activities in the Nashville District Civil Design Branch Mechanical and Electrical Section, said the team is working to assess all nine switchyards within the ...

Hydropower is a renewable energy source derived from flowing water. Its history can be traced as far back as ancient Greece, where 2,000 years ago waterpower was used to operate wheels for grinding ...

Yes, vehicles can run on water. For the most part, however, research on hydro-powered energy systems have been hit-and-miss and have presented complications in converting potential energy in water to ...

Hydropower is the world’s biggest source of renewable energy, generating about 16% of the global electricity supply. And it will continue to play a key role as the world looks to meet net-zero targets ...

The Canadian province of Quebec has big plans of becoming the “battery of the U.S. northeast” by feeding power generated from its dams and other hydro plants to millions of people in Vermont, ...

When needed, surge tanks can provide a critical feature to the hydraulic design of hydropower projects. Principally, they can mitigate the overpressure effects of pressure transients or water hammer ...

A new pair of “barochambers”, which simulate the effects of rapid pressure changes on fish, could help increase fish survival rates as they travel through hyrdopower turbines. The mechanical chambers ...

Gunia was a reporter for TIME based in Hong Kong. Natel's Restoration Hydro Turbine (RHT) features uniquely thick blades that allow fish to pass safely through the turbine to continue downstream ...
