Turbulent Is Ready to Change the World!
After 2 years of engineering and build iterations the team of Turbulent has finished its first 15kW low-head hydropower turbine. This is a scalable technology that can be installed at any kind of wate...
Underwater Balloons Could Give Us A New Way Of Storing Renewable Energy
While solar or wind farms are now contributing more energy than ever to the world's power supply, traditional energy sources are often required at peak times or to supplement renewable sources during ...
Turbines Harness the Power from Water Flowing Through City Pipes Underground to Power Portland Homes
A Portland water pipeline is now producing enough electricity to power more than a hundred homes. Suddenly, when Portland residents turn on the tap they are getting water and energy for the price of o...
Arch dam
An arch dam is a solid dam made of concrete that is curved upstream in plan. The arch dam is designed so that the force of the water against it, known as hydrostatic pressure, presses against the arch...

Arch-gravity dam
An arch-gravity dam or arched dam is a dam with the characteristics of both an arch dam and a gravity dam. It is a dam that curves upstream in a narrowing curve that directs most of the water against ...

Check dam
A check dam is a small, often temporary, dam constructed across a swale, drainage ditch, or waterway to counteract erosion by reducing water flow velocity. Check dams themselves are not a type of new ...

Dry dam
A dry dam is a dam constructed for the purpose of flood control. Dry dams typically contain no gates or turbines, and are intended to allow the channel to flow freely during normal conditions. Durin...

Diversionary dam
A diversion dam is a dam that diverts all or a portion of the flow of a river from its natural course. Diversion dams do not generally impound water in a reservoir. Instead, the water is diverted ...
