Natel Energy is making new designs for turbines that generate electricity in hydropower plants.
The blades have a thicker leading edge that pushes water out in front of it, creating a stagnation zone.
Natel ’s blades are curved, so even if fish are struck, they don’t take a direct hit.
The company has tested its turbines with eels, alewife, and rainbow trout.
A study from the US Army Corps of Engineers found that one new design improved fish safety while also producing more power.
The issue of protecting ecosystems and providing safe passage for fish has sparked fierce debates over existing hydropower projects across the western US and around the world.
Fish-safe turbines won’t solve everything—there are many, many problems in our rivers.
