The most recent Natel/Pacific Northwest National Laboratory test of 186 large rainbow trout measuring up to 500 mm (19. 7 inches) in length, found no meaningful difference between the fish passed through Natel’s 1.9 meter (roughly 6 feet) in diameter turbine and the control group, indicating that the RHT allows safe passage of some of the largest fish ever successfully passed through a compact hydro turbine.
TechCrunch LIVE spoke with Natel’s Gia Schneider and Breakthrough Energy Ventures' Libby Wayman. Watch the full interview here.
Abe Schneider and Sterling Watson lay out the argument for FishSafe™ turbines in this paper published in The International Journal of Hydropower & Dams, Issue 5.
