Abstract (en)
[origin: WO2005080789A1] A powerplant for use in high head applications (dams) which allows marine animals (fish, otters, turtles, etc.) to swim safely from one side of the dam to the other. The turbine blades which take energy from the water to produce electricity have a large hole through their center. They are arranged one behind the other in such a way that the velocity of the water is decreased as it passes through each blade. The large holes through the center of the turbine blades and the decreasing of the water flow, while increasing the amount of energy produced, will allow marine life to easily swim back and forth through the dam.
