A deflector for use in a hydraulic turbine is adapted to be mounted relative to a vertically extending wall of the draft tube. The techniques also include generating a set of files filtered using the search criterion and performing an action specified in the action rules portion on a file included in the set of files. The second layer has oppositely disposed outer and inner second layer surfaces. The dense hydrogen permeable portion has a higher initial concentration of metal than the remainder of the sintered mixture and is present in the range of from about 20 to about 80 percent by volume of the dense hydrogen permeable portion. A turbine mounted on the drive shaft within the outlet converts energy of the exiting wind to mechanical energy.
