    Gohodo Victor reacted to Brian_SA in Hydro turbines operate at a terrible efficiency   
    Tim, your statements are false and i disagree with you. I am a Hydro Engineer based in south africa. Efficiencies add up through a system by multiplying each one together. Let me give you an example from our hydros we supply:
    Overall efficiency = Turbine x Generator x hydraulic(pipeline) x electrical losses(inverter, rectification etc.)
    Typical calc: Turbine at 90% x Generator at 90% x Hydraulic line at 95% x Electrical losses 90%
    Therefore overall efficiency is 0.9*0.9*0.95*0.9= 69%
