A simple system is provided to dramatically reduce the number of bird fatalities and injuries, as these are bird-kills that man should be able to do something about. Essentially, the inventive apparatus comprises one or more instantaneously inflatable mini-airbags on turbine blade leading edges which, in the “stowed position” are tightly conformally elastically wrapped around or juxtaposed to the turbine blade surface(s) and / or edges(s) thereby not affecting the blade's aerodynamic efficiency. The airbag(s) can be activated and restowed or recollapsed very rapidly, thereby not significantly negatively impacting the operational efficiency of the wind machine. In a similar manner, fish-kills or injuries taking place in the turbine impellers of hydroelectric power-generator facilities may be avoided (as opposed to ameliorated) using another inventive system and method taught herein, this one being primarily a collision avoidance system which does not require the problematic alteration of the turbine blades themselves.
