A new technique has been shown to be effective in reducing collisions between birds and wind turbine blades.
Bird strikes are a big hazard for planes too but painting one blade on each propellor of an aircraft black would not be effective, given their rotational speed.
Today’s invention, however, is to equip even jet planes with projectors which create high contrast shadows moving over the airframe.
This would simulate the visual effect of several large, slow moving blades and the imagery could be tuned for maximum effectiveness..
