Could this be the solution...

to reducing bat mortality near wind turbines? Scientists have now discovered that radar signals might drive bats away from the low pressure wake generated by the rotating blades, which in turn ruptures the capillaries in their lungs causing fatal hemorrhaging.

Remember, bats need friends.
