Windmill of Death

I find it ironic that the "green" movements is so bent on "sustainable" energy. I'm not sure what "sustainable" means but Brian Dunning has a good idea. It sure isn't good for bats. I've read that the mystery is pretty much solved already. Its the vortices's created by the turbine's blades. This article explains:

"Ninety percent of the bats they examined after death showed signs of internal hemorrhaging consistent with trauma from the sudden drop in air pressure (a condition known as barotrauma) at turbine blades. Only about half of the bats showed any evidence of direct contact with the blades."

Thanks to the SGU podcast for this tidbit.
