It seems like wind turbines would have to be thick and dense to significantly slow down the wind. If they did so to any degree the effect would be bounded by some reasonable distances above and around them. Man made heat islands do seem to significantly affect weather patterns over large areas but their areas of influence are huge and dense. At the least wind turbines can extract energy from wind without slowing it, as they can extract significant energy by just making the wind turbulent, thus increasing its entropy. That they make the wind downstream of them at last locally turbulent seems to have a lot of evidence to support it in terms of the bird kills, etc. The absence of clear and obvious evidence that they substantially slow the wind could be meaningful. ------------------------------------------------------------------------ arnyk's Profile: http://forums.slimdevices.com/member.php?userid=64365 View this thread: http://forums.slimdevices.com/showthread.php?t=104207 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
