Knowing that humans have been using wind power for at least 5,500 years. Windmills have been used for irrigation pumping and for milling grain since the 7th century AD.
Brings to mind that sometimes first ideas just need to be tweaked a little, to keep up. And when all is said and done, just maybe our getting back to basics could make our planet better.

PS. I'm also curious as to how far new tech wind power has progressed since the Rattlesnake Island Association did their study.
