In preparation for my first book, “Renewable Energy – Facts and Fantasies,” I interviewed Ray Lane, then managing partner of Kleiner Perkins, one of the world’s great venture capital firms, who told me about his stance with his prospects, “You build the first one. I’ll invest in the next 20. Then we’ll take the thing public and use that cash to build the next 5000.”
I’m 99+% sure that the “first one” of these will never be built, i,e., installing these VAWTs at the base of functioning wind farms. The concept is asinine, as it defies the laws of fluid dynamics.
