Nice find, Icbc123. Yes, Fyerdriver I saw that too. Since they seem to be exploring a partnership w/ NW, I would think that the residential unit proposed to be developed by NW would be a joint project. They have expertise in-hand w/ Sauer Energy. I am not sure if Sauer's rooftop mounted unit, Windcharger (Correct?), has been fully developed? Perhaps patents pending, too?
