I still question the technology

no full size window demonstration unit indicates they have problems scaling up from the one foot square we have seen for 2 years now. Yes they have worked on the connections to building wiring (how many buildings have any cabling to allow power contribution at each window though) and with transparency but simple electronics suggest that as they scale up they have more resistance to get from the center of the window to the edges, reducing the collected energy significantly

Until we see full scale windows being demonstrated (20' by 10' at least) I am still watching and waiting - also competitors are gaining ground.
