Power per kilogram is a very odd thing to measure. Efficiency/power per square meter is more important…. IMHO of course. This stuff could be way too fragile for most applications. That being said, solar is freaking awesome. I don’t understand how anybody could be ever against anything to do with solar energy. Well, I understand certain companies, but not humans being humans.

Sucks that you are downvoted for simply stating fact. It’s just another symptom of “Are you on my side or their side?”
