:::Thanks for the thoughts. I'm not familiar with the books you mention, so maybe I will check them out. The sort of comprehensive story that you talk about is a pretty tall order when you consider how fast the industry is moving, but I think it is achievable if the story is rooted in fundamentals. I mostly agree about limiting the scope purely to PV, though I do think it is important to motivate the need for PV with some context. However, I think that can be done succinctly without going off on any great tangents. Something I will mull over....
