Thanks for the link. Interesting read. @Mods: I just noticed that there's half a dozen threads about Tesla Energy, Tesla Powerwall, Tesla Powerpack, Stationary Storage business in general, etc., and I think many of us would appreciate a dedicated forum section for Tesla Energy (without subforums for the start), but within Tesla Motors Forum, and not in the General Forum, since it's discussions about a core TM product, the respective market and competition.
