Not only is this thread bookmarked, I also just printed it out so I can frequently refer to it and let it all sink in. It's also something I'm certain Mr. B will "get" and enjoy knowing especially this last bit on off-grid power. (he's been reading Popular Science mag. half his life and has been a life-long fan of Mr. Wizard)
I wish most of my teachers were as good as you at conveying important stuff by making it simple and doable.
