Also, as a side note:
Reducing the need for electricity is a very good goal, in general. If you think about systems outside the literal box that most of us modern idiots have gotten ourselves into, you can find many ways to overcome the un-optimized lifestyle that most of us live. I don't want to build a direct replacement for most of the systems of a modern house, since, they are designed to be barely single use. I'm thinking about building for many generations.
