To S-F,
So true. It's easy for us to forget that not every solution will work in EVERY place.

I like the idea of a large aquarium acting as a heat sink as my foundation. We could just sweep my daughters high-chair scraps right into a floor grate!

Imagine where our building codes would be if we didn't have several decades of relatively cheap fossil fuels. In the SW roofs might be mandated to be white, and every roof would have 500ft2 of south facing pitch w/o chimneys and soil pipes for solar retro-fit, maybe even conduit stubbed out.

Painting surfaces white in hot climates and dark colors in cold climates is ancient technology that was lost in this country. My only concern with painting my roof white is (current) cultural unacceptance. Who knows, maybe I'll be a trend-setter on the block!

I'll let you know when I paint the tiles the temp delta. I'm going to do more than a few adjacent tiles to thwart conductive transfer.
