Thanks for the post.

I plan on doing some building, well off the utility grid, and I'm always on the lookout for this kind of stuff.

Neat design! I built a cabin in Canada about 300 miles north of Toronto and thought about this as well as a small wind generator using a police car alternator and inverter combination. To increase the thermal mass of the collector, I was going to use large river rocks (which are in unlimited supply up there!) painted black and loosely positioned in the air flow to retain some heat during the night. Alas, the power grid came to me before I could implement the design.
