Attic heat project designed from the bottom up

I have been working on the attic air heating idea and have done most, but not all, of the construction on it. This is an offshoot from the Using Attic Heat for the House thread:
http://ecorenovator.org/forum/solar-...-house-17.html

It uses an open system after all, but where the air enters the vented roof through baffles at the eaves a radiant foil barrier comes down to meet it. This way a thin layer of pretty hot air moves up between the rafters without danger of insulation contamination. Also there is a readily accessible place to change the filter down in the occupied living area. I will be posting pictures soon.

This is a designed from the bottom up system so if if doesn't end up making financial sense here in a moderate climate - California - then it won't make sense anywhere. Having said that, the project is not yet completed, nor have I yet experienced a winter with the system complete, so only time will tell how effective it is. I promise to show you any problems with the system over time and won't keep you hanging if it turns out not to have have been a good idea.
