PS, It’s been a while since I checked the factor e blog. You might want to add roller bearings and a few other vital items to your capability list under “just in case” a supply disruption of the scale of the ’08-9 credit crunch happens again…

I saw a PBS program where a deer-hide yurt was about 50+ degrees F warmer inside from body heat alone. (Just as the deer would be I suppose.) An additional “tent” around the bedding and a single candle made it very comfortable, and this being in Siberian winter. I doubt any significant effect from decomposition could be involved otherwise the compressed bricks would burn. I’d be a bit concerned about seismic vulnerability down there in the New Madrid fault zone. I doubt the building codes are taking things into account…yet. It must be doable since it would certainly be required in that LA apartment construction.

As for all those secondary parts it seems they would all be obviated by simplified design or available cheaply as commodities, such as the bearings and hoses you mention. At least *for now.* The way things are going I’d expect everything to be so restricted by price gouging and lack of competition (domestic especially) as to make everything dear.

Even water is quickly becoming so poisoned that it’s only a matter of time before it will come only with a heavy mark-up, be it monetary or the cost to your health. Maybe the domestic market for water purification able to remove fracking chemicals and well as heavy metal content should be considered. Those are needed right here now.
