Well, this is a timely topic, as I just recently learned that the terrible eczema all over my armpits, neck, shoulders, and ribs is from the lycra in my bras. I am always a cotton person but almost every cotton bra has some percentage of lycra. I did find cottonique and ordered one of their 100% cotton bras, but their sizing is lousy -- they don't even have D in any size under 38, and in many styles don't have C. I got, I think, a 36C lace-up bra with no stretch whatsoever and I am able to tie it tight enough around the bottom, but the cups are flat so it squashes. I wish I could find an in-person fitting place that would have 100% cotton in my size, but it's almost impossible to find even online. Cottonique comes from overseas and you need to pay shipping to return so I only bought one. I found another company that charges over $90 per bra for their 100% cotton but it didn't look like they had decent sizes. It is such an odd stance that larger cups should only be offered for larger rib cages... as if bra companies don't understand what a large cup means!
We are just about to launch into homesteading full-force on an empty high desert mesa, so I can't imagine how many years it will be before I can try to sew my own (will be living in a tent for much of the first year). I think for the forseeable future I'll be alternating between nothing (which I can tolerate max one day at a time), tank with psuedo-bra (still some lycra but not so tight so bearable a day at a time), the cottonique bra, and a cotton sash tied just under my breasts (sweat-band only, also only ~1 day at a time). Ugh.
So I'm curious about the upshot of the bigger design... does it seem like the secondary solar collector provides the boost that you expected? Is it worth putting on a secondary collector, or not necessary?
I have another question about the design differences between the two collectors... the Missoula collector has the area under the collector enclosed with glass. Does that seem to make any difference? Do you think there's any advantage to enclosing that area, or is it unnecessary?
I'll be building my dehydrator in high desert so I'm thinking I might not need the extra boost. It is quite arid where I am, but it does get cold at night.
Eric, did you look into the Alliance, NE geothermal greenhouses that another responder linked? They grow oranges and tons of other subtropical plants year-round on the Nebraska plain.
I ran across this your post by googling "Taos geothermal greenhouse" because the materials put out by Russ Finch (designer of the Alliance greenhouses) said there was one built in Taos and I am trying to track it down. I have a building site in Prewitt, NM (90 min W of ABQ just off of I-40, elev. 7200') where I'd like to build, and am trying to locate that Taos greenhouse since I think we'll have a similar environment/similar issues. If you learn any more about them, I'd love to hear it!
