Very cool site Treecaster.
The Gupta State Failure Management Archive is now online at Archive.org. The collection has over ten hours of Public Domain video and audio teaching a set of thinking tools for extreme resilience, ideal for downloading (4.3gb HTTP) (4.3gb Bittorrent) and burning on a DVD for handing out to people.

The hexayurt shelter can cost less than a relief tent, is designed to be manufactured anywhere in the world at any scale, from local materials, as Free hardware, to house humans in need. The Hexayurt Project maintains the designs and makes them freely available to you.
To make the simplest hexayurt, make a wall by putting six sheets of plywood on their sides in a hexagon. Cut six more sheets in half diagonally, and screw them together into a shallow cone. Lift the roof on to the wall with a large group of people, then fasten it down with more screws. Seal and paint it for durability. Your basic hexayurt is complete.
This shelter will last for years in most climates and costs less than $100. This basic design can be improved with proper windows, doors, room partitions, stove fittings and other architectural features. More durable materials could give it a very long life. The basic building materials are available within a few hours drive of almost any large settlement in the world and can be cheaply imported in enormous quantities if needs be.
Here are the key points.
Hexayurts can be built in plywood/OSB for less than $100 for a 166 square foot (15 sq meter) building. See the Plywood hexayurt how-to video and The Hexayurt in Haiti? technical document on an ultra-rugged design for hurricane risk areas.
Hexayurts can be made in a variety of sizes using simple tools from industry standard 4'x8' (1.2x2.4m) sheets with zero waste and can be made successfully from many different materials, like plywood, OSB, coroplast, composites, hexacomb cardboard or other honeycombs and polyiso insulation boards.
We also have new hexayurt geometrices
from Edmund Harriss on 450 square foot "nearodesic" domes which share the zero-waste property with the hexayurt itself.
from Scott Davis and Dylan Toymaker on the H13, a new hexayurt with expanded headroom and a full-height doorway.
Hexayurts are public domain with no copyright or patent, meaning anybody can build as many as they like for free.
Depending on your choice of materials, a Hexayurt can last for years or even decades. In some long stay applications this could cut the cost of providing shelter to 10% of the cost of using standard relief tents. The hexayurt enables regional shelter self sufficiency, where in a crisis, pre-trained local builders or military personnel can work with first responders to rapidly create shelter from materials in the local supply chain, typically plywood or OSB.
Mail Order Tape
A key material involved in constructing Hexayurts is tape. Specifically, 6" wide bidirectional filament tape. In English, that's a six inch wide tape with re-enforcing fiberglass strands running in both directions, so that it will not break or tear under almost any imaginable circumstance, including howling playa dust storms. It is amazing and very expensive. Other tapes have been tried-- they aren't great in playa conditions, and those who went off the beaten path regretted it. Some innovations are underway, we'll see what results come back (and we'll take reports of success w/ other tapes in the discussion section.
Mail Order 240 yards bidirectional filament tape such as 3M 8959 "Extreme Applications" packaging tape, 6" wide. AKA as "JVCC 762 BD." 6" is not a standard width, it usually costs around $30 plus shipping. 5" tape is perfectly good. For certain steps, you can use 3" which is half the price and a lot easier to work with. 3" tape is ideal for sealing the panel edges during preparation. If you are employing the "classic construction" approach, you will seal all panel edges prior to assembly: that step alone takes 132 yards of tape.
You also use the tape calculator spreadsheet to figure out exactly how much you need.http://hexayurttape.com/
aka GoodBuyGuys. They've been helpful to Vinay, they know what you want the tape for and sell a good product at fair prices. $30 per 6" roll, they also now have 3" wide tape, and case prices as well.
Findtape.com, sold as "JVCC 762-BD Bi-Directional Filament Strapping Tape." $32.67 per 6" roll, plus every other width imaginable, case pricing (36 count) available.
Taperite.com has 3",4", 6" tapes. 6" for $38.72/roll, discount pricing starts at 6 rolls (smaller than case sizes above!)
One supplier is Tapes Unlimited, 1245 Hartrey Ave, Evanston, IL (847) 866-6060. They do not have a web site. But they know Hexayurts and are very helpful.http://penmar-industries.com/specialtytapes.html#sptp
Penmar Industries also carries a bidirectional filament tape in 5" which looks perfectly serviceable although I have not used it personally.http://thetapeworks.com/
also has a 6" bidirectional filament tape available, although possibly not in stock.
Check with 3M about direct ordering because sometimes Tapes Unlimited sells out.
Also hillas.com, these guys apparently sell by the roll as well, but it is a custom order product, so give them at least 10 or so business days to deliver.http://taperite.com
are aware of the Hexayurt Project and have excellent tape...I couldn't find this tape here.
Office superstores like Staples carry 3" filament tape (strand tape) which will do in a pinch
Kragen/O'Reilly Auto Supply sometimes has 3".
Total cost: $130 with shipping, perhaps?

Hmm, I could make a very good chicken house with this design.
