Hexayurt rapid deployment cardboard cost
From How To Live Wiki
so, here's the rough numbers for cardboard-and-ply-press mass deployments
$100 per panel press - two by fours, plywood, some metal rods or pegs. Assume three minutes per panel, with stacks of 20 or 40 panels being left in the press for half an hour to dry. Guess 20 panels per press per hour.
$4.50 for each honeycomb core, coming to say $7 total with panel facings and glue. But it could be more like $5 total.
- 100 presses = $10,000.
- 100 presses * 20 panels per hour * 12 working hours a day = 24000 panels per day
- 24000 panels * $7 per panel = $168,000 of cardboard etc.
- 24000 panels per day / 12 panels per basic house = 2000 houses per day.
- 12 panels * $7 per panel = $84 per house for panels.
- Assuming $16 of other bits (tape, etc): $100 per house.
- 166 square feet each, or shelter for around five people: roofs over
10,000 per day, assuming there are people to tape up houses and work panel presses.
Now shipping volume.
- A panel weighs about 7 lbs, between facings and core.
- A 20 ft sea container can be loaded to 40,000 lbs (up to about 50,000
lbs I believe)
- 40,000 lbs / 7 pounds per panel / 12 panels per house = 475 units per
sea container.
So you need roughly four 20ft containers per day to keep the presses running. I'm not sure what that is in Chinook loads, but I think it's about 20 runs.
Assume the presses weigh 100 lbs each = 10,000 lbs of presses.
Both the presses and the core are heavy enough to be weight rather than volume bound for the shipping container.
So the first 20ft container ships with 100 presses and and as many panels as can be fitted in, to make the "factory" units. Panels fit 480 per full container (or 40 hexayurts per 20 ft container).
I think the approach is to send two to five 20 ft containers of panels or pre-fab buildings, emergency food, water purification tablets and panel presses. Then as quickly as possible get the panel presses going, and ship in the rest of the infrastructure packages.
What's interesting is the cost for 100,000 people comes out to be about $2 million, give or take, just for housing, and more like $4 m ($40 per head) with a very basic infrastructure package. I think those are quite attractive numbers, really.
