Received following the 2005 Pakistan earthquake, this shelter idea brings in a very alien technology that is difficult to repair. the cost of transport by helicopter (at over 3000USD per hour for a helicopter that can carry 1 tonne load, and has limited transport volume) is very high.
"
a 15cm pollystyrene minimal geodesic dome type speed shelter, comprised of only one iscosceles triangular panel, 15 of which comprise one shelter module.
Such modules can be very quickly assembled either at a central facility, transported assembled by helicopter specially strung on a single weighted cord, “string of pearls” fashion en masse. The unique structural strength of the design permits such transport.
The extreme simplicity of the module also permits assembly of the triangles, 2 metres to 2.5 metres on an edge, at the destination sites, using polystyrene adhesive and polyurethane foam aerosol, both common construction materials.
Even the bare polystyrene, translucent, is sufficiently robust to last at least a year. Coated outside during manufacture with a sheet of UV resistand plastic film, these would last in the sun indefinitely. Coated inside with plastic film, they would serve as communal showers, field hospitals, WC, etc, for sanitary facilities.
