This morning on BBC News, Andrew McLoed (the UN's Head of Operations
in Pakistan-administered Kashmir) spoke about helping 3 million homeless
people keep warm in -10 C weather, after the fall earthquakes that killed
over 75,000 people. He said they needed warm coats and shelters. Now they
have tents and corrugated iron shelters, and they are building more, with
lots of iron sheets.
Have they considered substituting Dynaglas corrugated polycarbonate for
the corrugated iron on south walls of shelters? I imagine that Kashmir
gets lots of winter sun and snow, especially at higher altitudes, in
the villages shown at 6500 and 7500 feet.
Other alternatives include a long multi-family plastic film greenhouse
with an air heater built into the south wall or "replacement foam
insulation," with the space between 2 layers of 5 cent/ft^2 4-year
greenhouse polyethylene film filled with air during the day and soap
bubble foam at night.
I suggested (to no avail) some things like this to a German University
engineer at the 2003 Sustainable Resources conference in Boulder. He was
designing a better woodstove for mountain people in Nepal who have to
walk long distances to collect firewood :-)
