<DIV><FONT face=Arial size=2>Hi Ray,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>In Arkansas we used whole-house fans or just a box
fan in the open attic access hole to exhaust hot air out of the attic vents,
closed the curtains on the south-facing windows and opened the lower sash on the
north-facing windows to let cool air in.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Migration to a better climate also works, but bring
lots of wampum if you trek to the southern California coastal
region.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I'm reminded of an old Arco Solar slide of some
people in Upper Volta (now Burkina Faso) standing next to a solar array and a dc
pump with water gushing out of a dug well. Behind them is desert that looks like
a Martian landscape. Those folks did not need solar water pumping. They needed
suitcases and good walking shoes to migrate from desertification.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>There will be a lot of migration as climate changes
affect coastal regions and rainfall patterns change and politics. For example,
some of the Pacific Island villages threatened by rising water, the Mesa Verde
Cliffs Anastasi Indians and drought, the Pilgrims to the Americas, etc. A lot
can happen in a couple million years. Adaptation, migration,
extinction.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>In the meantime, there's lots of fun to be had
getting Americans to cut their energy consumption five-fold and/or helping
people with no electricity improve their living standards without
polluting like Westerners.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>There's hope for us yet. Keep up the good work.
</FONT></DIV>

<DIV><BR></DIV>Hi Joel;

<DIV>I made a list of strategies we use a couple of emails back in this
string. I'll reiterate:</DIV>

existing homes?</FONT></DIV>
