Hi Allan,<br>
<br>
You might remember Sharkey, one of the original, perhaps founding
RE-wrenches, who has craftsman skills that would easily qualify at
an artist level. He built his own solar thermal panel and in the end
acknowledged that (even with his outstanding skills) would have been
wiser to buy (rather than build) the finished product. <br>
<br>
The last time I looked, at least one of the solar cooker
manufacturers built their model to be collapsible into a much
smaller package than the "traditional bread box" which certainly
would aid in storage and shipping. An actual sample is IMHO so very
superior to any plans/drawings in as much as it allows the new user
to maximize their creative skills to reverse engineer their local
knockoff AND compare their results with what is available from an
existing commercial product. One of the details that I remember from
some 15 years ago was the gasketing on the commercially manufactured
unit that kept the heat in the box quite well.<br>
<br>
In the 13th edition of the Solar Living Sourcebook, copyright 2008,
the author mentions "The non-profit Solar Cookers International
group provides cookers and simple cardboard and aluminum foil
construction plans to developing countries." A Google search yielded
the result below.<br>

Wrenches,<br>
Our closest rural neighbor spends part of each year in Guatemala.
She emailed me a request:<br>
<blockquote>
<div dir="ltr"><span>I have a friend who can
help me construct a solar oven or cooker if we can find good
plans. Illustrations are the most important. I have access
to pine lumber, glass, but nothing too technologically
advanced.</span></div>
<div dir="ltr"><span> I
also want to buy panels when I get back to NM to install on
my home here. I have an electrician friend with experience
here.</span></div>
<div dir="ltr"><span>Any help is greatly
appreciated<br>
</span></div>
</blockquote>
This is a bit off of our usual topics, but still consistent with
RE. Can anyone send a good web link or other resource that meets
this request? I will forward it on.<br>
Thanks, Allan
