I recall seeing simple cardboard box models being demonstrated by NMSEA
at Solar Fest. They would get to about 275 F, while their huge trailer
mounted mirror device got to about 325F, as I recall. The main flaw in
all solar cookers is no backup source of heat, so that if it gets
cloudy, etc. the temp could drop and allow stuff to possibly spoil. I
always wanted to come up with a design that used propane if the temp
couldn't be maintained with solar. I think we would see much wider
adoption of the technology. Adding thermal mass would help too. I
think that is one advantage of the traditional Orno adobe ovens: they
conserve wood, and heat very evenly.
Solar cooking won't replace a skillet, but it lends itself to crockpot
type simmering; if the sun is shinning....

Wrenches,
Our closest rural neighbor spends part of each year in Guatemala. She
emailed me a request:
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.
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.
Any help is greatly appreciated
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.
Thanks, Allan
