[RE-wrenches] Solar cooker plans request

[Eric Youngren]

Hi Alan,

Aprovecho Research Center  <http://aprovecho.org> in Cottage Grove Oregon
has a great little free publication for downloading called "Capturing Heat"
<http://www.aprovecho.org/lab/index.php?option=com_rubberdoc&view=doc&id=115&format=raw>

That book has step by step illustrated instructions for building the
classic Maria Telkes box cooker from wood, glass, cardboard, aluminum foil
and black paint.   They also discuss rocket stoves and haybox cookers and a
conical solar cooker.

A more recent innovation in solar cooking that I'd love to see grow in
popularity is the blazing tube
<http://blazingtubesolar.com/pb/wp_b62ca705/wp_b62ca705.html>.  That one
uses an evacuated tube SHW collector in a parabolic trough to heat an oil
transfer fluid to move the heat up to a cook box located at a comfortable
working height and potentially out of the sunshine completely with the
addition of a shade structure or umbrella. It seems like the most practical
approach I've seen yet but I've never actually seen one in action.   I see
from an update on their website that they now have a design that integrates
a rocket stove firebox so the cooker can be used with wood or other biomass
during cloudy weather or at night.    That is more of a project than your
friends in Guatemala will probably be able to tackle but I think its a cool
innovation in solar cooking.

all the best,
Eric
