I too am interested in compound parabolics. Several ray traces that I have seen show up to 3 reflections before hiting the pot. I am interested in what can be done without requiring multiple reflect ...

For the past several weeks I have been intensely working on two computer programs to analyze the performance of solar panel cookers. I chose the CooKit as the first application.

To use the progr ...

Hi Sharon,
I checked out your EZ-3 cooker and will probably build and test one when I have time. I have built a ROB cooker that is simalar to the EZ-3 except that the pot rather than the whole cook ...

I have seen too many cooker building workshops where the par ...

We are leading a cooker building workshop that consists of two two hour sessions. The question that I would like the groups opinion on is: What is the best cooker to build? There are 12 people signe ...

I have done some two dimensional ray tracing with Mathcad. It is a bit tedius, but works quite well. The idea is to write an equation for each ray and then use the graphing function to plot the ray. ...

On Saturday July 26 we cooked a complete meal for 15 people totally in the sun and did a power point presentation on solar cooking after dinner. It was a full meal including appetizers, main course, ...

I am ordering two of the double boilers because I want to run some tests where I use identical pots i ...

It is possible to build a 16 sided triple angled cooker. However, depending upon the size of the cooker, it may not be necessary to go from a double to a triple cooker. For example, the 0.8 meter do ...

Can you say something about why the dimensions are so precise? Your arcs are accurate to a hundredth of a degree (i.e. less than an arc minute) which seems unlikely to be achievable outside a sophisti ...

Does anyone know a source for bright aluminum refelctor material for solar cooker construction such as that used for the reflectors on the Sun Oven? Preferably in the US.

Hi MARC
You are absolutely right when you say that our cooker needs a stand to hold the cooker and the pot. Moving the pot to the mouth of the cooker makes the cooker more efficient, but the pot mus ...

We have revised the drawings of the cooker cone on our web site. This should make them easier to understand and use. The drawing of the cone layout has been revised and a new drawing of one of the t ...
