>What's the thing on the lower right picture for?

The smaller box? It is a bread riser. I was using it while setting things up and taking pics. I don't need it when doing 1-2 loaves because I can use the main solar cooker to raise bread when its reflectors are not attached.

>What are the reflective surfaces made of?
>Would cardboard with aluminium foil on top suffice for such a device?

1/4" plywood (luan board) with aluminum foil (shiny side up). I used a mixture of half water and half wood glue to glue the foil to the board. You can also use cardboard. Most of my cookers used cardboard. You can patch pieces of cardboard together with the same glue to make larger panels.

>How much would the efficiency of the cooker suffer if you removed the glass?

It might reach 150F with the glass off. A single pane of glass is prone to wind. A double panes of glass is the best. Make sure to use tempered glass on the inside pane or it will shatter. Without the glass, it would be a simple panel cooker ( http://www.wikihow.com/Build-a-Solar-Panel-Cooker ).

>And can you estimate how much the size of the model in your picture could be reduced if the required peak temperature was only around 200F?

On a sunny day, just about anything that traps heat with even a single small reflector will get to 200F easily. The more reflector space you have the faster it will get there and the hotter it will be. The more insulation you use the better.

Solar cookers are super simple to make and use. The only slightly difficult part is getting high temps in a short amount of time. When in doubt, add more reflector space and more insulation.

>I'm always glad when he reposts pics

I really need to finish some of my other cookers and take new photos.
