I will do a better drawing soon. Basically you have a large compound parabolic trough to concentrate the light to an area below the focal point. (Rotate the right hand side of a parabolic dish 30 degrees anticlockwise to get the 30 degree compound parabolic shape) which is good for 2 hours of cooking. The 2 v shaped wings concentrate the light further onto the cooking vessel in the middle. The primary big reflector must be in line with the direction that the sun travels. If you make a panel cooker with this method, you should be able to "grab" more light than a conventional panel cooker.
There has been almost no interest in my "software for solar design" idea.
This solar cooker design comes from using that software.
Please do not dismiss it out of hand.
Anyone want to try it?

Can you add a short article about this in the Solar Cooking Archive Wiki?

Thanks,

Thanks Tom,
But I have not made one yet!
And I have not tested it in art of illusion yet either. (I am not good with software).
I just put it out there in case a bus hits me tomorrow. Seems like a good idea that just might work.

Tried a rough mock up in art of illusion and it seemed ok. It is on youtube at

Thanks! To add it to the designs, I just added this category at the bottom:
Solar cooker designs

I'll embedd the video. You do this by clicking the embed video tool just above the text box when you're editing an article in the wiki.

I finally made one and it seems to work ok.

(I got it finished at 5 pm with high clouds overhead and I gave it a go heating up a 1 kg aluminum pot. It got to 80C inside the pot in 10 minutes without a turkey bag to keep in the heat. I might get more tests done tomorrow.
