Kyoto trough solar cooker mimics a parabolic dish without a thousand cuts!

Step 6 What it means to panel cooker design

Panel cookers are simple small solar cookers that are often made by folding cardboard. The cardboard is covered with reflective material and they are usually used with a cooking pot that is covered with an oven bag for insulation. They are the simplest of all solar cookers and they are effective but generally they do not reflect much light onto the cooking pot.
My software simulation tests suggest that a panel cooker with at least one "tail" in line with path of the sun could be significantly more effective at catching the light.
The key is to keep the tail in line with the path of the sun across the sky.
That might mean some sort of rollers needed under the panel so that it can swivel.
The boost in energy collection may make the extra effort worth it.
I include a picture for clarification.
