I recently made a compound parabolic solar cooker. It has been working pretty well and i thought you might be interested.
I have a video showing how i made it at

and a video that explains the optical advantages is at

My reflector is good for up to 3 hours of unattended cooking. But you can design them for 1, 2 hours or 4 hours either.
It is just under 1m2 and I use it to cook 7 liter pots of soil with turkey bag over it.
It cooks the soil up to over 90C which kills weed seeds and bugs and makes it safe for growing seedlings.
I set it up before I leave for work in the mornings and it cooks later in the day.
