I need a half dish for a project and I decided to try the cone method to design the parabolic dish. Luck made the design fit a 4 by 8 sheet of corrugated plastic with almost no waste. (Full parabol ...

http://solarcooking.wikia.com/wiki/Solar_design_T-Square I tried to get a better idea of the shapes involved by using little mirrors stuck in mud to represent the reflector.

Box cookers are slow but reliable and can be unattended.

I am glad it works, hopefully it works in the oven too. (My pressure cooker loses a tiny bit of steam round the rubber seal.)
I admire your inventiveness.
Well done.

I think you could check out the clock based dripper tracker, 2 parabolic troughs to make a point focus, water clock dripper trackers and the kyoto trough idea. Also somethhing like the winston w dis ...

I put it in as the kyoto trough in the wiki but I do not know how to put it in the designs section of the ...

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 ...
