Introduction

The solar design t-square is a simple physical device that models the sun passing over a new solar reflector design. Using clay and "stop motion" changes to little mirrors, I made successful models and a full size Clam shaped reflector for 2 hours of unattended solar cooking. At full power! Solardesigntsquare.jpg I believe it could be used to design better panel cookers than any that exist today in about 4 hours. So you could have reflectors designed specifically for 1 hour unattended cooking, 1.5 hours or 2 hours, depending on what is needed. I used cheap laser pointers in my first solar design t-square but I do not recommend this. The barrel of the pointers are NOT in line with the laser. so it is very fiddley to get them right. Use a small laser level instead. I designed models first and then scaled them up. Perhaps now that we know the rough shape, you could try make a full size reflector in one go. The following diagram shows (I hope) why secondary reflectors are needed. Secondarysmall.jpg Brian
