I have checked the simple plan for the Cookit and found dimensions missing and misleading information. I can provide another better version!

Looking at the Manos Unidas variation... the numbers don't work for cutting the slit. The right triangle has sides of 14, 16, and 19(12+7) in the diagram. (a^2)+(b^2)=(c^2)... (14^2)+(16^2)=(19^2)... 452 =/= 361. Any suggestions or comments as to what it's supposed to be? Daniel Joseph, US Peace Corps, Philippines 13:45, April 3, 2012 (UTC+8)
Thanks, Daniel for alerting us to this. Can you upload a corrected version? We'd also like to learn more about your work in the Philippines with solar cookers. Tom Sponheim 18:47, April 3, 2012 (UTC)
The geometry of the measurements for cutting the slit in the following updated plan works out. I've used the measurements for an actual build and cooking performance seems good. The angle of the slit is about 47degrees. The CooKit plans have an angle of 61. Not sure how this affects the sun angle conditions under which the reflector operates optimally and overall efficiency. Will post information about my work here with solar cookers sometime soon. If this image looks good can someone more skilled at editing the wiki insert it on the article page? Thanks.
