Hi, welcome to Solar Cooking! Thanks for your edit to the File:AIT Educooker3 (Aug 2008).jpg page.
basic solar box cooker plans
I am confused with this line : Glue aluminum foil to the inside of both boxes and also to the "inside of the remaining top flaps of the outer box"
Shouldn't it read: the tops of the INNER box ?
The outer box doesn't have flaps and I have a solar cooker that I made years ago from different plans and the top of the flap of the inner box is covered with foil
- This is correct. When you cut the hole in the top of the larger box there is still some box left around the edges. Glue foil to the underside of this. 22.214.171.124 06:18, January 5, 2010 (UTC)
