That's impressive, if you need to boost the power, look into making a parabolic reflector out of an old digital satellite dish.
Thanks for the tip. I was thinking about seeing how I can improve it after I do some testing. One thought was to put a ceramic tile at the base to help it retain heat. As it sits, the pots would be sitting on plywood.
OP could have a seperate cooking box and the parabolic reflectors aimed at it. this could make pizza.
Use a convex lens from an old rear projection TV Look up solar scorcher
Were you thinking in the means of replacing the top pane of glass with a convex lens?
Definately provide some type of thermal mass inside. It will carry heat through passing clouds and prevent large temp swings. Ceramic tiles would be a good upgrade.
