Here is the link to what I have. www.sunoven.com As I stated it folds down
compactly doesn't really take up much space when set up. All I need to
develop is a good automatic solar powered sun tracker and I'll have it made.
Looking at your design I'm rather amazed that it didn't incinerate anything
placed at the focal point. I would think that wind and lack of heat
retention may have prevented from reaching boiling or beyond. I have seen
parabolic designs that are "scary" hot. I understand that SCT's will do the
same if pointed at the sun in an unfiltered state. The "smoke" shot of the
rays is awesome..

Jimmy, that's amazing that you can boil water with something that size.
Does it use a concentration system to get that hot? I ask, because my
attempt to boil water with the Sun fell a few degrees short of the goal. To
see my DIY attempt at solar cooking, check out:

At least it worked out well for cooking hotdogs. :) And how about that
cool image showing the rays of light getting concentrated?
