Good work Solar! As to finding ready data on the heat collected for a specific oven, I think the commercial manufacturers play those cards close to the vest as they are in competition with one-another.
Because so many variables affect the temperature of any solar oven, such as surface area of reflector, type of reflecting material, cleanliness of reflector, hours & intensity of sunlight available, size of receiver, material of receiver, contents of receiver, insulation of receiver, ambient air temp, etc., I expect the type of experimentation you have started is the best source for developing a rough range of expected temperatures.
Please by all means continue posting your measurements as you have them.

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.

Share the love!
