Recently, the Golzer and I were jonesing for some homemade cookies, but realized we had no way to make them; thus, we decide that we needed to make a solar oven (real story: I have a ledge outside my window and I noticed it got a lot of son, and said to Golze I should make a solar oven and he was like let's do it, that's what we learn to do in architecture school). China may be one of the best places in the world to make a solar oven, essential all the parts we used to make it we could have gotten for free, although we did pay money for stuff, because we were to lazy to go walk and look for it.
Parts breakdown:
The styrofoam box we got from Jenny Lou's for free (downside it smells like fish, upside we get fish cookies)
The piece of glass on the top cost RMB 40 (however, the night before I was at a place that had old glass windows laying around that I could have taken for free)
The card board for the reflectors free (randomly asked some guy for a piece of cardboard)
Glue RMB 1
Aluminum foil around RMB 30 (unless you buy 200 sqft)
Extra pieces of styrofoam RMB 5 per half a kilo (this is like unnecessary and mostly for aesthetics, also you probably can find it for free).
We also got a mirror for free that we are still trying to figure out how to attach (more on that in the future)
So essential the only thing you need to pay for is the glue and the aluminum foil, the rest of the stuff can be found lying around various places in da Jing. And if you find the right nongmin cart driver you just might be able to get it all in one place.
If you came to this site to learn how to build a solar oven I am sorry, but we don't actually know how, as this thing is untested and like to cause a solar flare, but I can recommend this site that looks like it knows what it is doing.
Look for more exciting post on our solar oven project and stay tuned to find out if our cookies taste like fish.
