Kyoto trough solar cooker mimics a parabolic dish without a thousand cuts!



Not even 1 vote in the us of efficiency competition! I guess presentation IS everything. Best of luck with it. Brian http:www.youtube.com/watch?v=qXVfGFQpYD8 shows my first prototype 15th may 2009 Well, it has been a busy 25 days.! I thought up this solar cooker, april 20 2009 in a eureka moment. This came from seeing the results of software tests on various different reflective dishes in the art of illusion software. They were simply not as good over time as I had hoped. And the problem as I see it is that simply revolving a shape round a center point is just plain wrong. The Kyoto Trough is already on solarcooking dot org as a new design! I had a free 8 ft by 4 ft corrugated sign and I used it for the main trough of the solar cooker. The plan is to design a highly effective solar cooker that is very cheap to make , does not need to be moved much and maximizes the return on materials used in making the solar cooker. I have uploaded the most recent art of illusion scene file here thirdcombined troughblabla.aoi If you download it, it might change the file extension to .temp. Just change it back to .aoi and it will work just fine when you open it in art of illusion! The file just happens to contain a parabolic dish, winston curve dish, and various others too. And all in 11kbytes! I am not good with art of illusion but it certainly helped me come up with this design. Brian

step 1Concentrating sunlight with 2 troughs (why it works)

You can concentrate sunlight to a point of light as shown by a Swedish guy over 30 years ago! Here is one of his videos of how it works. http:www.youtube.com/watch?v=FYz…

step 2Theory and practice (not quite the same thing)

My best ever solar cooker was a "compound parabolic solar cooker. It gave pretty good results comparable to commercial parabolics but the process to make it was too invo…

step 3

step 4Simplification! Why I went for the combined trough design.

I have made parabolic and compound parabolic dishes in the past. It is not exactly easy! But I thought that when I showed my compound parabolic dish design to the world,(w…

step 5Why do 2 troughs work to concentrate light?

step 6Making the curves for the solar cooker.

LOW TECH and why. I use homemade tee square and a piece of string to make my parabolic curves. I try out the curves on a little table (too little but the biggest I ha…

step 7What it means to panel cooker design

Panel cookers are simple small solar cookers that are often made by folding cardboard. The cardboard is covered with reflective material and they are usually used with a c…

step 8The future for the Kyoto Trough?

WELL, I thought It might get a vote or 2 in the US of efficiency contest! But whatever. People will realize that the Swedish guy saw a parabolic dish and split it into 2 …

step 9Credits

No work is original! First of all, a big thanks to the people at the art of illusion forums on sourceforge and also a big thanks to the guy from Sweden who dreamed up a par…

step 10Recent devellopments with the experiment

May 16th, I did another test today but too many clouds. So thats it, time is up! US of efficiency competition is over and no votes again. Once templates are done, this …
