Introduction: Cooked Sun

Picture of Cooked Sun

Two bowls, one in plastic or hardened glass for water, and one in stainless steel or cast iron for water. The water in the upper bowl works as a magnifying glass onto the water in the lower bowl, bringing it to a boil as soon as the sun shines.

With a stand of separate metal rods to keep the upper bowl positioned above the lower bowl, and the lower bowl having a flat bottom, no other parts are needed to cook a nice soup or boil some veggies, and by keeping the metal rods detachable, the whole set is easy to put away in a backpack or in the kitchen cupboard after use.

(Note: changed the name from Sun Chef to Cooked Sun after I looked around on the Internet and found another type of invention using this name. Sorry for any confusion ocurring there!)

This is a really smart design! Did you find this somewhere or did you come up with it yourself? I would love to read more about it.

Hey thanks :)
My inspiration for the construction and to make use of the solar/water prism combination for cooking/heating water, came from a YouTube video:,
Although this Cooked Sun idea does feel so basic in a way so I can't imagine it not already being put into practice since years ago in many places, hence probably not making it my unique and first-ever idea :)
But then again, I haven't seen it anywhere before myself, so maybe I got lucky with this one?

Thanks for the comments, guys :)

We've had a great amount of sunshine here these last few days, and I simply took one glass bowl, app. 20 cm across, with a round bottom, and poured some water in it. I put it on a temporary stand of brick stones, allowing the sun to shine down through and below the bowl and the water.

It turned out that a focal point was created, and when I placed a small piece of dry wood where the light was brightest, it took about 30 seconds before it started to smoke.

It simply works as a magnifyer glass, so boiling water or lighting fires is a piece of cake with just a glass bowl and some water (and some sunshine!) :)

Just curious if anyone has attempted this yet?

Cool idea. You should build one and post the results.
