Dutching on the Web: Dutch Oven Solar Cooking?

I’m always looking for a new way to cook in a Dutch oven. I was cruising around YouTube tonight and I found this video. I was immediately intrigued by it. He’s using a big, square lens to focus the sunlight onto a dutch oven, to cook food in it.

When I saw the video, I was immediately skeptical, but also interested. I’m still not convinced just how effective it really is in cooking, but I can see that it can work for some dishes.

Here’s the video:

I think that if I were doing it, I would focus the light mostly on the side of the dutch oven, and I would rotate the oven a quarter turn every ten or fifteen minutes. I also noticed that he used an 8″ Dutch oven, which was nice and small. That means less food to heat, and less water to heat up as well. Each time the lid was lifted, it didn’t seem like there was boiling going on. Still, it got hot enough to cook the game hen.

It would be very interesting to try. Does anyone else reading this have any experience with solar cooking?
