Totally, assuming you're able to situate the wok in the middle of the New Mexico desert, and are satisfied with the safety profile of not putting your hand near

Totally, assuming you're able to situate the wok in the middle of the New Mexico desert, and are satisfied with the safety profile of not putting your hand near it lest it become part of the dish.

The sun is the same temperature no matter where you are on earth, so you could reach 900 degrees regardless of where you are, as long as you can see the sun. You would just need to make the reflectors larger as you got farther north.

I remember as a kid, in India, solar, gobar/bio gas and alternative ways of cooking and heating were all the rage. Then liquified petroleum gas became cheaper and everything just died. Here’s[1] an example of what I’m talking about. It was mostly for rural areas without reliable ways of delivering cooking fuels.

  Oh wow I vividly remember in the second grade there's a story of grandma cooking noodles using a solar cooker (it was in the Chinese textbook for Mainland China circa 1998). Searching for a couple keywords on Taobao and apparently you can still buy those things. E.g. https://www.taobao.com/list/item/wap/595475929092.htm https://www.taobao.com/list/item/wap/595475929092.htm

  ah it's gobar gas, I kept searching for bogar gas in futility just like 2 days ago from an idea an Indian colleague of mine shared with me some 10 years ago. Seems like bio-gas has become the preferred term for this technique.

  I'm a native (American) English speaker and with a quick search of my 15 year old reddit account comments, I can guarantee you that native speakers would use "situate" just like that.

  You... don't think I'm a native English speaker? My guy, I was born in Canada, of British descent and live in San Francisco. I was just being highfalutin. And to head that one off, it was a self-referential joke. Technically English is my second language, but I don't think that plays into it these days.

If there's enough sunlight to grow chiles locally in the region, there'll be enough sunlight to use this approach. Chiles won't really grow that well without good daily sunlight and relatively warm temperatures.

  Your range is cooking primarily through conduction though, it only heats what it touches. This is heating through direct electromagnetic radiation, if anything gets in the sun beam it will fry at 900 degrees. Move your hand in the wrong place and you will have massive burns in an instant without touching anything.

    At the Sandia central collector the main beam is much hotter than 900 degrees and it's not uncommon for birds to be cooked instantly and drop from the sky if they happen to fly too close to the beam's focal point. This is one reason why the heliostats are always kept defocused unless an experiment is taking place.
