I believe the parent is referring to reflective solar stoves.  There is a picture of one in the article.  It&#x27;s basically just a parabolic mirror and you put the food at the focal point.<p>The article said that the village had such stoves, but the weren&#x27;t adopted for some reason.  I may have missed it (I was skimming), but it would be interesting to see why they weren&#x27;t adopted.  My guess: having to orient your cooking around the position of the sun.  Possibly the women do not have flexible enough time schedules to do it.
