The New African Stove

I have never seen one of these before . . . that is a big pot of onions simmering away and heated solely by the sun's rays focused by this apparatus.   Not sure what it costs but it must have a role in Africa and saves/would save a quite a few back breaking trips to the woods to cut and carry back logs . . . see this blip by dcafrica . . . https://www.blipfoto.com/entry/2081099542064794328
