Sun harvesting: Woman's solar oven sparks change in Migori village

It's noon on a sunny Monday. We meet Carolyn Olang at her rural home in Rairi Village, Migori County. She is preparing lunch after a long day of work weeding her farm.

I am expecting to see smoke and fire coming out of her kitchen but that is not the case. In front of her is a contraption constructed out of timber, an old blanket, aluminium foil and glass. It is painted black and is about the size of a large suitcase. This odd-looking box is the source of heat that Carolyn is using to cook vegetables.
