Poly-Furnace

The Poly-furnace is a plastic model of the Cookit made by Solar Cookers International.  Because of the adverse living conditions of the refugees in Darfur, Sudan the cardboard Cookit will not last much more than 6 months to a year. The need to have a durable Cookit has prompted us to develop one made of plastic polyproplyene flute board. Reflective aluminum polyester is attached to the surface before it is cut and formed. A local group of volunteers have begun to make these for introduction into Sudan 2008.

Borma Water-Pot Cooker:

The Sun Scoop

The Sun Scoop is a box type cooker made of plastic flute board. It has been designed with Africa city dwelllers in mind. It is large enough for 4 pots, and yet light enough to pack up like a suitcase and carry it.  The Sun Scoop has a simple glass door for a lid and inner tube for the seal. All these parts are replaceable with local materials if they happen to get broken. The Sun Scoop does not have to be tipped toward the sun or have any special level for the pots. It is designed to catch the sun rays from the horizion as well as those from overhead.
