Cookkit

In the year 1999, another very interesting but very simple and effective design, a very low cost solar cooker was presented by Prof. Roger Bernard (1995) of France.
Brand named CooKit, it is just a packet of interconnected reflectors.
When open, they fold out into a small bracket of reflectors around a central space where a cooking vessel is kept in a transparent container of a heat resistant plastic.
The cooker, probably the simplest among the lot, is cheaper than that of the VITA design, works well, and is one of the most popular solar cookers on the planet.
