What are the distinctive features of the Papillon?

The solar cooker type "Bamako" introduced in Bukina Faso in the nineties, did not fully satisfy the expectations of women. They wanted in particular:  

	The cooker should be able to cope with cooking vessels of up to 20 litres.
	Access to the cooking vessel should be facilitated;
	Soiling of reflector surfaces by overspill from the pot should be impossible.
	The relation between output and price should be improved.

The concept consists of the following features:

	Two reflectors, each which has a surface of 1sqm; the wings can be folded upwards when the cooker is not used, allowing easy passage through a 70 cm  wide door;
	The supporting structure has two wheels for transport;
	Due to the geometry of the wings, heating goes nearly exclusively to the bottom of the pot;
	The cook has direct access to the cooking place from behind;
	There are no reflecting surfaces in front of the cooks eyes that could cause dazzling;
	There are no reflector sheets under the pot. Thus overspill is avoided.
