Solar cookers, there are four types I know of. I. Parrabolic Cooker, this is fast and can be rotated to the sun. We ran a commercial kitchen at an event in the Uk. This would boil water in 20 mins in the UK on a warm day. They are excellent for using a wok with yet do not work with cloud. 2. Solar oven, these are like boxes with fold out reflectors. Its a good option for cooking to use both, start with the parabolic and move onto the solar oven. Then there are solar bags which are very cheap to make essentially with the reflective material of windscreens. They are a cube and are ideal for air situations because they can be dropped from above and will not break. They take a good few hours to cook though. Then there is a similar very low cost reflective card version, (around 3 Euros) this works for about twelve uses. I do some low tech invention myself and if I was to give you a place that may be worth working from I would have to start with limitations of what wont work. The Oven and the parabolic are fine if they are situated mostly in one place, they both can bend or break. The card ones are too disposable in my view. So to "try and develop a cooker that is faster, more compact and convenient, to promote sustainable living." I would add to that robust too, somethign that could be designed to suit the needs, be cheap and yet be better than the existing solar bages using just fabric could be this... If you look online for solar cooking bags. Then copy the design yet instead of using just the reflective material, (available in Southall)us strips or triangles of thin aluminium or another thin refective metal, it could even be metal pieces sown into the fabric. This will speed up the standard solar design. From what I understand, nothing like that presently exists and it would be very compact being able to fold flat, whilst being quite flexible and robust. It would be convenient as they can be packed between other items and either delivered by hand or dropped from the air and they would be faster to use than the existing design, although slightly more costly, at a guess they could cost in production about 7 Euros each. Hope that helps.
