Alas, this nice idea, solar cardboard box ovens, has been tried in developing countries for 30+ years and has never really made an impact.
This is a new design, which hasn't been tried in developing countries. Are arguing that since it failed in the past that we should not try something new in the future? Solar cooking takes a long time. So does chopping wood, or scavenging for it. I believe that this new box design box has an automatic setting that allows the owner to do other things while food is cooking in the box. Cardboard cookers are very fragile. So it breaks every few months. At $5 each, it's probably cheaper than scarce wood; and you can burn the box. But when the other option is to get wood, one tends to take care of one's stuff. The sun doesn't always shine when people want to cook. So burn wood when the sun is not shining and use the box when it is shining. It's a hybrid!
