Cardboard box oven
This extremely simple invention fulfills all three categories of what makes innovation worthwhile in my mind, it saves money, it saves people, and it saves the environment. What more could one want?
While there is nothing gendered about this technology in and of itself, it holds the possibility for positive change, particularly for women. Often times, the women are the family members who have to gather wood to use for cooking. If this invention works in the field, and can be widespread, maybe women won’t have to spend so much time looking for wood, and devote their time to other tasks.
Also, what does it mean that this solar oven (not an entirely new concept at all) was developed by a man who lives in a place where there is really no need for cardboard box ovens?
