I totally agree Darpan, most communities obviously cannot afford to build a structure at once however i think there might be room for creative financing options. For instance if a private entity is willing to front a family unit, residents can pay over time as they do through other mobile services. What i've seen with other services provided in our country is that if you offer it in small manageable monthly payments, they will subscribe. More thought required though, thank you!
Hi James - this is excellent. I'm a little late to the party but we are started a design challenge in Ghana as well focusing on low-cost isolation units (http://www.innovategh.blogspot.com) so i'm excited to see the pop-up tent design gain traction. i will be encouraging students to use the human centered design processes but since we cannot be there, we would love you and your teams feedback on the design criteria we should consider. Let us know if there are any additional areas you have not covered that you would like students to think about. Once our challenge is over here, we would be happy to share our ideas with you as well to see if any of them would be useful and or easy to implement. Keep up the good work!
