Gabriel Landowski I was trying think on how to help you to organize a proposal to send to IBM to develop your project, so I was thinking of your ideas and how you could break them down into different components, the "others" are the other ideas you had. I hope that this makes sense and is helpful :)
John Kiernan-Lewis taking things to scale can be tricky with the profit aspect going on (but I hope like you that companies make it happen and help people) -- how expensive and easy are these to make? Could people make them locally? It would be really interesting if they could because then they could even potentially integrate models of economic development where local groups make them and can trade or get rewards for producing and using them.
