I see this a lot. An innovative idea with amazing societal benefits and a fantastic technical solution. But there are some fundamental questions that any potential business partner -- including investors -- would need answering. For example;

> What problem are you actually solving -- really?

> How will the business make money and what is the size of the market?

> Do you have interest from those who would actually pay for the solution?

> What are the main obstacles to implementation -- does this require huge strucural change to established governments?

There's a longer list of questions but you get the picture. This is a crucial stage and it requires harsh introspection and brutal honesty. It seems like you've done a great job selling the dream (to the users), now you need to understand and sell the reality (to the payers). Personally, I love the idea. Good luck!
