This is really cool, and the effort is definitely admirable, but I'd have a few questions: 1. A suitcase can't conduct an examination and render a diagnosis; someone has to be able to operate it effectively. Are those people -- doctors, nurses, or someone with similar training -- available in the places that could benefit the most from this? 2. From what's been posted around here, India has a very serious basic sanitation problem. If that's true, two things: 2a. How will a predominantly filthy (bacterially speaking) environment effect the accuracy and utility of this, particularly over long term use of a single unit? 2b. Can we expect this to actually do any good in a significant number of cases? I'd expect that a diagnosis like "yes, your malady is x, which is an infection from the water you drink" is going to do very little good for many people's situation. I have no idea how the cost of this compares to salaries or publicly-available funds for the places this is intended for, but that seems to me like another potential issue.
