I like the idea, mainly because its such a big domain and a hard problem. I don't feel however that you should find a cofounder this way. Since this is such a tough domain to begin with, meeting someone and then starting a business together within days is setting yourself up for failure. The idea of changing the world is cool, and may be able to bind people together for the immediate short term, but what happens when you hit the really bad lows in the startup? You haven't known each other for very long, and may split. That being said, I'm sure you have already thought about that, and are ready for that risk. If you are, then god speed and I really do hope you can change the world.
