I am a college professor and I am working with a Non Profit - Kids Cafe - that prepares healthy meals for school kids in underprivileged areas 3 nights a week. They now feed several hundred kids a week.  The problem is establishing a sustainable source of funding for the effort.  This is the problem that my class is working on.  The person who has run kid's cafe has researched the idea of selling food from a cart - a healthy hot dog stand - or something that could be easily prepared and dispensed from a cart.  Having seen your TED speech - I was wondering if you have any suggestions on how we could help him fulfill this vision? He is not talking about a small cart - he has found some high end carts - that are almost like a small diner.  Any help you can give would be greatly appreciated.
