This is the kind of technology I really enjoy writing about and like to see coming out of brilliant young minds. What I didn't write in the story but maybe should've mentioned is that Harvard students came up with the idea, but it was a push from Bill Clinton, who heard about it from one of the inventors when she spoke at something he sponsored, who pushed them to commercialize it. I'm glad he did. We really need people thinking like this to help make positive changes in the world. What we take for granted could really mean a lot to someone who is not as advantaged.
