Dean Kamen is the guy. If you went back in time, stole Thomas Edison, assimilated him into our world, and told him to keep inventing, he would be Dean Kamen. From the Segway to the Coke machines with 100s of selections to fill your cup with (and hold up the god damn line!), Dean Kamen and his company Deka have invented a ton of things to make life on earth better. This is one of his most recent projects. A water purifyer that makes enough clean water to supply a village numbering in the hundreds all while using the energy of a hair dryer. This guy is amazing, seriously. We all need more Kamen in our lives.
