For the first time in human history, the majority of the world?s inhabitants now reside in cities. Urban inhabitants are expected to account for a staggering 67% of the world?s population (6.3 billion people) by 2050 [1]. This enormous migration toward urban environments has brought with it a host of challenges related to sustainability, health, and development. Engineers, scientists, and policy makers must grapple with the daunting task of providing the next generation of urban citizens with such core necessities as clean water, energy, and air.
