In fact, many useful innovations, such as energy-generating building materials and zero-emissions transportation, already exist; they simply need to be made accessible to those who need them most. Devices like small-scale water-filtration systems, portable heart monitors, and low-cost tablet computers are already dramatically improving the lives of the world’s poorest citizens and helping to level the economic playing field.
其实，产能建材及零排放交通等众多有用的创新成果已经存在；要做的仅仅是向最需要的人推广它们。小型水过滤系统、便携式心脏监视器和低成本平板电脑等设备已经显著改善了世界最贫困民众的生活，并在一定程度上改善了经济竞争环境。
