Each year, Technology Review selects what it believes are the 10 most important emerging technologies. The winners are chosen based on the editors’ coverage of key fields. The question that we ask is simple: is the technology likely to change the world? Some of these changes are on the largest scale possible: better biofuels, more efficient solar cells, and green concrete all aim at tackling global warming in the years ahead. Other changes will be more local and involve how we use technology: for example, 3-D screens on mobile devices, new applications for cloud computing, and social television. And new ways to implant medical electronics and develop drugs for diseases will affect us on the most intimate level of all, with the promise of making our lives healthier.
