scientists can take carbon dioxide from the atmosphere and convert it into super-strong carbon nanofibers for use in manufacturing. If we can do this at scale—powered by solar—a system 10 percent the size of the Sahara Desert could reduce CO2 in the atmosphere to pre-industrial levels in about a decade. The applications are endless. And coming fast. Over the next decade, the impact of the very, very small is about to get very, very large.
