Molecular Manufacturing: What, Why and How
Nanotech: Moving Closer to a Manufacturing Revolution
New York, NY | May 17, 2005
Nanotechnology's long-expected transformation of manufacturing has just moved closer to reality. A new analysis of existing technological capabilities, including proposed steps from today's nanotech to advanced molecular machine systems, was released today by the Center for Responsible Nanotechnology.
The study, "Molecular Manufacturing: What, Why and How," performed by Chris Phoenix, CRN Director of Research, is available online at Wise-Nano.org. It shows how existing technologies can be coordinated toward a reachable goal of general-purpose molecular manufacturing.
"Molecular manufacturing offers a fundamentally new approach to build things 'from the bottom up'," said Phoenix. "The idea is to use nanoscale machines to create structures with atomic precision. Ultimately, that can result in the ability to make complex products, both small and large, with unprecedented performance and value."
Theories and concepts for molecular manufacturing, first proposed in the 1980's by nanotechnology pioneer K. Eric Drexler, have improved steadily since then. But recent progress is occurring at a faster pace. Less than two years ago, Phoenix published the first detailed architecture for a "nanofactory," a remarkably powerful general-purpose manufacturing appliance that could sit on a desktop. Since then, Drexler, working with John Burch, has developed an improved design that should be significantly more efficient.
Recent developments in DNA synthesis and polymer construction, plus advances in miniaturization and precision of scanning probe microscopes, are rapidly adding pieces to the nanotech jigsaw puzzle.
This new study puts the pieces in place. Presenting research performed by CRN under a grant from NASA's Institute for Advanced Concepts, while also updating and combining existing work in related fields, it describes a newly simplified way to develop molecular manufacturing starting with today's technology.
Phoenix describes two approaches for building the initial basic tools with current technology. Other sections outline incremental improvement from those early tools toward the first integrated nanofactory, and analyze a scalable architecture for a more advanced nanofactory. Product performance and likely applications are discussed, as well as incentives for corporate or government investment in the technology. Finally, considerations and recommendations for a targeted development program are presented.
"We've done an end-to-end analysis of molecular manufacturing's goals as well as some ways to get there," said Phoenix. "More important, this study shows that development of the technology will be both highly desirable and relatively straightforward. It's probably not as far away as many people think, which means it's time to begin discussing the ramifications, both positive and negative."
"Molecular Manufacturing: What, Why and How" does not directly address the societal, environmental, medical, economic, military, security, and geopolitical implications of the technology's introduction. However, those topics are explored in other papers and articles on CRN’s website.
