You hear nanotechnology used more and more often these days - and it has made some impact in everyday life. But the real change and payoff will occur much further down the road when real molecular manufacturing is possible. Dr. Eric Drexler, author of Nanosystems: Molecular Machinery, Manufacturing, and Computation, has been pushing this field for twenty years, and it's finally starting to go mainstream. What Is Nanotechnology? A nanofactory is Dr. Drexler's concept for safe production of everyday objects from a desktop device that converts raw material molecules into finished products. In a matter of hours! Various predictions put the nanofactory in the 2020 to 2030 time-frame. Once the basic capability exists to build large objects - such as a hand-held computer - from molecules and atoms, we will be able to build anything we want to build. This changes how life will be lived more than anything since the printing press. How Will We Use Nanotechnology? For example: Your health...
