ORNL Site Discusses
Laser-Driven Motor and Nanotechnology Piston Concepts

The research team of Dr. Don W. Noid, Dr. Bobby G. Sumpter and Robert Tuzun at Oak Ridge National Laboratory have posted their work on a Nanotechnology Laser-Driven Motor (by all three researchers) and Nanotechnology Pistons (Noid and Sumpter) on the Web at http://www.ccs.ornl.gov/GC/ornl/Nano96.html. The site includes an illustration of the graphite nanoscale motor, a 3.7 megabyte MPEG animation of the motor's performance, and discussion of design concepts. The Nanotechnology Pistons page includes several illustrations, including a closeup of a buckeyball interrupting flow of helium atoms in a graphite nanotube and several views of a simple nano-piston.

Engines of Creation on the Web

  Russel Whitaker, internal webmaster for Silicon Graphics, put Engines of Creation on the Web.

Thanks to Russell Whitaker (aided by earlier work of John Quel, John Cramer, and Jim Lewis), the full text of
Engines of Creation is now available on the Web at http://www.foresight.org/EOC/. A special introduction to this version has been provided by the author, Eric Drexler:

The ten years since Engines of Creation was first published have brought us far along the path to the development of molecular nanotechnology and molecular manufacturing. Advances have been faster than I had expected.

The basic concepts have also been more controversial than I had expected. Even now, after (for example) the US Science Advisor has called for the development of molecular manufacturing, segments of the science establishment are still having difficulties with some quite simple ideas.

It seems obvious that gaining thorough control of matter at the molecular level will enable major technological advances, and our progress toward this ability is likewise obvious. The molecular machinery found in nature provides an existence proof for enormous capabilities. Research advances in building such machines are reported in journals every week. Perhaps the short time horizons common in US and European science provide the excuse for neglecting the consequences of what we already know to be possible.

Engines of Creation projected the development of hypertext publishing systems; now it is at last appearing on one. While the Web lacks several important features, it nonetheless provides many of the benefits described in Engines.

It's gratifying to see Engines made available in this new medium. My thanks to Russell Whitaker for putting it into html, and to John Quel, John Cramer, and Jim Lewis for scanning in the text for an earlier HyperCard version.

There's not much I'd change in Engines if rewritten today (that is, I'd fiddle all the details and make it worse, but change little of the substance). The technological work keeps evolving and expanding in scope and analytical detail, but the basic concepts have survived critical examination, on the net and elsewhere.

To keep in touch with developments in nanotechnology, contact Foresight Institute or see Foresight's Web site [http://www.foresight.org] and the Institute for Molecular Manufacturing site http://www.imm.org now under development.

NASA Ames Hosts Workshop on Computational Nanotechnology

The Numerical Aerodynamic Simulation (NAS) Systems Division at NASA Ames Research Center sponsored a two-day workshop on computational molecular nanotechnology in March. Participants included scientists and engineers from academia, industry, and government. Technical presentations described current state-of-the-art computer simulations and future requirements for computational nanotechnology applications. Discussion sessions explored possibilities for joint research work in this area involving NASA scientists and facilities.

"The development of nanotechnology will require massive amounts of computation and the most powerful computers available will be required, including the teraflop/second and even petaflop/second systems of the future," said event organizer Al Globus of MRJ at NASA. "Even today, simulations on high performance computer systems can be used in conjunction with laboratory demonstrations to point the way to the most promising paths of nanotechnology development."

"Although massive computations will be required, they will not be enough. Substantial algorithm, database, user interface, and visualization work will be required to meet the challenges of computational nanotechnology. Entirely new software concepts may be required to realize the promise of molecular nanotechnology."

Every field needs a key goal, Globus said. "Physics has the unified field theory and computer graphics has had reproducing the visual world we live in. What should computational nanotechnology's goal be?" Globus asked participants in one session. Suggested candidates included:

  • Molecular manufacturing CAD
  • Replicator/assembler or other nano-robot (the consensus choice of participants)
  • Predict and design self-assembly (and determine the free energy)
  • Principles of molecular design
  • Accurate force fields for nanotechnology systems
  • Accurate simulations of large systems and long time scales (integrated nano, meso, macro scale simulations)
  • Properties and performance at the nano-scale
  • Nano-robots building computer circuits
  • Medical applications
  • Nano-spacecraft
  • Terraforming using nanotechnology

It was also mentioned that safety is a major issue and should be addressed early on.

Speakers (a partial list) included Ralph Merke of Xerox, speaking on his concept of a simple assembler, Don Brenner of North Carolina State University on Nanoscale Engineering, Donovan Chin of Harvard University on "Computational and Physical-Organic Approaches Towards Nanotechnology," William Goddard of Caltech on "Molecular Dynamics Simulations in Nanotechnology," Gustavo E. Scuseria of the Center for Nanoscale Science and Technology and Chemistry Department at Rice University on "Electronic Structures Tools for Computational Nanotechnology" and Robert Tuzun of Oak Ridge National Laboratory, on the work of Tuzun and his colleague on "Molecular Dynamics Simulation of Nanomachine Components."

A more complete report on the conference is available on the Web at http://www.nas.nasa.gov/NAS/Projects/nanotechnology/workshop/

Two Texas Presentations on Molecular Nanotechnology

Roger Duncan made a presentation on molecular nanotechnology to the Sustainable Energy Development Council (SEDC). The SEDC was created by Texas Governor Ann Richards to write a plan for the development of renewable energy and energy efficiency for Texas. Nanotechnology was included in the group's final plan, both as a goal and an objective.

Duncan also made a presentation to the Urban Consortium, a group of representatives from the 50 largest cities in the U.S., formed as a committee of Public Technology Inc. PTI has asked Duncan to write a short article for their publication to gauge the level of interest in the subject among municipal leaders. Duncan seeks input from Foresight members on the impact of nanotechnology on municipal planning being done within the next ten years.

European Nanotechnology Initiative Conference Followup

Update 24 reported plans for a European Nanotechnology Initiative (ENI) Conference April 9-11 in Copenhagen. The event organizers, BioSoft, report 45 participants attended, who concluded that "if we fail to invest in the European research in nanotechnology, we invite foreign dominance of this strategic technology as previously experienced in the microtechnologies. One crucial activity in the next few years will be to develop new tools that permit observation and manipulation of nano sized objects." A number of organizations in Europe are "positioned to play a strong role in this field provided that nanotechnology in general obtains the requested support," the final report said.

Following the conference, organizers presented the group's findings to the European Union Parliament on April 22. They described the potentials of nanotechnology, sought funding, and proposed the creation of Ph.D. or post-doctoral nanotechnology programs. Organizers are now seeking to formalize the structure of the group brought together for the conference, and to create a Web site to facilitate exchange of information.
