K. Eric Drexler

K. Eric Drexler

Kim Eric Drexler (born April 25, 1955 in Oakland, California) is an American engineer best known for popularizing the potential of molecular nanotechnology (MNT), from the 1970s and 1980s.His 1991 doctoral thesis at MIT was revised and published asthe book " [http://www.e-drexler.com/d/06/00/Nanosystems/toc.html "Nanosystems Molecular Machinery Manufacturing and Computation"] " (1992), which received the Association of American Publishers award for Best Computer Science Book of 1992. He also coined the term grey goo.

Life and work

K. Eric Drexler was very strongly influenced by ideas on Limits to Growth in the early 1970s. His response in his first year at Massachusetts Institute of Technology was to seek out someone who was working on extraterrestrial resources. He found Dr. Gerard K. O'Neill of Princeton University, a physicist famous for a strong focus on particle accelerators and his landmark work on the concepts of space colonization. Drexler was involved in NASA summer studies in 1975 and 1976. Besides working summers for O'Neill building mass driver prototypes, he delivered papers at the first three Space Manufacturing conferences at Princeton. The 1977 and 1979 papers were co-authored with Keith Henson, and patents were issued on both subjects, vapor phase fabrication and space radiators.

Drexler participated in NASA summer studies on space colonies in 1975 and 1976. He fabricated metal films a few tens of nanometers thick on a wax support to demonstrate the potentials of high performance solar sails. He was active in space politics, helping the L5 Society defeat the Moon Treaty in 1980.

During the late 1970s, he began to develop ideas about molecular nanotechnology (MNT). In 1979, Drexler encountered Richard Feynman's provocative 1959 talk There's Plenty of Room at the Bottom. The term nanotechnology was coined by the Tokyo Science University Professor Norio Taniguchi in 1974 to describe the precision manufacture of materials with nanometer tolerances, and was unknowingly appropriated by Drexler in his 1986 book "" to describe what later became known as molecular nanotechnology (MNT). In that book, he proposed the idea of a nanoscale "assembler" which would be able to build a copy of itself and of other items of arbitrary complexity. He also first published the term "grey goo" to describe what might happen if a hypothetical self-replicating molecular nanotechnology went out of control.

Drexler holds three degrees from MIT [http://alum.mit.edu] . He received his S.B. in Interdisciplinary Sciences in 1977 and his S.M. in 1979 in Astro/Aerospace Engineering with a Master's thesis titled [http://dspace.mit.edu/bitstream/1721.1/16234/1/06483741.pdf "Design of a High Performance Solar Sail System,."] In 1991 he earned a Ph.D. under the auspices of the MIT Media Lab (formally, the Media Arts and Sciences Section, School of Architecture and Planning). His Ph.D. work was the first doctoral degree on the topic of molecular nanotechnology and (after some editing) his thesis, [http://dspace.mit.edu/bitstream/1721.1/27999/1/25696817.pdf "Molecular Machinery and Manufacturing with Applications to Computation,"] was published as "Nanosystems: Molecular Machinery, Manufacturing and Computation" (1992), which received the Association of American Publishers award for Best Computer Science Book of 1992.

Drexler and Christine Peterson, at that time husband and wife, founded the Foresight Institute in 1986 with the mission of "Preparing for nanotechnology.” Drexler and Peterson ended their 21-year marriage in 2002. Drexler is no longer a member of the Foresight Institute.

In August 2005 Drexler joined Nanorex, a molecular engineering software company based in Bloomfield Hills, Michigan, to serve as the company's Chief Technical Advisor. [http://www.nanoengineer-1.com/mambo/] [http://www.nanoengineer-1.com/mambo/index.php?option=com_content&task=view&id=69&Itemid=73] Nanorex's nanoENGINEER-1 software was reportedly able to simulate a hypothetical differential gear design in "a snap". According to Nanorex's web site, an open source molecular design program is currently slated for release in Fall 2007.

In 2006, Drexler married Rosa Wang, a former investment banker who works with on improving the social capital markets.


Drexler's work on nanotechnology was criticized as naive by Nobel Prize winner Richard Smalley in a 2001 "Scientific American" article. Smalley first argued that "fat fingers" made MNT impossible. He later argued that nanomachines would have to resemble chemical enzymes more than Drexler's assemblers and could only work in water. Drexler maintained that both were straw man arguments, and in the case of enzymes, Prof. Klibanov wrote in 1994, "...using an enzyme in organic solvents eliminates several obstacles. . . " [http://crnano.org/Debate.htm] ) Drexler had difficulty in getting Smalley to respond, but in December 2003, Chemical and Engineering news carried a 4 part debate. [http://pubs.acs.org/cen/coverstory/8148/8148counterpoint.html]

One of the barriers to achieving molecular nanotechnology is the lack of an efficient way to create machines on a molecular/atomic scale. One of Drexler's early ideas was an "assembler," a nanomachine that would comprise an arm and a computer that could be programmed to build more nanomachines. If an assembler could be built, it might then build a copy of itself, and thus potentially be useful for efficient mass production of nanomachines. But the lack of a way to first build an assembler remains the "sine qua non" obstacle to achieving this vision.

A second difficulty in reaching molecular nanotechnology is design. Hand design of a gear or bearing at the level of atoms is a gruelling task. While Drexler, Merkle and others have created a few designs of simple parts, no comprehensive design effort for anything approaching the complexity of a Model T Ford has been attempted.

A third difficulty in achieving molecular technology is separating successful trials from failures, and elucidating the failure mechanisms of the failures. Unlike Darwinian evolution, which proceeds by random variations in ensembles of organisms combined with deterministic reproduction/extinction as a selection process to achieve great complexity after billions of years (a set of mechanisms that Richard Dawkins has referred to as a "blind watchmaker"), deliberate design and building of nanoscale mechanisms requires a means other than reproduction/extinction to winnow successes from failures. Such means are difficult to provide (and presently non-existent) for anything other than small assemblages of atoms viewable by an AFM or STM.

Thus, even in the latest report [http://www.nap.edu/catalog/11752.html A Matter of Size: Triennial Review of the National Nanotechnology Initiative] put out by the National Academies Press in December 2006, (roughly twenty years after "Engines of Creation" was published) no clear way forward toward molecular nanotechnology is seen, as per the conclusion on page 108 of that report: "Although theoretical calculations can be made today, the eventually attainablerange of chemical reaction cycles, error rates, speed of operation, and thermodynamicefficiencies of such bottom-up manufacturing systems cannot be reliablypredicted at this time. Thus, the eventually attainable perfection and complexity ofmanufactured products, while they can be calculated in theory, cannot be predictedwith confidence. Finally, the optimum research paths that might lead to systemswhich greatly exceed the thermodynamic efficiencies and other capabilities ofbiological systems cannot be reliably predicted at this time. Research funding thatis based on the ability of investigators to produce experimental demonstrationsthat link to abstract models and guide long-term vision is most appropriate toachieve this goal."

In science fiction

Drexler is mentioned in the science fiction book "The Diamond Age" as one of the heroes of a future world where nanotechnology is ubiquitous.

In the science fiction novel "Newton's Wake" by Ken Macleod a 'drexler' is a nanotech assembler of pretty much anything that can fit in the volume of the particular machine - socks to starships.

Drexler is also mentioned in the science fiction book "Decipher" by Stel Pavlou, his book is mentioned as one of the starting points of the nanomachine construction, as well as giving a better understanding of the way carbon 60 was to be applied.

James Rollins references Drexler's "Engines of Creation" in his novel "Excavation", using his theory of a molecular machine in two sections as a possible explanation for the mysterious "Substance Z" in the story.
