	Grey goo - Wikipedia, the free encyclopedia
		In a worst-case scenario, all of the matter in the universe could be turned into goo (with "goo" meaning a large mass of replicating nanomachines lacking large-scale structure, which may or may not actually appear goo-like), killing the universe's inhabitants.
		Red Goo is goo unleashed intentionally by terrorists, a doomsday weapon, or a private individual who wishes to commit suicide with a bang.
		Thus a living goo could be a multicellular organism that obtains its raw materials to grow through ecophagy, and then grows through a process of exponential assembly such as cell division.

	Nanotechnology: Grey Goo is a Small Issue
		Fear of runaway nanobots, or “grey goo”, is more of a public issue than a scientific problem.
		This article and other recent fictional portrayals of grey goo, as well as statements by scientists such as Richard Smalley, are signs of significant public concern.
		But although biosphere-eating goo is a gripping story, current molecular manufacturing proposals contain nothing even similar to grey goo.

		Gray goo relies on very advanced versions of postulated atomic-precision robots capable of fine, very-high-frequency control over chemical reactions, and is thus theoretical possibility in the distant future.
		Deploying green goo targeted at human populations -- either specific races or our entire species in general -- would be, like the red fox virus program, a relatively simple and inexpensive biotech project, well within the capabilities of hundreds of biotech labs around the planet.
		Green goo might take many forms -- retrovirus, herpesvirus, RNA virus, DNA virus, protein virus (prion), etc. It might take the form of a humane, very effective sterility virus, or a cruder disease which destroys both the fertility and the health of the victim.

	6.3.1
		Although gray goo has essentially no military and no commercial value, and only limited terrorist value, it could be used as a tool for flmail.
		Cleaning up a single gray goo outbreak would be quite expensive and might require severe physical disruption of the area of the outbreak (atmospheric and oceanic goos [2909] deserve special concern for this reason).
		However, goo type systems do not appear to be ruled out by the laws of physics, and we cannot ignore the possibility that the five stated requirements could be combined deliberately at some point, in a device small enough that cleanup would be costly and difficult.

	ImmInst.org -> Gray Goo Is A Small Issue (Site not responding. Last check: 2007-10-26)
		Gray goo as a result of out of control nanotechnology played a starring role in an article titled "The Gray Goo Problem" by Lawrence Osborne in today's New York Times Magazine.
		This article and other recent fictional portrayals of gray goo, as well as statements by scientists such as Richard Smalley, are signs of significant public concern.
		A gray goo robot would also require a relatively large computer to store and process the full blueprint of such a complex device.

	gray goo - a Whatis.com definition
		Gray goo (or, in British spelling, "grey goo") is a term used to describe what life on our planet might become if
		The possibility of all of us becoming a lifeless conglomeration of gray goo, whether by accident or by robotic intent, is considered exceedingly unlikely.
		A significant argument against the possibility of a gray goo situation is that engineers should be able to build in limiting conditions for self-replication.

		He described there the "gray goo problem", where a simple accident with self-replicating nano-machines could mean the end of life on earth in a matter of days:
		Among the cognoscenti of nanotechnology, this threat has become known as the "gray goo problem." Though masses of uncontrolled replicators need not be gray or gooey, the term "gray goo" emphasizes that replicators able to obliterate life might be less inspiring than a single species of crabgrass.
		Gray goo would surely be a depressing ending to our human adventure on Earth, far worse than mere fire or ice, and one that could stem from a simple laboratory accident.

	NanoWiki: Editing GrayGoo (Site not responding. Last check: 2007-10-26)
		Gray goo is a hypothetical nanotechnological threat, believed by many to be an unlikely concern.
		The supposed result would be to convert the Earth's biosphere into a gray ocean of replicators, trying to consume one another as feedstock, with no humans, animals, plants, or bacteria remaining.
		The argument that gray goo is an unlikely threat is the difficulty of the design challenge.

	Will Gray Goo Devour Us All? (Site not responding. Last check: 2007-10-26)
		I don't think the "gray goo" scenario is credible or worth worrying about.
		From the absence of "green goo," I infer that the creation of gray goo is, if not impossible, at least extremely difficult and not worth worrying about at this juncture.
		For a nanotechnology researcher to worry about inventing gray goo is like worrying that while trying to invent gunpowder you will accidentally blow up the world.

	Word Spy - blue goo
		The nano-enthusiasts also occupied themselves considering whether such "gray goo" might be effectively countered by "blue goo," policebots that would form a nanotechnological immune system.
		Which it might: A possible solution to gray goo is blue goo: tiny self-replicating police robots that keep the other ones from misbehaving.
		There's golden goo, nanobots designed to extract gold from seawater; khaki goo, nanotechnology used for military purposes; and red goo, a collection of replicators designed to cause harm (a kind of nano-terrorism).

		Gray Goo refers to the obliteration of life that could result from the accidental and uncontrollable spread of self-replicating nanobots.
		To avoid a Gray Goo apocalypse, Drexler and his Foresight Institute, a non-profit organization whose purpose is to prepare society for the era of molecular nanotechnology (MNT), have established guidelines for developing "safe" MNT devices.
		Whitesides believes the most dangerous threat to the environment is not Gray Goo, but "self-catalyzing reactions," that is, chemical reactions that speed up and take place on their own, without the input of a chemist in a lab.28.

	Responsible Nanotechnology: The nano-Rorschach
		The article contrasting safe manufacturing vs. gray goo by myself and Eric Drexler is just a few days old, and already people are misinterpreting it.
		Gray goo is small floating self-contained inefficient devices that use biomass.
		Gray goo may be the reason why some scientists have fought so hard (with so little evidence) to avoid admitting that molecular manufacturing is possible.

	AlterNet: These Mortal Coils
		Mind you, the goo might not necessarily be gray in color, nor even gooey in texture.
		The idea of gray goo is a hypothetical worst-case scenario, dreamed up by people who think about such things.
		If gray goo is indeed within reach of humankind, then we couldn't prevent its production even if we wanted to.

	Cultural Gray Goo Sermon One: Harry Potter, Postmodernism, and Wicca
		He wrote of his concerns and used the phrase “gray goo” to describe the potential inundation and destruction of every living thing on planet earth as the result of the powerful combination of technologies of extreme miniaturization and biotechnology gone out of control.
		Drexler's “gray goo” warning deals with the physical world and the perceived potentials of raw technology.
		Cultural consensus is continually being reshaped by the gray goo.

	life beyond the gray goo
		Picture a future where the gray goo, in some form or other, quickly becomes the dominant form of matter in the universe.
		Within the gray goo, preserved like Barbarella within the Mathmos, vast intersecting parcels of personal space intersect; little bubbles of reality maintained artificially by an effervescant swirl of microscopic entities.
		Even though the whole universe is mostly just gray goo, or some analogy of it, the idea of living on a planet such as earth is something that's rooted in our immediate evolution.

	Nanobots,Gray Goo And Doomsday - Not To Worry (?)
		When I hear you say on air, that the "easiest" thing for nanotechies is the dreaded gray goo, well, you have been severely mislead.
		All I wished to report was that, from the standpoint of terrestrial science, gray goo is not even on long-range radar.
		Consequently, worries about 'gray goo' whilst very real GMO issues threaten us are thoroughly misplaced.

	Goo Systems
		I was decided on a (premium screen manufacturer) high-contrast screen, which is slightly gray instead of white.
		You have to take some care in applying the goo as it dries very fast and you have to ensure that you do not create any "banding".
		The image is brighter, the viewing angle is VERY wide, the colors are richer, and the light gray tint definitely does help with the fl level deficiencies of my LCD projector.

	Lifeboat Foundation FAQ
		Green goo and grey goo are similar threats and the same types of precautions and defenses apply to both.
		For simplicity, when we talk about "goo" dangers, we will just mention grey goo as it is a more established term than green goo or red goo.
		Blue goo is a group of nanotechnological machines that would monitor and control other machines to ensure that their replication does not get out of control.

	Some Limits to Global Ecophagy by Biovorous Nanoreplicators, with Public Policy Recomendations
		The gray plankton replicator waste heat signature is readily detected at an early stage.
		However, because the machines are solar powered, the active population of gray dust nanorobots is restricted to one optical depth of such devices.
		Each defensive nanorobot requires ~66 nN of motive force and ~6600 pW of onboard power to overcome drag loss [6] on the ~5.3 cm length of dragnet fiber that it is passing through the air at 0.1 m/sec.

	Grey Goo - An Exponentialist Explanation
		Grey goo (based on such assemblers) is the generic name given to a theoretical, and quite deadly, threat to all life.
		Each grey goo is a potentially deadly replication bomb, and could spread the "seeds" of other grey goos very quickly as described by Drexler.
		If you forget the dreaded grey goo scenario for a moment, and focus on the impact of nanotechnology on the future of the process of evolution for Earth species, you might see that grey goo is not really the threat.

	Green Goo: The New Nano-Threat
		First it was "gray goo," the threat of self-replicating machines populating the planet.
		Now an environmental think tank is raising the specter of "green goo," where biology is used to create new materials and new artificial life forms.
		In its report, published on July 8, the Action Group on Erosion, Technology and Concentration said the risks from green goo demand the most urgent foresight and caution.

	Responsible Nanotechnology: Worse Than Gray Goo
		If we ever get to the point where script kiddies can release dangerous gray goo, we're probably doomed—since it'll surely be harder to stop goo than to stop slow-moving, slow-thinking meat robots from pushing the wrong buttons.
		The position of CRN is that gray goo eventually may become a concern requiring special policy.
		Part of the horror of the "grey goo" scenario is the "greyness" of it.

	The Gray Goo Problem
		The subsequent colonization of the land-based carbon-rich ecology by a large and hungry seabed-grown replicator population is the "gray plankton" scenario.
		In theory, replicating nanorobots could be made almost entirely of nondiamondoid materials including noncarbon chemical elements found in great abundance in rock such as silicon, aluminum, iron, titanium and oxygen.
		The subsequent ecophagic destruction of land-based biology by a maliciously programmed noncarbon epilithic replicator population that has grown into a significant nanomass is the "gray lichen" scenario.

	[No title]
		Eric Drexler, known as the father of nanotechnology, today (Wednesday, 9th June 2004) publishes a paper that admits that self-replicating machines are not vital for large-scale molecular manufacture, and that nanotechnology-based fabrication can be thoroughly non-biological and inherently safe.
		Talk of runaway self-replicating machines, or âgrey gooâ, which he first cautioned against in his book Engines of Creation in 1986, has spurred fears that have long hampered rational public debate about nanotechnology.
		Science fiction writers focused on this idea, and âgrey gooâ became closely associated with nanotechnology, spreading a serious misconception about molecular manufacturing systems and diverting attention from more pressing concerns.

	Summary of findings in the projector screen review
		It delivers a great picture that is notably better than the Goo Digital Grey Lite, but not at the expense of the premium screens.
		But it can't match its easy assembly and installation, and it will be difficult for most folks to build a frame that approaches the elegance of Da-lite's Cinema Contour beveled frame in their garage.
