Nanotechnology, grew goo and space environment;

flashgordon · 2006-02-11 20:18:54

People have decided to fear shall we say Feynman nanotech for various reasons whether trying to win responsibility brownie points, or they just fear science and technology period. But, an idea that is much discussed now is creating a world government to keep feynman style nanotechnology out of the hands of humanity. We fear exponential growth so much, that we ignore history no matter what and try to find some government topology that can keep feynman nanotech out of the hands of humanity. On that note, I'd like to say no government topology is going to work if you have a bad society infiltrating government positions; you need a social organization that makes good people, and the leadership will follow just fine.

But, getting back to why we fear feynman nanotech is grey goo. I'm thinking Eric Drexler was the first guy to bring attention to this concept. But anyways, I'd like to say that outside of planetary surfaces, and mostly rocky worlds, grey goo is not a threat because out in space, radiations of all kinds will kill almost any nanobot. Although, calculation is needed, I'm thinking space radiation environments even in the least threatening space environments like ours will be substantially reduced. I'm sure somebody could creativelly do something, but that would take an even more substantial effort than just mundane manufacturing nanobots.

Obviously, on a rocky surface with a sufficient atomsphere to reduce radiations, we could set up some moderate amount of 'world' government, but if seems to me that if all one wanted to do was give the worlds populations 'restricted' black magic boxes that give lifes essentials, than you don't need an elaborate world government the likes that crn is suggesting.

Out in space? A democratic government is all that is needed to keep the political passions at bay(democracies only real function - not to solve problems scientifically). Many democratic governments societies of ones chosing should be more than possible out in space.

Gray goo is not a realistic threat.

When the Hamas got into power by a democratic vote(which they never addressed as a potential problem of making a world government; then again, they never mention any problems of a world government!), crn stressed that exponential growth is a major problem just a week or two later; in other words, their major issue for suggesting their totalitarian state is exponential growth; these are people of great influence because they are the concievers of the technology.

NANO is nothing without MACRO

Big is small,
Small is big,
Together they make the world,
So to speak,
From the trucks the size of houses
To the cells that make our flesh
The code that makes this story
Seems as random as a mess

From the begin to the end
From the large to the small
Evolution we pretend
Brings order to it all

A moment of conception
A bang to perception
Thust apart the space
That gives us our place

From the goo wich we grew
By the thunder of the gods
From nano to the macro
The world is fracal

Order ontop of order
From Complexity comes dextaraty
From connections comes perception
From the small the large is built
Without the large the small would wilt

Nanostructured fibers can impersonate human muscles

The liver can regenerate itself after taking damage, but whether that ability fades as we age has long been unknown. A new study has found that age doesn’t slow down the liver’s regeneration, and whether you’re 20 or 80, your liver is on average just three years old.

Nanotechnology, also shortened to nanotech, is the use of matter on an atomic, molecular, and supramolecular scale for industrial purposes. Nanotechnology as defined by size is naturally broad, including fields of science as diverse as surface science, organic chemistry, molecular biology, semiconductor physics, energy storage, engineering, microfabrication, and molecular engineering. The associated research and applications are equally diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular self-assembly, from developing new materials with dimensions on the nanoscale to direct control of matter on the atomic scale. The term "nano-technology" was first used by Norio Taniguchi in 1974, though it was not widely known. Inspired by Feynman's concepts, K. Eric Drexler used the term "nanotechnology" in his 1986 book Engines of Creation: The Coming Era of Nanotechnology, which proposed the idea of a nanoscale "assembler" which would be able to build a copy of itself and of other items of arbitrary complexity with atomic control. Also in 1986, Drexler co-founded The Foresight Institute (with which he is no longer affiliated) to help increase public awareness and understanding of nanotechnology concepts and implications. Recent application of nanomaterials include a range of biomedical applications, such as tissue engineering, drug delivery, antibacterials and biosensors. Nanomedicine sales reached $16 billion in 2015, with a minimum of $3.8 billion in nanotechnology R&D being invested every year. Global funding for emerging nanotechnology increased by 45% per year in recent years, with product sales exceeding $1 trillion in 2013 https://www.nsf.gov/news/news_summ.jsp?cntn_id=130586 Nanotechnology has provided the possibility of delivering drugs to specific cells using the nanoparticles.

For Mars_B4_Moon re topic ... it is good to see this topic brought back to view in the present time.

Thanks in particular, for your reminder of Eric Drexler's book "Engines of Creation" and for your concise summary of the field and it's potential.

I am ** most ** interested in the potential of nanotechnology to solve the long standing problem of separation of molecules. I've been attempting to describe a possible implementation of nanotechnology to sort molecules in the "water preparation" topic. I liked the description of small machines "swimming" in a fluid to perform various functions.

A possible implementation of the molecule sorting system is in precisely ** that ** environment ... individual nanoscale machines would swim in water to be cleaned, and they would snag molecules of interest and transport them to collection points.

We do not currently have any members in the forum who are capable of doing work (research or commercial) in this specialty, but the forum is open to new members. Please see the Recruiting topic if you are interested in collaborating with others via this site.

NewMars now has a repository for data (via Dropbox) and it has a Professional Zoom account for collaboration.

I would like to thank Mars Society Executive Director James Burk for entrusting the forum with use of a Professional Zoom account.

Side Note: The title of this topic has the curious expression: "grew goo" .... I think that flashgordon might have been inspired by "gray goo", which is a real concern, and which has been the subject of worry for decades. If Mars_B4_Moon has time (and I know time is limited) a post on the history of the invention of the concept of "gray goo" and all the publications and presentations it has inspired would be a valuable addition to this topic.

Merging with machines is on the horizon and Nanotechnology will be key to achieving this. The ‘Holy Grail of Nanotechnology’ is the replicator: A microscopic robot that rearranges molecules into desired structures. At the moment, molecular assemblers exist in nature in us, as cells and ribosomes.
