Exploring the Potential and Dangers of Molecular Nanotechnology

In summary: While some of the potential benefits are truly mind-blowing, there are also a number of potential dangers that need to be taken into account before anything can be done.

Hello. I am currently living in Detroit and hooked on a syndicated radio program called CoasttoCoast. They deal with all manner of interesting topics - from the cosmos through to who killed JFK. It is a 5 hour long show broadcast night. The other day they had a guest who spoke at length about molecular nanotechnology. Some of what they explained seemed too good to be true whilst other insights were frightening.
For example, nanomanufacturing promised cheap products at a fraction of today's cost whilst the military and terrorist possibilities were too awful to comprehebnd. (Apparently, the Russians were working on this technology in an effort to defeat America's nuclear sub fleet, removing MAD and tipping the balance towards the Soviets).
Can people please tell me more about this fascinating subject?
Thank you.

Nanotechnology, if ever developed to any degree, will change our world beyond recognition. Think of the information revolution: something intangible, self-replicating, and indestructible is suddenly one of the most valuable things on the planet. The source code for Windows XP...the instructions for the synthesis of a particularly effective anelgesic...the text of the next Harry Potter novel: any of these could fit on a memory stick or be transmitted around the world by a cable modem, but they are far more valuable than gold or platinum. (How much gold or platinum? you ask. Be quiet. I'm sermonizing.)

Nanotech is a lot like information. It is self-replicating, or could be--and the most powerful stuff will be. Imagine an aspirin tablet fired at the moon that converts it (the entire moon) into a solar-powered colony ship, ready to head off to Alpha Centauri, in a matter of weeks. That's power, and I can really see how it's possible.

The problem is heat. Sorry, a problem is heat. There are many more problems, and they may be insurmountable. (Just like the main problem with Star Trek transporters is that they're a product of wishful thinking and the necessities of producing a low-budget television show.) Heat: if you have a billion little robots waving their cilia about, every Joule of energy they expend is eventually converted into heat. Just doing order of magnitude calculations, it's hard to see how the poor creatures won't bake themselves to death, even if they move reeaalllllyyy... slllooowwwlllyyy...

So where is nanotech now? It's serious enough to appear in the 'hard' (scientifically rigourous) science fiction, but not serious enough be on anyone's twenty year forecasts. Nanoconstruction, yes, but full-blown nanotech, no way.

And what's the fun in building something out of individual atoms if you can't program it to make copies of itself from desert sand and cover the entire surface of the Sahara with solar cells?

Nanotech is no doubt capable of revolutionizng EVERYTHING in our world. However this technology poses a massive risk of a kind unimaginable. While the constructive powers of this technology are phenomenal as with any technology the destructive powers are FAR greater. technology like this would have to be controlled in a way unimaginable to todays "free societies." If anyone who did not like the US (or anyother country for that matter) got ahold of this stuff, all they have to do is program it to whatever task they want and release, nearly without fear of repercussion, as unlike a nuclear attack, nanotechnology can no only disable any mechanism meant to stop it, but it is much easier to prevent from damaging oneself (as might be the case with fallout in a nuclear war) because it will only do what you program it to do.

What decade is this? Or did I miss something!

i think he meant what nanotechnology promised, past tense

Thank You (plus correction)

Thank you for your answers to date. I would still like to know more.
Integral's question re: which decade I am in was unnecessary. The commentator on the radio was referring to some original research carried out by the Soviets prior to "normalisation" of relations between the USA and USSR. In fact (and quite a diferent subject I guess), I do wonder what co-ordinates are still programmed into the American and Russian missiles.
 

What is molecular nanotechnology?

Molecular nanotechnology is a field of science that involves the manipulation and control of matter at the molecular level. It involves designing and creating structures, devices, and materials on an incredibly small scale, typically in the range of 1 to 100 nanometers.

How does molecular nanotechnology work?

Molecular nanotechnology works by using specialized tools and techniques to manipulate individual atoms and molecules. These tools include scanning probe microscopes, atomic force microscopes, and electron microscopes. Scientists use these tools to precisely position and manipulate individual molecules, creating new materials and structures with unique properties and functions.

What are the potential applications of molecular nanotechnology?

Molecular nanotechnology has a wide range of potential applications in various fields, including medicine, energy, and electronics. Some examples include targeted drug delivery for more effective treatments, more efficient and sustainable energy production and storage, and the development of smaller and more powerful electronic devices.

What are the potential risks of molecular nanotechnology?

One of the main concerns surrounding molecular nanotechnology is the potential for unintended consequences and environmental impacts. As nanomaterials become more prevalent, there is a need for thorough risk assessments and regulations to ensure their safe use. Additionally, there are ethical concerns surrounding the use of nanotechnology, particularly in relation to its potential for enhanced human abilities.

How is molecular nanotechnology being researched and developed?

Molecular nanotechnology is a rapidly advancing field, with scientists and researchers around the world working on new techniques and applications. There are also dedicated research centers and organizations focused specifically on nanotechnology, such as the National Nanotechnology Initiative in the United States. Additionally, collaborations between various scientific disciplines, such as chemistry, physics, and engineering, are helping to drive progress in this field.
