What are the possible downsides, negative affects of using nanotechnology? To the environment, people, etc. Ta

Answer 1

Negative effects are like in any scientific discovery potential for destruction, weaponizing .
For environment only if you loose it free ( some scifi selfreplicators).
But in reality first problems were that since it is on nanoscale it had a harmfull efect on unprotected workers who are realy not prepared for nano dust so it got to the lungs and did some harm,
There was some recent scientific article, read it on slashdot who took it from somewhere,
Nanothech by itself is not perpetuum mobile, and like any kind of tech it has to be started and pointed , and there only goes human wrongdoings and mistakes.
If you treat hazardous application of nanotech like bioweapon, you will have the same kind of protection.
you will be in fear or you will not think about it.

Answer 2

the environmental effects of nano are still largely unknown. some of the worst human effects we have been living with for decades. diesel engine soot is a nanoparticle and we breathe it everyday, to different concentrations depending on where you live. the smoke from buring insense is another nanoparticle that the lungs absorb very easily due to its fine size.

nanobots are plain fiction, but then were many other things at one time. just read that the equations for invisibility have been worked out and it appears that materials exist, or can be made, that can make an object invisible to radio waves. while it will be more difficult to extent that to visible light (optical invisibility) the theory is now there.

neat stuff........

Answer 3

Forget about the self replicating crap (remember the stuff about computers becoming self replicating?)

A very worrying problem is that nano structures are the same dimensions as cells, viruses, bacteria, etc. They may interact in unpredictable ways.

Most nano technology is a solution looking for a problem although there have been fanatastically good examples of that in the past (eg lasers)

Answer 4

many of the individuals at artwork are irreverent or atheist or agnostic. Even my husband admitted the different day that he "doesn't understand what to position self belief in" anymore. each and everything became lots clearer even as he became youthful. i am going to't say for myself i'm as non secular as I once became, and that i became very strongly non secular and religious, i locate at the moment, i'm much better caustic quite than sarcastic, a lot to the point that when I understand i have purely stated some thing horribly irreverent, I seize myself and understand that in yet all over again and yet another position, i doesn't have stated one of those ingredient.

Answer 5

Ever head of the "great grey goo" theory of our demise?

It goes something like:
A rouge self-replicating nanobot gets out of the lab and begins doing it's job of using the matter around it to build copies of itself. There is nothing to stop it until all available matter is used up, thus leaving what was once this planet a giant blob of grey goo comprised of billions of self-replicating nanobots.

Answer 6

Read 'Prey' by Michel Crichton and give yourself the willies. A combination of distributed networks, self repairing and self replicating nanobots and the usual clumsy errors made by all human systems (hospitals, labs etc) and you've got one creepy tale.

Answer 7

I thought that would be a better thing for the environment. Its so small it uses less stuff and it takes up less space.

Answer 9

Self-replicating machines that take over the planet!

Scary stuff.

Answer 10

Security problems. LIttle bots tht creep into our systems and send vital info...
