Don't know where this belongs. Like most things in the world, I don't know a thing about it, and I don't understand it so I won't be in on the discussion anytime soon. Wondered if anyone here thought this was something worth talking about.

I don't know much about this stuff, either.
Though I am concerned that the Friends of the Earth may end up getting things wrong, it does seem to me that nanotechnology does need careful, rational scientific oversight. From what I understand, health and environmental side effects, even the inhalation of fine particles, haven't been considered by some researchers, who naturally tend instead to focus on their intended applications.
Wikipedia's article on nanotechnology speaks to some perceived potential risks:quote:
Potential risks
For the near-term, critics of nanotechnology point to the potential toxicity of new classes of nanosubstances that could adversely affect the stability of cell membranes or disturb the immune system when inhaled, digested or absorbed through the skin. Objective risk assessment can profit from the bulk of experience with long-known microscopic materials like carbon soot or asbestos fibres. Nanoparticles in the environment could potentially accumulate in the food chain. [3]
An often cited worst-case scenario is "grey goo", a hypothetical substance into which the surface objects of the earth might be transformed by self-replicating nanobots running amok.(Due to recent suggestions, this case has been proven as "impossible".)
Societal risks from the use of nanotechnology have also been raised, such as hypothetical nanotech weapons (e.g. a nanomachine which consumed the rubber in tires would quickly disable many vehicles), and in the creation of undetectable surveillance capabilities.
Now, I hope someone more expert on this subject than you and I, Gorgo, will interject some comments.

Basically nanotech is all about creating new molocules which behave in a predicatable manner when a certain condition is met. Like all new molocules these nanoparticals react with the environment and are not all inert, therefor they need regulation so that they are treated as potential toxins until studied properly.

| It strikes me that it is really the self-replicating part that is scarey since that seems to be the point at which we can quickly lose control of its application. A blanket prohibition of self-replication seems a sensible minimal condition for work until we understand things a whole lot better. |
