Could we produce a nanobot that could push two atoms together till they fuse??
IMHO, no. Fussion among the common susable elements, assuming your method is to create a power source, requires a high initial kenetic energy. For instance, to initiate a deuterium-deuterium fusion reaction, you need an initial kenetic energy of about .25 MeV, which is like two billion kelvins, a pretty hot temperature. I don't think your nano-bots could get the kinetic energy of molecules up to this level.
I imagine a simple nanobot with two arms which would collect the two atoms and simply push them together. Is it possible for the molecular arms to have the strength needed to do the job? or would the molecular bonds in the arms just break apart with the forces involved?
Basically fusion occurs when two atoms get close enough together that their strong force overcomes their electric repulsivity. As mentioned above, you need a large kenetic force to do so, their not going to naturally overcome their electric repulsion. The only real method to do this, is to excite them to a high enough temperature, for temperature is the average kenetic energy of a substance. I think you;d need more sudies to determine if im right or not, but i don't think your arms would hold up.
You could make a nice nanobomb. Get a large bucket full of these bots to do it at the same time and bang.
Would you like a glass of water Mr. President?
Your nanobot is also made of atoms, as are you.
Could you please elaborate what your trying to say? This really has no point, we know we're made of atoms, how does this statement contribute?
Yes, you can do some studying on nanotechnology
duh? i don't think the point of his post was to ask if he should study about nanotechnology, i think it was to assess the possibilty of nanorobotics in cold fusion.
scientists can already push together millions of molocules from say; air, water, and soil to create potatoes, and what nots.
Whats your source for this information? This sounds like on Star Trek, where they ask the "replicator" to make them a steak, i think your getting sci-fi mixed up with reality there buddy
