The warning at the top of that page makes it sound like these machines are useless in reality... or am I reading it wrong?

Oh boy. I'm going to build my own rotor for sorting calcium ions, even though I don't know what it's for.

>my face when people think that machines like this are viable

You can tell from these pictures that nobody who designs these things is a chemist, or has any bloody clue at all about how atoms actually behave.

[Anonymous No.2412208]

That thing would be fucking ridiculous to synthesize.

If you want to model nano-machines like that, yes, its called PC spartan or WebMO, good luck finding a contraption that allows you to specify a type of molecule, and have the same machine synthesize that in a set amount of time.

You should trust a 4chan anon who did a bionanotechnology-based MSci and is currently studying on a nanoscience MPhil course.

I normally don't like to talk about myself but in this case I feel it's relevant.

Nah man, I'm the real deal. See, I even spent like 5 minutes taking a terrible-quality picture of my textbook for you.

Atoms tend to prefer to be in bulk structures, where all their bonds are satisfied. Trying to assemble a little ring of carbon decorated with phosphorus on the surface just ain't gonna happen: rather than turning against each other, cogs will stick to their neighbours with bonding interactions. If not a formal chemical bond, generic dipole or Van der Waals forces will jam up any machinery that small.

Not to mention the constant onslaught of ambient atmospheric molecules, or thermal vibration tearing the structure to pieces. Something like this might work at cryogenic temperatures under ultrahigh vaccuum, but it's never going to be robust enough to be workable.

The best examples of nanomachines are found in nature: proteins. And they work a hell of a lot differently to mechanical devices with axles and gears. They work by being squishy, and behaving statistically.

Fuck the gears then. Who cares about nanorobots? As long as the mechanosynthesis tooltips can work then I'm happy. And considering they were researched by Freitas and Drexler and Merkle I'd say they have a bit more credibility.

Tool-based mechanosynthesis is cute, but useless for making devices in a meaningful way. Sure, you can push around and bond a single molecule of carbon monoxide over painstaking hours with an STM, but for nanomachines to be useful you need billions of them, all identical.

That's why top-down isn't all that useful, unless you can use very fast lithography techniques. But even then you can only really get 2D structures, hence, sure we can have nice nanoscale effects for flash memory or transistors or whatever, but lithography's never going to make you a machine with moving parts.

In what part of The Diamond Age is it mentioned?

[Anonymous No.2412489]

>>2412481
The general idea that nanophysics isn't like cogs and axles? It's in there, IIRC. Maybe I'm off base. That said, the supercomputers there ARE based on "rod logic".
