Well I didn't mean it like they were useless. Guess I need to think about how what I'm saying can be interpreted. I'm just a realist about these sort of things. Right now they're too expensive to produce to make them particularly useful, though I fully expect they'll be common and effective building materials in the future.

Hey, I'm just happy somebody got the joke!
You're right that atomic & molecular level assembly is a ways off (using a tunneling microscope to move atoms one at a time is slooooooow).

But things that want to form crystals or other stable, predictable shapes (carbon & silicon are lovely, aren't they) can be combined at a gross level, or using the half-dozen techniques we've used for chip fabbing, to do some pretty cool things.  I'm fascinated by the possibilities that microfluidics have for medical diagnostics and eventually organ-replacement implants.  Kidney-on-a-chip is coming.

Materials science is fascinating.  When i was a young and stupid engineering student I foolishly believed that since we had the periodic table nailed down that new materials were just not going to happen.  It turns out that new manufacturing techniques are constantly making new configurations of those materials to great effect. Manufacturing them cheaply is the next step but honestly that is what engineers are for.  Find a financial reason to start making these things and we'll find ways to make them efficiently.

molecular superglue derived from flesh-eating bacteria? yeah, i'll pass on that one

the artificial spider silk and the graphene aerogel are pretty damn cool though. but 'density lower than that of helium' is causing some confusion in the comments. i'd guess the 0.16kg/m^3 desnity is for the mass of graphene in a given volume, but does not include the air held within the pores which increase the overall density to be just greater than that of air, which is why the 'stuff practically floats' but not quite. (air is 1.2 kg/m^3, being mostly nitrogen)

I still remember reading somewhere that put it as more a dollar figure.  "We're $20B away from developing fusion, but it costs $1B a year just to keep the lights on*".  As in if we spend $2B a year we'd have fusion in 20 years.  $11B/year and we'd be done in 2**.  The trouble is that the world is spending just over $1B/year, so we're nowhere near.

*Lights on, experiments being run, graduate students being developed into professors, but on the whole it's just treading water level funding.  Cut below $1B/year and you'll actually regress as professors skilled in fusion science retire and aren't replaced, major science infrastructure/labs wear out, etc...
**No, we couldn't expand funding that quickly and remain efficient, but 5 years with a Manhattan/Moonshot level funding drive would be possible.

Are you asking in a philosophical sense, implying through the word "impossible" that creating these materials somehow required violating the fundamental laws of the universe?

Or are you asking in a more practical sense, as in what properties these materials exhibit that no other previously used materials have?

No no no, these aren't self replicating machines. I'm honestly not sure a 'grey goo' scenario is POSSIBLE, because I'm pretty damn certain nature would have beaten us to the punch on that.

By "self assembly", we mean-

Well, there are two methods of making nano-structures. Lithographically, which is top-down, and has limits based o, among other things, the wavelength of light/an electron beam/etc.

The other method is chemically, or 'bottom-up'. This is also sometimes called 'self assembly' because once you start the reaction, it goes and assembles itself. The problem with bottom up is that it has a shiat-ton of disorder, too. In the 'spheres to the ends of rods" example, a lot of bottom up methods give you spheres sticking to each other, rods forming daisy chains or massive clumps, spheres sticking to the sides of rods-
Our method, in theory, just gives a controlled way to make sure spheres only *CAN* attach at the ends. It's not a self-replicating robot, it's just another tool in the nanotech toolbox.

And again, a grey-goo scenario is really difficult and unlikely, in part beause (among many, many other things), nanoscale things tend to be inherently unstable-bastards like to fall out of solution all the goddamn time. This is because bulk matter is, quite simply, at a lower energy state than nanoparticles.  You have to separate the nanoparticles from each other using either a 'steric barrier' (i.e., you coat it in something that keeps it from clumping to the other nanoparticles), or by making the nanoparticles charged, so they repel each other. And even then, change the salt content of the solution to much, or.. fark, maybe the phase of the moon is wrong and you didn't sacrifice the chicken properly, and bam, the reaction farks up anyways.

The aluminum bubble wrap sounds real quick to market if you can make it cheap enough, the titanium mesh could probably be used immediately to supplement and encourage bone replacement with a short time to market.

I'm curious about the flammability of carbon aerogels. That's a lot of surface area and we know carbon burns.

Spider silk from bacterium is a good idea. Transgenic goats producing a gram per liter of milk was pretty disappointing.

Molecular glue? More like molecular selective glue. But considering where they're starting from they might have a replacement for stitches. Or rather, a stitch replacement for cyanoacrylate.

I agree with the sentiment and would like to see this happen but there are problems. There does not exist a reactor design that can achieve engineering breakeven much less amount to a powerplant. Even with roomtemp superconductors the best we got would be iffy. There's a long list of plasma physics topics that we need to understand better before we can hope to make a powerplant. But there's no incentive and limited ability to investigate them given the funding situation.

There's a long list of plasma physics topics that we need to understand better before we can hope to make a powerplant. But there's no incentive and limited ability to investigate them given the funding situation.

That's kind of my point, isn't it?  Given the funding we'd be able to investigate them, and 'sufficient funding' allows extensive cost savings when you realize that you can get things the super-collider functioning by building it quickly enough that the parts you installed when you started aren't reaching EOL when you're finishing the last sections.

It costs roughly $1B/year to remain static with our current understanding/capabilities with fusion.  More than that allows us to advance.  Even more money would allow us to advance even faster, while at some point less funding would have us regressing.

We achieved energy positive the first time we set off a hydrogen bomb, but that's not going to help us power any cities.

What he means is that we have yet to produce a self-sustaining reactor that when given a steady supply of hydrogen can produce enough electricty to continue to power itself unaided.  All that we have produced as of yet are limited reactions that require huge amounts of external energy pumped into massive lasers and electromagnetic containment coils used to hold the resulting plasmas.

Depends on the context in which they'll be used. Just last night I was looking at aerogel samples to experiment with as the insulation for a camping mat (what you put under your sleeping bag for insulation from the ground). Turns out that enough aerogel cloth-like material to use as a mat in single-sample quantities actually costs about as much as the more expensive mats made of conventional materials do already. I figure all I'd have to do is sew it into some lightweight protective material and it could be the latest thing for ultralight campers.

Now I know that most of those mats are stupid expensive (as is a lot of camping equipment), but if the aerogel is as great an insulator as they say, this could be a common application for it that wouldn't be that out of line with current prices.

So if I'm reading this correctly (ie skimming it) it appears that these are gas turbines and require fuel to operate.  It's a great idea but a few things come to mine;

1)God damn that had better be clean fuel if you want this to be a re-useable device.  We are talking like laboratory conditions pure, many many orders of magnitude purer than the filthy gasoline most people put in their car.

2)Such pure fuel will be expensive, more so if these are disposable devices and you need to buy a new turbine with every fuel pack.

3)It appears that exhaust gases are quite hot, the cold section of one turbine mentioned was 900K (so like 627 C)

Thanks for the reading material for after work though.
