You know, most people solve that by using a smaller glass. An insulating one is normaly a good enough second option (but it's nice to feel the glass temperature).
Discovering a more hydrophilic material that's a worse heat conductor than glass looks like a huge enterprize for too small a gain.
Another small detail to add to your comment. The faster you turn the vapor into liquid, the lowest is the pressure at the condenser, reducing the work of the pump that creates vacuum after the turbine* and increasing the overall efficiency of the system.
Also, if you have a bigger heat conductivity, you can apply a smaller temperature gradient into the vapour. That could theoreticaly improve the efficiency, but I don't know how that part works in practice.
* Yes, the vapor goes from the turbine into a pump. Seems counterintuitive, but you want to condense it, what is easier to do in a highter pressure, but the turbine works much better with vacuum... In the end big plants gain efficiency by putting some work back into the steam.
Capitalism requires that increased productivity should cause increased wages.
Nope. In a capitalist society, labor is always competing with itself. Increased productivity leads to less positions, thus increased competition and lower wages.
Things may fix themselves after the lower cost leads to increased consuption and more work positions. But that may take a time, and there is no reason to belive the two phenomena have the same amplitude (thus, at the long term, increased productivity can lead to smaller or bigger salaries, one can't tell beforehand).
To be fair, after reading the report, it looks like they pocked holes at the external enclosure, and threw water around the internal enclosure. That cooled the battery and helped extringuish the fire.
I'm still not convinced it was a good idea (the situation could turn bad easily), but it's not aas bad as it sounds.
You probably used a different kind of powder. If you used a normal powder extinguisher (for C fires, or for A, B and C) it's water soluble, while you probably didn't want to throw water all around the place, it's a very easy thing to do at open spaces.
But the extinguisher for metal fires has bigger grains that don't fly easily, don't spread much, and can be collected again with a broom.
In fact I'm quite surprized that a litium battery could:
1 - Be damaged enough to catch fire, yet not explode. 2 - Receive a jet of water based "fire extinguisher", yet not explode. 3 - Have several holes punched into it, yet not explode.
Now I trust Tesla cars' safety much more. By the other side, I'm quite surprized that firefighters threw water at a litium fire (but most powder extinguishers are almost as bad), and punched extra holes in it (to let the water out, maybe?), but not in a good way.
I use them, the same way that I use the proprietary drivers of my GPUs. If there were a virtualization software that run with the main kernel and satisfied my needs, I would use it.
Well, that's you. I, on the other hand, do care a lot if I can use my GPUs with unmodified kernels or not, and once one good enough choice has a free driver, I'll certainly stop buying ones that lack it.
Take a look at how rocket weight decreases with the energy density of the fuel*, and then read your post again.
* No link. Sorry, but I won't go out of my way to digg one for a random A/C. Try googling something like "rocket equation", and reading the relevant Wikipedia articles. You'll find it if you bother searching.
Shouldn't the neutron be paired with something composed by its anti-quarks? If so, you'd need a photon with about 2TeV, what needs an accelerator at the "huge" end, not "lab-sized".
Also, that's not my area so I may be completely wrong, but it looks quite unlikely that you'll generate exactly 6 quarks with different color and barionic numbers, so that they can organize as a neutron.
Also, be wary of your network cards, hard drivers, pen-drives, keyboards, mice, DVD drivers, and watever else you plug on your computers. If you plug your cellphone or tablet at your PC, you've already lost the PC.
And be wary of binary software distributed to you. Even if it's personally signed by someone you trust (and you trust the certificate you got), his computer may be compromissed. If it's not signed, well, you've already lost.
Changing your OS or trusting the manufacturer of your processor won't make any of that go away.
Err...there's nothing stopping people now from setting up their own servers at home
In most of the world yes there is. There are government granted telecom monopolies that will block ports at random, unless you pay a small fortune for a business account.
Do you know what scales nicely? A thousand different solutions where each won't scale.
If you convert your waste into fuel, you solve two problems: you get a bit of fuel, and you get ride of your waste. It does not need to scale beyond the waste supply for completely solving the second problem, and it will increase the efficiency of the inefficient solar energy collectors we use today.
Now, if you want to help at increasing the efficiency of the crop growing and harvest, go ahead. it'll add (or, more specifically - multiply) to this.
Remember when netbooks changed the game, bacause nobody was mass producing cheap portable PCs that were portable enough, or when big screen smartphones changed the game, because nobody was mass producing smartphones that had a big screen, or when tablets changed the game, because nobody was mass producing a tablet that could run tablet software, or when the Raspberry Pi changed the game, because nobody was mass producing a cheap good enough computer with usefull I/O?
Steam is now mass producing a PC that will fit well in the living room. There are lots of small companies in that ninche, with expensive offers, and no big player. That game is changing now.
Currently Steam does not put walls around your software, and neither spies on you. Apple does both, Ubuntu does the spying, but currently does not create walls.
Installing Debian was once a hell of lots and lots of setup, obscure questions, and things that warned you that would burn your computer if you entered the wrong value. You often had to build boot disks with the modules required by your computer, and recompiling the kernel was often the first thing you'd do on a newly installed system (the second being reconfiguring X).
Ubuntu came, and didn't require any of those steps. Even if you needed proprietary drivers, it was just a matter of putting the CDs at the trail, and answering a few questions.
Fast forward to now, installing Debian is just a matter of connecting to the net, and answering very few questions, after that everything just works. Installing Ubuntu is just a matter fo putting a DVD on the trail, and answering very few questions, after that you better pray that everything works, because whatever don't, you won't be able to fix anymore (unless you replace most of the system).

I don't think the US gov can do any extra communication monitoring.
Yeah, Windows has extremely powerfull configuration management tools because managing Windows configuration is actualy a problem.
By the way, Puppy solves a different problem, one that most Windows admins can't even see because they are too short-sighted.
I more than once had to use Open Office (or Libre Office more recently) for undo a mess created by Word 2007 trying to open Word 2007 documents...

Gasoline + hight temperature = boom
If the gas is inside the tank, only the tank explodes. If it is spread under the car, the entire car does boom.

I'm sure it will make it possible to post non-ascii characters too.
Last time I tried it, I couldn't make it work the way I wanted. But you just made me try it again, so thanks.

If I understood the anouncements correctly, with aptitude you can have postgres quite easily.

If you make sure it does not spy on the users, and has no system wide DRM, no problem at all.
