It should've worked, too. Just leave things alone and the economy will come roaring back.

Trouble is the financial guys, now as ever, have no idea how to run an economy.
If you have an experiment that shows a violation of conservation of momentum, the correct response is to send a grad student down to find out where the mistake is.
Not hold a press conference and start packing your bags for Proxima.
If you've read Parkinson's Law (and you should!) you'd know that institutions begin their decline just at the time they move into their perfect, palatial quarters.

Reducing the sound transmission is good, of course, but usually difficult and expensive. Adding more absorption inside the space is always good, will gain you a few more dB, and improve the environment for listening.
But the best and cheapest method is to add noise.
How can adding noise improve the situation? There's already too much noise! This has to do with the nature of hearing and attention - the so-called invisibility of the familiar. Ever notice that when the AC or a fan turns off you suddenly notice it, while you didn't notice the sound before? That's because the mind will tune out and ignore meaningless background.
If you can add enough white/pink noise to mask the offending noise then your attention will not be distracted by it, and eventually all of the sound will fall beneath your attention. This is the usual treatment for tinnitus, ringing in the ears, and many sufferers can gain substantial relief by it.
A quick way to try it out is with your home stereo. On FM mode, tune between stations (and turn off muting). This will provide very nice white noise with adjustable volume. Give it a couple of hours at least. There are inexpensive white noise generators available.
A little classier is falling water, such as an inside fountain. This is more towards lower frequencies (pink noise), but the particular random nature of the sound is very calming for most people.
A couple of nuke blasts on the moon would let us keep the Earth's rotation in sync with our atomic clocks. It's practice for asteroids, and good entertainment too!
"Comrades," he said quietly, "do you know who is responsible for this? Do you know the enemy who has come in the night and overthrown our windmill? SNOWDEN!" he suddenly roared in a voice of thunder.

Your body is composed of some 40 trillion cells. Each one comes from a line of cells going back billions of generations, every one of which succeeded in reproducing and projecting itself into the future. DNA is not easily squelched.
The solution is to allow a given account only a finite number of edits to a given page, something like 100-300 or so. This would discourage squatting, ownership, and edit wars.
Funny thing how so many earthquakes are on a "previously undiscovered fault."
The only things we know about earthquakes are: (1) little ones seem to happen after bigger ones, and (2) they roughly occur in the same place as previous ones.
The specs on that unit give some idea of what's possible with a miniature peltier dehumidifier:
Weight: 3-1/2 pounds Rate: 8 oz per day at 80% RH Power: 22.5 W
That's a lot of weight, and it would take quite a bit of solar panel to get that much power. And all that for a thimble-full of water in an hour's ride.

Does hydrogen have a lower flashpoint or some other quality which makes it more dangerous?

Hydrogen is an unusual fuel. It has a high leak propensity and wide flammability limits, 4–75% by volume. Among all fuels, hydrogen has the lowest molecular weight, the lowest quenching distance (0.51 mm), the smallest ignition energy in air (28 mJ), the lowest auto-ignition temperature by a heated air jet (640C), the highest laminar burning velocity in air (2.91 m/s), and the highest heat of combustion (119.9 kJ/g). Hydrogen flames are the dimmest of any fuel. Hydrogen embrittles and attacks metals more than any other fuel.
Mind you, this is from researchers generally inclined towards the use of hydrogen.
Funny that the rise in shingles cases has occurred since varicella vaccination became common.
What's changed is that there is no longer a large amount of chicken pox virus floating around the community, constantly challenging folks' immune systems. To get exposed you now have to go to a doctor and buy it. (This is the "shingles vaccine".)
For many diseases, such as polio and measles, vaccination is undoubtedly a huge good, preventing a huge number of deaths and tragic illness. But for varicella, the vaccine may result in more harm than good.
The one gTLD that makes sense would be.rad, though I haven't seen this proposed. The idea is to link nationally or internationally assigned radio call signs, to a URL: call_sign.rad.
This is sensible as a gTLD, as there is a one-one correspondence between call signs and legitimate owners. There is a need and value to having a (somewhat) reliable or trustable way to locate the radio stations on the web.

Homer Dudley had a working vocoder pre-WW2, which was used in the encrypted voice system SIGSALY.
From Wiki, this encoded voice into 12 signals, each with 6 levels (call it 2.5 bits) at 25 Hz. That's about 750 bits/s.
