Unless this paper costs less than 80 times the cost of a sheet of regular paper, it's a dumb idea. Not to mention the energy used in heating every sheet of paper you use to 120C instead of just recycling it.
Replying to myself with one caveat: there are lots of tiny diamonds in asteroids, formed mostly by pressure in collisions involving carbonaceous objects. Different animals, but still "diamonds" in the crystallographic sense.
Most natural diamonds are formed at high temperature and pressure at depths of 140 to 190 kilometers (87 to 118 mi) in the Earth's mantle. Carbon-containing minerals provide the carbon source, and the growth occurs over periods from 1 billion to 3.3 billion years (25% to 75% of the age of the Earth).
Ain't gonna happen on an asteroid. A basic rule of thumb is that asteroids will only contain igneous materials, never sedimentary or metamorphic.
I suppose you think all roads should be toll roads and your bank account is auto-charged for each one you drive on?
Sounds like an awesome idea. It's not a new one, either. Private autos impose enormous external costs on society, amounting to a hefty subsidy for car ownership. There's no reason cars shouldn't pay their way in full.
That's just dumb, that's just dumb because you can't make a car smart enough to navigate daily traffic with all onboard sensors.
This is exactly how Tesla does it, and while it isn't perfect, it's mostly usable and still improving. It's silly to say something is impossible when we are already most of the way there.
This was not an automated flight, and was not unmanned: there were 136 passengers on board. Three people were killed, and 34 required hospitalization. The cause was pilot error, and the flight crew was convicted of involuntary manslaughter for pulling a stupid stunt with a loaded plane.
Use more rhetoric. Use more insults, make the conclusions more dire, and make the deadlines for action seem nearer and less attainable.
Funny how the same people who constantly whinge about "Political Correctness" and how much we need more straight talk, turn into delicate flowers when that straight talk is pointed at them.
People who still in denial about climate science are delusional nuts. Full stop. There is an actual reality out there, and those who refuse to accept that should be marginalized and ridiculed, and should be given exactly zero voice in policy.
Good for China, and good for us: the sea level rises for everybody equally, no matter which country is at fault. Today, the U.S. and China emit vastly more greenhouse gases than the EU, India, and Russia combined. Those two countries have a responsibility to the rest of the world to get their houses in order.
China is doing something about it, albeit first steps. The U.S., by contrast, is being run buy delusional nuts who think global warming is some kind of scam. Makes me ashamed to be an American.
No dark matter is not just normal matter that isn't emitting light. It isn't absorbing light either. If 90% of the galaxy was just non-emitting normal mater you'd see it blocking the luminous modules as dust clouds and globules.
Um.
Things that absorb light also emit it, necessarily. Look up black body radiation sometime.
+1. It's the best of the best, published in 2016.. third in a trilogy, so you need to read the other two first. They are also fantastic, but the third turned out to be my favorite. Should be strong candidates for the annual science fiction awards.
The Dark Forest. I love the Cixin Liu books... refreshing sci-fi.
Second this. The translation can be a little clunky, but it's old-school hard sci-fi with a Chinese viewpoint. (For example, the importance of political officers in the military is taken as a given, but all of the characters think it's sort of weird that the Americans have chaplains instead.)
I have thought about installing Signal, but then I always remember the laundry list of permissions it wants access to in order to install.
Here is a rundown on device permissions for Signal. Most of them seem basically necessary for a functional messaging app.
What is everybody else's opinion on Signal?
I've been using it for a few weeks, and I like it just fine. It is a transparent replacement for my default messaging app, and handles encryption to/from other signal users transparently. An additional perk is a Chrome plugin which lets me send/receive SMS messages from my browser. For a lot of obvious reasons, it is likely to be nowhere near as secure as a set of properly managed PGP keys, but IMO a lot of useful progress in widely deployed crypto has been hamstrung by paranoia, and letting the perfect be the enemy of the good.
One disconcerting thing is that it goes through your contact list upon install, and notifys you of all people on your contacts list who have Signal enabled, without the permission of those contacts. This should be configurable, and opt-in. Sad!
This wouldn't be a key you memorize, it would be a public-private key where the other part of the key is on another computer which may not even be in the same country as the journalist. There is nothing the journalist can do to get the key other than ask the colleagues back home to send the unit to Bumfuckistan which is a huge huge red flag.
Good luck convincing the police in Bumfuckistan this.

What they did is called a chosen plaintext attack, and is still damning.

Musk has gone full supervillain.

FWIW, there are diamonds in asteroids too.
Where did you ever get that idea? Diamonds are only formed under conditions you will find on a planetary body:
Most natural diamonds are formed at high temperature and pressure at depths of 140 to 190 kilometers (87 to 118 mi) in the Earth's mantle. Carbon-containing minerals provide the carbon source, and the growth occurs over periods from 1 billion to 3.3 billion years (25% to 75% of the age of the Earth).

I think it's in the British Museum.
It's in the Egyptian Museum in Cairo.
I wonder how you're supposed to smelt it in space. Perhaps space air is flammable?

You smelt it with the uranium you mine.
Mod parent up.

The Terrafugia Transition has a 23 gallon tank and under normal circumstances can go over 450 Miles.
The Terrafugia is a fixed-wing aircraft. Get back to us when you can do that with lift coming from ducted fans.
That's just dumb, that's just dumb because you can't make a car smart enough to navigate daily traffic with all onboard sensors.

Parent was being ironic.
here's what happened when Airbus built a fully automated airliner (with no human inside) and have it land itself:

True. But still something must be done.
You just contradicted yourself.
They should patent it.
You're right they should be put in re-education camps until they see the error of their ways. Preach on tovarisch!
No, they should just be ignored.

That's nice, but I'd rather you jackasses just fix yer fuckin' memory leaks.
Pro Tip: Stop "improving" shit until it turns into a steaming pile of donkey shit.
Dude, maintenance is boring.
Reality is funny that way. It doesn't care if you are convinced or not.
The reporter being rubber hosed most certainly will care.
