It includes all sorts of things, from seats to air conditioning. Flying at lower altitudes keeps you from needing pressurization, but there's still all of those pesky "doors" and "instruments" and the like. With 30 hour flight times, you also need things like extra crew members and toilets and such.
Leaving humans out of the equation will save tens of tons on this sort of aircraft...
They save a ton of fuel by flying higher at higher speeds - compared to how fast they're flying. They can actually save some money by flying slower, but people don't like taking too long to fly cross-country.
Jet engines also get higher thermal efficiency by flying higher, in colder air, but you can get better efficiency by using things like turboprops or propfans at lower altitudes and lower speeds. Up to about 500 mph, turboprops beat high-bypass jet engines by a wide margin in efficiency, and at lower speeds (200 mph), are almost 50% more efficient.
One of the problems with propfans is higher cabin noise, but an unmanned plane skips that issue.
The Natilus website shows regular old jet engines, but I bet that changes...
There have been multiple proposals to do just that, but between the environmental lobbyists and the people who would rather use the money for a train they're going to ride about once, it's just not happening.
You mean when someone has a problem with something like a heart attack or a major injury, being an extra hour away from an emergency room could make a difference in survival rates?
You see, a "free market" is actually free, not controlled by government-run bureaucracies that make it very difficult for medical device manufacturers to produce something that ISN'T covered by patents any more.
...and with a few moments of searching the web, they could have a nice handy thumb drive full of images they would "detect" on some guy's computer, and get a nice little bonus from the FBI...
"Yeeeah, I found another one this week. Yup, it's surprising how many of these weirdos have computer problems and show up at my store. How soon does my check get here?"
ABC News and Rathergate. Fake news, through and through. Dan Rather still claims the story is true, even though everyone knows it's a fraud.
Dateline NBC and the exploding truck. They couldn't get the supposedly dangerous truck to catch fire, so they rigged it with an igniter for the camera. Yeah.
NBC News and George Zimmerman. They took his 911 call and edited it to make him sound like a bigot, when it showed nothing of the sort. Read up on it, and wonder how much of what you "know" about that case is actually true.
When the Ferguson shooting happened, a common slogan was created because Michael Brown supposedly said "hands up, don't shoot." The trouble is that only one person claimed to have heard him say that - his accomplice. The many actual witnesses heard nothing of the sort. Yet the mainstream news organizations ran with it, and the (much later) retractions have been, to say the least, understated.
There are dozens and dozens of such stories, with the big difference being that they're held up as "journalism" by millions, while the fake news you get from Facebook is usually only seen by thousands at most, and almost always has someone pointing out that it's faked in real time.
Most of the people whining about this seem to have no idea that the "fake news" they know about is only a fraction of the problem.
What's really funny is that about 90% of the things they like would fall under this umbrella, including a lot of content from the "real" media.
The "Russians Hacked the Election" story, for example...
The actual story is "the Russians hacked a couple of people at the Democratic Party (maybe) and embarrassed the hell out of them" - but the way it's being told, most of the Democrats you meet think there was actual nationwide vote tampering by Russian hacking. So far, the only vote tampering found was in Detroit, and it was done by hand, not by computer. Not to mention who won overwhelmingly in those precincts...
Two decades after the Democrats got caught taking money from the Chinese, and 32 years after Ted Kennedy BEGGED the Soviets to intervene in the 1984 election, NOW you're worried about a foreign country "trying to influence US Elections?"
Heh.
Obama's response today is funny, too. Just close a couple of known spy stations and kick a few people out of the country (when the hacking was supposed to have come from Europe), who will be replaced within the week. Yeah, that'll work.
They found no evidence of actual election systems hacking, the only thing they can even vaguely blame on the Russians is leaking the damaging things that the Democrats actually said in their emails, and most of the good stuff probably came from plain old insider leaks to WikiLeaks.
I wonder what sort of actions they're going to take against Democrat campaign staffers for having such terrible email security practices?
So when you see that 9.5 gigawatts of solar compared to 8 gigawatts of natural gas, it's more like 3 gigawatts of average solar output versus 7 gigawatts of gas...
If those scientists were doing real science, they'd be proud to have their names associated with their actions. Instead, they're ashamed and trying desperately to hide. That should tell you something.
Instead, they're going with "You don't need to know what we've been doing for the last several years, because, um, censorship? Something? Only Nazis would want scientific accountability!"
I've been to a UN Climate Conference. No science, just politics and a vacation on government money. When the weather turned unseasonably cool in Cancun one year, all of the important people left early because they couldn't sit on the beach and party.
So, at least $1000 per vehicle, and probably a lot more?
And then they'll be able to put up a bunch of sensors along the streets to keep track of where anyone goes at any particular time, and do things like monitor adherence to traffic laws.
Of course, they'll say "we would never do that," but we all know how that sort of thing works out in the long run.
We've had warnings about "radiation reaching the west coast of the US" a few times already. We've seen similar stories in 2015 and 2014 (a couple of times in each year).
In those, it was Cesium-137. Now, this group is all about Cesium-134, apparently because people didn't get upset enough about the Cesium-137.
"Possible false positives" may be their excuse, but no, it's not the first time someone made the claim of radiation reaching the west coast.
By the way: they weren't kidding about the amount being very small. It's 0.3 decays per cubic meter per second - which is a really, REALLY small number. The most amazing thing about the story is that we can manage to detect something that's so close to zero in real world terms. Three-tenths of a disintegration per second times (approximately) 30,000,000,000,000,000,000,000,000,000 molecules of water in a cubic meter of seawater...
(Someone check my math on this: it's late, and I'm sleepy...)
The thing they always gloss over in these "the Internetz is SLOW!" articles is where the slow internet is.
"there are still many parts of the country where slow DSL or satellite is sadly the best option"
Yeah, like way out in the boonies, where a lot of people move to get away from the "fast lane." That's where a bunch of the slow satellite connections are.
Nope. Plain old wars and good old fashioned political corruption did that.
The "drought caused the Syrian civil war" theory is, frankly, crap. It was based off of one paper, which built a big statistical mountain off of a molehill. They exaggerated the number of people affected by the drought, and failed to show any sort of cause and effect. For that matter, the ACTUAL cause of the migration was a financial - subsidies for diesel and fertilizers were cut.
The civil war in Syria, by the way, started two years AFTER the drought ended. If it was caused by the drought, it seems like the events would have been closer together.

...isn't just about not falling out of the air.

I do live in Florida.
And I do support the common sense restrictions on things like speedboats in areas where manatees live, and laws keeping people from annoying them.
You can stop talking now.
Well, a devastating blow to people who have invested their entire lives in telling people that manatees are dying off.
Look, it's fine. We know about them, we figured out how not to kill them by accident.
You did a good thing.
Now, it's time to scale back the fearmongering just a bit.
They're laying off researchers and engineers, not manufacturing workers. A lot of their engineering staff is overseas now.
Robots and automation? Not a factor.
Only when they are in a public place, performing their duties.
This is all about the expectation of privacy. Planned Parenthood might be, to a small degree, publicly funded,
"To a small degree" meaning "about 40 percent of their budget comes from the US government."
...when you get a USB stick that's not in a sealed container from the store, plug it into an old USB hub for a while to see if it blows anything up.
There have been multiple proposals to do just that, but between the environmental lobbyists and the people who would rather use the money for a train they're going to ride about once, it's just not happening.
You mean when someone has a problem with something like a heart attack or a major injury, being an extra hour away from an emergency room could make a difference in survival rates?
Do tell, Sherlock.
You see, a "free market" is actually free, not controlled by government-run bureaucracies that make it very difficult for medical device manufacturers to produce something that ISN'T covered by patents any more.
You know, like epinephrine injectors.

Sheesh, if he'd bought a $500 HD camera and a couple of lights, he could have made actual porn and turned a profit while still having fun.
This is hilarious.

It's almost like some major event happened five years ago that radically modified the health care system, making it less efficient and more expensive.
Let's see, what happened five years ago... oh, yeah. That.
People really seemed to like it before Jon Stewart went off the air...
The thing they always gloss over in these "the Internetz is SLOW!" articles is where the slow internet is.
