Natural gas tends to be more reliable than grid electricity. However.....if the poop really hit the fan, it's anyone's guess if the gas would keep flowing.
Poop hitting the fan is one way to make your own methane. Didn't you see beyond thunderdome?
Exactly.... but how would you install an emergency breaking system on a (contactless!) Maglev system without seriously restricting the the directions in which this can move? (diagonally...)
Because of the shoddy writing in the article and the summary, I can understand why you would think it's contactless. But it isn't. The similarity with maglev trains and the hyperloop is the fact that it uses a linear motor to move along the track. The elevator car is still affixed to a track/rail and does not levitate. When it needs to go sideways, it does so at specially located switchpoints where it traverses a horizontal track. This would be obvious from reading the articles or, for the short-attention-spanned, watching the embedded videos.
Both would be difficult to put in place on a Maglev system.
The maglev part is kind of a misnomer. It's not using magnetic levitation, per se, but rather using linear motors to move around. Yes, maglev trains use that technology to travel, but so do a number of launched roller coasters out there. Any it's being used as a replacement for the steam catapult in the latest U.S. aircraft carrier.
The elevator car is still in contact with a track, for mechanical and electrical reasons. It almost certainly has track brakes that require energy to release. That is, in the event of power loss, they are spring-loaded to engage automatically.
Additionally, since we are talking about a motor, you can do dynamic braking: short the stator windings together, and the back-emf created by the passing magnets will create a substantial drag force. Want to try at home? Drop a neodymium magnet down a copper pipe and see how long it takes. Or take an ordinary DC motor, short the leads together, then try to backdrive it.
Thoughts and prayers out to the victims and their families. Speedy recovery for the injured.
I appreciate your sentiment, but it would carry more weight if there were a subject and verb in there. For instance: I send my thoughts and prayers out to the victims and their families, and hope for a speedy recovery for the injured.

America has voted to be isolationist, anti-globalist, anti-science, pro-white supremacist, Islamophobic, batshit crazy Evangelical Christian, anti-immigration, anti-refugee and anti-business.
Blaming Trump is vacuous. We the People have spoken and it is what it is.
And this is the problem with the natural monopoly that has developed, and the reason why Net Neutrality is needed. Most people in the United States don't have a choice of ISP. They couldn't vote with their wallets if they wanted to, except to opt out of the internet entirely.
The summary talks about the PS3's "eye-watering" price, and its gaming legacy. However, it's more important contribution in tech history was the introduction of Blu-ray. Sure, Blu-ray didn't originate with the PS3, but other than a handful of $1000, stand-alone players, the PS3 was the route that Blu-ray took into the living room. For several years, the PS3 was the top-rated Blu-Ray player (in terms of features, speed, ease-of-use, etc.), and cost the same or less than stand-alone players. Some remember that a competing format, HD-DVD, was introduced around the same time. The success of the PS3 was the biggest single contributor (though not the only one) to Blu-ray winning that format war.
Another PS3 footnote in history was its use of the Cell processor: a Power core with several highly parallelized co-processors and coherent shared memory, which gave it exceptional physics and rendering capabilities (for the time). Sure, it never really caught on as an architecture, but it was something new and interesting at a time when processor technology was just a pissing match between Intel and AMD each doing x64.
What dolt at DARPA - an organization filled with pretty savvy people - came up with the acronym "XS-1"? Just say it out loud: "excess one". It just screams of government waste, no matter the merits.
I guess it could have been worse - the program's expanded name is "experimental spaceplane." If they had made spaceplane two words instead of one, the program could have been called "XSP", or "excess pee".
9 times out of 10 these studies have to get some sort of approval to test the devices. Garmin likely chose not to participate.
Have to?! According to whom? I could walk into any number of retain outlets and get purchase one today. How is the company then going to prevent me from using it as part of a study?
Power meters for bicycles aren't cheap either - maybe 1000$ or so.
For some models, yes, but by and large your information is dated. There are plenty of "consumer" models that are less than $500, and provide data that is quite good.
For more information than you can shake a bicycle crank at, I suggest taking a look at DC Rainmaker. He owns every device he reviews* and does lots of hands-on testing. For reviews of power meters, he typically tricks out his bike with 2-4 power meters (in different locations: crank arm, spider, rear hub, etc.), each with their own head unit.
* As he explains on his website, he often is doing his hands-on reviewing with pre-production models from the company, but always returns is and purchases his own - to confirm that is wasn't a special snowflake - before posting.
Those costs must be made whole by the firms operating the mines as they caused the air and water pollution killing their own workers.
While I agree that the coal companies have much to answer for - specifically, exploiting the land and their workers - I myself cannot renege on my own responsibility in this matter. I am a consumer of electricity, and products containing steel, and the myriad other things that coal contributes to. Therefore, I (and all of society, including those who think their solar panels absolve them) share the in the responsibility.
That said, I would love for coal to have to bear the burden of its externalities - they've gotten a free ride for way too long. If that increases the cost of coal and coal-generated electricity, then fine: it'll reduce electricity consumption, further reduce coal's share of electricity generation, and hasten a less carbon-intensive economy.
degree of concern for a +/- 2mm annual growth spurt... even if the millimeter is a measurement the voter understands
Millimeter!? I hear they use that new-fangled metric system in commie Europe. And them Japs use it, too! And the ruskies! And those weirdos what talk funny in Australia! And the entire black continent of Africa! And China, grrrrrrn, don't even get me started on China!
On the plus side, at least significant portions of Manhattan are build on solid bedrock. Venice, not so much: most of those buildings have a foundation of timber piles...driven into clay...in a lagoon.
Personally, I'm just waiting for the first incursions on Mar-A-Lago. I expect Trump to change his position on climate really fast once that happens. And I'm sure that more than one of the Trump Towers around the world is fairly close to sea level
Nah, he'll probably just find someone else to blame.
Or, given his age, undoubtedly high blood pressure, and obesity, he may well be dead before his monuments to opulent gaudiness are flooded.
Electric power in Germany is more than twice as expensive as it is in America
German also use about half as much electricity as Americans (per capita) [alternate ref], so I'd say it roughly balances out. And Germany's GDP per unit of energy is also higher than the U.S., so higher energy prices don't seem to be killing their economy. If anything, Germany gets a lot of flack from its neighbors and trading partners that it's economy is too strong.
Just because something is more expensive on a per unit basis doesn't necessarily mean that you'll end up paying more. If demand is elastic, you'll reduce usage as a result. Here in the developed world, and particularly the U.S., where our use of electricity is fantastically wasteful an inefficient, demand is VERY elastic.
Grandparent wasn't talking about the operating cost of Air Force One. GP was talking explicitly about how my total lifetime tax contribution squares against the fuel cost.
My broader point is, I think, still valid: Trump is on track to outspend Obama on using Air Force One for vacationing. We can reconvene this argument in a couple of years to see.
The sum of all the taxes you will pay over your entire life won't be enough to pay for the fuel spent by Air Force One when Obama went on a single vacation trip in 2015. What did you get for that?
I understand the point you are making, but I think you're off in your facts. Air Force One, being a 747, holds about 55,000 gallons of fuel. I'm fairly certain it can do Washington, D.C. to Honolulu in a single hop. Aviation fuel runs about $1.50/gal these days. So, about $80,000 one way. Back in 2015, fuel prices were higher. Air Force One's fuel is more expensive, because it receives more scrutiny and special handling. Even so, the cost of fuel for that trip was probably under $250,000. My household has paid that much in taxes, and I'm not even all that old. What is more, my household's share of the U.S. population is best counted in parts-per-billion, so my share of that cost was decidedly small.
What did I get from that? A modestly less stressed commander in chief. This is true whether it's Obama, Trump, or anyone else.
Round trip, DC to HI is about 10,000 miles. DC to Palm Beach (Mar e Lago) is about 2,000. However, whereas the Obamas typically took one annual trip to Hawaii, Trump has been to Florida about every other week of his presidency - and he's only three months in! Obama racked up about 170 vacation days over 8 years - about half that of G.W.Bush, and on a par with Bill Clinton.

Personally I was wondering if the CDC was including justifiable vehicular homicides. Tough to do apples-to-apples comparison without that information.

A Mercury capsule was about 3000 lbs. (google search) So, yes, it could.
And in Australia they call those people that fly into space "arse-tronauts".

On the plus side, at least significant portions of Manhattan are build on solid bedrock. Venice, not so much: most of those buildings have a foundation of timber piles...driven into clay...in a lagoon.
On that subject, writer Kim Stanley Robinson has a new book about a Venice-like NYC. Here is an overview and interview with the author.

I hear there will be display optimizations for using the OS while doing a handstand. (ref)
And LightDM will come pre-configured with a red color scheme, in which case people will refer to the OS as "Red Sonya". (obscure ref?)

Like the metric system?
Does that include Germany? Because everyone knows that Germany is a lot sunnier than the U.S. I suppose the U.K. must be in the same situation.
