TFA is just a long Whataboutism rant. The fact that Chinese firms acquiesce to demands from the Chinese government, in no way whatsoever excuses the misbehavior of the American government.
The Chinese judicial system is not comparable to the American system. They do not have an independent judiciary, so expecting a company to "challenge" an order doesn't make much sense. They also do not have an adversarial system, with a defense attorney and prosecutor trying to "win" regardless of the merits of the case, with an impartial judge as arbitrator. In China, the judge is often actively involved in the investigation, and will directly question witnesses. Their justice system works completely differently, in both good ways and bad.
Multiple small counter-rotating vortices will dissipate more easily than one big vortex.
The symmetrical shape will allow the landing "pads" to be bowl shaped, directing the draft upward and outward, while the enclosed ground effect reduces the needed lift. The aerodynamics works out very well.
They'll require wider clearances than a standard chopper.
Not at all. A Huey has a rotor diameter of 48 feet, and an overall length of 57 feet. This new aircraft is way smaller.
He doesn't care about science, or exploration, or doing things the right way.
There is no scientific reason to send people to Mars. It is a political stunt. Every president is for it, but they all extend the schedule so the big spending will occur after they leave office.
Guess what? We aren't going to Mars by 2030. Here's the reason: National Debt Clock.
If you can afford to pay $500 a week ($24,000 a year) just to speed up your commute- many people on here would consider you rich.
My regular commute is from my bedroom to my office downstairs. About 50 feet.
But I do have to travel to Palo Alto a few times a month, and to SF and SFO occasionally. $100 to save two hours would be worth it, especially since gas and parking for a conventional car is going to cost me anyway.
Yup. Ridden in them hundreds of times. Marine infantry.
The downdraft is considerable, but the many small rotors on these aircraft produce less than a single big rotor on a conventional helicopter. They are also much lighter, and need less lift.
But a conventional parking lot shared with cars is not going to work. They will need dedicated pads.
So a section on the top of every parking garage and most large buildings to provide last-mile transport to work.
Indeed. Helipads are already common on many buildings, and many more could be built. There will be no shortage of landing spots.
I don't think these will be only for "the rich". During rush hour, it can take me 90 minutes to go from San Jose to Palo Alto, and 2 hours to SFO. If I could take an air taxi for $100, I would.
These aircraft are electric and non-polluting, and getting even a few percent of traffic off the roads can reduce congestion and benefit everyone.
It's entirely plausible that he is suffering from some amount of dementia
Unlikely. Dementia is defined as a loss of cognitive functioning. But there is little evidence that Trump is getting worse. He has always been this way, even when he was in his 20s. You can't "lose" something you never had.
Should one rather say that humans are a source of Ebola infections in bats?
No. There is zero evidence that bats get ebola from humans. Ebola is not endemic in humans. There is currently a flare up in the DRC (a long way from Liberia) but usually there are zero people with ebola. Humans are not the natural host for ebola, and it does not transmit well from human to human. Most outbreaks die out quickly, in part because the virus kills its victims before it has a chance to spread.
Says research on the subject... do you have any other dumb questions?
Biometrics are widely deployed. How many in-the-wild exploits have there been?
Despite the research, in practice biometrics have proven to be more secure than PINs or passwords. About 5% of debit card holders write their PIN on the card. Biometrics work well even for stupid and careless people.
The smart time to renounce citizenship is as soon as you graduate from college. You have near zero net worth, and likely are in debt. But you have plenty of earning potential.
Returning to the US is not a big problem if you establish your new citizenship in a country with a visa agreement. Eduardo Saverin, co-founder of Facebook, chose Singapore, which has a visa waiver agreement with America. He can travel back-and-forth at will.
Because the point of children in China is to support their elderly parents in retirement. How can they do that if instead of saving, they are taking on debt? That is selfish and disloyal to their family.
Chinese culture takes family loyalty very seriously. On a Chinese law exam, one question asked if both your mother and GF were drowning, which would you save? If you chose your GF, that was the objective legally WRONG answer, and you lost points.
Personal debt is much less common in China than in America or the UK, and it is considered more shameful. People usually pay cash for cars, and many own their houses out-right, with no mortgage. It is even harder to get a mortgage for a 2nd home.
Most Chinese don't even have credit card debt. Their mobile payments system, which is nearly universally used, is based on direct debit, not credit.
Before you can marry a Chinese girl, her family will run a credit check. If you are in debt, you are going to be a genetic dead end, along with the other 30 million surplus single men.
It's not a power generation technique, it's a power storage and carbon sequestration technology.
Sodium is made this way: Na2CO2 + Energy = 2*Na + CO2
The process in TFA does this: 2*Na + CO2 = Na2CO2 + Hydrogen
The CO2 in the two process CANCELS OUT. ZERO carbon is being sequestered.
The net effect is to convert electricity into extremely expensive hydrogen... presumably so the H2 can then be converted back into electricity.
If your goal is to time shift the electricity by storing the H2, then you need to also account for the electricity needed to compress or liquify it, making it even more expensive and inefficient.
Renewable be used in the metallic sodium manufacturing?
If you are generating renewable energy, you can just put that into the grid to displace electricity from fossil fuel. Why use it to create sodium metal, and then just turn around and oxidize the metal back into what you started with? That makes no sense.
The process described in TFA is completely pointless. Sodium metal is made by the reduction of sodium carbonate, using electricity as the energy source. The battery in TFA converts the sodium metal back into sodium carbonate, with the excess energy released as hydrogen gas. The net effect is just to convert electricity into hydrogen via a very expensive and inefficient process.
Nuclear and renewables are used to generate electricity. Petroleum is used for transportation. They are two different markets.
The petroleum market may be crushed by better/cheaper batteries, but not by more efficient electricity generation. Electricity is already way cheaper than gasoline. The problem is how to take it with you on the road.

Do you ever go to the Palo Alto Creamery or YAYOI?
Yes, I have been to both. My wife used to work in Palo Alto, near Stanford, so I have eaten lunch in most restaurants along University Ave.

No western city is going to allow this.
They already allow helicopter shuttles. How is this different?
Having many smaller rotors won't matter
Multiple small counter-rotating vortices will dissipate more easily than one big vortex.

Nobody else, Republican or Democrat would ever suggest such a ridiculous and obviously ego catering idea.
Sure they would. They just wouldn't do it publicly.
With Trump, there is no filter. What he says in private is what he has in public. This is what his supporters love, and his detractors hate.

I thought the culprit was metal, aluminum specifically from pots, un-coated aluminum cans, etc.,
that found its way into the brain.
No. This was debunked long ago.
Myths about Alzheimers
That is what I came here to say. Floss your teeth.
No. Bad advice. Get a Waterpik. Waterpiks are more effective than string flossing at reducing plaque.
Waterpiks are also faster and easier to use, and people are more likely to use them consistently.
Add a jigger of fluoride mouthwash to the water, for even better results.

Secure voting is easy. Anonymous voting is also easy.
It is doing BOTH that is hard.
Security for congressional floor votes is easy because their votes are public knowledge.

Why is debt necessarily shameful?
Because the point of children in China is to support their elderly parents in retirement. How can they do that if instead of saving, they are taking on debt? That is selfish and disloyal to their family.

Say what? I've never, ever seen that in europe or Canada
You should travel more widely. Most cashless transaction occur in Asia.
China and SouthEast Asia use systems based on QR codes.
China alone has more mobile transactions than the rest of the world combined
- Because remote places with lots of sunlight (deserts, or close enough) typically don't have a convenient grid connection you can hook into?
So you are going to haul truckloads of sodium carbonate into the desert, use solar energy to convert it into metal + CO2, and then haul out the metal?
If the goal is to make the world's most expensive electricity, this is a good way to go.
Because there is often too much renewable generated to be consumed at the time.
As I said... STORAGE.
But why not use something efficient instead, so you don't waste most of the energy?
Even if you want to fixate on sodium, there are far better methods, such as sodium ion batteries that have a round-trip efficiency of over 80%.
Renewable be used in the metallic sodium manufacturing?
If you are generating renewable energy, you can just put that into the grid to displace electricity from fossil fuel. Why use it to create sodium metal, and then just turn around and oxidize the metal back into what you started with? That makes no sense.

The battery in TFA converts the sodium metal back into sodium carbonate, with the excess energy released as hydrogen gas. The net effect is just to convert electricity into hydrogen via a very expensive and inefficient process.
That sounds odd... where's the power coming from?
The energy comes from the oxidation of the metallic sodium.
So where does the metallic sodium come from? From burning fossil fuels to reduce sodium carbonate, of course.
They have discovered perpetual motion. Then they just bleed off the excess energy as hydrogen gas.
Global warming is solved! Whew, what should we work on next?
