Yes, for "every substation" there is no point. Diminishing returns.
But that doesn't mean the batteries don't solve a problem that's a big issue outside the "first world".
I don't know what you call "sub stations", over here, substations are the "last mile" transformer, converting 13.2KV into 220V. Then there are the "stations", that turn 132KV into 13.2KV. There are only a couple of them for my city. They could certainly benefit from a bank of batteries, and it would be, probably, very cost-effective, since otherwise the solution is to add several hundred kilometers of new wire to the generation plant.
In fact, that kind of station over here, actually has banks of diesel generators to absorb the peak demand. This will be just converting this solution to batteries.
If you want to print photos in low volumes, you can have them printed for a few cents almost anywhere, or you can buy a dedicated photo printer, such as the Canon SELPHY which uses dye sublimation, which means no liquid ink to dry up. That last bit really depends on your needs. It's a very niche market.
I have a shop, and "on the side" we print A3+ size inkjet copies. Obviously we use a CISS (Continuous Ink Supply System, in other words, external ink tanks with hoses connected to the print head), Maintenance is such a bitch. We do print something at least once a week, but sometimes the head "de-primes" and you have to spend a lot of ink re-priming the head. The amount of ink I spend re-priming a print head is more or less "one cartridge" (or about 10ml)
No, it would not be vastly improved since it is already very resilient in most places. Drastic improvement can happen where resiliency is an issue, which is not in very many places at present
Grids are "very resilient" in US and Europe, and a few other places around the globe (Japan comes to mind).
Those people make up about 1B of the population. The rest of the world (6 Billion people) don't see "very resilient" or reliable power. I had a 10 hour blackout the other day here in North east Argentina. Granted, it was 45C at that moment. The grid gets very flaky when temperature is over 40C because of the sheer amount of air conditioners and the few days a year it gets that hot. But that's pretty much the situation in the rest of the third world. "Diminishing returns" means doubling the amount of money put in a grid will take it from 97% uptime to 97.1%. They prefer expanding the grid to people that have, you know, 0% availability.
Grid tie inverters feed off grid frequency. They need to see nominal frequency in the grid in order for them to start pushing current into it. If the frequency goes out of whack, they go into standby until they see nominal freq again.
Also if a line goes down, your tiny 10kva inverter will just shutdown on overload when trying to feed the whole neighborhood.
1. All your nodes are of the same brand, model, and revision. 2. If that particular implementation of the Atheros chip or whatever actually works fine with meshing 3. The driver support for that particular embedded linux you want to use is good 4. You are willing to accept speeds in the "single digits" of megabits even with "single digits" of users.
Meshing will obviously never work even closely as good as a 1300mbit AC device at 5Ghz in the same room. But that's what people tend to benchmark it against.
It seems like the biggest hurdle for Amazon in other countries is that most other countries' parcel delivery systems are a total gamble as to whether or not your package (pick two):
A) arrives within one month B) arrives without damage (physical drop/crush or water) C) arrives at all
Doubt it. That's true only for international shipping. Most countries have a relatively developed post system that can deliver parcels. Especially to urban areas, where internet access is available. Sure, packages to a deep forest village in Africa may not be delivered within one month, but then again, those people are most likely NOT to have internet access or even a credit card.
As they get bigger I can see them building their own air strip and warehouses in each country, maybe even a private seaport in largest cities like Rio and Buenos Aires and partner with the government to do some sort of privatized customs. That's some serious cash outlay, but it's almost impossible to get quality products in third world countries. I'm traveling currently and the mid-tier ($10) headphones (about 1 weeks local wages) aren't even comparable to the cheapest headphones you can buy at walmart. For $15 you get a pair of amazon branded headphones that's equivalent to $35 local economy quality.
That's because corruption is rampant. That is definitely not going to happen in Argentina. And most of Latin America as well. Especially in Argentina. Argentina's customs were founded in 1534. And Argentina, in 1816. And the only reason for Argentina's independence is... to gain control of customs.
"some sort of privatized customs" that's really how "Rampa 4" at the Ezeiza airport works. DHL, FEDEX, UPS and other couriers have a dedicated customs where your packages are cleared at any time apparently (I've received customs notifications from DHL really late at night).
I'd risk saying neither do. Amazon does not operate even remotely of what you could call "worldwide". They are only big in Europe and the US, that's hardly enough to cause a "global deflation" rate.
Alibaba, are you talking about the "wholesale" alibaba that doesn't compete on the same market as Amazon, or are you talking about Aliexpress which sells little irrelevant things?
You see, online shopping needs a credit card. That's the default. The de facto standard. But that's not something everyone has. Just a fraction of people in developing countries have a credit card, and of those people, an even tinier fraction have a "international" card (most VISA issued in my country are only for use in Argentina for example).
Amazon is irrelevant in Latin America, Africa and huge parts of Asia. They are not having a global effect.
Heh, here in taxland (Argentina) we have tax on deposits. 0.6% of every deposit in any account. So if someone deposited 1M in your account and removed it, you'd still get taxed $6K.
In Argentina there is no "clear mistake" option. The seller is obligated to sell the product at whatever price he put in the price tag. It doesn't matter if it was a mistake. Learn from your mistakes, I suppose.
I filed a claim against a seller for precisely that. They were selling a machine with 64% discount. I paid for it, then they canceled the order. So, I filed the claim. There was no mistake, though. It was labeled "HOT SALE". So if they advertise "AMAZING DEALS" and one product is 64% off, then it's most likely NOT a mistake.
what's the point, really? The only victims here are people who aren't responsible for this. They're left without internet for days until this is fixed. Yes, we know shit is insecure, but take it on the people responsible for this, not on the users. They will still be billed. And no one will be fired for the mistake.
I get clients all the time asking "if I could just fix this computer so they don't have to buy a new one". Open it up and it's bad cap after bad cap.
Besides, I just fixed a XPS420. It struggles a little with modern websites but it's fine. It's not "perfectly" usable. It's just "usable". Until you want to fullscreen a HD youtube video, of course.
A nationwide ISP here in Argentina, back in 2004, was assigning a whole/24 when you got their "gold" service. It was 1mbit, guaranteed, all business crap, and came with a/24. One day one of our servers stopped responding to the internet. Without any warning, they cut off the/24 to a more sensible/29... and my server was in.200/24. I had to give instructions to a field tech there to change the IP to.2 to get access back...
So now McDonald's does it, but not to themselves but to every other indie restaurant and small chain. And blocks them off the internet. Oh but you didn't think about it, did you? How can you quick so jump into the CENSOR ITTTTTTTTTTTTTTTTTTTTTTTTT option?

Peering is not always free, you stupid fuck
Good thing you're not a researcher.
That's why Starbucks is a global corporation and you're here on /.
The wifi provider, Fibertel, is one of the country's largest ISPs and the largest cable operator. It's the argentinian equivalent of Comcast.
Yes. https://www.fool.com/investing...

amazon is not "significant" outside US...
What the hell are you smoking?
Walmart is global. They're everywhere. They are HUGE in China.
Outside US, Amazon is tiny. In Asia they are just irrelevant.
You see, son, you think only USA and Europe matter. But you're wrong. Set foot in Asia and see where the future is.
I'd risk saying neither do.
