If there's no air in the tube, how do you breathe? I mean, there is air in the capsule but I assume that is finite. So how do they refresh the air and what do they do if there's a rupture?
I'm in a rural part of the country. I have a 900mhz antenna that points to an access point (2 miles away) across the valley (through 150' Doug fir trees) and the access point relays to another tower which connects eventually to the ISP. (00Mhz bandwidth is limited - I get 4Mb on a good day. But it beats the hell out of dialup.
Curious.. how is the access point managed? A friend who lets you connect, an ISP account on a utility pole?
A business that sells a million dollars worth of merchandise is not a "millionaire" business. A "millionaire" is someone with a net worth of greater than a million $currency.
A million in earnings takes a lot more than a million in sales. How much depends on product and margin. Most big Ebay sellers have tight margins.
Google should approach MS, Apple, Facebook, and Netflix and suggest that they invest into Google Fiber.
A wireless solution would be easier to implement if one existed. Right now, the only option on my mountain property is very weak cell service or satellite internet. Both costly and very limited in bandwidth. Fiber would cost a lot to run.
Those people are idiots. No one should give one shit about the desert, except that we shouldn't go forth and spray it with depleted uranium which will create a problem for us later. It doesn't matter if nothing lives there, because that wouldn't affect things in nearby biomes. The biomass is so low there (like a rock, it's just about all silicates) that the relevance is near zero. All we should care when it comes to deserts is their extents, and not polluting them.
But your opinion doesn't matter as it will become an issue if large swaths of desert are used for energy. There will be those that care. Even if it is just the added cost of dealing with the legal fights and environmental studies required for each siting.
I could give you a million places to look where you could peel back the veil of abject poverty and see the new slave class this country has embraced,
"embraced"? Just because something exists doesn't mean it is 'embraced'. I guess we've 'embraced' wife beating as well, cause if you peel back the veil......
But you are right, we should be more like those countries that has no lower class producing products that are consumed by the more wealthy. Which country was that again? I like how people ignore the entire history of human civilization and blame our social makeup on the people doing the best in it today. I'd rather be a poor person today than a middle class person 150 years aqo. Its an oversimplification of a human condition issue, and it leads to oversimplified solution propositions like this tax.
So 100 companies are drilling oil, digging up coal and then just burning it off to produce CO2, eh?
Of course it's from the Guardian, one of the more hysterical of the Climate Change Drama Queens.
Since most emissions are the result of petroleum usage, and since the global petroleum businesses have consolidated into smaller number of major players, the 'finding' makes sense, that is if you blame only the supplier but not the end user for all emissions. But so what? Would it be better if the same amount of emissions came from more companies?
There may not be a lot of retail market where margins are thin and development costs are exorbitant, but industrial market for VR is booming.
This is where VR progress makes the most sense in the near term. There are many useful utilities for VR, particularly in design. This is an area of advancement where 3D tech had already been proven quite useful. Being able to 'walk thru' industrial structures before they are built allows the designer to notice things they might not otherwise.
For the home user, the cost of the gear, plus the host computer, just doesn't justify the experience for gaming for most people. And there is just a lack of content to drive non-gamers into the market. If I could sit in a really high quality 360 VR film of the earth's natural wonders for example, or attend a concert, I might bite.
Not all the power plants. But you are right. These units would also use electricity from the same CO2 producing plants, a little bit less for most of the time, more when extreme temperatures are reached. But regardless, the summary said the CO2 comes from the buildings, mostly that would be from gas, wood, or oil burning.
Whether you believe it's a misnomer or not, DRM usually refers to "digital rights management" instead of "digital restrictions management" like what's in the summary. The summary reads like propaganda and is full of rhetoric. Slashdot used to actually be a news site, hence the former motto of news for nerds, stuff that matters. Now, it's run by terrible editors and spews propaganda. Slashdot loses credibility with nonsense like that. The management and editors are doing a wonderful job of running this site into the ground.
Maybe we should have a 'Day against Slashdot clickbait' and not post to any clickbait headlines (which is running about 90% now)
It makes most sense for any home where a heat pump might already be an option, places where AC efficiency struggles with very high temps or a heat pump struggles when its very cold.
However, this statement from the summary is stupid;
Geothermal systems are better for the environment because they significantly cut down on carbon dioxide emissions... Buildings are responsible for 39% of carbon dioxide emissions in the U.S.,
Air conditioners and heat pumps don't emit CO2, nor do electric heat strips, nor is all that emission amount due to heating and cooling. Simply saying they are more efficient would have been sufficient.
Renewables have already flattened off the CO2 emissions curve, and from here on out, the CO2 emissions curve will go down.
No. Another increase is predicted when they bring the next nuclear unit offline, and then each unit after that. 'Flat emissions' are as much or more a result of efficiency gains and economic slowing than anything.
How do you know this? If a child is attending daycare, school, there are times when they see their teachers more than their parents. Especially if the child is an only child. At what point is an only child supposed to be taught to share their toys? At home when there is no other child to share?
So you are asserting that teachers have more influence over a kid's behavior than the kids parents? I think its pretty easy to see how things work. A parents influence starts right after birth. Well behaved kids are typically that way before they ever enter school. Any given teach spends relatively little time with a kid compared to their parents. If parents are not spending time with their kids, and not letting their kids interact with others, they are putting that kid at a great disadvantage.
Their existing warranty appears to guarantee 70% remaining capacity at 10 years for Powerwall. We'll have to see what it will be for grid storage. One article I read said 5-10 but I can't find it again. It would make sense that a grid system would undergo greater deep cycling than home Powerwall and therefore have a more limited life.
As usual with Musk announcements, a lot is left unclear. It seems the quoted price may not have included transportation and installation. And the discharge capabilities are still unclear as well. If max power is 100MW, which is at full charge, what is output during the discharge cycle? It will reduce below 100MW as it discharges. Is 129MWH accessible storage or max (you don't want to fully discharge Li-ION batteries)?
Bottom line is that battery is very different from a gas plant, and comparing ratings is apples to oranges. The power from the battery gets 'paid for twice'. Once for generating it, the second for cost of storage.
The stock was trading on the open market around $35/share and Amazon spent 20% over retail ($42/share). Seems like Whole Foods "won" the negotiations to me.
That's about normal for this type of buyout. Imagine how the shares would have spiked had word gotten out about an Amazon buyout. Hence Amazon's silence dictum.
But the question is, what did Amazon want out of Whole Foods?
I haven't been studying this one much, but my sense is the most compelling thing about Whole Foods would be its size and footprint. While many grocery chains have stores in as many marketable locations as they can, WF has been more selective by necessity, they have about 450 stores in total, big enough to be important, but not so big as to make fundamental change harder or riskier. I'm sure there are a wealth of other reasons, but I bet size was a big factor.
The air gapped systems are at risk though. As we saw in Iran and in leaked documents from the NSA, there are ways to cross that air gap. Infected USB media, for example.
Very true, which is why a full gamut of other controls are in place. Air gap alone is not sufficient, but it is a central piece to making intrusion extremely difficult.

Of course not, but what is your "solution" to this problem? Have all the oil companies just stop drilling? Let's see what happens then.
That's my point. The 'solution' has nothing to do with the number of companies responsible for most emissions. That number is irrelevant.
Those people are idiots. No one should give one shit about the desert, except that we shouldn't go forth and spray it with depleted uranium which will create a problem for us later.

a min 20k investment for 50k+ added (equity, im guessing ) in your home. not a bad idea.
Yes, you are guessing. Why would you think that? My guess would be around $5-10K improvement in market value.
