Burning Coal yields pure CO2(in theory), burning CH4 gives you CO2 and H2O
Burning coal:
C + O2 -> CO2.
you're confusing coal with graphite or something else composed of elemental carbon. In fact, coal is just a huge mass of hydrocarbon chains just like oil, with a whole bunch of other nasty stuff thrown in like sulfur. it's not as simple as C + O2 = CO2. It's more like CxHy + S + O2 + N2 = CO2 + CO + NO2 + SO2 + misc other stuff.
Wind and nuclear I understand, but how does gas significantly reduce carbon emmissions? Isn't it still burning stuff and thus producing CO2? How is gas better than coal in this respect?
natural gas power plants emit half the CO2 of coal power plants, if you trust those commies at EPA:
At the power plant, the burning of natural gas produces nitrogen oxides and carbon dioxide, but in lower quantities than burning coal or oil. Emissions of sulfur dioxide and mercury compounds from burning natural gas are negligible.
The average emissions rates in the United States from natural gas-fired generation are: 1135 lbs/MWh of carbon dioxide, 0.1 lbs/MWh of sulfur dioxide, and 1.7 lbs/MWh of nitrogen oxides. Compared to the average air emissions from coal-fired generation, natural gas produces half as much carbon dioxide, less than a third as much nitrogen oxides, and one percent as much sulfur oxides at the power plant.
The average emission rates in the United States from coal-fired generation are: 2,249 lbs/MWh of carbon dioxide, 13 lbs/MWh of sulfur dioxide, and 6 lbs/MWh of nitrogen oxides.
note that this is just at the smoke stack, not addressed here are emissions from extraction, refining, and transportation. I have little intuition of the magnitude or how coal stacks up to NG in this regard, other than in CA for natural gas fueling stations transport can add 10-25% more CO2 depending on the source (i.e. domestic pipeline, international shipped to US, international shipped to mexico then pipeline). http://www.arb.ca.gov/fuels/lc...

short answer, you can never know that the phone has been sanitized. First, you'll never even know if you've been infected. Then, even if you go back to a full phone wipe, who knows what was planted in the BIOS or something. Basically, you have to throw out the phone, because it's been pwned 4evar.
actually, it's not so much about being domestic or international as it is where you build your shizz. Car manufactuirng is exploding in the South, across KY, TN, AL, and many other states. it's all the major companites. toyota, honda, hyundai, GM, Mercedes, BMW. The plants in the south are non-unionized. and its especially appealing for foreign automakers cuz then their cars are "made in america" for the purposes of taxes and international trade issues.boeing also wanted to move from WA to the south, I forget where, but the thing was held up because the unions went to Obama. I forget how that turned out.
simple fact is, it's hard to build cars in the midwest, nobody wants to do it. a lot of legacy stuff is there, and a lot of things are bound by contractual relationships and institutional knowledge, but if you're starting fresh then might as well put the plant in the best location.
Actually the FUD is in the summary, where it says that android and iOS phones are vulnerable. it's more accurate to say androids and jailbroken iPhones. if you haven't jailbroken your iPhone, then according to this research it is not vulnerable. This is just anti-apple FUD to tear them down.
in terms of avoiding malware, the suggestion "don't jailbreak your iPhone" is actually an excellent suggestion. Kinda like a strategy to avoid STDs: "don't sleep with whores". for all that slashdot raves about the safety of open source code etc, you think there would be more caution about running unknown code from unknown developers whose purpose is to override your phone's security settings.
iOS malware only works on jailbroken devices!! FTFA:
Taking a deeper dive into the malware, Kaspersky and Citizen Lab learned that the iOS version of the RCS Trojans hits only jailbroken devices. Pristine iPhones are also vulnerable if an attacker can remotely run a jailbreaking tool such as Evasi0n and then load the malware implant.
So I know there will be a lot of shouts here of 'see! iOS is vulnerable just like android!" this only works for people who have chosen to expose themselves to malware. also raises a lot of questions about who are the secret teams behind these jailbreaking kits. Especially with the new news of the new jailbreaking kit out of china.
I don't understand, if the devices are affixed to poles, how will they be able to leave chemtrails around? I'm still wearing my tin foil hat just in case.
The relationship between the United States of America and Internet is like those of a landlord and property renter
true true... one of the most insightful comments I read on slashdot after the snowden thing was that we should all act as if the internet were a military installation and we were guests.
your "ideal" solution is also very expensive and time consuming and hard to use. I could go to the apple store and come back with an arm full of drop cams and set them all up while you're trying the IP bandwidth routing issue on your "ideal" system.
i think that the definition of ideal changes on the situation. What situations require a camera that records to multiple local and remote destinations not fixed to a central service?
problem is if one solution is good for everybody but google implements boringssl in all their services and products, then everybody will be using boringssl regardless.
I disagree. spend a little time to think about your path then dive in. example, I needed to pick up a language for simple scripts, choosing between php and python. PHP was simple to install through an XAMPP php/apache/PHP package. so i just dived in and did it.
retrospect, I wish I had invested in python instead. Now that I can use PHP I'll just make scripts there, but python could have been so much more potential for other work.
that being said, I recommend swift, apple's new language for iOS apps. It's got a really nice IDE, it's pretty much tailored to people making games. you can get access to all the gaming power of the iPhone, and not have to worry about other PC headaches.
the main unsolved problems with fuel cell vehicles are:
* demonstrating fuel cell stack life
* finding a better way to store hydrogen on board (more dense)
In terms of how you make the fuel, all of this is solved. when you say "one problem is the fuel" I wonder what problem you are defining specifically? It's unclear.
you call out the expense of catalysts, without any knowledge of the expense of the catalyst or the amount required. hint: catalytic converters also contain platinum, but somehow science found a magic way to make them affordable.
then you make a tesla comparison, sounding like a fanboi. OK, we can weigh it up against a model S. what metrics are we using?
your whole post is FUD of the highest order. I think MS is hiring.

No.
this is the most controversial issue, yet wasn't even touched in the summary cuz of the fantards.

Contrary to what the summary says, I'm pretty sure when you install unix your social rating goes down, not up.

don't jailbreak, don't get pwned.

that's what she said!
also apparently the minutemen soldiers spend the day jerking off or something like that.
actually you're right that's extraordinarily apt. +1.
yes cuz every american city would melt, concurrently with every chinese city.
celebrate now, but this sort of thing can have unintended consequences... such as when the layoffs start? that will blow chunks.
ur mom is faster than setting up a drop cam.

FCBs are much more prevalent in Europe than USA. USA has much higher needs for power, while Europe is gentler. Source: it's my job.
