You would have to get it up to a high enough temperature to stay molten throughout the night, while still providing power. It's a lot more practical to use other solar technologies for home use and keep these ones in big arrays. It's a bit like why power plants will always have higher efficiency than home generation, it's a matter of scale.
They didn't have the desert sun pouring onto a thousand large mirrors perfectly aligned on something for hours on end. Their test was more about the ability to align all of these mirrors without technology. These kind of things are dependent on energy going in vs energy going out. A thin sail surrounded by cool damp sea air only being shone upon from one side is going to have a lot less energy going in, and a lot more energy going out than a desert solar array.
If you do so in an attempt to harm or otherwise deny access, then yes, it would be. It's more akin to getting a thousand people to sit outside their building and forcefully block anyone who tries to come in.
This is on a completely different level though. The only people that have anything to do with BGP are the ISPs themselves. BGP is only used to route from groups of routers to other groups, where a single organization owns the entire group, and they're sending to the group of another organization.
Perhaps, but what choice so we have? Once we run out of v4 addresses we have to do something. Also: IPv6 is initially allocated via geographical areas.
More importantly, it doesn't matter how sparse the table is as long as each section is contiguous. If I know I can send any traffic from (made up protocol) hosts 1 to 1000 to router 1200, and any hosts from 10,000,000 to 10,010,000 to router 4500, then my table is just fine.
As the life of an address space goes on it will tend to become less compacted, switching to a new one that is huge will make a sparse, but compacted table.
Hamachi is built on top of IP, but I don't know exactly how it works. Once the data leaves your machine the network will treat it just the same if it's hamachi traffic or not. If you can reach it via IP, you can reach it via hamachi (excepting IPv6 support, dunno where they stand with that).
Put simply, the way a transistor works requires the use of semiconductors. It's a property other than resistance which the transistor requires. When not in a transistor, materials with a high conductivity are used.
For physical products then wouldn't that be Walmart stealing? Or at least a breach of contract. If Walmart had a contract with the manufacturer saying that the manufacturer would be paid when the item is sold, and Walmart doesn't pay... The manufacturer doesn't have any right to ask you for money. You had an implied contract when you bought the item. Walmart has an contract with the manufacturer. You have no relation to the manufacturer.
Services are a little different as it's a continual transaction. At most when Verizon doesn't pay DirectTV it would cause a breach of contract between Verizon and DirectTV. DirectTV can then turn off your service causing another breach of contract between you and Verizon. DirectTV billing you should (in a rational world) be illegal, you never had a contract with DirectTV.
DirectTV can ask, but they have no right to demand payment. I'm not saying you weren't billed by them, but if I couldn't get them to withdraw the bill I'd just ignore it. Anything beyond that is stealing.
The oil being collected is generally very heavy, but can vary in composition. Oil of that type cannot be used in any normal type of combustion engine. That limits you to engine that rely solely on difference in temperatures rather than ones that try to control combustion. You could run a sterling engine off of this, but you have to consider what happens between oil slicks in the same area. If the slicks are too far apart, your robots run outta energy and just sit.
Solar energy on the other hand will always be there tomorrow. I don't know what conditions are required for these bots to get enough power out of their solar panels, but if it's cloudy and they can't do much you just have to wait a couple of days.
Well that critical mixture is more of a range. It doesn't have to be a perfect mixture, just close. There has to be enough combustible density for ignition energy to pass from one particle to another, and enough oxygen density so that the combustibles can cause combustion. This is close to how a fuel air bomb works. However it's likely that the explosion heard wasn't directly related to the hydrogen at all. (skip to the 4th paragraph)
Note that the combustible density has to be high for stable/weak combustibles, or it can be lower for unstable/strong combustibles. Hydrogen is rather unstable (doesn't need much activation energy) and thus the particles can be really close, or relatively spread out.
Not all of the combustible has to go at the same instant, an explosion in one part might cause the density in another part to change, or could collectively give enough energy to cause ignition. Some things not normally considered explosive can become explosive if given the proper conditions (including a pressure vessel). Sugar dust, wheat dust, flour, and sawdust have been known to cause explosions in very rare conditions.
A pressure vessel failing is essentially an explosion, so it could be that the tank failed, and it just happened to be filled with this flammable gas, which then caused a fire. An explosion in the tank is nearly impossible, simply because there is no oxygen. Most combustibles need some sort of a pressure vessel to cause a proper explosion, if the ignition velocity is not fast enough, then it will cause a big fireball (think Hollywood explosion) but won't cause much explosion damage.
The real safety problem with using compressed hydrogen as a vehicle fuel is that it is a compressed gas. Even if a tank failure doesn't cause a lot of damage, the hydrogen will come out very quickly, leading to a possible fire. This isn't a problem with gasoline as it is a liquid, and on top of that only the vapors are really flammable. I don't know the safety ratings on a hydrogen tank put in a car, but the tanks would have to be done very well to be equal in safety to a gasoline tank (which can have inner bladders, that don't work with compressed hydrogen).
Hydrogen stored in metal hydrates is very stable, and easily safer than gasoline. But I don't think the energy density is high enough yet for practical use.
This post ended up being a lot longer and more of a ramble than I intended, sorry.
If the gasses are heaver than air, then they might have been putting them out of the stack, or it may have been impossible to. A stack only works if you can force the gasses out, however being heaver than air, you have to heat it up (to reduce the density) to get it to go out the stack. Once it goes out the stack and cools, it might just fall down anyways.
If they vented CO2 then it would probably be hot enough to vent out of a stack. CO2 is probably classified as a poisonous gas, as it has to be at only 6%+ to cause major harm, instead of simply displacing the oxygen like a non life-sustaining gas would.
For a lot of cases, there doesn't have to be a reason to be depressed. Back in high school I was depressed (and still am fighting with it) but there really isn't any reason for it.
It doesn't reduce the pleasure received from playing video games, rather it works against the psychological addiction. It is already used as a smoking cessation aid. Doctors tend to be careful with depression medications given to patients under the age of 15, especially when it lowers the seizure threshold. Most parents would stop asking for it when told it can cause seizures (in ultra-high doses with patients that have a low seizure threshold naturally).
It's a lot easier to think of it as a gas powered turbine that doesn't use atmospheric oxygen for combustion. It also seems like they're somehow reacting the N2O itself, instead of using it as an oxidizer for another fuel.
90% carbon dioxide? 8 percent is lethal, and I haven't heard of anyone dieing from breathing someone else's breath. Breath is actually about 4% carbon dioxide.
The bigger deal with breathalyzers is that they make an assumption about the rate at which ethanol diffuses from the blood into the lungs, which I've forgotten the units for, but could easily vary from 1200-4200, with some outliers of 900 and 5000.
Space doesn't really have a temperature. Temperature and conduction of heat requires particles to bump into each other. You feel something being hot because the molecules in it are moving very quickly. You feel something being cold because the molecules in it are moving slower. However in space there are (almost) no molecules.
Thus the only ways to lose and gain temperature are via radiation (not necessarily ionizing radiation), and internal heat generation. The sun is radiating energy onto the satellite and the satellite is radiating energy. However as the satellite isn't very hot, it doesn't radiate a whole lot, thus is tends to heat up.
All of the electronics on the satellite are producing heat as they work, and I suspect that this is where most of the heat of the satellite is coming from.
This isn't all that important for most satellites as they can work at higher temperatures, however the sensors on the WISE needs to be kept cold. Since the sensors on the WISE work in the infrared part of the electromagnetic spectrum, and all things radiate infrared (unless they're at absolute zero) if the sensors are too hot, they will just detect their own infrared radiation rather than the radiation from the objects in space.
No, as they went out and found the torrent files themselves, which while blizzard uses the bittorrent protocol, it doesn't use the files. A torrent file is just a list of trackers anyways, so instead the probably put that into the code or a config file somewhere.
To shorten your post: AIs will exist when a computer can write code for itself to run without interaction from a user. Given a problem, and having no prior knowledge of a solution, nor a way to arrive at the solution, an AI will be capable of creating a set of instructions to solve that problem.
While I agree with you that cybersquatting is generally bad and needs to be fixed, it's not extortion. Extortion generally means that you're being asked for an excessive amount of money for continued operation, not expanded operation.
The "law" of gravity is really just a theory with a lot of support (experiments) to back it up.
I don't disagree with most of your post, except for two points. One is that there is a law of gravity and a theory of gravity. The law states what the force of gravity is, and the theory states why there is gravity. The second is that the main problem with putting science and religion in the same room is when people try to use their religion to influence the conclusions of science, or more generally when people use their religion to attempt to influence others in an area other than strictly religion.
I think the reason some people try to use science to disprove religions is that other people try to use religion to disprove science.
At the end of the day beliefs should not be used to dictate reality.
One major thing everyone overlooks is the range of RFID. To be small enough to comfortably fit in a human only a passive unit with a small antenna can be used. This limits the range since the power has to be pushed to the RFID tag. You're going to get a range of maybe a meter.
Additionally no materials that respond to a magnetic field can be used, as it would tear out the tag during an MRI. From a security standpoint, want to become someone else? take their chip. After all, it's a perfect ID system, so if it says you're joe, there's no way you could be bob with joe's chip. (This is why there are photos on id, although it's much more difficult to steal a chip than a card)
I've also never figured out how they can listen to multiple tags at once, the same type of tag is going to be on the same frequency, so don't their transmissions overlap?
Finally there is no time when an earthquake is supposed to happen, except for aftershocks (in which case if the original earthquake is strong enough to warrant getting your tag, it's probably too late anyways)
It wouldn't be too difficult (relative to this) to make something that reacted to any DNA that's not eukaryotic. But chances are, that there are a bunch of different little bacteria going through your blood. These bacteria just haven't been caught by your immune system yet, but aren't really doing any harm. There's no guarantee that these pathogens even harm humans, just that they've somehow ended up in your blood.
Why do they even need people to look at these at all? The human form is rather smooth, and it should be simple enough to write an algorithm that detects anomalies and gives a human a picture of just that area. Or not even a picture, just tell the screener what area needs to be searched. If we are to believe that these scanners go all the way down to the person's flesh, then it would be nearly impossible to make any kind of weapon smooth enough to be undetected by an algorithm.
Additionally I hope that these scans aren't being stored. At most they should be allowed to be stored for a day, after that the person's been arrested and you can pull the scan from the system for evidence, or the person has already gotten onto the plane, flown, and landed on the other side.
One of the basic concepts in physical security is having the 'key' be in two parts, something you have and something you know. The idea of the debit/credit card is that it needs to be physically present in order to make the transaction, but that has gone away with online purchases.
There are two major fixes that could solve a lot of these debit / credit problems. One is to have the number on the card be different than what is stored on the magnetic strip. This way, when the thief gets a hold of the data on the strip, they have to make a new card and can't make online purchases. It's not difficult to make a new card with the data off the strip, but it just makes it that much more difficult, especially when the thief goes to use it and the merchant refuses because it's a generic card and not one from a bank.
The other major fix is to put a time changing number into the card. I can't think of the right word, but it would be a digital display with a number that changes every so often, anywhere from 5 minutes to a day would easily work. The bank knows what that number should be at any point in time and that particular card knows, so now you really do need the card in order to use it online.

Assuming you know which numbers are pressed you don't know the order. ...
4 digit pin = 4 factorial -> 24 permutations
5 digit pin = 5 factorial -> 120 permutations
6 digit pin = 6 factorial -> 720 permutations
9 digit pin = 9 factorial ->362,880 permutations
It's pointless to bother brute forcing it beyond 5 digits, since you have to manually input the digits.
