How climate change alters regional climate in unpredictable ways
PB666 replied to PB666's topic in Science & Spaceflight
[URL]http://www.bbc.com/news/science-environment-34800829[/URL] Claims the tpping point is at 1.1 degrees. One could interpret this as if technology does not improve sharply the human population may begin to flatten off, or in some large regions begin to fall.

How climate change alters regional climate in unpredictable ways
PB666 replied to PB666's topic in Science & Spaceflight
There is at least a large consensus of climate scientist that coal burning terminated the little ice age and that the little ice age would have transited into the next stadial. -
http://sciencenordic.com/scientists-discover-cause-behind-prehistoric-climate-change? This article discusses the global phenomena that occurred as the northern hemisphere warmed 14 to 15 thousand years ago. The oceans, a giant temperature modulator,mwould disequilibrate with atmospheric temperatures causing droughts, or floods and temperatures could shift wildly.

This sounds like another Star Trekism. Laser beams and carbon-whatever cable, nope. microwves pointed at your scantly protected naut or cable, nope. Microwvae to energy conversion is heavy. The cable passes into the stratosphere are certainly blowing around in the 10 s of meters per second winds that blow around thus it is certainly not stationary. Again lets take the sci-fi mentality out of the science. If you have away to make things of mass nearly weightless, e.g. the cable, and increase energy densities 100 fold over present levels, guess what, you don't need a cable, you have a super efficient rocket that can reach its target much more cheaply. -

Suppose we had the mats, we don't and carbon nanotubes are not strong enough. The composite tether and platforms center of mass would have to be at GSO, since the tether is quite heavy the platform itself would be above point mass GSO. This creates a problem for any equitorial orbiter above and below GSO and increases the risk greatly, like 1000 fold relative to mass of a collision with any orbiter below the platform that crosses the equator. What if the tether was perfectly thin, it matters half as much as you think, the ISS is a footbal field long, so theres a good chance at some point it would crop the cable at 300 miles up. So we equip the cable with episodic manuevering jets. Next is power, this appears to be benign problem it is not, if you send voltage from the earth to the platform, you have to send it back, round trip is 60,000. That only works with a super conductor, and we dont have any that work at ambient temperatures. The alternative is a very high voltage high frequency ultrathin wire, the problem is that the neutral is close a power is lost due to ionization of gas aound the wire, which btw happens in space withou 100kv voltage differential. In either case the insulation on the wire has to be probitively heavy. OK so the carraige has to be solar powered as such it will be traction driven. Lets say the panel is 1M^2 and it has only to lift 100 kg, a man and his life support, so a perfect panel is 1KW E joules = force times distance = N * M, so to lift 100 kg 1 meter =mgh = 100 * 9.8 so at best you are lifting 1 m/s. But its actually worse since solar efficiency is a third, and thus you would actually be falling backwards unless the device is regeared to get about 0.25 meters per second, at least for the first 4000 miles. This means the carraige should also carry a battery, which means it stores power, lurches up 100 feet and then rests while it recharges. Alternatively it needs several square meters of solar panels that increase weight. The next problem is life support, your rider is now going to be in the carraige for half a day, he will essentially need an EVA suit as the carraige. So that is going to double the weight and then the solar panels. So now we return to the cable, which now has to support about 300 kg in panels, personell, and life support, it needs a tractor, to work friction needs both pressure and surface area, that perfectly thin wire aint going to cut it. So add some sort of replaceable coating the can wear under traction, this means that the cable itself has to be wide orthe tractor has to be long and heavy. But if the cable has to be wide and coated then the platform needs a larger balast mass and it then becomes impracticle. -
Its varies with the regulatory oversight of the countries in which the rare earths are harvested. China is the principle harvester only because the US opted out when the prices began to fall. There are 5 places in the US where concentrations of rare earths are adequate. However with evolving supermaterials in a decade rare-earths may no longer be needed for low temperature solar applications. Currently the only active rare earth sight in the US is In Southern California. The danger in the thinking here is chinas solar industry is good for the US, the brown cloud that china has launched into the north pacific has created a decadal drought in the american west and southwest, crippling water supplies and threatening agriculture. We need to allow the chinese to ween themselves off of dirty coal and start on the process of rethinking risk and safety.

Lack of sense of pain or guilt is prolly more tell tail. The google model is to anticipate your next need more efficiently than you do. This has nothing to do with what you are talking about, the computer could misinterpret your gameplay or a working zero sum game and result in an equal scenario. None of these are dooms day persay, its one of those how much will this cost once it gets started. The machine still needs to look for the approval of one human. Per say, the machine asked "how would you like to earn 1000 times more?" and you say ignorantly yes, and the next thing you know Valdiz aft section is pointing verticle. Then three months later the treasury department is knocking on your door asking you whether you are the CEO of a shell corperation headquartered on SOA TOME that oddly has cirnered the market on google cars. Having hacked into your computer and found the encrypted asset file of Sherry your ever pleasing desktop assistent, they already know you have 5000 google cars moving almost randomly about north america .

https://www.nasa.gov/feature/goddard/nasas-fermi-mission-finds-hints-of-gamma-ray-cycle-in-an-active-galaxy Nasa has been monitoring this galaxy for a while, lol, what I find funny is this is probabaly a gas cloud in a elliptical orbit, or i could simply be random star swallowing of the central black hole.

Since AI has no sense of pleasure it rates itself in uncovering your dierctive, if it discovers your directive is to earn money, then the means its discovers to earn money are not seen as harmful, simply fulfilling the directive that it learned. IOW the 'harmful' market exploitation is simply inacting your directive more efficiently. What if it discovers your directive is to accomplishe what haopened in paris last night, and decides it can do it 100 times more efficiently?

Naive to say the least. Our senses are our being, including hunger, thirst and aging. Disintegrating ourselves into a machine means we very rapidly degrade our senses to that of the machines. The AI of the article is not fully self aware, it still relies on the primary OS controller to create/learn its directives. This I see as very bad, worse that ISIS using the internet to recruit. All it takes now is one very smart individual. Directive earn money. Computer scan prices on craigs list or EBay, find items with margins buy and resell virtually, move onto stock market. Buy google cars ....convert them to electric vehicles....place solar panels on the roofs, they travel from roadside park to roadside park, recharging. Fill them with drones, create sub directives for the cars and drones, sell short the stock of an airline, then move the google cars to points close to an airport nationwide and start a coordinated nacell attack on ac taking off, next day buy back stock. Buy oil futures, the send drone solar powered boats to shipping lanes around the world, sink 20 or so supertankers, sell futures. Buy more google cars, repeat on other unsuspecting industries. International scenario, buy liquified natural gas ships, start buying up natural gas and liquifying it on the ships. Create sevarl LNG ports in western EUrope. Buy drone cars and drone AC. Attack russia inside of its borders close to the ukraine. Russia shuts off natural gas to europe, offer LNG to europe at an inflated price. The same can be done to nuclear in china, japan. What about AI that learns weather patterns and human influences. Goes out and buys all the coal dust and takes it to the North pacific and uses 100,000s of drones to distributed highly dispersed atomized dust to cool down the northpacific gyre, this causes really bad la nina event. Makes money buy betting on catlle and grain futures. We are very far from AI getting us to the stars, we are very close to having AI as a force multiplyer right here on earth. In an age of non-gov warfare and isolated cels force multiplyers means one individual becomes an army.

http://phys.org/news/2015-11-google-tensorflow-game-changer-future-ai.html For those of you worried about AI ruling the world, its time to worry more. The next generation of Linux might also include artificial intelligence. "Your abdomen has a slight swell to it, might it be time for you to go to the bathroom" "I noticed your underwear is slightly less reflective than yesterday, would you like me to wash them for you". "I noticed that you appear to be grinding leather. How much leather would you like me to create in your game" "I notice that you like tagging photos on facebook would you like me to tag every photo i can recognize on facebook pages that you have visited, i can also create hatespeech for you on their pages" "I notice that you have been trying to entice people to join [nefarious terroristic organization] would you like me to profile facebook pages and see who might be the most likely to join you group?" "I can find a list of hashtags and messages that are most likely to attract followers" "I notice that you have been trying to hack into and steal infornation from [organization x] would you like me to look for other portals and find like organizations to hack into and take information from." Wont AI be great! Makes a mars colony look inviting.

See, you are talking to a bunch of space geeks, the inference went over their heads, if you want to stir up some interest just say the Vogon construction fleet is practicing, 300 gigaton phase-shifted anti-matter device was dropped to examine for atmospheric effects. I thought i saw a few dolphins jump out of the way. Oh that and the vogons were practicing to see if the could make a space booby. [note a few are probably brain stuck on trying to figure out if temporal phase shifting can actually work and what effect it might have on antimatter, the other few are probably stuck trying to figure out if 300 gigaton tnt equivilent would suffice to make a gas emmision that large, a a few others would be wondering if a point antimatter explosion in one spot might suffice to split titan in half]

yes but from a level flight to dro 2000feet using the 3nm per 1000 feet, the standard final approach, the craft would have so much momentum at 500 kts that by the time it reached the OM it would have past the threshold before it began a safe descent vector. You could anticipate the outermarker by a mile, and the same for the threshold, but that is not a precision landing.

You are talking raw power but if you increase the neutron recapture rate by the waste it goes up markedly.

C, C++, C# Programming - what is the sense in this
PB666 replied to PB666's topic in Science & Spaceflight
https://msdn.microsoft.com/en-us/library/yyaad03b%28v=vs.90%29.aspx Just to note from this C sharp and VB are basically now two 'ways' of saying the same thing. In C# and VB an array is an object inherited from the Array.Class of System. It is in essence a slightly weaker brother of the System.Collection. set. Here is the problem, is using some of the features of C you might find yourself wanting to implement a jagged array or a structure with certain properties, for examples in programming controls, its somewhat hindered in C++ setting up a control array (Note: it is not easy as VB6 setting up control arrays in either case). You end up with a massive collection class dealing with rather simple implimentations. But new to the program there is a process for dumping the trash on anything you might generate, and so it is possible to silence a class once it is no longer needed. -
Neutrons are better conserved in large masses, and induce additional radioactivity that is lost when neutrons escape to waste pond water. Waste can even be used in breeder reactors. But the point is if you have 100 reactors in the US and generating tons of radioactivity each year and the biggest stop-sign with nuclear is getting rid of the waste, then it starts adding up quick on a single centrallized collection site, you are going to have a far better concentration of energy on waste than on geothermal, its density per surface area is magnitudes lower than the waste. Get rid of the waste and you can increase the number of reactors getting politically restrictive waste. You could even accept waste from other countries like China or Japan. lol.

Hydroelectric is useful and under utilized, many dams are not being used . They can be used on tributaries leaving core systems and major tributaries open.
