1.) Tape is fast - your sata2 hdd will hardly be able to support a steady flow of data to an LTO5 drive (SAS 3/6gbs) Disadvantage - no random access but that's not what tape is usefull

Ok, will China go to war ? I think there is no default choice here, because chinese rulers decide a bit machivellistic, and therefore they have recognized that China cannot sustain it's own growth of population, wealth(=CO2 Emission), industrial production(=Self polution) these factors lead to social unrest and this is the last thing the rullers want. Looking back into the past(Tienamen Square Masacre) there is a chinese solution to social unrest - use the patriots view and direct it to an outside scapegoat / enemy.
Japan is the enemy number one, also for historic reasons - japanese nationalism has done it's part in the situation we are in now (masacres, rapes, torture / WWII) and Japan is an easy enemy because on the one hand it's military force is specialised in defending(the main islands) but what comes in handy is the blood & death bonding with the U.S.
So in reality China wants to demonstrate strength against the U.S. and Japan comes in second(Shinzo Abe - tries to alter the "National Defense Force" into a "National Offense Force" and what gives me the creeps is that Japans tendency for nationalistic thinking is very similar to the chinese view.
China is in a deadlock situation for it's ambitions as a regional superpower, from the military capacity they are. (Nukes, Missiles, Destroyers, Subs, (experimental)Carriers)
The deadlock consists of Japan: - Japan is under direct U.S. protectorate, if China attacks, U.S. are about to react. - China must find out if the U.S. will react or just play the non aggression card and give up on some rocks in the boiling sea
Taiwan - U.S. allies - like swizerland - if someone attacks, they will secure the country by trip/tank mines and asymetric tactics, the only chance to win for China without paying an extreme death toll would be to blast Taiwan of the earth (Nukes)
Vietnam - they don't like China, and feel threatened by China, espicially when China held back some good for vietman during the war
Philipines - U.S. allies
And well those deserted rocks in the boiling sea are the weakest target, but are a lithmus test for the unconditional military support for Japan to be supported by the U.S. But if China's leaders don't watch their steps closely they could really "kill everyone in China".
1.) he was someone especially motivated by power and manipulating others 2.) MAO-A gene that has been linked with aggressive behavior 3.) is family line included seven alleged murderers
It's not all bad genes, but his genes affect his behaviour pretty strong, and the genes(family line) increase the chance of turning into a murderer.
The question is when will the trigger level be reached where he cannot suppress the violent tendencies and go postal. Yes he might have learned to emphasize or simply learned to emulate it pretty convincing. And there is another question perhaps some folks at slashdot don't have the mild form of asperger but are just psychopaths, and get into a rage like "Hans Reiser".
So psychological conditioning is very important in these cases too, do you get a bonus for treating people in a human way or in an inhuman way.
- Is your peer group awarding you for helping someone or for calling someone a sissy, faggot or else ? - Do you get a bonus if you treat your fellow workers with respect or you just use their burned out corpses as a ladder for your own success
And well taking these additional thoughts into consideration - soldiers are trained not to emphasize with the enemy, soldiers being awarded for brave behaviour (brave=where mostly the basis is a good rage like killing spree) - amok runs like the one in washington are a consequence of this trained behaviour and genetic disposition.
And the major question is how would a psycho-scan of the GOP and the Democrats turn out, because if you recall the term "liberal sissy" it carries a very distinct aggressive undertone and aims at casting someone out of a social group, and these are sociopahs (read: "manipulating others").
It's genes it's the environment it's the education the question is is there any free will or just a trigger level a source and a drain ?
the main problem is that anybody entering slashdot.org in the addressbar expects to get the data slashdot sends, but as this MIM attack has shown, this data can be altered even for hand picked connections, these attacks were discussed in the past.
So we have a key problem here:
data transmission is compromised (yes even now it is compromised, because european traffic travels over great britian) - by this compromise I cannot authentificate that slashdot.org data is really displayed to me (I cannot authentificate that I really communicate with/.) - by this compromise I cannot authentificate that the data displayed doesn't contain an additional payload
the "solutions" in place to this day are
"https" - is compromised this will display a warning if the certificate does not match the domain, this solution however is compromised today, because if you have access to the private key you can fake the data as it is not encrypted. The private key exists in two places/. and the CA
Also your browser needs to be supplied with valid certificates (public keys) however if you take a look at what CAs issue these trustworthy keys you could leaving your door wide open won't matter.
Also if the ssl cipher used is rc4, well you don't even need to know the private key you just crack the communication.
"VPN" - compromised - needs a CA infrastructure - cisco
The solution to this problem are the tor hidden services,/. needs to start a hidden service
pro 1.) the communication is authentificated, as long as/. does not give their XD48484jdd.onion key out of their hands (vs. NSL) 2.) MIM attacks are possible but are extremly complicated 3.) the communication is end-to-end encrypted
Please/. just start a hidden service, and annoy those GCHQ guys.
Well, in germany anytime the industry announces to leave germany if they are remembered that they have social and environmental duties, but the first that tried this, came back to germany crying about unstable justice systems and unquallified workers, and concluded that they had spent far more, than they would have staying in germany.
Germany was dizzed by the US, for selling so many goods. I know that's because the industry fears..
And btw. there are many places like the examples are USA and Australia where the grid is worse than the german grid.
I think he will say: Integrating dynamic resource like the renewables with base load - notstopable nuclear power plants - results in a facility near the nuclear power plants where 10000 people start 1000000 2000Watt water heaters simultainously to evaporate the excess power nobody really needs.
that we would power our trains with electricity, but according to you this must be a hoax, I will take a train hop on the top and just test those insignificant "lines".
Ok, jokes aside, the railway is electrified, the locomotives using converter technology today are far more efficient than their diesel powered brothers. But the feasability of an electrified railway system depends largely on the climate and topological situation. But if you can electrify a railway system you can use long range trolley trucks, but investment would be needed yes, but if extracting hydrocarbons from crude oil or producing these from secondary processes(fuel synthesis) than those investments would be undertaken.
But you are right if you refer to long range or over the ocean transportation - ships - airplanes
Also but global transportation by ship, the average speed of the container freighters today decreased and is now the same as in the late 1800s of the sailing boats, cause reduce fuel consumption.
Also why I think civilisation will not collapse 1.) 7 billion people and 5 billion living between the middleages and the early 19th century 2.) change happens but slowly 3.) price for energy rises, people react, example: in 2008 when the fuel prices reached 1970s - oil crisis levels the US-Americans(many) started to get away from their gasguzzling machines 4.) however: when the prices decrease because of the economic down turn, the gasguzzlers were back in business 5.) it's the price not laws
But perhaps you will mention that I don't take thermal solar not into account 1.) concentrated ? a.) direct to steam - working models exist, yes - working models have problems, yes - heat resistant materials - efficiency is not so good because of secondary processes applied, also the size of the steam turbine is governed by the space up in the chamber tower
here the topics - b. c. d. e. f. g. - also apply see down below
b.) melting salt/natrium to steam - efficiency loss due to secondary process - but nighttime storage for energy - working models exist (small scale plants)
2.) small scale ? - efficiency loss per area due to small delta_T or apply secondary processes (heat pump but also a heat pump needs energy) but great for warming your home pool or shower water - proven technology
Conclusion on why thermal solar power is irrelevant in the picture: At the moment (direct) thermal solar energy makes up only a 1/1000001 small fraction of electrical energy generation thermal energy preservation & storage is however limited by storage capacitiy and the local holding points.
This is because the plants are either small scale working models or plant size working models, but they do come with high investment cost, huge usage of space and "engineering problems" and problems equal to cost for operation and troubleshooting
you need to take the following things into account:
a.) storage of energy - yes you can store pv energy as H2 / but any given process comes with a loss - yes you can store wind energy as H2 / but any given process comes with a loss - energy storage is very expensive
but you should not apply an efficiency factor before the energy is put out into the grid lines. calculate cost for building a storage device
b.) position - you have countries that are more nother and get less direct sunlight - you have countries that are more south and get much direct sunlight
if you want to fill the distance gap goto d.) and evaluate further
c.) daytime & season & weather - bad weather = bad pv, perfect wind - good weather = med pv, good wind - sunny perfect weather = perfect pv, bad wind
- night = 0.4% pv (on a full moon), good - perfect wind - day = good pv, bad - good - perfect wind
season - depends on position
d.) distance - distance is loss the more distance you need to cross the more you loose - if you have distant source and drain your efficiency will decrease
e.) space usage - pv is a space consumer because within a pv field you cannot use much space you will loose much light because it's shadowed away - around wind farms in contrast cows can eat the grass that was fueled by sunlight, the space can be used more diverse
and so: more space equals to less economic efficiency less space equals to more economic efficiency
f.) cost pv is Factor (4 - 8) times more expensive then wind
g.) return of invest / return of energy / resource usage / resource recylcing..
"Just displaced solar energy"
That statement is wrong if used as an argument to support your theory that wind is a niche. Because you leave out the view, that "wind energy" is "conserved" and "transportable" solar energy. If you look at direct solar energy alone you absolutely dissmiss the fact that the earth and it's atmosphere is a storage and distribution network for energy.
The invariant in your view is the pure "scientific" view, yes theoreticly you could replace wind by solar, and vice versa, but on the other hand you would have to find solutions for the topics I mentioned, and finding solutions equals to cost at anytime, the more advanced your solutions are the higher your investment and the operational cost.
Solar power does not work at night - fix it=storage / networkstransfer - costs money Wind power does not work when no wind blows - fix it=storage / networkstransfer - costs huge amounts of money
ok I will lay this out short. this is the pretext you need to understand and asses my view on the topic of renewable energy and on things that sound easy:
1.) I'm a mechanical engineer (with electrical knowledge) 2.) I do work in the wind industry, I do sometimes climb on wind turbines, also Offshore 3.) I know how wind turbine generators work from the inside out 4.) I have a deeper understanding about things like grid codes, grid compliance, reactive power demand & generation, the need for those 5.) I have experience in working safety / I have written safety assessments / done risk assessments / done last minute risk assessments / 5 - stops 6.) But I also know that I'm not perfect and sometimes will make an error, and that there is no perfect or ideal world
Do believe me when I state this from my experience with safety:
- In engineering and science if something reads easy and safe from your office chair view, onsite reallity will change easy to hard and safe to unsafe. - If you ignore that fact, as an engineer having to layout or assign work others execute on complex systems (in dangerous areas) you are a safety problem if you are not aware of your responsility to assess the real situation and not the situation you perceive from your office chair - Do not ignore the human factor
Please guys, be realistic one time, fantasy and dream back and forth.
1.) renuclearization - won't happen on a large scale there won't be a big program to go nulcear, if a country would really do that, they would be ridden with execessive cost (see actual building site in Finland, and take look at England)
Projection: In seven years from now, the project in england will probably cost so much that there will be a pay partly off and walk away solution.
Thinkaboutit: The fixed energy price for that new nuclear power plant in england is higher than the actual subsidies for wind energy, and the reactor will start operating 2025 or so.. when renewables are far more advanced and cheaper. That project won't pay off for the people only for the investors. And in England there is no real threat for nuclear energy through anti nuclear groups, the island is PRO-NUCLEAR (55% are PRO nuclear)
2.) Thorium
Projection: won't happen, too high costs
Thorium will be our saviour. - except that idea is pretty old, it predates the anti nuclear movement, so please cherish the fact that there might be a real world problem with going from drawing board and simulation to reallity, I think thorium reactors are a scientific dream, that when turned into reallity would turn into an engineers nightmare.
Projection: What will happen ? Actually nobody knows.
But we see today that in some countries which have a huge amount of installed wind/solar/biomass power, that on certain times it happens that the renewables generate about 50-90% of the needed electricity. That's good in the first place.
The "bitter" taste is.
The "dormant" coal fired power plants are still running and are paying to sell their electricty, because during several times the stock market price for electricity turns negative. As do nuclear power plants. Because in terms of controlability and medium reaction times power output coal is worse(we talk about hours) and nuclear is impossible (we talk about weeks!)
But what can be seen is a clear shift towards renewables, with - till there is no really cheap, small, availible, high power density method to store electricity - accomodation of the fossils(coal, oil, gas).
Convetional nuclear power due to it's bad controlabilty (not dynamic = bad) and long term nature is doomed to fade out over the next 15 - 25 years.
If you doubt my prognosis about nuclear power, please take a look at the figures of power plant projects (that do not get stalled in the planning phase) Finnland actually builds a new reactor, it was planned 15-20yrs. ago, and the costs have rissen dramaticly, see for yourself at wikipedia. Even b
You make it sound like it's bad to rely on renewable energy, but all your arguments actually strongly support renewable energy:
- short return of invest / return of energy / low investment cost
- technology is state of the art and not something that only ran in a lab or in virtual reality
- you also bring up the best argument in favor of diverse renewables "1/3 transportation runs 99.9% on hydrocarbons", good when photovoltaic and wind are used for generating electricity, the methane can power your truck.
But there is really not enough biomass without getting into food conflicts, but you can also power transportation with electricity and that works. (there are electrical powered busses, they are mostly connected to power lines and not on batteries (capacity problem solved) and the line grabbing and releasing is automatized. Think of a highway with a lane soley for trucks getting there power from grid lines. Yes infracstructure would have to be built, but even in the case you go all nuclear, you would need to find a fix for that same problem.
Ohh now I get it. You think the hippies won and are a foul loser now.. ok, from this perspective: We are really stuck with renewables!
You should actually read all what's written in the text you are commenting on.
Also the 0.5% is an ideal figure in reality the 0.5% would be distributed as your predecessor did also mention.
and btw. which infrastructure well the same infrastructure already present and supplying your computer with electrons, the concept he hinted is decentralized energy generation. And for the computer nerds the redundancy would be Raid1 on steroids.
No not really, ask yourself one question, do you own anything that says "Made in Greece" or anything that says "Made in Japan".
Nobody wants to give greece money anymore. This has some causes, but all accumulate into one big cause, greece does not produce much and has an overblown military complex. They wanted to "fragg" the turks in the past but then they stepped down and collected & displayed tanks as their sign of strength. (try some digging, calculate the "tanks per people" ratio, and compare that to other countries)
And well my home country (germany) - in the past - was willing to lend them the money they needed to buy weapons and also supplied the weapons.

This is the CO2 return of invest of a windturbine. Solar panel is around 10 - 15 Months or so.

I think he will say: Integrating dynamic resource like the renewables with base load - notstopable nuclear power plants - results in a facility near the nuclear power plants where 10000 people start 1000000 2000Watt water heaters simultainously to evaporate the excess power nobody really needs.

Also why I think civilisation will not collapse
1.) 7 billion people and 5 billion living between the middleages and the early 19th century

3.) price for energy rises, people react, example: in 2008 when the fuel prices reached 1970s - oil crisis levels the US-Americans(many) started to get away from their gasguzzling machines
4.) however: when the prices decrease because of the economic down turn, the gasguzzlers were back in business
5.) it's the price not laws
So rest assured civilisation will work.
But perhaps you will mention that I don't take thermal solar not into account
1.) concentrated ?
a.) direct to steam
- working models exist, yes
- working models have problems, yes - heat resistant materials
- efficiency is not so good because of secondary processes applied, also the size of the steam turbine is governed by the space up in the chamber tower
here the topics - b. c. d. e. f. g. - also apply see down below
b.) melting salt/natrium to steam
- efficiency loss due to secondary process
- but nighttime storage for energy
- working models exist (small scale plants)
2.) small scale ?
- efficiency loss per area due to small delta_T or apply secondary processes (heat pump but also a heat pump needs energy)
but great for warming your home pool or shower water
- proven technology
Conclusion on why thermal solar power is irrelevant in the picture:
At the moment (direct) thermal solar energy makes up only a 1/1000001 small fraction of electrical energy generation

calculate cost for building a storage device
b.) position
- you have countries that are more nother and get less direct sunlight
- you have countries that are more south and get much direct sunlight
if you want to fill the distance gap goto d.) and evaluate further

you absolutely dissmiss the fact that the earth and it's atmosphere is a storage and distribution network for energy.
The invariant in your view is the pure "scientific" view, yes theoreticly you could replace wind by solar, and vice versa, but on the other hand you would have to find solutions for the topics I mentioned, and finding solutions equals to cost at anytime, the more advanced your solutions are the higher your investment and the operational cost.
Solar power does not work at night - fix it=storage / networkstransfer - costs money
Wind power does not work when no wind blows - fix it=storage / networkstransfer - costs huge amounts of money
ok I will lay this out short. this is the pretext you need to understand and asses my view on the topic of renewable energy and on things that sound easy:
1.) I'm a mechanical engineer (with electrical knowledge)
2.) I do work in the wind industry, I do sometimes climb on wind turbines, also Offshore
3.) I know how wind turbine generators work from the inside out
4.) I have a deeper understanding about things like grid codes, grid compliance, reactive power demand & generation, the need for those
5.) I have experience in working safety / I have written safety assessments / done risk assessments / done last minute risk assessments / 5 - stops
6.) But I also know that I'm not perfect and sometimes will make an error, and that there is no perfect or ideal world
Do believe me when I state this from my experience with safety:
- In engineering and science if something reads easy and safe from your office chair view, onsite reallity will change easy to hard and safe to unsafe.
- If you ignore that fact, as an engineer having to layout or assign work others execute on complex systems (in dangerous areas) you are a safety problem if you are not aware of your responsility to assess the real situation and not the situation you perceive from your office chair
- Do not ignore the human factor
Please guys, be realistic one time, fantasy and dream back and forth.
1.) renuclearization - won't happen on a large scale
there won't be a big program to go nulcear, if a country would really do that, they would be ridden with execessive cost (see actual building site in Finland, and take look at England)
Projection:
In seven years from now, the project in england will probably cost so much that there will be a pay partly off and walk away solution.
Thinkaboutit: .. when renewables are far more advanced and cheaper. That project won't pay off for the people only for the investors. And in England there is no real threat for nuclear energy through anti nuclear groups, the island is PRO-NUCLEAR (55% are PRO nuclear)
The fixed energy price for that new nuclear power plant in england is higher than the actual subsidies for wind energy, and the reactor will start operating 2025 or so
2.) Thorium
Projection: won't happen, too high costs
Thorium will be our saviour. - except that idea is pretty old, it predates the anti nuclear movement, so please cherish the fact that there might be a real world problem with going from drawing board and simulation to reallity, I think thorium reactors are a scientific dream, that when turned into reallity would turn into an engineers nightmare.
Projection:
What will happen ? Actually nobody knows.
But we see today that in some countries which have a huge amount of installed wind/solar/biomass power, that on certain times it happens that the
renewables generate about 50-90% of the needed electricity. That's good in the first place.
The "bitter" taste is.
The "dormant" coal fired power plants are still running and are paying to sell their electricty, because during several times the stock market price for electricity turns negative. As do nuclear power plants. Because in terms of controlability and medium reaction times power output coal is worse(we talk about hours) and nuclear is impossible (we talk about weeks!)
But what can be seen is a clear shift towards renewables, with - till there is no really cheap, small, availible, high power density method to store electricity - accomodation of the fossils(coal, oil, gas).
Convetional nuclear power due to it's bad controlabilty (not dynamic = bad) and long term nature is doomed to fade out over the next 15 - 25 years.
If you doubt my prognosis about nuclear power, please take a look at the figures of power plant projects (that do not get stalled in the planning phase)
Finnland actually builds a new reactor, it was planned 15-20yrs. ago, and the costs have rissen dramaticly, see for yourself at wikipedia. Even b
You make it sound like it's bad to rely on renewable energy, but all your arguments actually strongly support renewable energy:
- short return of invest / return of energy / low investment cost
- technology is state of the art and not something that only ran in a lab or in virtual reality
- you also bring up the best argument in favor of diverse renewables "1/3 transportation runs 99.9% on hydrocarbons", good when photovoltaic and wind are used for generating electricity, the methane can power your truck.
But there is really not enough biomass without getting into food conflicts, but you can also power transportation with electricity and that works. (there are electrical
powered busses, they are mostly connected to power lines and not on batteries (capacity problem solved) and the line grabbing and releasing is automatized.
Think of a highway with a lane soley for trucks getting there power from grid lines. Yes infracstructure would have to be built, but even in the case you go all nuclear, you would need to find a fix for that same problem.
Ohh now I get it. You think the hippies won and are a foul loser now.. ok, from this perspective: We are really stuck with renewables!
also these wind turbines do actually in most countries supply the biggest part of the renewable energy mix.
Install it by yourself go off grid and call yourself tea party anti-government!
Now better ?
You should actually read all what's written in the text you are commenting on.
Also the 0.5% is an ideal figure in reality the 0.5% would be distributed as your predecessor did also mention.
and btw. which infrastructure well the same infrastructure already present and supplying your computer with electrons, the concept he hinted is decentralized
energy generation. And for the computer nerds the redundancy would be Raid1 on steroids.
No not really, ask yourself one question, do you own anything that says "Made in Greece" or anything that says "Made in Japan".
Nobody wants to give greece money anymore. This has some causes, but all accumulate into one big cause, greece does not produce much and has an overblown
military complex. They wanted to "fragg" the turks in the past but then they stepped down and collected & displayed tanks as their sign of strength.
(try some digging, calculate the "tanks per people" ratio, and compare that to other countries)
And well my home country (germany) - in the past - was willing to lend them the money they needed to buy weapons and also supplied the weapons.
If you recognize the debt-collector-junkie-drugstarter relationship ?
