  1. In this house we obey the laws of thermodyanamics. on Researchers Improve Solar Cell Performance · · Score: 1

    So let me see, current cells have 15% efficiency or so , the best stuff ( I.e GaAs ) can reach 30% - 40% , and this tech will increase output power by more than an order of magnitude, meaning they should output at least 150% of the energy they receive?

    If the numbers are to add up then what they are doing is a concentrating solar power plant and it should be compared to the values for such instalations. Heck, using their way to do the counting I could design a power plant which outputs 100 times the power of existing state of the art solar cells, by using a 100m array of mirrors and a stirling engine. In fact, this has been done.

    For proper comparison they should compare their technology with other concentrating solar technologies, in which case I'm suspecting they get their ass kicked by solar thermal installations that have superior conversion efficiencies.

    You jest , but your coment should actually be moderated insightful. While radioactive the chemical effects from uranium and lead alike outdo the radioactive ones from uranium by orders of magnitude. In terms of toxicity lead is probably a lot worse than uranium. The concern with DU as used by military is mostly when it is used in armor piercing rounds, where the bullets are propelled to sufficient velocities to powderise them on impact. The concerns is that finely powderised uranium may get stuck in people's lungs, greatly increasing exposure. While there are varying opinions about the extent to which this is a problem, the concern is almost completely down to the uranium powderising. Had regular lead been used in a similar way ( it is not because it is far too soft for an armor piercing material ) the effects would likely have been worse than with uranium, since lead is significantly more toxic.

Zimbabwe is the same. The only difference is what excuse these regimes use to justify their crimes. In soviet it was political ideology. In Iran it is religion. In Zimbabwe it is skin colour. What they have in common is that they kill and torture people in order to make the public afraid of organising opposition, their official reasons (religion,economics,race,culture) for doing so have little to do with their actual objectives.

    Not quite. It was found that for certain types of goods and services ( healthcare, education, defense etc... )it worked rather well. In fact, it works so well that even the USA is considering to finance healthcare through a centrally planned system rather than the free market. They don't say it too loudly, and obscure what it really is by calling it other things, but that is essentially what is being done.

    The flaw of comunism was not that it recognised that SOME goods and services were better provided throughc entral planning, the flaw was that it assumed that the best way to provide one type of good would necessarily be the best way for ALL goods. In reality central planning works well when goods have large positive externalities, and especially so for public goods. Conversely a free market works well for goods that have no, or minor , externalities, and fails horribly in other cases ( pollution, health care, etc.. ).

    The flaw of capitalism is the same as the flaw of communism. It is based on an assumption that all goods and services are equivalent. In reality the extent to which suplier and consumer in a private market pay and benefit from all the effects of a good ( positive as well as negative ) depend greatly upon how much third parties are affected by the goods production and use. For some goods the costs and benefits are accounted for almost completely by the market , for these goods capitalism works well. For other goods there are large external costs and benefits that the market doesn't care about. For these goods capitalism fails horribly.

    Meh, once you study some philosophy you can screw up the notion of ranking diciplines rather easily. Observe:

    On the other hand, the laws of physics are not fully understood, and you could very well argue that the present understanding is merely a consequence of our tendency to make extrapolations of observed trends. Hence our tendency to believe there is a fundamental set of physical laws is a matter of psychology. Physics is merely applied psychology.

    Of coruse, psychology only makes sense if you assume there are other conscious beings in the world, and this is a belief that cannot be tested experimentally. One could therefore question if assuming that there is a real world is any less irrational than assuming there is a god, and depending on how you answer that question you may well argue that all knowledge is merely religious beliefs that we adhere to with various levels of conviction.

  10. Re:Because on Children Concerned By Parents' Web Habits · · Score: 5, Insightful

    Bullshit, there are essentially 3 ways in which drugs cause addiction.

    1: First of all many drugs are indeed very pleasant. In fact, some of them, like cocaine, cause such extreme releases of serotonin and dopamine that this effect will on its own make virtually everybody who use it addicted to it relatively quickly. We are hardwired to get somewhat addicted to things that are pleasant (like sex), the problem is that some drugs have so strong effects that this effect goes beyond everything else. It is not about having an addictive personality, because everybody have a tendency to feel some form of desire or need of things pleasant, and drugs like cocaine strikes strongly at this by preventing the reabsorption of signal substances in the brain, resulting in a massive spike in the levels of the hormones that make us feel well.

    2:Many drugs cause pain when you try to stop using them. Nicotine and Alcohol are probably the most well known examples, but Heroin has similar effects. Because the body tries to adjust to the effects of the drug, ceasing to use it can mess you up fairly bad. Smokers tend to get a bad stomach when they stop, alcoholics experience headaches, and heroin abuses can literarely go mad trying to stop using the drug. There are a lot of further symptomes but what they have in common is that ceasing to use the drug creates unpleasant symptomes. These effects have been clearly demonstrated and are not merely psychological. Many drugs affect more parts of the body than just the brain and some of these side effects show up when you quit.

    3:Some drugs prevent you from feeling pleasant from other things without the drug. Long time smokers can find it difficult to relax without nicotine as an example. As the body creates extra receptors to compensate for the effect of the drug, more of it is required to trigger the same response ( being one reason why smokers tend to smoke more and more the longer they have been addicted ) and other things that would normally make you feel pleasant may have a dimnished effect unless the drug is pressent simultaneously.

    It is true that a number of authorities have inconsistent policies, but mostly this takes the form of having less stringent rules for nicotine and alcohol than for drugs like cannabis. It doesn't mean cocaine or heroin are harmless, and indeed the problem with people not trusting the authorities when it comes to advice on these drugs is one of the reasons why pretending that cannabis is way worse than alcohol or nicotine is retarded. By undermining their creidbility by greatly exagerating the dangers of cannabis, the authorities are causing a lot of people to underestimate the dangers of drugs like heroin. This is a major problem since the latter, unlike cannabis, will almost certainly destroy a person, and a heroin addiction makes nicotine look like a slight temptation in comparison.

  11. Re:Pollution on The World's 10 Dirtiest Cities · · Score: 4, Insightful

    It works like this:

    The main reason Coal is being used to produce electricity rather than say Nuclear, Wind Power and Solar is price. Coal is cheap. If you impose a carbon tax , however, forcing companies that emit a lot of CO2 to pay for it, then that will make electricity generation from coal more expensive, and thus hopefully cause electric utility companies to build nuclear power plants, wind turbines, and solar panels, instead.

    The idea is that you integrate the environmental cost of pollution into the market system, thus forcing supliers to take environmental concerns into consideration when making business decisions. Now, while flat out taxation is one way to achieve this, it is very difficult to determine how much to charge for a given amount fo environmental damage, and this is where tradeable emission permits comes into play. Rather than taxing companies directly, what you do is you decide how much of a certain pollutant we can emit without causing major trouble, and then you auction it off to highest bidder. That way you force the market to adapt to a lower emission scenario, and the price adjusts itself according to normal market principles. With time you can then reduce the "acceptable" level of emissions as technology improves, periodically reducing the amount of pollution.

    The catch is of course that this WILL have negative effects on other aspects of the economy. The important thing to realize is that this is not some new negative effect the government has created, it is a price that we were previously paying in terms of environmental damage. What tradeable permits do is to limit the extent to which manufacturers can impose that cost on everybody, and instead put it right down where it belongs , with the consumers that use goods and services that generate pollution during their production. Yes, I said consumers, not companies. Manufacturers will on pass the cost to the consumers, in the form of higher prices, and this will in turn reduce demand.

    "Oh but you can tax as much as you want people still want to drive their cars... blah blah blah...". This is why you use tradeable permits rather than direct taxation. Tradeable permits outright forces the market to adapt meaning prices will increasethe UNTIL they are high enough that demand drops. When it comes to goods that people consume a lot regardless of price ( such as gasoline ) this trabnslates into a large price increase. When it comes to things you can eaisly replace with other things, the increase in price will be smaller.

    The real problem is that the cost of CO2 is really really large. Emitting it causes major damage to the planet, curtailing it causes huge costs to the environment. There isn't an easy solution to this, which is why a number of peopel prefer sticking their head in the sand and deny the whole thing. I am seriously very sceptical to weather the necessary measures will be taken. People won't put up with a 3 fold increase in energy prices ( which is where wind power is relative to coal and nuclear ) so if we hope to get rid of coal it would appear that unless we get a sudden breakthrough in solar, only Nuclear has a chance to save us. Somewhat ironically, the most hardline environmentalist groups oppose it almost religiously, and thus it woudl appear we will be stuck with coal for a long time.

    As much as I am against the wiretapping, it isn't actually wrong to make the telcos immune to something the government required them to do. The problem is that you can't realistically punish those in government who were responsible, but that isn't a reason to go after the telcos. Does anybody actually think they had much choice in the matter? You are talking about a government which has empowered itself with the ability to request sensitive information from people and then order them to stfu about it under the threat of persecution. The telcos may be bastards, but holding them responsible for something the Government most likely strong armed them into doing makes no more sense than denying somebody his right to a fair trial "because he deserves it".

    In this particular case the blame rests with the government, the problem is that they are already untouchable, which is why people are going after the telcos. Somebody ought to pay, and because it isn't possible to make the ones ultimately responsible pay, people have picked the telcos as the scapegoat. Problem is "they are bastards and deserve it" isn't a good reason to sue the wrong institution.

Yes, it can be used to attack whistle blowers and political dissidents, but it may also help prevent people intimidating political opponents through the use of violence and threats.

    The real question when it comes to laws like this is not as much "what will this system be able to do" but rather "how do you ensure this system will not be abused". With technological advances I really do think it is somewhat inevitable for these things to become commonplace, it can be delayed at best. Therefore what we should really be campaigning for is not an end to wiretaps, CCTV cameras etc... but for checks and balances that prevent the techs from being used for nefarious purposes. If we could indeed know that these systems would only be used to deal with threats from terrorism, solve murder cases and robberies, etc... then I doubt many people would oppose it.

My point was simply that if you are going to expect customers to grin and bear it without complaining, then companies should expect the same treatment from the government. As any sane person would be able to rapidly deduce, this is not really a practical way to do things, and thus the "if you don't like it don't use it" argument is nonsense. There is no reason why customers should "just not use it" if they are unhappy with a product, the same way there is no reason why a company should "just not do business there" if they dislike the local laws.

    Furthermore because the communications infrastructure is partially government funded, and as the radio frequencies are government controlled through the FCC , the "free market" argument doesn't hold water. There are numerous barriers to entry into the ISP market, both government imposed as well as technical ones, and thus coercive monopolies will be able to form unless actively restrained by the government.

    This doesn't necessarily say much about HOW you should regulate the market, but it pretty much implies that simply leaving ISPs to screw over customers and smaller competitors is a big no-no. Completely free unregulated markets only work when there are low barriers to entry, many suppliers, no external costs or benefits, perfect customer insight into the market, completely homogeneous and equivalent services being offered, zero cost of switching supplier, and no barriers to trade.

    It doesn't (there are other points where GR and QM conflict, but entanglement is not one of them ). Einstein thought it did because he assumed that any such interaction would be deterministic and could hence be used for communication (THAT would break GR ). Essentially Einstein never liked the idea that the universe was based on randomness, hence the famous "god does not throw dice with the universe" quote. As a consequence he repeatedly tried to disprove quantum mechanics by inventing scenarios in which the random nature of QM would conflict with GR. The surprising, and somewhat ironic, outcome of his attempts was however new insights into quantum mechanical interactions that just seem to confirm the random nature of QM.

    Also, to be pedantic about it, entanglement doesn't in principle imply that an interaction is quicker than the speed of light. You could alternatively claim that the interaction occurs with the speed of light, but the ENTIRE UNIVERSE ends up in an indeterminate state similar to that of Schrödinger's cat until you receive Alice's message. Thus you can keep interactions restricted to the speed of light ( locality ) but in order to do so you would have to throw out the notion that Alice exist when you do not hear from her ( realism ).

    In practice throwing away realism would force you into a rather solipsist interpretation of reality which I think even Kant would have issues trying to accept, and thus most of the time we just stick with the much more comfortable notion of having a reality with instantaneous long distance interactions. If nothing else this is a lot easier to visualize than imagining the entire world entering a superposition of states until you receive Alice's message.
