    So how much more expensive is the second, "smoothing" phase than the original production phase? And how much more expensive is the later "interfacing" stage, where hydrophobic/philic lipid layers encase the dot in something like a hemi cell membrane for interfacing with biological spaces? Including the cost of a skilled operator, like the one in this video who seems priceless in marketing the process to nerds ;).

    And how much do the products of each of those phases currently cost, per (kilo)dot? In other words, what is the cost per dot in each phase, compared to the price per dot in each phase? Silicon chips are expensive to make - compared to, say, steel - but per saleable unit they're cheap. At least in the earliest, least packaged phases of the industrial supply chain.

    It seems to me that characterizing the dots requires only a calibrated source of UV (cheap) and a calibrated spectrometer (pretty cheap). At least in characterizing their phosphorescence, which is the characteristic that seems of main importance to this cancer lab, and to most optical switching applications.

    Maybe too expensive for most Slashdotters, but not too expensive for even a paint factory. Or an inkjet ink factory.

  4. What's So Expensive? on An Easy Recipe For Quantum Dots · · Score: 2

    That video showed a lot of mixing, boiling, separation. None of it looked very expensive. The presenter mentioned a second process that smooths the surface of the initial yield of dots which might be expensive. But that just makes the dots more efficient at processing light. If the initial process is really cheap, the lower quality might be a better value than continuing the second process for an improvement relatively small compared to its increased cost.

    While we work in labs to cheapen the refinement process, we could get a lot of cheap dots to apply to other uses that will only improve when the refinement process becomes cheap enough. Getting the dots into industry will ramp up demand for the higher quality ones.

    As a side effect, places like China that tolerate toxic products as we see being contained in that video could dominate the market for the initial products. But places like the US that are less tolerant of toxins in the workplace and in pollution, but are more geared towards specializing in higher quality products (refined in different ways for different properties), could refine the raw dots into more valuable and effective products. Leaving the US dependent on China for raw materials, but able to switch suppliers to some other place, like India, that is similarly tolerant - or make the raw dots ourselves if a crisis outweighed the protections from toxins we used in the course of normal business. All of which could make a proper market, with balanced protections, that gives the world lots of cheap, and sufficient amounts of quality, quantum dots. Whose efficiencies and effectiveness can eliminate toxins and pollutions these dots replace in the industries where they're adopted.

    I've worked with, for and among political offices. It's very well known in that biz that a written letter is much more effective than email, unless you're already an associate of the recipient.

    Snail mail is always best for corresponding with politicians and officials with whom you don't already correspond regularly. They're more likely to have it handed to them, because they're mostly old and think email is for people who think for a living, not schmooze. And even if it's just a staffer who reads it (and maybe mentions it to the politico - or better yet, gets it to influence the work their office actually does among other staffers), a letter is better. Lawyers and other official correspondents use snail mail, sometimes as required by law or contract. And the people who write letters tend to be people who vote. Both because they tend to be older, and more office-oriented, and to be people who put actual time into the political process.

It won't be some exotic, perhaps damnable mystery. Getting everyone exposed to programming would humanize those of us who turn out to do it a lot.

    I don't think it'll help much in protecting nerds from getting stuffed into lockers by jocks. But maybe later when that jock is the useless midlevel manager telling a programmer how the thing works the programmer is automating, or when the jock is thinking about asking a programmer for something, they'll have some recollection about doing it themself a little way back when, and so relate better to the "whiz", and maybe deal with them better.

There's no simple relationship between what a worker was doing and what the corporate rulers say the corporation will now do, when the corporation fires so many people at once. Especially when the corporation was profitable and known for quality before the firings.

Like all the corporate execs and their ecosystem who are responsible for pure finance, including managing the company's publicly traded equity (stock) and publicly/privately juggled debt (bonds, mortgages, government loans, private loans, credit default swaps, other derivatives).

    It costs so much to drill here primarily because labor and environment are more protected than in foreign deserts, jungles and seafloors. When drillers cut costs, we get BP's Macondo blowout. Secondarily because the easiest oil to reach has already been pumped out of here. The places where it's cheaper to drill have by far the more controlling, corrupt and wasteful governments.

    The people and orgs that employ IT workers aren't failing to hire because the government taxes them and gives the money to others, either for them to do IT or for any other purpose. Indeed, I don't know what you're referring to about a lack of IT job options in 2006. Or how a NASA job is a "decidedly not government contract". The IT industry has had a synthetic brain drain into finance for the past 10-15 years, because deregulation made stealing money through fraud and market manipulation more profitable than anything else. I know: I helped automate the insurance industry (bringing OOP to MONY and The Guardian to the Internet) in the late 1990s, when "integrated financial services" eliminated the 1934 regulations preventing "another Great Depression" so they could sell Credit Default Swaps and other derivatives - that created the Great Depression. I also worked in 2009-2010 programming for some of the 10 biggest hedge funds, cleaning up their trading apps and DBs as they moved from the Bubble risk models to the new scams designed around the bailouts and more diversified robbery targets. My job was to delete the old stuff without breaking their $BILLION-daily businesses, not create the new criminal businesses replacing it, so my conscience is pretty clear. But I moved into energy management (and a pay cut) because I prefer to help solve the problem rather than help create it. During Bush/Cheney, 40% of the US GDP growth was in purely finance property: mostly a fraud, as the equities market it underwrote lost an eerily similar 40% of its value when they ran out of suckers and the vultures came home to roost with the ARMs finally rising to high contracted interest rates. There's only so many trillions around to work, and working them in finance that mostly adds no value (but does largely destroy value) did divert investment that in the 1990s built actual wealth by creating telecom systems people actually used to do real things beyond pure property trades.

    I also don't know how you're comparing Houston's tolls to the Federal projects that built them (with the nation's taxes). Sure, when you've got bottlenecked road systems, it's trivial to make money tolling them, especially when you've conned the users into paying high starting tolls on promises of ending them promptly. But the Federal government's original construction of them, without tolls, wasn't planned to turn a profit, nor should it. The national public good of Houston's vehicles moving around for business and personal transit, and the military propaganda required in the 1950s to get Americans to invest in infrastructure, was worth the expense without direct use fees that didn't reflect the widespread national benefit. That Houston has taken to exploiting the infrastructure and its users for profit can't be compared to the Federal construction and operations that didn't work that way.

    I'm reminded of Texas governor and presidential nomination candidate Rick Perry's claims to Texan job creation. Which turn out to be government jobs paid by Federal programs funded by national taxes. All while Perry rails against the Big Government that provided it, even threatening to secede from the nation when his cronies aren't in power (and while insisting he loves that nation from which he wants to secede). I understand that's the Texan way, now a permanent feature after Perry and Bush (and really forever, including Democratic governors/senators, including those who became president). But it still doesn't add up. Unless you're a crony. And I'm not.

Those corporations have been calling the shots since Henry Ford, and are the ones who tore up America's rail to replace with roads and cars. Those are the orgs that set up Houston, Oil City, the way you hate - not the unions.

    You can tell me about how your family oil business knows there's so much oil left to drill, yet despite getting royalty-free drilling land practically wherever they ask, their industry doesn't drill. Except maybe when getting Federal money from the rest of us to multiply their profits. The actual unlimited supply is self-serving lies about where oil is or isn't coming from oil companies with agendas to maximize profit by increasing demand and decreasing supply.

    I can tell you from direct experience that NYC building owners don't invest in their operating capital even when the ROI is, as I told you, close to 100% or better, except when the government both forces them and pays them to do it. It doesn't make sense. But that's because economics is not like electronics, where consistency and actual value rule the actors. Economics is a measure of people's exchanges of value with each other and their environment. Which means it's governed by human social psychology, not primarily by the potential and limits of the material being exchanged. Despite their deserved reputation of being the worlds most determined capitalists, NYC building owners refuse to make rational investment decisions all the time. It's not because of property/zoning laws/regulations. It's because they are used to increasing profits only by cutting immediate costs (like cheaper maintenance workers) or by reducing the supply of real estate against the constantly increasing demand for it. Purely rational people would change despite what they're used to when there's double or triple digit ROIs from investing in necessary costs they have to pay anyway (boiler upgrades and fuel). Building owners don't change, because they wait for everyone around them to change, or to be forced to change, or to be paid to change - or all of them usually.

    Again, this is not some kind of guess at what might happen. Also, your statement that the rich in NYC are taxed so much that they flee to other states is just a lie. Except for the extremely rich who move across the state line to Connecticut. It's not that they're taxed so much in NYC, but that they're taxed so little in CT. So when rivers overflow in predictable storms, they're surrounded by a moat their private airlifts have to get across with food and diesel for their generators. Because without taxes and working government their infrastructure, like roads, powerlines and drainage, can't withstand the changes their businesses are making. They are the tiny minority. NYC is full of the richest people in the world, not despite the taxation but because of the services it pays for. And every day more rich people come here, to pay the taxes and consume the services.

    FYI, NASA is not a good example to contest government leading energy efficiency, because building efficiency is not rocket science. NASA as run by either a Republican president or Congress or both for the past couple of generations is like any other large government procurement system: corporate welfare for those who sell by the part# through their DC lobbyists.

For over a century before that the US military was among the top 5, though probably actually still the most powerful since about the 1860s, but confined to North America. During that time the US has invaded only its neighbors to the west (native nations) and south (Spanish Mexico, and then Mexican Mexico), and not for a century now, and very occasionally small distant countries with either no substantial military (Grenada), or similarly sized military (Iraq, Nazi Germany), or substantial counter-insurgency communities (Vietnam, Afghanistan).

Instead we invaded Iraq, sending oil to $100:bbl for most of a decade, while promoting SUVs and even Hummers that get 1/3 the mileage we should require from cars.
