  1. Re:Awesome on Boeing 787 Makes US Debut · · Score: 4, Interesting

    In this country, executives get paid for performance-- or at least for tweaking the stock price. Unions, with their incessant demands for decent working conditions, interfere with the creation of totemic representations of shareholder value.

    That was a joke right? "Shareholder value" when talking about passenger airlines is pretty much zero. The lifetime profit/loss of the industry is a loss. Every legacy US airline has declared bankruptcy at least once. Southwest has not gone belly up, but you would have been far better investing in the S&P 500 over the last five or ten year periods, perhaps longer.

        The problem is that owning airlines is "sexy" and way too much money is invested in it. The result is that shareholders are completely and utterly screwed. The problem with airlines is not the execs, the unions, the corporate structure, or even fuel costs. The problem is the "sexy" factor has caused there to be way too much capacity built and no airline can operate at a long term profit because of it.

    funny, I go with the lowest bidder for airlines based in other parts of the world and the food, beer & wine, entertainment and courteous service are included. the US airlines *could* do it if money-grubbing scum weren't allowed to get away with excessivly lining their own pockets

    Right now, the aviation industry has a net loss for the lifetime of the industry. The stockholders certainly don't see any money, and they keep getting totally wiped out. Compare executive compensation of airline companies and other companies. Airline execs make far less on average than execs at companies of similar sizes. Who is left? Who are the "money-grubbing scum"?

    You wrote " There are quite a number of people out there that would sooner die then choose Apple because of their shiny retarded walled garden approach to computing. I'll go back to a clamshell phone before I choose Apple for anything."

        I respect that choice. I personally want that walled garden. Decades ago, before malware came around, I used to spend 5K a year on software. Anything that I thought had a chance of increasing my productivity, I bought it. Malware changed all that. I now have to consider the risk that some cool little utility will utterly screw up my system. Or install stupid tool bars that I have to spend way too much time to get rid of. The result of this is the amount of software I consume has declined by 75% compared to 25 years ago.

        The Apple walled garden changed all that. I can install boatloads of things with a very high degree on confidence that they are safe.

        My brother in law has a PC that got infected with hundreds of pieces of malware and is unusable. His Iphone and Ipad are going along just fine.

        There are a large number of us that very much want a walled garden. Yes, it is not for everyone, but it most certainly is for some of us.

    > I understand that the grad students of a few Nobel Prize winners have been pretty embittered by the lack of official recognition of their contributions.

        Having worked with just such an embittered professor, I would go as far as saying as some Nobel prizes should have been awarded to the grad students.

        I also think there is a bit of a presumption in the Nobel committee to assume work was done by the older and wiser professor. When Bardeen came up with the theory of super-conducting, a key (if not THE key) element of the theory is the concept of Cooper pairs. Cooper was a grad student working with Bardeen. How much you want to bet that Cooper came up with the idea, and Bardeen named them Cooper pairs because Bardeen wanted to make sure Cooper shared in the credit for the theory? If there were more professors like Bardeen, there would not be quite so many embittered former grad students walking around today.

        Fun fact: Sheldon Cooper of Big Bang Theory is actually named after the Cooper who helped formulate the theory of super-conducting.

    Almost everything I buy in the continental US is shipped/flown in, as well, from sardines to salmon, mandarins to garlic, as well as small appliances and almost everything electronic (including wire), and of course cars.

    Even if that is true in your case (and is most certainly is not true for most Americans), there are a host of things you indirectly consume that are surely made in the 48 states.

        Your electricity comes mostly from coal and natural gas that all came from within the country. That car you said was shipped in? Well, you may own an import, but most Americans do not. And even imported cars might have been made here. Toyota, and many others, have plants in the USA. You ever eat bread? The grain was grown and processed in the US. How about soap? Yeah, that was made here as well.

        How about your house, did you import that? If you live in Hawaii, you actually will be importing most of the building materials. Are the roads you drive on imported from Germany? Nope, the asphalt comes from refineries in the US. How about the steel and concrete for that bridge you just drove over? Yep, that all came from with the 48 states as well.

        By weight, you would be shocked how much of what you use in your life actually came from within the 48 states. It is probably in the ballpark of 95-99%. In Hawaii, almost all of that has to be shipped in. And in relatively small quantities as well, which just compounds the pain.

    Oh come now. You repeated essentially exactly the same statement as GP and then claimed GP was wrong?!?!

    If the OP's statement was true, most panels would need to be replaced by the 25 year mark, since the standard panel guarantee is a minimum of 80% at the 25 year mark. Very few panels are replaced as most do much much better.

    And it's not a "guarantee". Nobody guarantees anything for 25 years.

    Solar panel makers do exactly that. see http://us.sunpowercorp.com/support/warranty/

    Solar panels are warrantied for maybe 1-3 years against manufacturing defects if you're lucky, and that's about it.

    True.

    * if you have kids, odds are good they're going to throw something onto the roof. Odds are better that it'll be hard enough to crack the glass on a panel.

    Not true. Panels are designed to withstand pretty heavy hail hitting it at terminal velocity. Unless your kids are shooting at your roof with a gun, the panels should be fine.

    * even top-end panels last about 25 years max before peak output drops below 80% of rated Wp

    Not true. Standard guarantee is that panels will be at the 80% mark or higher at 25 years.

    Finally, to make a panel, you have to burn an unholy amount of electricity just to feed the CZ furnaces for the wafers/cells (letting alone wafering, cell processing, panel construction, etc). It has to come from *somewhere*...

    True. But energy payback time is down to between .5 and 1.4 years depending on exact technology used. That's from the EPIA March 2011 white paper, and things are surely better now.

    Man how many times have we seen these stories already - "cheap solar power discovery, will make solar pv affordable" but then years later nothing has changed.

    It would be great if some of these things actually got productizd, I would set up solar pv all over my property if it was just a bit more cost effective...

    Nothing changes???? In 1980, solar PV cost about $22 a watt. If you order a large system today, you can do that for about $3 a watt. If you take inflation into account, that 1980 number is closer to $50 a watt in today's dollars. Yes, a reduction in price of 94% is peanuts compared to what has happened with computers, but that still beats the heck out of all of all the other energy sources. For example, oil costs more today than in 1980. Coal costs more than in 1980. And so it goes.

        Solar is already cheaper than grid power in some areas. If prices keep dropping at the same rate they have been dropping (about 8% a year), within a decade, solar PV will be cheaper than the retail electricity rate for pretty much everyone in the US.
