    "Wow I guess you really have no real grasp.
    Let me put this simply. reliable, faster turnaround, reusable == cheaper."

    Wow, I really do have a grasp. Thanks for restating the obvious.

    "With a horizontal takeoff you must support the weight of the fuel on the landing gear which is a separate weight structure from the thrust bearing structure since one will be taking a horizontal load and one the vertical load."

    I think this is a common problem for all aerodynamic vehicles, isn't it? We've done some good work in that area if I recall.

    "Then add in the lifting surfaces that will be needed to left the weight of the massive fuel load which will then be nothing but dead weight when landing."

    Are you describing the Shuttle again? Is that a good model for future spaceflight? Just asking. ps - 'dead weight' when landing decribes an entire vehicle, if you're pointing out that lifting surfaces are 'dead weight'. Like landing gear. What? So capsules are the most efficient vehicle, right? Are they the most useful? Is there a difference?

    "Then the wing spar needed which will be another massive structure adding even more to the weight."

    I'm guessing spars will be part of the lifting surface structure, but if there is an alternative, cut these.

    "Which will add more to the weight of the landing gear which will mean more fuel which will mean more load on the spar, more wing area, and.....

    Yes, it does. I'm not as daft as you think I am, though I'm not writing the same stuff as you. this sometimes leads people to think someone 'doesn't get it'.

    I'm not so much focused on 'cheap access to space', as in reliable, faster turnaround, reusable. I don't think we can do that with the current model of vertical lift, aka Shuttle/Thor-Delta-Ares-etc, but if a true Shuttle replacement could be launched more horizontally, this might solve the problem of big rockets pushing things straight up (at first). That demands big motors and big fuel burn rates.

    I know, we need materials and propulsion advances. Similar problems in transportation, especially passenger cars, and we are playing with batteries as an interim step towards other energy sources. Not directly applicable to space travel, but similar fundamental problems - changing the paradigm.

    It takes vision and committment. Both lacking in our nation and government.

    Well, I hope not. Ares is a bust, but looking at the commercial projects gives me hope that we can get off the vertical lift scheme and build real space planes. It seems as if there is an economy to a lateral lift that would solve some problems, but not being an engineer means I can't work out the details.

    He's right, you're wrong. Satellites are limited to the capacities of the launch vehicles available, and those vehicles were designed for the bombs. Or the bombs aer designed to the limitations of the vehicles. Same problem for satellites, though they didn't drive vehicle development until fairly recently. Even now, it's as much packaging as rocket that limits satellite design. The USAF seems pretty interested in the X-37 to deliver military satellites, and I wonder how big the

  11. Why not, indeed? on Neal Stephenson On Rockets and Innovation · · Score: 4, Interesting

    Stepheson makes this point late in the article:

    "There is no shortage of proposals for radically innovative space launch schemes that, if they worked, would get us across the valley to other hilltops considerably higher than the one we are standing on now—high enough to bring the cost and risk of space launch down to the point where fundamentally new things could begin happening in outer space. But we are not making any serious effort as a society to cross those valleys. It is not clear why."

    It's somewhat clearer why, to me.

    I want to buy a more fuel-efficient car, and keep my current, less-efficient car. My current car is useful for many things, but commuting to work could be done by another, more efficient one. Here, however, is the rub. Despite the improvement in fuel economy, it is still a net increase in cost to me for a fairly long time. Acquisition, insurance, and upkeep consume most of the fuel savings. Yes, it would be better for he environment also, but that doesn't immediately or directly impact my costs very much. So I put off buying that car.

    Our current methods of delivering object into space work well enough, and the alternatives are both unproven and not sufficiently advantageous to warrant immediate adoption.

    However, as we re-enter manned space exploration, we will be looking for heavy-lift options that don't actually exist today, and those present the opportunity to develop new methods. Avoiding the vertical portion of a rocket launch also avoids the need for massive thrust to overcome gravity that directly. Stephenson alludes to this, and 'space planes' are the current focus, along with some multi-mode concepts. NASA'a failing Ares program is a fair example of lock-in that Stephenson is writing about. Being more open to the development of ultra-high-speed vehicles and their engines might offer both better alternatives and true advances. But that takes ingenuity and a willingness to risk that NASA doesn't seem to possess right now. Bad climate to propose trillion-dollar space programs, though we've been willing to propose trillion-dollar stimulus packages for more mundane projects, such as propping up failed financial institutions.

    Imagine the impact of a trillion-dollar space plane project. Would US students consider a career in engineering if they saw both the opportunity to be part of a cool new future, and the employment options as well? Would this give US aerospace companies something else to sell instead of weapons systems, and is that a good thing? Would it spur international competition, and is that good? Would it divert China's resources into something besides crushing the world's manufacturing competitors? Does that matter? Would a trillion dollars given to this project do more good than giving it to the bankers? Will the bankers also flourish in the glow of this project?

  12. Re:Intel is getting ahead of this one on Asus, Gigabyte To Replace All Sandy Bridge Boards · · Score: 1

    Intel so far has publically stated that this problem wasn't detected in their testing. I kinda believe that, and the root cause makes sense of that. The chip wasn't slipped in after the LAST round of tests, so the assumptions that Intel didn't test this design adequately will probably prove false. I haven't heard any credible report that Intel had any suspicion that this problem existed, or could, before shipment. Changed seppings may not have spotted it, for as you pint out, this needed extreme testing regimes to be revealed. Prototypes can't be relied upon as production examples for obvious reasons.

    This would not be the first time Intel has had to retract a part because of materials problems. Just the first time in 2011.

    And one item caught my attention. Intel seems to think that this would affect at least 25% of these parts over a three-year period, and lead to substantially shorter useful life for nearly all of them. In fact, I think they predicted that the vast majority of parts would show no failures for 1-2 years.

    And another item. Anandtech reported that an Intel spokesman said that the fix was to remask and essentially diable the offending transistor. That doesn't square with what I know. But it is common in these cases for one team to blame another, so it coudl be a design team is being lamed by manufacturing for driving a device to failure, where design might be pointing out that the device wasn't manufactured to spec, and is failing because of that. Often, both teams get a trip to the woodshed, since resolving these problems has to be a team approach, and having teams covering their butts first can lead to delays and costs.

    There are teams within Intel that can do their investigation without interference from the CYA gangs. Fortunately for us.

    Actually, Intel got returns back from their customers (Dell, for one), and as soon as they analyzed the chipsets, they found the materials problem. The 'torture tests' were in response to the defective parts and the failure mode. That 'only' gets them to choosing the next step, is it hardware or firmware? Assuming,of course, that it is a defect, and not something else. My friend in driver development spends a fair amount of his time proving that the error is not his code. Less than a while ago, since he moved from Windows to Linux driver development. He's a lot less stressed for some reason.

    From the beginning was intended to refer to 'from the beginning of Intel's analysis'. I don't know what beginning you were referring to, but at least Intel had to have a failed part to do any analysis at all. Unless you expect them to be clairvoiant. My friend assures me he is not, he's just a scientist.

    I saw the Anandtech article, and others.

    Sorry, it gets 'worse'? Asking the court to consider any of your claims lesser than others doesn't seem like a recommended strategy. Making one claim 'worse' risks finding the others 'less worse'. Clearly, IANAL, but do I claim that when my car is forced off the road, it get worse when my coffee is spilled? Do I claim anything is 'worse'? Nope. It's ALL bad, and THEIR fault. Pay for it ALL, please, even the coffee. I don't want them settling the coffee dispute first just because it's 'worse'.

He's got an interesting case and all, but it's written up like he was a heck of a hurry to get this filed, or was just so wee-wee'd up he couldn't have someone proof it and recommend some more eloquent and sane language. Even the gas pump analogy is a risk not to be taken in a complaint. At least one judge I've known would read that and snort. And give the plaintiff stink-eye. And she's a fair judge.

    And he hired an 'independent consulting firm' to test data charges and metering? Not in that much of a hurry, unless he was beating a media deadline, and the media doesn't sleep any more. Weak.

    Or am I just too used to attorneys waxing on ad infinitum?

I do have settings to avoid data roaming and turn off sync, but I wonder if I can keep it from at least asking for a new version.
