    All that this means is that deep down, Elon Musk doesn't have any faith in kindness and goodness and altruism, nor does he understand the tit-for-tat principle of reciprocity: First do onto others what you expect them to repay you with in turn.

    And what does that have to do with so-called "AI"? My view is that it is a fantasy to assume that if you create a powerful being, then it will treat you morally. Tit for tat fails when one player is powerful enough that they don't have to play the game and/or don't care about the consequences that get imposed for engaging in non-cooperating behavior.

    Not surprisingly, given that a number of successfull people have, shall we just say, "unusual" mental build-ups and motivational matrices?

    A successful person is someone who isn't consistently a failure. The real "unusual" people here are the ones who never succeed.

    A doubling of atmospheric CO2 results in something like a 1% change in the Earth's temperature due to heat retained (at least as claimed by the IPCC). So when someone says "The heat isn't going anywhere", they are a bit wrong - only a small extra portion of heat is being retained for a time. There's also the matter of whether the heat is actually being retained in the first place or being emitted into space.

    "Concorde wasn't a destination"

    Neither is space. It's baffling to me how you space fans can't grasp that.

    Space is not a destination, it is a universe of destinations. Obviously, only a few destinations are within near future reach such as Earth orbit, the Moon, Mars, some asteroids, etc. And even on the slim basis of what we currently know, there are a lot of people who are interested in visiting those destinations or in creating new destinations (such as orbital space stations). These are the space fans.

    As I see it, peoples' wealth continues to grow while the cost of access to space declines. Eventually, it will get to the point where some of modest means can save up for a trip to space. When that happens, I think we'll see a lot more going on in space just from people who choose to visit various destinations in space.

  12. Re:Why Cold Fusion (or something like it) Is Real on The Physics of Why Cold Fusion Isn't Real · · Score: 1

    I apologize for that. I note though that Dr. Storms baldly asserts the claim that there are hundreds of such experimental attempts, a bunch of which are alleged to be successful with "large amounts" of power/heat produced (using his own book as sole reference). I can grant the former, since the attempts are public record. The successes though? I have to see more solid evidence of these than I've seen so far.

    For example, the most successful experiment to date (Andrea Rossi's nickel-based LENR fusion) involves an experimental setup with plenty of opportunity for fraud and deception.

    Meanwhile the experiments that Storm details are so marginal, that they attempt to determine the presence of fusion based on trace element analysis or correlation of high noise observations (like the ratio of estimated energy production to helium production). Reproducibility remains a huge problem throughout this work.

    Don't get me wrong. Cold fusion most likely happens naturally just due to quantum tunneling. The whole point of these experiments is to create contrived situations where the quantum tunneling resulting in fusion happens far more often (many orders of magnitude more often, perhaps hundreds of orders of magnitude more often). Even if we are to eventually have highly successful cold fusion widely used for energy production and other uses, we'll still transition through this murky region of uncertain experimental evidence.

    And it's worth noting here that despite whatever the American Physical Society or the US Department of Energy has said about cold fusion in 1989, research continues. They aren't really in the way now. I don't expect conservative, perhaps hide-bound institutions to embrace every new concept that comes along, even if in theory, that's their job.

    Here's the thing. What is valuable to you? Dumping lots of mass to the Moon? Or spending a few years extra? Operations (the cost of monitoring and planning an ongoing mission) tends to be rather cheap compared to R&D or the cost of deployment right now. The Moon in particular can host near real time teleoperations meaning that even if labor on the Moon is extraordinarily expense (or even non-existent), any such expedition can tap labor from Earth at vastly lower cost.

    Further, there's probably a happy intermediate state where particularly difficult to manufacture, but very low mass stuff like ICs or components made under extreme conditions (like small high temp parts or exotic materials) can be shipped from Earth while most of the mass can be constructed on the Moon.

    And it's worth noting here that there are already plans for making a basic machine shop from scratch. One needs to be able to construct a furnace and have access to sufficient metal. You can construct human operated machining tools from a lot less starting technology than what I'm proposing.

    *sigh* This is one of the biggest pieces of misinformation about solid rockets floating about out there, spread and repeated by shuttle detractors in a cargo cult like fashion until it's now regarded as a law of nature. What most people (including engineers who should know better) don't realize is that you don't need to shut them down in the first place- you just need them to produce net zero thrust.

    For "misinformation" it is quite correct, the booster is still burning even if it is producing net zero thrust. For example, if there is premature ignition of a solid rocket booster on the launch pad, then that SRBs will burn out no matter what you do with it, even if it is producing net zero thrust. And a launch pad isn't designed to hold a burning booster for several minutes even if it isn't producing net thrust.

    I'm sure that NASA has thought this risk through entirely, but it is still there. The problem doesn't go away just because there is a means to make the booster produce no net thrust.

    Some things just don't break down into little pieces in an economical fashion.

    Then I guess we better focus in the near term on things that can be launched in small pieces. I'm not going to support, say, a 200 ton to orbit launch vehicle just because someone can think of peculiar payloads that a 20 ton vehicle can't launch. Capability != utility. We still have yet to have a reason for putting that 1000 ton NPR in orbit.

    And I'll note that one can get decent performance out of a variety of competitive propulsion/powerplant combinations which can be broken down into small pieces.

    Finally, if we are going to launch large unwieldy structures into space from Solar System bodies, then the Moon is a better place to do so, both because delta v is much smaller, but also because there is no atmosphere and hence, a much weaker restriction on fairing size (it just needs to be able to withstanding the acceleration of launch without damage). A near Earth asteroid might even be a better choice, especially if it can be moved to Earth orbit first.
