Bezos' Blue Origin revealed!
"Scott Hedrick" wrote in message ... "Herb Schaltegger" wrote in message .com... I don't know if I'd go quite THAT far; I'm a bit of a guitar snob and I will tell you that $2,000 buys you a hell of a lot more than $1,000 in terms of materials, workmanship, playability and sound. I will say that after about $3,000 the price/performance curve really drops into the tank in terms of new guitars however. I mostly prepare legal documents. A $400 laptop can run MS Office adequately. A $700 laptop can run it fine. It just doesn't run much better by spending more money. Right, for you that's a decent trade off. For others, neither laptop would be adequate. Given the way I paly a guitar, if I spent $50 on a guitar it would be $60 too much. :-) The better is often the enemy of the good enough. |

Demonstrator with all electric (no hydraulics) actuators for engine gimballing, aero surfaces, and etc. The Germans tried a bomber on this concept during WW II; it came out very heavy in comparison to a normally designed one. I think the same might apply to a modern aircraft or rocket. People have been moving in this direction for both missiles and aircraft, although my impression is that the technology isn't yet entirely satisfactory for the fast, strong actuators needed to deal with air loads. It's been done for some in-space applications; notably, if memory serves, the Centaur on the current Atlases is all-electric. NASA was persistently *interested* in this as a shuttle upgrade -- the orbiter's hydrazine APUs are headaches in various ways -- but funding never materialized, and I'm told that the technology was always a little bit iffy. -- spsystems.net is temporarily off the air; | Henry Spencer mail to henry at zoo.utoronto.ca instead. | |

It was a big disappointment to those of us who actually expected it to produce some sort of usable scientific data which would apply to the earth. I was half expecting it to have dolphins in it. :-) Nah, they knew all along it wasn't going to work |

Which is why I think they should be looking into this as an R&D project, not a shuttle upgrade. That and I thought on the shuttle they were looking into electric APU's and would keep the remainder of the hydraulics. Not quite the same thing as all electric actuators. It may very well be that all electric actuators simply aren't appropriate for most aerospace applications, but that's why they call it R&D. Sometimes new technology just doesn't pan out.

I suspect that Moog spent quite a bit of IR&D on this, back in the eighties and nineties, in hope of getting an EMA contract for a Shuttle upgrade. They probably still attempt to market it to people contemplating building new vehicles. |

Futron is not a "space advocacy group." rest of nonsense snipped You still haven't explained why you're so invested in the notion that there is no market for space tourists that you indulge in nonsensical and narcissistic arguments about it. When I look at a company like spacedev, I see a company that would go into the red if they hired another three or four people. How in the world would you "see that"? PMJI, but paying their salaries based upon loans and not generating any revenue before they quit and therefore defaulting on the loans. That would put the company in the red. Rand, why don't you see how many banks, lending companies and venture capitalists are willing to loan money for commercial spaceflight as a barometer to the industry. I see a stock that defines the notion of high risk. Those that invest in such stocks had better be well practiced at the old pump-and-dump. Many high-risk stocks have turned into economic powerhouses, making great amounts of money for their owners. Thanks for displaying once again you economic and financial ignorance. But how many more Nukos are there than Apples? As such stocks are all about making a fast buck after some cheap hype. Nonsense. Here Rand is stating that the Dot Com boom didn't precede a Dot Com bust. rest of nonsense snipped unread. I sure as hell wouldn't lend you a dime, Rand, as you clearly are a financial idiot when it comes to managing more than your checkbook, though you probably need help with it too. Eric |
