Re:Job rating"...right up there with "Beer Taster" at Budweiser"

Postponing the inevitable
This is just avoiding what many people see as the obvious conclusion: the space shuttle in its current incarnation needs to be replaced. It was designed before I was born.
Unfortunately it looks like NASA is moving in the wrong direction, cutting the funding from their shuttle replacement project. Of course, I'm all for making the existing shuttles safer, and what they're doing now is a good idea. -

You know, I submitted this same story, based on the Popular Science article about WASTE: a secure, private P2P system. I never get my articles published. Who's palm do I have to grease to get a decent article put on Slashdot?!?

Re:Made or simulated?
The software he used, X-Plane is being used by commercial aircraft and spacecraft companies. Most notably Scaled Composites for simulating SpaceShip One and Carter Copters for simulating their helicopter designs.
Not to mention Jetstream people using it in a full-size Jetstream simulator instead of official replacement components (which are way too expensive) - and that X-Plane is certified for training pilots by the FAA.
Popular Science has a good introductory article about X-Plane.
So yeah, I'd say that for a ballpark simulation - results obtainable in that program are probably damn close to what you'd get in real life. Especially since it's already been used to help design at least one real spacecraft. -
Re:Aerospace analysts are always too optimisticI have to agree to a large degree with this poster. Aviation followed a very exciting first 70 years, very similar to what we are now see in the personal computer industry. The last thirty have shown it to be a fairly mature technology. The 747 was designed in the late 60's and is nowhere near the end of its life cycle. The Airbus 380 has not yet arrived, and will still have to prove its reliability and economy of operation. Even so, the 380 has a familiar look, and while large, is hardly radical. The fasted plane ever publically acknowledged, the SR-71 blackbird, was also designed in the 60's.
Security and speed of boarding become more important in the airline equation than ever before. Marginal increases in speed, do little to improve the overall perception of the flying experience. Radical changes in speed, while exciting to contemplate, will require decades of testing before being considered safe enough for commercial adoption.
Pilotless craft might make sense for small planes where the pilot's pay is a huge fraction of the total transportation cost, but will take much longer to be adopted in 200+ passenger craft, even if the pilot is largely redundant.
That all said, Flying Wings is where I see the future of flight going. That and computer assisted small jump craft of various types. See this recent Popular Science article on flight. There is an expression in military circles when it come to evaluating new aircraft: "looks right, flies right." Looking at the envisioned commercial passenger flying wing concepts in the Popular Science article, one can't help but feel this aircraft has the right shape. Kudos also to whomever created the pictures in the magazine, because at first look, you would swear these beautiful behemoths are already lifting off from tarmacs in Tokyo.
Rather than obsess on airspeed, I think our focus should be on making the trip to the airport fast and easy, and of course the boarding fast and easy. Imaging a airport where it was more like a trip to the local cineplex. You park your car close to the terminal minutes before your flight. The car is moved inexpensively for you to a storage lot (rather than park in the hinter lands and wait for a bus). Or better yet, you have had a quick comfortable ride (mag-lift or not) from a city center, directly to your terminal. You are a frequent traveler, so you have undergone a rigorous pre-screening procedure once a year, and can now be biometrically scanned in quickly for a hassle free entry. Like first class seating, biometric priority boarding could be a real money maker for the airlines. Once on board the flying wing, space is not as much a factor as in tube based airplane designs. Weight is the limiting criteria on the 800-1500 seat flying city, not space, so everyone has space to stretch out, and get comfortable. Even reclining to a complete sleep position, to just sleep through a long trip, very much like the golden age of rail. Personal video screens for each passenger will be considered a must, and you will have a screening choice of dozens of first run movies at a cost similar to seeing it in the theater. Your screen will also allow web-browsing, and by the time you update your journal on
/. , and post a few comments, it's time to deplane.Making airplane fuels more environmentally friendly should also be a priority this century. A lot of fuel is used on take off, so how about mag catapult launch? Perhaps planes that use microwave beam power; using conventional fuels only to get airborne, or for emergencies. The rest of the trip a series of boasts from microwave beam boast areas. Ah, but I'm getting decades ahead of myself, and the crystal ball always grows murky 10+ years out.

Re:Moore's law is NOT obsolete
Oh I forgot to mention... Popular Science 'Brilliant 10' award last November 2002 highlighted how nanotechnology which was being researched at Harvard University by Charles Lieber might address Moore's law. Hey spoke of how the current state of semiconducter manufacturing would be considered crude/clumsy if they can perfect the techniques they are working on.

Re:A Bagatelle
This is frustratingly typical of what passes for journalism in this world
The PopSci page linked in the original /. "story" referred to Bombardier as a "company that designs ATVs and jet skis".
That's true, but they also manufacture locomotives and prop and jet aircraft (including water bombers and the famous Learjet), leading me to believe that the company has some serious engineering capabilities beyond recreational vehicles.

Doesn't seem to be much of a market for this
I agree with some of the previous posters that there is a very limited market for this. Sure everyone wants to travel halfway around the world in 2 hours, but who can afford it? I think something like the Boeing 7E7 Dreamliner is much more likely to succeed. Most people will choose a more reasonably priced luxury flight over a hypersonic flight even if it does take twice as long.

Anything that saves me from being rectally probed
...has to be the best of whats new.
It doesn't come with Raquel Welch, but researchers at the University of London have brought the dream of Fantastic Voyage one step closer. The first video-equipped ingestible capsule capable of being piloted is about half the size of a grape and has electrodes on its outer surface that deliver a series of 5-milliamp jolts whenever physicians press a remote control. The charge triggers a small muscle spasm in the intestine, which nudges the capsule forward or backward. Previous incarnations simply went where the body took them. This one allows doctors to get a longer look at suspicious-looking areas. Earlier this year, one of the researchers became the first human guinea pig to try the capsule. It was a success, and more human tests are on the way.

Re:don't you love catching a dupe?

Re:who tends to fund these projects?
I don't think anyone knows for sure but Paul Allen is speculated to be the backer behind Rutan. The article goes on to say that Internet tycoon types with entirely too much money on their hands seem to be the primary funders of this kind of thing.

The worst of the worstPre-med student Stubbins Ffirth (1784-1820) ate, drank, and breathed the blood, urine and vomit of yellow-fever victims (he also dropped the fluids into his eyes and worked them into cuts on his skin). He didn't get sick -- the patients were in a late, uncontagious stage -- so he erroneously decided the disease's cause lurked elsewhere.
Now who would even think of doing such things????

Retail hydrogen outlet opens.
If you're interested in hydrogen you'll probably be interested in an article in Popular Science on how the first retail hydrogen station is opening in Iceland. Makes sense since the country has few cars and lots of geothermal electricity coming from the Reykjanes geothermal area where the North American and Eurasian tectonic plates meet.

Re:V1
The first scientists to recognize that rapidly pulsed detonations might be used to create thrust were probably the Germans, who developed the V-1 "buzz bomb" in the 1930s. "The Germans attempted a detonation with the V-1 but never got it," says Chris Brophy, a propulsion research professor at the Naval Postgraduate School in Monterey, California. "The V-1 was a pulse-jet, more of a high-speed deflagration."

no thanks...
I am more worried about the 2005 law that requires GPS/triangulation in all cell phones for 911 call locating. Here's a link to an article in Popular Science about China and how people were using their cell phones to find out which buildings were infected with SARS.
People play a game where you "kill" a nearby person after you locate them using your cell phone equipped with GPS. Just what I want, ANYONE to be able to locate me on the street (opt-in service or not isn't my point).
The first major wave of location services could beam to the U.S. as early as Christmas, when 44 percent of the nation's 149.2 million cellphone subscribers are expected to be traceable, according to the research firm In-Stat/MDR.
No thanks, I would prefer to die after placing a call to 911 rather than have whoever decide that they want to track me via GPS/triangulation.
Live free or die.

Neat related article.
While the photo on the BBC article shows a "backpack" with hard wings sticking out of it, the description (especially that of his legs getting tangled in the rear wings) sounds more like a "Birdman" type suit.
Popular Science did a great article on gliding/sky diving with wings featuring the Birdman suits. Read it here.
This article has some good info that helps answer comments made below about diving with wings not really being free-fall, but in fact being a form of gliding.
-
This seems more like 'skydiving'
Here's a couple of guys that added wings to their sky diving suits so they can glide. The wings are made of fabric and inflate like a parasail. A pair of wings fit between each arm and torso and a third wing between their legs.
Apparently, they were not the first to sky dive with wings strapped on. Of interest is the survival rate of people who have tried this in the past: something like 4% if I remember correctly.

Re:Here's my question ...

Actually, in the year 2003 press coverage has started to pick up. If you pick up a July copy of Popular Science or Wired , the cover stories are about the X-Prize. And I'm certain that as the X-Prize teams near their launch dates, press coverage will pick up dramatically. And once the X-Prize is won -- well, that will be interesting.

Re:Are Competitors Building Dead-End Technology?
Actually, I read in a PopSci article (right here) that Rutan does have plans for the SpaceShipOne/WhiteKnight, but that he wants others to build and commercialize them:
Rutan's historical model is Wilbur Wright's tour of France in 1908, which sparked tremendous growth in the industry. Rutan wants SpaceShipOne to kick-start a similar burst of innovation. Hence his ambitious post-X-Prize testing and demonstration plan: Fly every Tuesday for five months, 20 flights in a row on schedule, to determine the system's cost and reliability. Though he envisions everything from 10- passenger suborbital tour buses to a giant White Knight that uses eight 747 engines to launch a 300-ton spacecraft, Rutan says those are for others to build: "The Wrights didn't build the world's first airliner--they didn't need to," he says. "I hope people don't expect me to certificate a spaceship and offer rides. I want to be doing something more exciting by then."

Settle down
Popular Science had an article on this months ago. Then they recently had a followup where a newer version of the system actually somehow eliminated the person's body from the picture; all you (the operator) could see were the guns, etc., superimposed on a generic body.

Re:2020:Fuel cell cars - FALSE.
...doesn't the result of splitting H2O using another energy source result in more energy than was used to do the splitting? Not unless I'm miss-remembering the laws of thermodynamics (you might be thinking of potential energy). Thermodynamics
And I don't agree with your opinion that cars would be 10-100 times more expensive, maybe initially. Look at all technology how prices drop real quickly. The problem isn't the technology as much as the materials - you need a high quality electrolyte membrane between the electrode and anode. This means your materials to make the cell are made of expensive metals that aren't dependant on technology. They break down, bond and degrade under the performance requirements of a car.
In the interest of exploring the current potential cost of a fuel cell power plant I'll give you an example -
fuel cell
Here's a currently available home fuel cell technology that provides 1.2kw. For $8k. The EV1 (ford's electric car) uses 102 KW for roughly 137 HP. To power this car with a fuel cell you'd need 82 of these units, running about $680,000. Not including the cost of the engine and 'carrying case' - the seats, body, breaks, wheels. The cost of the hydrogen (note that it's derived from natural gas or PROPANE... a petroleum product, not electrolyzed water) is $100 per bottle. That means a tank of gas for those 82 units powering your car will run $8,200. Ouch.
How many technological breakthroughs in materials and science will we need to make that fuel cell cost the same (and weigh less) as the batteries in an EV1? Even with Moores Law (technology doubling at half the price) we're looking at roughly 12 years. But since fuel cells are dependant on materials sciences (not technology), Moores law will probably be a bit slower.
I'm a big fan of the fuel cell, it's just that it's touted benefits are a far... FAR cry from reality. It's like the 'American Idol' of the energy world - a lot of hype, but talent? Not so much. (It's funny, I held the same position you do about 2 years ago. Someone challenged me, I got a stick up my ass and tried to prove him wrong, and in the process swore never to admit to him that he's right. ;))
One other thing to consider - lead acid batteries can be recycled with water cheaply. Fuel cells... pretty much can't unless someone's figured out how to unbond gold from nickle. -

Re:using air currents to regain altitudeAside from the obvious comment that NASA surely knows what they are doing (more of a conversation stopper than anything), I think you miss a few points.
First, in reference to your comments on structural and weight limitations, the actual force born by the wings is far less, since there is far less gravity. In addition, while the thinner air is certainly a hindrance to how much lift can be acheived with the same area, it also means that the stresses that must be absorbed from turbulence and the like are probably a lot less.
In reference to unfolding wings, these have, I recall, been tested on Earth, so if they work in our dense air and stronger gravity, they should be fine on Mars. If I knew a link I'd post it; you can probably find more with google.
Finally, you talk a lot about control system algorithms. However, there are a number of reasons that Unmanned Autonomous Vehicles are simpler when flying than when driving. There are a couple of relevent articles in this month's Popular Science, as well as a very good one in the New York Times magazine from a few weeks ago that I just finished reading. If you think about it, the amount of leeway available in the air is far greater than that on the ground; whereas a car driver must maintain precision navigation within a few feet on a road and avoid obstacles and the like, a pilot can, during cruise, simply trim out the plane's elevators, maintain a proper heading, and get by without even an autopilot. If he drifts off by a few hundred feet altitude or a few degrees heading, it doesn't really matter. This is why we already have numerous UAV's in the air in the military (such as the well-known Predator drone) and why Boeing 777s and the new Airbus 330 (isn't that it?) both can supposedly fly without even needing a pilot, in an emergency.
In comparison, DARPA is working with a few contractors to develop UAV ground vehicles, but is really nowhere near production stage.
My knowledge about gliders specifically is limited, my personal experience being limited to powered planes, but I would imagine that with a fair level of accuracy, finding thermals and gaining altitude should not be all that difficult, since most of the control software already exists in some form or another.

MASSIVE AI
They can react, fight and make logical decisions based on inputted given data. The program is so details that agents can get dirtier as the battle progresses.
Not a very detailed or well written article. There's a slightly better one on Popular Science.
From Pop Sci:
Massive characters, or "agents," function as complex beings subject to physical forces, with specific body attributes that range from the biological (short, good eyesight, dark skin) to the behavioral (aggressive). These features govern a Massive character's ability to generate credible motion. Each character is assigned a host of potential actions, as many as 350, each about a second long (sword up, sword down, step forward, step back). How these actions play out is determined by the character's brain, a tangled web of anywhere from 100 to 8,000 behavioral logic nodes, which provide the rules that allow each character to perceive, interpret and respond to what's happening around it: to make decisions and act. These nodes group into rule collections which control aggression, fighting style, movement across varied terrain, and a dozen other factors. Regelous originally tried to use pen and paper to sketch the relationships between nodes in a character. "It got chaotic very fast," he says, and Massive designers now use a special graphical user interface to connect nodes and create an agent's brain. A fully formed character--a map of its tendencies, its personality, if you will--looks like a huge, multidimensional spider web on the screen.
It sounds to be like a they used fuzzy logic neural networks. Interestingly enough, the battles would resemble Koza's Genetic Programming paradigm. Randomly generated orc programs, represented by tree structures, selected for fitness by success in battle. This would also explain how agents can get dirtier as the battle progresses.
