maintaining a vaccuum would be pretty difficult and expensive.
Actually, a vacuum can be maintained with a good gasket. It is only 14 psi pressure differential, which is not anywhere close to say, submarines face. (Subs will run up into the hundreds of psi's or even more)
Instead of a membrane, escape hatches on the bottom every few feet that fly open with a push of a button or something. A person will stay consious and functioning for 10 seconds in a vacuum, enough time to get to an escape hatch. A person in a vacuum can live for around 2 minutes.
At any rate though, decompression would be very rare. How often do airliners decompress?
My neighbor's garage door has a similar problem. Somebody one block down must have a garage door frequency the same as hers. Once in a while her door will go up or down on it's own.
RTG (radioisotope thermal generators) are very safe. A rocket that carried one blew up in the 60's. The RTG survived perfectly intact. They are even built better today. You have got to understand that these things are strong. They are designed to withstand reentry, an exploding rocket, and crashing into the ground
This uses interference to create colors. Holograms also use interference to create the 3d images. Could this interference display technology be utilized to produce holographic displays?
I have two computers: Athlon XP 1600 running linux, and a 633 Celery running XP. I have photoshop installed in the older machine, and it works fine for my purposes. Unless you are a graphic designer, I can't really see the need for a 3 Ghz chip.
The speed is for Clippy, not YOU... he now is 3D ray-traced and has more artificial intelligence built in!
I saw this poster (Microsoft-sponsored) in my CompTech room that detailed major advancemencements in computing in the last 100 years. In 1997, it said: "Microsoft introduces artificial intelligence into Microsoft Word." Heh.
Now they got the very, very annoying search dog in XP that I can't get rid of.
I tried to run UTk3 on my XP 1600 last night under 1200x1600. It raped my computer!;-)
I'm hoping the Opteron actually comes out on schedule or else I might be forced to switch to the Dard Side. (Hey, I need to be able to run Doom 3 when it comes out.)
Think of it. Not being confined to a cramped 1600x1200 screen....
I cope with the 1200x1600 by pretending I'm viewing the world through futuristic video techno-goggles.
Seriously though, I think the real killer ap would be wall displays. A 10k x 10k display that covering all the walls of a room, converting it into a holodeck (kinda), providing nice, very energy efficient ambient lighting, or just making for some nice wallpaper.
You could use some form of sensor ($5 webcam mounted on a helmet) to detect the location of a single viewer and match the image to their location based upon the current shape of the suit, but you couldn't match the image to more than one viewpoint with this technology.
Holographic displays have been developed. (Shitty ones, anyway) But to render a panoramic 3d image around your whole body would take more computing power than Deep Blue. (Note: I'm not talking about the 3d monitors that are available now. This is true 3d which changes perspective as you change your angle.)
Actually, the space tether/elevator part was science fact. Didn't you read the stories a few weeks ago about how a 50 k mile long space elevator/tether was being planned for 2015?
It uses a recently developed carbon nanotube composite which is extremely strong.
In order for the moon to be a useful source of raw materials for spacecraft, we'd have to do an unbelievable amount of work: smelting, refining, fabricating, and so on.
Manufacturing aluminum for the L1 station would not be practical on the moon. However, getting water would be very practical. (There are some crater rims which do contain ice.)
In addition to drinking and such, you can also use water for rocket fuel by splitting the hydrogen and oxygen with electrolysis using electricity from the plentiful sunlight in space. (Which means Mars missions would be much more practical, because you wouldn't have to haul the fuel from Earth.)
I imagine in the more long term, you could have a pretty good civilian transport system. (Like quite a bit more long term. Maybe 40 years, optimistically.)
A few carbon space elevators could be built for less than 1B dollars each (the ones featured on/. a few weeks ago). could provide relatively inexpensive space access for normal people. If each elevator cost 1 billion dollars and could haul up 250 people per day, you would only need to charge $1500 per person for a trip to geosynchronous orbit.
These carbon nanotube tether would extend out to about 50,000 miles, or about twice GEO orbit. So you could fling spacecraft toward the moon and mars and such.
Anyways, remember when Honda and Nissan were crap in the 70's? Then NAFTA was signed and more than a 100,000 manufacturing jobs in the Southeast of America went south with the now famous sucking sound
Japanese cars weren't crap at all in the 70's!!! It was just the American perception of Jap cars. My parents bought a Datsun in 72 and it ran just fine until they sold it in '87.
Because it didn't make national media for some reason or other, so from most of us, an excellent percentage, it was still a secret.
The gov't'wouldn't care if an average citizen knew what they were working on. For example, it would be no strategic disadvantage for me to know, for example, the existence of a hypersonic ramjet bomber. However, it would be bad if say, North Korea had this knowledge. They would be able to devise defensive measures against this craft.
Secrecy is not to keep shit secret from U.S. citizens. It's to keep it secret from foreign intelligence.
The noxious chemicals are dissolved in the water vapor. Therefore, when the water has condensed out, you have no noxious chemicals. Also, you would be able to smell it. The hydrogen gas in the bag is completely odorless.
Better yet, magnesium, fire, and water. The 5,000 degree flame dissassociates the water molecules into hydrogen and oxygen. Fun.;-)
Also, drano and tinfoil produces hydrogen. The best way to do it is to put lye powder (seems to work better than drano for me), water, and tinfoil in a PLASTIC gas can. Then, attach the nozzle to a hose. The whole thing will heat up and send noxious steam and hydrogen through the hose. The bad stuff condenses in the hose and you are left with very pure hydrogen.
You can mix the hydrogen with some air to make it explode, or you can let it float. Also, you can breath it. That produces a similar effect as helium

It like didn't completely get raped. But the framerate was really, really low.

It's VERY hard (is it even possible to get 100W!?) to get any real power out of thermocouples though.
Very hard, but not impossible. Spacecraft using RTGs use thermocouples heated by isotopes to provide a few hundred watts of power.
These have been around for years. This is just the reverse of a Peltier cooler. Havent you all ever heard of thermocouples?

Timothy should commit suicide on-line with a Bushmaster rifle and a webcam. He can make it his final story.
And it will be his first story that isn't a repost!
270 million people in a fairly free society don't exactly keep secrets well.
Exactly.

All the porn stars are gonna copyright their bodies, and bill you everytime you fantasize about them.
