You can just use long, dragging wires in space to generate current... but its coming from the kinetic energy of your vehicle, so you will deorbit. Conversely, you can pump current into the wires and give your station a boost... check out the experiment (STS-75 IIRC)
Dropping them down to the ground has the problem of needing to self-suspend. IE, a geostationary satellite has to suspend 35,768km of copper wire. That's why the space tether people are constructing from carbon fibre...
The traditional way to think about it is 'beaming' energy back to earth in some fashion (microwaves? laser? etc). But another way to harvest energy is to use it to refine resources in space... use the energy to harvest or refine near earth objects (NEO) or lunar regolith. The refined material can be very valuable (there are high concentrations of rare and precious metals in NEO's), and then shipped back to earth more conventionally. Or used to construct in orbit.
Presumption was the mortar because, as you pointed out, they are structurally more massive (thicker walled) and have a spin to them. If you can take out a mortar, the rocket, from an energy standpoint, is a piece of cake.
Check out the Phalanx LPWS... its a Phalanx gun mounted on a flatbed truck... not exactly a rail gun but pretty spiff. There are some firing videos on YouTube as well...
The event horizon for a RAM threat is incredibly short. Seconds. Depending on the scenario, if you do not get your shot off within a few seconds of detection, you are dead in the water. Secondly, the amount of energy necessary to take out a RAM is pretty low... on the order of tens of kilojoules. These facts I know from my research.
(Up until a few months ago, I worked 2 rooms over from some of the guys doing the modeling and simulation for this
particular system... this is a test bed, not the finished product)
I don't have numbers to throw at the question... yes, of course, there is attenuation. My point is, and what I do know from experience, the range to downing a RAM threat is not that far, and secondly the amount of energy you need to impart to down a RAM is not as much as you might imagine (tens of kJ).
The range to shoot down a RAM (rocket-artillery-mortar) threat is on the range of a few kilometers. Laser attenuation ovr that short a distance is pretty minimal. My master's thesis was on this concept, but swapping out the laser for a gun-launched projectile... you actually don't need that much focused energy to destroy a RAM threat mid-flight.
$15.00ish a month for US subscribers, not sure about EU. But the chinese, etc. do not pay nearly that much... they pay about $0.04 an hour. And the Chinese account for an excess of 5M subscribers. source
I'll disagree with you on EQ2 having a better housing system than UO.
I don't believe I said it was better, I just said, they had a housing system. Personally, my poison of choice is Everquest (the original). I had hopes for Vanguard (which had an awesome crafting system) but it looks like it will descend into mediocrity, sadly.
You could own a house, put vendors there to sell stuff, you had trade skills that were fully independent of fighting, you had an economy of "rare" artifacts with no use at all people just wanted them to have them, you could kill other players and take their gear.
EQ2 has everything but 'taking their gear'. EQ PVP servers have everything but 'owning a house'. Non-PVP EQ didn't have the gear stealing. And it was so much friendlier to the casual player: you could teleport to where your real-life friends were, you could play with your friends even if they played 40 hours a week and you played 2, you could macro when you were away to keep up with your friends or do things like craft armor to support a guild.
EQ has a cool system called shrouding, where a high-level player can 'shroud' into a different form and descend to a lower level; and change classes even. Its nice to play with friends leveling alts or, as you say, friends that aren't as hardcore.
Never played UO, I got sucked into EQ, just wanted to agree with you that WoW really is a dumbing down of the oldschool MMO's but that EQ offers basically everything UO offered, and is still alive and kicking (new expansion in a few months, baby! I think its #14 now...)

The problem is, different people do different things, and use different distributions. I'm using WinXP 64, and only have a few external packages loaded (Everquest, Office, Flickr uploadr, MS Visual Studio). That's it. I'm pretty nitpicky about my computers. So it stays nice and speedy. I don't get viruses / spyware behind my hardware firewall. On Linux (FC4) I use gcc and a LAMP stack for development. Just offering a counterpoint - on my box, for some reason, Windows is 'faster' per see.
Again, its all gonna boil down to who, what where and when. And a few seconds here and there really isn't the end of the world. But to reiterate, except for some REALLY stupid shit on my part, I've never had a Windows 'crash'. That includes running WinXP betas. WinVista betas. You name it.
I don't know, on the same machine, Firefox loads faster on Windows than Linux, and IE faster than Firefox under Windows. Windows boots in under 10 seconds, Linux takes a few seconds longer than that, and to a text console, not X. That's all I got for you; everything else I do is apples and oranges between Linux and Windows. And, in truth, I can't remember the last time my Windows machine crashed...
If we don't like how they work, we can roll our own.
I don't have time - or corporate backing - to roll my own. It is a lot more cost effective for my manager to spend god-knows-how-many thousand dollars per seat to get already written software (for both Windows and Linux, yes, I have both sitting under my desk).
But either way, you either didn't read the article or missed the point. He's talking low level stuff in the kernel, not application or GUI layer. The people on the LKML are apparently focused on appeasing their respective corporate interests (which, for the most part, fund their contributions) that their contributions tend to favor the enterprise environment, not the desktop.
Yar, but I'm kinda in a sticky situation, my XYL is 27:P Which I think would make her a YL. The connotation on XYL is 'former YL', and I still consider my wife to be pretty young... ah, well, as long as she never learns morse or reads/.

If you hate it that much, why are you hanging out here?
I'm this close to leaving. I keep hoping things will make a turn for the better. But it sure doesn't look like it will.
