Sure, that person might not have done anything to him personally, but they chose a "side" of society that... you know, this whole analogy is absurd. It's a goddamn PvP game, the objective being to pit player against player. Do you play CounterStrike by any chance? I suggest next time you play as one of the terrorists, you try sitting down for a chat with one of your opponents, and maybe suggest seeing who can throw a grenade the furthest (but not *AT* one another, of course!) You might get a "LOL!!" before he shoots you in the face. Probably only after, though. Quite a bunch of dicks, though counter-terrorists, aren't they!

Jumping a transport through our space as a neutral pilot (we don't know you and have no standings set) will get you killed where we hang out. Want your loot back? Sure, we'll offer it - but we'll put a steep markup on it compared to what we'd ask from the alliance. If you don't like it, stick to NRDS (Not Red, Don't Shoot, i.e. only kill hostile ships) space. On the other hand, if you want to join us, go ahead and ask - we're usually recriuting to some extent or another. We'll even take in new players and help them bet set up, which a lot of alliances have no interest in doing. Why operate this way? It's how we like to play. Don't like it? Stay out of our way (we occupy about a dozen systems, with presence in perhaps a dozen more, out of many hundreds) or get your own alliance together (or join one) and fight us. Seriosuly, bring it - the game is no fun when you have to fly 40 systems away to get an PvP.

    Not a fair statement; if that's your experience then you're doing it wrong. Outside of "safe" Empire space (and ignroing war declarations), EVE is a game that *must* be played cooperatively with other players. As a member of an alliance with over 1000 pilots, I'm far safer in our portion of 0.0 "lawless" space than almsot anywhere else - we're big enough that there's almost always a war somewhere, so even empire isn't safe. Anybody who wants to come gank me out here will have to fly through a few hundred PvP-ready pilots allied with me, though.

    Of course, getting down to your alliance's space can be dangerous, but again, that's what your corp/alliance mates are for. I'm willing to take time off to fly up to empire in a fast ship, assemble a gang, and escort everybody back down... and they do the same for me. Almost nobody ever tries to mess with 40 armed ships looking to avoid populated areas, and the last time anybody tried we killed 14 battleships in exchange for a couple cruisers. Looting the other side's wrecks, we actually came out of that fight richer, easily enabling the folks who'd lost ships to buy new ones.

    We're new enough that people do still come and attack us, but if nobody has done so in the last hour or so, I'll put together some cheap, fast-moving gang and we'll go hunting in neighboring space. Wandering off solo would be suicide, but doing it with a gang at your back is all kinds of fun and hey, if you can't afford to get your ship blown away, don't come. Nobody is forcing you to.

    Nowhere near that, sadly. Chemical rockets measure burn times in minutes or seconds. Thermal nuclear engines last longer, but still not long enough (fuel-wise), and we aren't currently developing them. Ion engines can last that long if they have a long-lived power source and enough fuel (yes, they still need some reaction mass) but their thrust is crap; you're unlikely to see 1/1000 of 1G out of one. VASIMR is more powerful and more efficient, but it too needs some fuel... and it reqires a much more powerful energy source (which still needs to run for a year uninterrupted). Nothing we've yet put in any spacecraft could keep even a fairly small VASIMR running continuously; it'll probably take an active nuclear reactor to do it. In return we might see... about 1/1000 G of acceleration.

  5. Re:Total power on Successful Test of Superconducting Plasma Rocket Engine · · Score: 1

    Liftoff with a VASIMR would require pushing it WELL above the current power limits of any design on the table. The problem is that making the exhaust go faster makes the ship more efficient (less reaction mass needed for a given thrust), but since energy is proportional to the square of velocity (while momentum is only linearly proprtional), and since the mass exhausted is truly miniscule, it would take really incredible amounts of energy to produce enough thrust for liftoff. Pumping out more reaction mass at a lower velocity works to some degree (this is how chemical rockets work, and VASIMR is designed to allow increasing the fuel rate to get some increase in thrust in exchange for less specific impulse) but VASIMR really isn't designed for high mass flow; the baseline speed for the exhaust is measured in 5 digits of m/s. The propellant is heated using RF energy; it basically turns a flowing stream of matter into plasma using a microwave oven. The amount of matter you can do this with is pretty limited.

    Actually, to the best that I ever understood it (almost nothing; it wasn't ever explained very much) it's the closest to an "impulse engine" from Star Trek the we've ever seriously considered. For anythign like a "true" impulse drive, you'd probably need to get the fuel mass up a LOT higher - kinetic energy may go up as the square of velocity, but momentum is only lineraly proprtional, and the mass ejected is really, REALLY minimal - but the theoretical speed capabilities aren't too far off.

  7. Re:High Thrust, High Specific Impulse (Isp) on Successful Test of Superconducting Plasma Rocket Engine · · Score: 1

    Actually, given the incredible thrust of a NTR, I can see them being used for short (objects in Earth orbit) trips, rather than designing your spacecraft for switchover to a more efficient engine. That said, the fact that a VASIMR can maintain thrust all the way would make them faster than NTRs for any sufficiently long trip - maybe even for just getting to the moon and back; anybody want to do the math on that?

    One advantage that a NTR could offer is maintaining "gravity" from the trust. If you can somehow keep it fueled enough for even a small fraction of 1 G of thrust on a substantial voyage, that may well make it the better option for transporting humans over interplanetary distances (in the somewhat distant future).

  8. Re:High Thrust, High Specific Impulse (Isp) on Successful Test of Superconducting Plasma Rocket Engine · · Score: 1

    You'd still have to haul around a LOT of fuel; they can't sustain thrust for anywhere near the time that a VASIMR could. This is not to say they aren't fantastic, and they CAN produce enough thrust for takeoff from earth (something no rocket using an ionized reaction mass - like a VASIMR - is ever likely to accomplish). Once you're in space, though, a VASIMR is more efficient, lasts longer, and (in the long run) allows much faster travel.

  9. Re:High Thrust, High Specific Impulse (Isp) on Successful Test of Superconducting Plasma Rocket Engine · · Score: 4, Interesting

    Both are, to some extent. You (and Wikipedia) are correct in that VASIMR engines can change between high-power and high-efficiency (think of it like changing gears in your car; you're much more fuel-efficient cruising in top gear, but can accelerate much harder in low gear). Indeed, that's a fundamental characteristic of the engine, and explains the first two letters of the acronym (VAriable Specific Impulse Magnetoplasma Rocket). However, the OP is also correct in that VASIMIR engines are extremely efficient in general. Part of this is due to their variability - as with a car, the efficient way to use a rocket is to increase its specific impulse (gear ratio/fuel efficiency) as its speed increases (currently no other rocket engine that I know of can do this). On the other hand, look at the high-end of that specific impulse - it's several times what our best Ion drives produce, while also putting out substantially more thrust. Theoretically, VASIMR engines are strictly superior (in terms of thrust and SIP, at least) to ion engines.

    Of course, even at maximum thrust, current VASIMR drive designs produce *maybe* enough thrust to lift about .5 kilos (call it 1 lb) into space from the surface. Since the engine itself masses far more than that, you'll still need something with really high thrust to get it into space in the first place. Based on that, chemical engines will probably be around for a while, unless we can whip up a space elevator while we're at it. Theoretically you could run more power through a VASIMR and get more thrust, but I suspect the practical limit on doing so is far less than would be required for liftoff (if you could even get it to operate in an atmosphere). Even without that, though, it would be an incredible boon to intrasystem travel, or for station-keeping engines on satellites.
