    At minimum, this violates conservation of momentum (a feature shared with pretty much all proposed reactionless propulsion systems).

    I would not be too excited about hypothetical reactionless thrusters until one has been demonstrated, and with more thrust than would be possible with magnetosphere interactions.

    I'm always excited at any opportunity to escape the constraints of real world physics. I'm all too aware that lately all of them have been false and our current understanding is more solid than ever. Doesn't stop me hoping.

    When I saw you mutter hell on math, it reminded me of the hell known as... Spreadsheets. Especially when wanked for quest management and worse, *Mechanics*. :p

    Since you seem to have a handle on the science behind particle accelerators, what sort of range would be likely on them?

    Yes, obviously, there are ways that you can actually cool the beam and those will reduce divergence in the case where there is not a laser beam there. But that's not related to my point - that the laser itself will only stop the beam spreading out while it is there, and once it is gone the beam will continue spreading at whatever rate it was doing so before the laser was applied.

    Again, IH, I do not believe you know what you're talking about enough to pick holes in what I say. I can tell you're in parrot mode here and Persimmon is not (some of this is a bit beyond my level, but a lot of it isn't).

    (Parrot, or "script kiddie" mode is enough for most things - we can't all be specialists in everything - but part of self-awareness is knowing when you're in that mode and that you shouldn't debate from it.)

    I prefer not to continue the Mass Effect Derail further in that thread, but I tend to think that the dreadnought sized carriers might well have *been* a mistake, just an understandable one. Mass Effect isn't that far in the future, so humans would still be carrying forward their understanding of carrier doctrine from wet water navies. Certainly no other race built carriers that big.

    Wildly inefficient to use Mecha to mine limestone. Mecha are going to be huge, very costly, and not offer all that much HP. Plus the estimates we have are leaning towards months to produce each unit. If we convert it from a pit mine to something like the iron mine we can keep normal workers on it.

    We're already expecting to sell off a lot of our stuff, possibly in spring. Doing it too early is counterproductive.

    In terms of the Chesapeake facility though I expect it to fall, but it's so useful to have a port facility that it's worth rolling even low odds on it surviving.

    Thanks for the info on the newest turbofans. I've been dragged into a wikiwalk that will eat up more of my time ;p

    The latest turbofans put in the latest release of the 737-Max 8 are really pushing efficiency boundaries.

    Incidentally even a smaller 2 engine plane can outperform payload/fuel a larger 4 engine one, I have figures on that.
