  • Commented on Unsustainable Interstellar Civilization, Hotspot Colonies, and Dwarf Culture
    Ok, I disagree with a few things you say, but isn't it kind of beside the point? We're world building a FTL drive. We want to use as much physics as is practical too help with suspension of disbelief and...
  • Commented on Unsustainable Interstellar Civilization, Hotspot Colonies, and Dwarf Culture
    I have no idea if this is what @pigeon has in mind, but i can tell you how gravitational potential is usually defined for orbital mechanics calculations. 1. If we need a universal reference frame, then we define that an...
  • Commented on The Pivot
    "archeaometallurgist" Oh, fun. What region and era do you specialize in? As for the Cynic's comment, perhaps they were thinking more of the tendency of the copper and tin oxides to form a weak passification layer? Not sure what grades...
  • Commented on The Pivot
    As an upside, that's a step to renaming it the Department of War. (Oh wait, that's not much of an upside dispite being a bugbear roud these pats.)...
  • Commented on The Pivot
    I didn't realise that you were commenting on that specific spelling as it seems less of a backronym than just a change in spelling once the word lost its association with the acronym in the general conscious. I apologise. (Just...
  • Commented on The Pivot
    Godspeed. I would dearly like to read a slightly less scrambled version of the word salad, but sadly don't have the cognitive runtime/investment nessesary to grok the references. The latest spam has been deliciously unobfuscated. @Ọya-Iyansan >*watches everyone ignore the...

  • Commented on Solarpunk rising, or how to turn boring bureaucratic meetings into creative fodder
    I've biked to work in Minneapolis in the winter. It's not fun some days, but usually doable....
  • Commented on Solarpunk rising, or how to turn boring bureaucratic meetings into creative fodder
    I know that your situation was just an example, but you got me thinking. So, at the risk of derailing... With fresh water in a polymer or ceramic main I would be more worried about service interruptions if the main...
  • Commented on Why I barely read SF these days
    How long does it take Chicago to plow the streets that all this dibbsing with old furniture is nessesary?...
  • Commented on Why I barely read SF these days
    There is the same problem when considering how to tote around hydrogen for fuel cells (a bit off topic sorry). The DOE rule-of-thumb for high pressure storage is 6-8 wt% H2 for 300 mi range. (that's weight percent of the...
  • Commented on Why I barely read SF these days
    The biggest problem is it implies that the battery actually has that capacitance. Mostly I'm just confused as to why you would try to assign an "effective energy storage capacitance to a battery when using energy storage would work just...
  • Commented on Why I barely read SF these days
    I'm not sure what you were trying to compare, but it doesn't make much sense to say that a battery contains capacitance. Capacitance is a property of capacitors. I suppose all real batteries will have some equivalent parellel capacitance, but...
