  1. I dont have hosses at my ksc

  2. Orbital solar collectors can't avoid the dark. If you put them in geostationary orbit so they can connect to the same ground station, then they'll be in the dark a some amount of the time. If you put them in any other orbit, they'll not only be in Earth's shadow some of the time, but you'll also need long chains of ground stations all around the world under their paths. Ignoring the diplomacy needed to allow such sharing, each such ground station is a discrete target requiring a pretty tight beam and the ability to switch it rapidly from 1 station to the next without scorching the space in
  3. It'll be interesting to see how being based at Woomeranga influences things. Good luck!
  4. And particle beams don't work that well through the atmosphere, so the beam originates somewhere in vacuum. Which means it can at least obliterate every satellite its owners don't like. But, you've still got to concentrate the energy into a beam (to prevent most of the power from being wasted) and aim it at a relatively small spot on the ground (where this beam can be put to use). And it has to be considerably more intense than sunlight or ground-based solar panels would do just as well and there'd be no point in putting the panels in orbit. So no matter how you slice it, you
  5. It's not the ease of making it, it's the ease of using beamed power as a weapon. Lets say you only fuel an Orion out beyond the Moon. The skipper goes rogue and starts shooting nukes at Earth. They'll be several days in transit at least, plenty of time to shoot them down before they arrive. With massive lasers, you can just reorient a mirror here and there, and POOF, instantly vaporize any target you want. No way to stop that. This accidentally happening has always been a major downside of putting massive solar collectors in orbit to beam power to the ground. If the platform wobbles
  6. A couple points I haven't seen mentioned on this yet. First, when setting up transfers by hand, it's often easier to set up any correction node once you're outside Kerbin's SOI, just due to how patched conics display. And, when you're still in Kerbin's SOI, any up/down adjustments you make are relative to Kerbin, when what you're ultimately needing is relative to the sun. This can sometimes be confusing, so it's generally easier to wait until you're outside Kerbin's SOI. Also, prior to the relatively recent addition of the maneuver node editor box in the lower left corner, the interfac
  7. I was unfamiliar with the liquid core versions so point taken But using molten salt to cool a solid core (also called MSRs) have been around a long time. Some Soviet subs reportedly had them. Yeah, this type of reactor can't be a torchship because the fuel isn't macho enough. The fuel properties you outline are the exact opposites of what you want in a rocket engine. It might work well to power a VASIMR, though.
  8. To be more precise, the game doesn't care which edge of a wing part faces the wind. It can be any edge or corner, the result is the same. Also, the wings have a symmetrical section so have no top or bottom. So, in terms of building a wing out of multiple wing parts, you can orient the parts however you want to get the desired overall shape. That said, wing orientation matters in the pitch axis. Due to having symmetrical sections, wing parts can't create lift from an airfoil section so have to be at a positive angle of attack to the airstream to create any lift. You can either build t
  9. Again, um.... no. The hard thing about conventional reactors was designing a controllable core that wouldn't explode or melt without a long chain of unlikely events happening. Once they had the core design, everything else was existing technology, or nearly so. For instance, in a PWR, the most extreme water conditions for the coolant are about 2200psi at about 650^F. This is actually easier to handle than the 1200psi, 950^F superheated steam then being made every day by the thousands of standard oil-fired naval boilers of the 1950s because steel starts getting soft above 900^F. (red heat),
  10. Um, no.. Not. At. All. The NSWR has NOTHING in common with a normal (or even molten salt) reactor, other than they both involve uranium. Thus, the challenges are ENTIRELY different. In the conventional reactors you mention, the uranium is solid, in the fuel rods, and doesn't move. The pressurized water or molten salt is merely coolant, absorbing heat from the solid core and carrying it away to keep it from melting. As this fluid circulates through the fuel rods, it picks up bits of radioactive solids so is usually not the actual working fluid---otherwise you'd contaminate the tur
  11. Thanks for checking. I have both MH and BG but, as per the installation instructions in the OP, I also have Making Less History. The Lua base actually works for launching, but not recovery. The main problem, however, is that once you launch a ship from there, and switch focus away from it, the universe implodes. I also just noticed another problem with the Lua base since the most recent KK update. The comms network no longer links to Rhode and its extra ground stations, but only to Lua's tracking center. This is very annoying. I'll try shutting down the Lua tracking station
  12. Well;, you believe crazy Zubrin, I'll wait to see whether the justifiably skeptical, arguably saner people have to say. And as mentioned, even if the numbers ultimately say it could work in theory, and even if the politics get sorted out, there's still the immense practical engineering problem of simply building the fuel tanks at all, let alone making them even remotely safe from punctures in operation. These issues put the NSWR in the same category as drives that require the presence of a black hole or the like. Maybe possible in theory but utterly impractical to build.
