  1. For some reason the thermal electric generator amasses 10,000 tons instead of the usual 6. This was after I redownloaded the mod. Edit: Despite having set up that produces enormous amounts of power (180MW) the All-In-One ISRU claims that the power levels are insufficient, and refuses to operate.
  2. It probably is a bug, I'll try reinstalling KSP-I later and see what happens.
  3. I (somewhat belatedly) finished writing up the chapter for Moho—since these tend to require a fairly extensive amount of research, they take a long time to write. I'll start working on the graphics/screenshots for the chapter, after which i can post the chapter!
  4. If we consider raw resources that would be exported, I think Mercury, the Moon, and just maybe the Gas giants might see Helium-3 mines as a profitable venture, if nuclear pulse propulsion becomes a viable form of propulsion. Mercury would probably be a major center for mining metals, which would likely be manufactured into various products.
  5. It's also possible to establish colonies at the poles, where water ice could exist (though obviously not portrayed). The thing about mining colonies on Jool is that the Delta-V required to reach orbit is pretty high, so that the products getting sent up into space should probably be well worth the cost (Helium-3, perhaps?) to be profitable.
  6. Currently I have a few sections for the next episode (Colonizing Moho), "Why Settle Moho?", Issues, Advantages, and Colony Design. I'd like some more ideas for these colonies, since I'd definitely want to have a comprehensive look at a future Kerbol System.
  7. A backwards planet? There's certainly more than just one meaning there!
  8. It doesn't seem to have an option for that...
  9. I've been working on the "Colonizing Moho" chapter, and perhaps what I wonder about most is what a Moho colony would export to other colonies. There's probably metal to be found, as well as some Helium-3, but this could probably be found on other worlds as well. Solar power is plentiful, but the beamed power ships I discussed earlier would probably make this somewhat redundant. Instead, the resource should probably be difficult to find anywhere else, and in return Moho could get something else in return. From my research so far, manufactured goods made using the beamed power/solar from the sun is the best I can find.
  10. How do you extract Helium-3 from the solar wind collector/regolith?
  11. CHAPTER VI: Beamed Power "25 GW of Power!"-Kerbol Electric A Quick Overview For the last of the chapters on propulsion (for now), we’ll explore the idea of wirelessly transmitting power to give ships energy without any need for on board reactors. The power source could be many things, but I’ll mainly cover fusion and solar as the main sources. Why Beamed Power? By having power beamed from a remote source, there is no need for bulky reactors, with only the receiver necessary. While the receiver can be quite heavy, it can generate more power for its weight than the onboard reactor. A large freighter with a receiver—it could get a lot of electricity, but it crashed because the receiver wasn't pointed at a relay/transmitter... Disadvantages It would be initially quite expensive to set up a network of giant power generators and relays so that power is available from any direction. Additionally, beamed power also increase the dependence of ships on just a few stations, causing a disaster if a station was knocked offline or destroyed. A Simple Tutorial I had a bit of a hard time figuring out the whole thing, which is why I decided to make a very short tutorial on setting up a beamed power transmitter. First Get your power source, which in this case is a fusion reactor, and then add the necessary electric generators to produce power. Second Next, attach a beam generator, in this case a gyrotron, which is needed for the operation of most of the transmitters. Third Add the transmitter, which is what will broadcast the power to all the ships, as well as radiators (especially for the reactors, which produce a lot of heat). Fourth Send it into space (somehow), and enable the transmitter function on the antenna. Receivers are simple—just attach them and enable the receiver function. While I didn't seriously test relays, they will be necessary to provide full coverage of the sky, allowing a ship to be able to fire its thrusters in any direction. Testing Fusion Fusion is an excellent power source, as it can be used anywhere in the Kerbol System, as it is mostly independent. At the most extreme size, the Stellerator reactor can produce 17 gigawatts! Unfortunately, such giant reactors require enormous radiators (unless you use the stock ones, which are strangely overpowered). Worse, the reactor has a limited supply of Deuterium, which runs out extremely quickly—mere minutes. Lithium-6 cycle fusion used a fuel that the reactor had a lot of, but the power yield was low. I also tested the Antimatter-initiated reactor, which outputs the same (with a smaller size) but uses Antimatter and Helium-3, both of which are rare and expensive, though Joolians may be able to capture large amounts of antimatter (in KSP-I, a stronger magnetic field results in more antimatter, and Jool certainly has a very powerful one). Testing Solar At very close distances from the sun, the amount of power that can be caught by solar panels is incredibly high. In KSP Interstellar, the largest receiver part available is a solar panel—one that can be tweakscaled to over a kilometer wide. The setup can easily generate over 25 GW of power, which is the largest I could get the biggest transmitter part to send. A major issue of using solar power as a beamed power platform is that these projects have to be built in the extreme heat of the sun, where the ships themselves can get hot enough to overheat. Additionally, their range is mostly limited to within Jool’s orbit, since the energy captured steadily decreases as one gets farther away from the power source, which is limited to right near Kerbol. Identical to the ship seen at Moho, this ship could get 10 MW at Jool—not full capacity for it's engine, but still decent Verdict Beamed power would be a major part of a futuristic setting, as they would allow massive amounts of power to be directed to electrical engines, which might reduce the effects of extremely low thrust, as the engines would receive their full fix of power. The construction of giant power plants would be a massive, expensive undertaking, but despite the disadvantages, it would generally be worth it. End of Chapter VI Thanks for Reading! I've got two ideas for next chapter: Either use this chapter to transition to talking about methods of electricity generation (solar, fusion, fission, etc...) or begin a new set on colonizing the Kerbol System.
  12. A most ridiculous ballad of Ike encounters I happened to get! I also got this shot in the same mission.
  13. CHAPTER V: Mixing Propulsion Systems "Mix and match, we've got 'em all!"-Kerbodyne In the earlier chapters, I’ve assumed that there is only one system of propulsion on board, and now is the time to address this. There are several reasons for using multiple systems, of which I’ll start with… The Primary Propulsion Source is Dangerous! While the Orion drive has the excellent trait of effectively being a low-end torchship, the ship happens to use nuclear bombs for this process, and they have a general tendency to blow up things in the general vicinity. Additionally, the immense thrust can often be overwhelming for small course corrections, where one may end up being even more off-course than when the burn started. There are several problems to finding a supplementary propulsion system, beginning with the fact that the ships that utilize the Orion drive are almost always gigantic super-heavy vessels, which means that the system will be gigantic. It will also weigh down the ship, as another fuel is required (though the Orion drive will hardly notice). A ring of fire surrounds the Orion Drive... This concept has manifested in a super-heavy ship carrying 1,200 tons of Xenon, and almost 1000 tons of Methane, with a literal ring of nuclear lightbulbs. Perhaps it is slightly extreme, as the acceleration reaches 8 m/s2. The nuclear lightbulbs themselves have 6,215 M/s of Delta-V. In general, this is likely overkill, but it shows that such a system can work. Similarly, the VISTA engine is deadly to all within a certain area. The Closed Cycle Gas Core engine also rectifies that issue! Since both of the systems use the same fuel, it doesn’t require another fuel tank. The Nuclear Lightbulb can also be used as a boost to the VISTA rocket, whose thrust isn’t too high. The Main Propulsion System Has Terrible Thrust! A major problem with propulsion such as the MPD or the VASIMIR is that they have excellent ISP, but their thrust is quite poor, a big issue when encountering a small gravity well at high speed, since it can lead to unwanted orbits as the spacecraft achieves orbit far after periapsis. This can be fixed by having a high thrust propulsion system. As long as it doesn't smash into Ike... One example I tested was by combining the Thermal Launch Nozzle and the MPD aboard the small-size ship. I used the MPD to accelerate out of Kerbin, and also on approach, but near periapsis I throttled up the TLN as additional thrust. It worked quite well, getting to Duna in 90 days (it is stuck in an elliptical orbit, though I’m sure a space tug can fix that). I also took scaled the concept up at a heavy-size ship, which reached Ike in 112 days with plenty of fuel still left. The Thermal Launch Nozzle was quite vital to a successful orbit insertion, as it provided a good kick, enough to send it on an intercept with Ike. End of Chapter V Thanks for Reading! Next Time: Beamed Power
  14. As you'll find in the next episode, that's the reason I've added Nuclear lightbulbs!
  15. Although the fallout would still be less than that of an Open Cycle Gas Core, where radioactive materials are definitely in the exhaust. Of course, if a serious accident ever took place, there would probably be a fair amount of fallout...
