  1. I was wondering if it would be possible (and better) to use some xenon or krypton compound as oxidizer or "fluorinizer" for rockets. For example xenon hexafluoride, or xenon oxytetrafluoride, or nitrosonium octafluoroxenate, or... Noble gas - chalcogen/halogen bonds are weaker than chalcogen - halogen, interhalogen or "itself" bonds; so that reacting with a fuel should generate more energy (=more thrust and isp?) since less energy would be required to break the previous bond (or more energy would be produced from breaking that bond). However, there is the problem that xenon and krypton are (relatively) heavy atoms, so they could negatively affect the isp. What do you think?
  2. What about a liquid fluorine - solid lithium hydride hybrid rocket?
  3. Ionic propulsion is useful for making precise movements in space, and can be used to travel to other worlds through techniques that involve periapsis (I do not remember the name of these techniques very well). Ionic propulsion has a very high isp, but a low thrust (just like in real life). In general, the average life of a deposit of xenon is much higher than that of any other fuel for space exploration. However, there comes ionic propulsion becomes useless in many goals. It's just very slow, and the game does not allow you to speed up time (over x4) while the ship is propelling itself. Nor is it possible to program complex and automated orbital motions that would be very useful for ion propulsion drives. This mean that ionic propulsion is finally used for very few things due to its slowness and need the constant attention of the player. KSP should implement warp under acceleration (in space and over x4 speed) and programmed automated orbital movements, at least when using ionic engines.
  4. For planned parts... What about lithium fission rockets or saltwater lithium fission rockets? (sources: https://forum.nasaspaceflight.com/index.php?topic=39844.20 and https://www.physicsforums.com/threads/clean-lithium-fission-saltwater-rocket.863418/) And positron radioisotope rockets? (https://www.nextbigfuture.com/2018/05/positron-dynamics-antimatter-propulsion-drive-update-april-2018.html)
  5. I found an interesting idea about a propulsion system that would be based on the fission of lithium-6 (exothermic reaction that is only possible with high-energy neutrons). As I understood, it would use water or heavy water with dissolved lithium hydroxide. Such water would be irradiated with fast neutrons generated in a supercritical plutonium nuclear reactor, a non-aneutronic nuclear fusion reactor, or a spallation system. The water would be heated by the reactor like in a classic saltwater nuclear rocket, but the fission of lithium-6 would generate much more energy. This translates into an ISP higher than that of conventional chemical and nuclear rockets, and a pushing force superior to that of ionic rockets. The main problems are the neutron source (it must be big) and, in case of use a supercritical nuclear reactor, the risk of core meltdown (typical of nuclear rockets) or even a nuclear explosion. It could be interesting to see an addon based on this idea.

  6. Ammonia borane (H3NBH3) is a compound with properties analogous to ethane, but with a higher point of fusion. Basically ammonia borane is solid at room temperature and pressure, unlike ethane that is a gas. Ammonia borane has an special property: it will release hydrogen while is heating (being transformed to H2NBH2, next to HNBH) until degrade to nytrogen boride at 1000 "C. If ammonia borane isn't degraded to nytrogen boride, it can be recharged of hydrogen. This is a good thing, since a ammonia borane volume is able to store much more hydrogen than the same volume of liquid hydrogen. Then, it could be used for build light reusable rockets, as well as compact high hydrogen density cells of cars, and like hydrogen batteries for jet engines. Currently the ammonia borane is being studied for its possible application for hydrogen batteries of future, the main problem is the production of this substance, together logistical problems derived in the extraction and recharge of hydrogen gas from it.
  7. So I came back, and I bring an idea from two years ago, but improved: Omnidirectional wheels. In addition of other two new: Continuous tracks and Screw drives Omnidirectional wheels: Omnidirectional wheels are wheels and systems that gives the ability of move omnidirectionally without spin to the land vehicle. My idea is basically add these three types of wheel (and variants by company or size, of course): - Omni wheel (little). - Mecanum wheel (small and medium). - Liddiard wheel (medium and big). Omni wheel: Omni wheels are basically primitive omnidirectional wheels. They are common wheels with added little wheels to the edge, in perpendicular to the main wheels. These wheels would be slightly hard to use, possibly would need the use of action groups. However, with this you can make functional omnidirectional vehicles with octagonal, triangular, etc shapes. Mecanum wheels: This type of wheel is a multi-wheel that contains small wheels aligned 45º over the extreme of multi-wheel, and aligned 45º degrees over de radius of multi-wheel. How it works? Small wheels deviate the multi-wheels when these multi-wheels spin each in different direction, this causes a lateral or spin movement of vehicle, much more useful. These wheels would be easier to use than omni wheels, using like controls AWSD, and also Q and E for move to left and right without spin. Basically, vehicles with this type of wheels would have a better maneuverability and bigger left-right speed than the other two types, but it would have a big lack of friction. Liddiard wheels: Liddiard wheels are basically toroidal wheels which inside has rollers and tires has an special rolling system. This type of wheel move like common wheels, but its toroidal tires can spin from inside to outside for move right or left. These wheels, like mecanum wheels, use AWSDQE controls. Basically, vehicles with this type of wheels would have a big friction and traction, however the left-right speed is the lowest of the three types of omnidirectional wheels. Continuous tracks: This is the drive system of tanks and several types of tractors. This drive type would have sizes from small to big. additionally, these could have an special modular building (ie, you can adjust the length of the continous track, longer will cost more expensive and shorter cheaper, obviously). Screw drive: This would have an extremelly big friction, plus the ability of move left and right without spin. Controls are, again, AWSDQE. The problem of the screw drive is its big size and mass.

  8. KSP is realistic, and FTL is protorealistic. We simply don't know if such thing can exist really. And if FTL is impossible, KSP will stop of being realistic. Anyway KSP is based on actual and near future tech, so, FTL is very far. The thing that could be a good idea is to add different solar systems to choose at the start of the game (an red dwarf system, an blue supergiant system with tens and tens of planets, etc), but of course, it will not be possible to change of solar system of a game profile after start such game profile, and it will not be possible to move to others stelars systems.
  9. The idea of add liquid coolant is simple. The liquid coolant would be a new material storable in little tanks, with little amount needed (ie, little consumption). This material could be used in engines, intakes and heat shields to refrigerate these parts (that are overheat in high velocities in the atmosphere commonly). The use of this material could be automatic or programmed in action groups, also could add a little more isp to overheat engines, due that can be used like propellant when is used to refrigerate. Also could be used in thermal nuclear engines instead liquid fuel, the difference of functionality is minimal, with the only difference of that liquid coolant is more expensive but can prevent overheat.
  10. You must do "right-click" in the crew cabine (the head of rocket, were there is the kermans) when you are using the rocket or aircraft, so you will see several options, you must select the "crew report" option.
  11. This is may be a dummy question, but I do not know what mean "apha1" (for example) in controls of game and, so, I do not know how can use custom action groups, obviously. Please help. Thanks in advanced.
  12. Neil deGrasse Tyson concluded that the mjolnir would be make of neutron degenerated matter and have a weight of 300 billions of elephants...
  13. And the major part of hypothesis to unificate strong force and electroweak, suggest natural mechanisms to "violate" these conservation laws (better said, exchange these), related with the hypothetical proton decay. p+ → e+ + π e+ + e- → 2y π → 2y Strong force and electroweak unification implies that the barionic number can be exchanged with the leptonic number. The basis of think in proton decay is, if protons does not decays, these violate thermodynamic laws. https://en.wikipedia.org/wiki/Proton_decay
  14. Magnetic monopoles are present in lots of hypothesis (not only one), and in hypothesis should have stable subtypes. https://en.wikipedia.org/wiki/Magnetic_monopole
