Spacescifi

Oh...this could be still be untrodden territory for scifi. Consider....are they prepped for boiling cadavers and using them as propellant? No. Which means....the boiler they do have is too small for a cadaver, let alone two. Which means some poor guy or gal is going to have to 'disassemble' them...piece by piece. IN ZERO G! Messy and gross is an understatement. Do they have medical saws aboard? Hope so. Otherwise we are talking cutlery. Don't envy this person...at all. Probably will suffer from PTSD after. Even worse if they lack medical training and or the cadaver is opposite gender and they had a romantic relationship with them in the past or were developing one. Even if they were not, how do you explain to your significant other back home on Earth what you did to survive.? You don't....not easily probably. Also somehow the people responsible must transport the hot boiled soup of the deceased, likely by unbolting and transporting the boiler itself to a place to pour the contents into a spare propellant tank for miscellaneous propellants. Exactly. If stored you can do that. But when you run out? ISRU is your only option. The problem is how many different spare empty tanks do you need? There are more options than you can really put tankage space form If you are relying on LOX and LH then those are the only resources you hunt for. Since an LH tank as far as I know is not something you want to mix up with other propellants, and definitely not an LOX tank...because of possible combustion/explosive reactions. So there is a limit to tge variety and number of spare ISRU tanks you can realistically carry on any spaceship. One design I think could work well is an oblong vessel with an inflatable bladder at it's center of mass. Ideally it would find an icy comet or icy asteroid, extract as much water as possible and fill up the bladder balloon. So that you have an oblong vessel with a massive balloon in the center connecting both halves of the vessel, since it has more volume to hold propellant than the actual vessel's interior hull. Fat and ugly? Sure. Effective? Very if designed properly with the best materials for the job.

Hahaha! You may regret saying that. Because we are about to boldly go where probably no scifi has gone before. "Alright guys, I know you're sad about our two engineers dying from fixing the engine, but we owe our lives to them." "Shall we store the bodies for burial when get back to Earth?" "Do not throw away what you can still use. We are running low on propellant. We have already burned through half our orange juice and vodka reserves. I suggest we....boil them and use the liquid as extra propellant. That way we can save on our more precious LH propellant." "You're a sick man Cap." "Hey...I just want to go home and I know you do. Whatever it takes. It's either that or lower our chances and we all die anyway." So how much ISP and what kind of thrust or disassociation can we get out of a half liquid ton of milk, a half ton of orange juice, and 3 gallons of blood plus whatever is left of the cadavers that was boiled into mush and burned as propellant LOL?

SOME countries would be OK. Even the 'free' countries Especially when it becomes a cold war of sorts given the beyond human abilites they have everyone will want to have an edge.

Water is a good option....but remember just how complex this whole siituation is. 1. Big LH tank for NTR. 2. Multiple ISRU tanks for each different propellant you are likely to try and ISRU. Cannot just go around shoving any propellant we want in any tank. Ideally we could just use inflatable bladders as tanks to save on inertial mass resistance to enginet thrust.

I see your point, but legally it is just paying extra for super abilityl adopted children. Legally they would be citizens like any other. Illegal slavery does occur, but an Alpha does not consider anyone who enslaves them against their will their master anyway. Will escape at first or best opportunity to do so.

Yes they will, but only within thermal limts since those chemicals run hotter than cool hydrogen does. And LOX will probably eat up a reactor like a big guy eats a pizza solo. Some chemicals erode reactors bad...others not really.

Yes LOL? Uh huh...you could say the same about the hard wired human tendency to want to procreate even when it is not necessary. And yet I don't see people complaining en mass about that LOL. Nevermind the fact that is an individual choice whether one does or does not do that.

NTR spacecraft seem ideal for orbit to orbit and low gravity moon travel. Refueling? Tricky and challenging. Why? According to scott manley to get the highest ISP by running your reactor hot as you can without damaging it you need LH. Apparently higher atomic elements are more likely to MELT the reactor. To get LH you must travel to a source, and extract and cool the hydrogen gained into LH. If hydrogen is NOT available you run the chance of melting ordamaging your reactor from heat overload from using a denser atomic chemical...unless you go super slow....which has issues of it's own due to crew health. Seems to me one easy solution is to keep spare LOX in storage and use regularLH/LOX chemical rocketry or anu other chemical with LOX when you do ISRU and hydrogen is not reasily available to mine. So using known tech, any spacecraft exploring our home system will need BOTH nuclear and chemical rockets. NTR for orbit to orbit and hydrogen ISRU when available, and stored LOX to use for chemical rockets if hydrogen is not available. Best not to put all eggs in one basket I think. What do you know on this? Did I understand this right? Locations hydrogen is hard to come by: 1. The moon....we hope it has enough but it is limited. Mercury: I dunno. I think it may have low if any ice at all. Venus: Wouldbe easier to die trying to mine hydrogen here than to mine it. Places Hydrogen IS available in other than Earth: G Jupiter, Neptune. Uranus, icy comets and asteroids. Likely several outlying moons farther from sun.

Not exactly...since the Alpha form of slavery is by choice of the slave. It's a lifestyle choice. If they don't like a person to begin with they won't choose them as their master. It's more an individual matter than an economic one for Alphas. Which is a good deal different from what humans think of when they hear the word slavery.

I was not...but we both know any good transport can double as a weapon....which is why I don't want it TOO good. Just would take one ir a few programmed doomsday robot vessels to reach light hugger speed and collide with Earth with little options for stopping them and not much time either otherwise.

It's fiction....not reality. But for the fiction...oh yeah it's hard coded. Part of what makes them Alphas and not...us. And at best one might...persuade an Alpha with difficulty given their superiir intelligence? Brainwashing? Not likely. Would be a feat to pull off on an Alpha. Granted....one may call into question religious Alphas...but all an Alpha has to do is agree with something to actually support it....regardless of ethics or truth, false, right or wrong. Yet convincing them to change their mind? Difficult.

Why? Too overpowered otherwise. If anything can just high thrust indefinitely you can stick on disposable missiles and NOTHING will stop you but other missiles just like them. As matters are, that can happen still but it is less likely since thrust time is not unlimited. I am saying that the fuel pack IS also your propellant and power! This is a scifi drive, not a typical rocket, which is why refueling off natural resources is not an option. It actually emits no gas or plasma exhaust. Just scifi light rays that are strong carriers of magnetic force. The nozzles are polarized and are strongly repelled when the repulsive rays fly out, losing magnetice force with distance.

For what it's worth, Chris Roberts has been working on on an unreleased uncompleted space sim game for over a decade. Meanwhile Elon builds actual spaceships and flies them in less time LOL.

Cannot make an omelette without cracking eggs they say....

Yes.

It's not time window. It only starts ticking when you use it. Coasting saves it for later use.

Not enough boom juice...vessel could carry a lot more for personal use but safety regulations stipulate dropping them for future explorer vessels to utilize.

I don't think you understand. Do cats and dogs have problems with how they look naturally? Neither do these 'aliens'. Free will for them is ALMOST human. Except for certain behaviors and beliefs that are rather, hard coded. Alphas for example believe slavery....at least THEIR form of it is fine. Namely where THEY choose their master and the master is obligated to look after their welfare for life. Picky and stubborn as they are...it takes years before they settle on their personal master anyway LOL. Some races have quirky behavior in part derived from animals...by popular demand. The CEO never did order catgirls, although he did order a close substitute to appease demand. They lack tails or cat ears, but behaviorally they definitely have some cat traits mixed with human ones.

Not really. Car can take you or train to nearest airport overland.

Dock at seaports, don't fly overland.

How viable is a sea plane that uses closed cycle nuclear water propulsion? Since closed cycle nuclear is safe-ish, and if the plane goes down in the middle the ocean so what? Lot safer than over land. It be the kind of airplane Batman would like LOL. Theoretically it may be faster than a jet airliner for intercontinental travel, because it only has to refeuel using ocean water. The main challenge is landing safely everytime. I suppose it will be like a giant seaplane of sorts with huge wings.

Profit and glory. He is arguably no different than any other visionary CEO in that regard. To be remembered for doing what has never been done. For lack of eternity....to do something that will transcend beyond him. That is the kind of stuff mankind get up to when they are not scraping by with the basics of food, clothing and shelter. The irony is that Mars colonists as per the plan will be doing EXACTLY that.

Constant acceleration high thrust the whole way is too OP for me. Also seems too unrealistic or at least too easy.

It does not work on people....not well anyway. It does not work on people....not well anyway. And the CEO does not view the 'aliens' as deformities. He views them as improving...transcending what mankind is capable of. Granted there ARE niche humanoid races purely for profit motive, but the ones the CEO promotes the most are ones either specialize in increased intelligence, agility, strength, or endurance, etc. They can even make races that can live in zero g space habitat environments without issue, though they still need to breathe, eat, sleep and drink.

I presume you think the better way is to allow people to choose this option for their offspring rather than unilaterally choose to become the company 'gods' of several new humanoid species? As matters are, a baseline human cannot be modified at the same level as the 'aliens' are. That is why they start them off early in an exowomb from conception onward to modify them. It's more practical and possible at that stage than trying to modify a finished product . Of course the 'better way' won't allow for the same level of company consolidation of power either....
