Housecleaning in Zero-G Think through the amount of body hair and skin flakes a human sheds each week. On Earth, you take a vacuum cleaner or a mop. Still, fluff collects in hard-to-reach places. No big deal, really. The combination of zero-g and artificial life support systems makes fluff a greater problem in space. The solution? Almost-full-body clothing ...

Port Talbot Steelworks If you take the place over and keep the steelworks running the government will practically pay you to have your HQ there. Nobody will notice any heavy industrial equipment coming and going, nor any weird noises you might make. Your power supply is unlimited, I doubt you'd cause a spike in standard consumption no matter what you do. ...

Private ranches. Here are the ten biggest ranches in Texas. Ranging from King Ranch (911,215 acres) to Jones Ranch (255,000 acres). There are also large ranches in Oregon, Wyoming, etc. Every once in a while, these are up for sale, like the 510,000 acre Waggoner Ranch right now recently sold. Some of these even have their own electrical systems, solar and ...

witchcraft in this world is practiced openly by witches is exclusively female & Mana is continuously produced by the body in order to keep a person alive and functional. Males can't use magic therefore they can't spend the mana their bodies produce. This results in more mana stored in the organs that can be transferred to the witch. Females are ...

Spacesuits are compulsory The human body is ill suited for leaving the confines of Earth. Spacesuits serve a variety of necessary functions in order for humans to operate in space like temperature regulation, providing an air supply, protection from solar radiation, etc. Those living or travelling in space long term have to be prepared to enter hard vacuum ...

1 - We're icky There is a hygienic dimension to clothing. As mammals, especially placental mammals, we're always secreting and shedding something -- sweat, oil, hair, dead skin, and many other substances that are unnecessary and inadvisable to list. The areas we cover up are notorious for making right messes, and even the more acceptable areas may be ...

There are some great technical and political reasons laid out in existing answers, but there's also a very human answer which has been overlooked: They're creepy. It's the uncanny valley writ large - they're very human-like, but they're not really human. Not like us. That makes most people very uncomfortable, even afraid. And they're substantially more ...

The Mesoamerican ballgame was played by the Mayans in pre-Columbian Mexico and Central America, and ended in human sacrifice. Last year, when I was visiting a site containing an ancient ballcourt, the guide, a Mayan himself, told us that the team captain would be decapitated at the end of the game. He then explained that it was the captain of the winning ...

Contagious infection is the most likely reason such a belief/ fear would arise. Even if the plague was a long time ago, these stories are pervasive and would be passed down through the generations (think of all the superstitions humans held for thousands of years prior to the advent of modern science). A fear of illness from the dead bodies that has become ...

A similar system was used in the spartan agoge Boys were intentionally underfed to encourage them to steal food for themselves; however, they were severely punished if caught. This was part of the highly regarded educational system in Sparta Education in the agoge served as a great equalizer in Sparta. Any male who did not successfully pass through ...

A fictitious (not fantasty) story is set in a third-world country sometime during the 70s or 80s. The country operates similarly to any semi-developed country in central or south America. The countryside is barely developed, with maybe some token schooling. In the cities there is some technology, like airplanes and cars. The country has an armed police force ...

Eugenics + Poverty It actually happened. If you feel like hating humanity you can look up the practise of forced sterilization, which was quite widespread even 40 years ago. And you still see genocides in 3rd world countries of undesirables, it is not a far stretch to connect autism with undesirables. All you need is a tiny bit of propaganda in a ...

Hiding in plain sight Others have mentioned hiding in plain sight by placing your HQ below a legit factory or office building. This is a good idea, in that no one will notice your power and water consumption. But there are problems with these "plain sight" locations. For example, most cities require permits to alter the floor plans of the building. These ...

It just takes one disaster. Early on when the Caspar technology was still new and people hadn't figured out the quirks yet, a Caspar unit was put into a new ship without the proper therapy and retraining. They went crazy, crashed their ship into a population center and killed thousands of innocent people. Panic ensued. People learned that the Caspars can ...

Renewed poisoning Or another way of saying Mutually Assured Destruction. What the ritual does is both members of the couple personally poison a bottle of wine at the start of the ritual with a secret poison on their choosing. At the ritual, each partner drinks the other's poisoned wine. Unfortunately, there's no poison that is really long-term enough for a ...

Personally I see this as the wrong way around. Courtship isn't about trust. It's about proving yourself. Personally both sides should be trying to quietly kill the other because if the other isn't skilled enough to avoid assassination attempts, they aren't worthy to marry. What kind of parent would they be if they missed a simple poison in their wine? ...

Law Enforcement is — generally speaking — fulfilling the following needs: Protection. Hindering people from acting unlawfully. Prevention. Making people not want to or need to act unlawfully. Retribution. Exacting revenge on people that have acted unlawfully. Rehabilitation. Giving treatment to people so that they will not act unlawfully again. Reparation....

It is Difficult Mind-links may take a lot of energy and effort to maintain or establish. Maybe a mind link requires a large amount of energy, requiring those with the mind-link to consume a lot more food to maintain it. We're talking about at least another meal's worth of food. It is Uncomfortable Mind-links are dangerous, because such direct ...

Your description of mana usage looks a lot like organ donation. Organ donation is a very sensitive topic in the real world. People are very touchy about their flesh even after they'll never need it anymore. Some find the prospect of giving or receiving gross. Some have religious views that see it as a grave sin. Some think that allowing it freely would ...

Coming from a young marriage, a religion that places great emphasis on family life, and a wonderful TED talk, I believe that the evidence for monogamy and marriage may be strengthened with longer life spans. Life-long, monogamous marriages are based off of several principles, including forgiveness, humility, service, and acceptance. Such successful unions ...

The NGO could auction off the rights themselves to the highest bidder once the restraining order terms are violated. There are likely people who would pay to be able to hunt a human legally, especially if there are no limits on how it's done, assuming that only the abuser is hurt. Another source of income is trophies and footage. Once again there are likely ...

This can and does happen in the world now. Boarding schools and other exclusive private schools are for the children of families with money to send them. You will wind up with old money, new money, and anyone else as long as their families have money to send them to this school. Scions of old and established wealthy families. Children of nouveaux riche ...

What will happen in reality The first emperor is ailing. The five families, the Alphaei, Betii, Gammae, Deltae and Epsilones, make ready to cope with his impending death. Outwardly, each family is preparing a designated heir to compete in the imperial trials; the Betii are the only family foolish enough to put forward a heir of their own blood risking his ...

Just buy an office building right in the center of a large city. Put your secret stuff in the basement while you put a legitimate business on top. As long as your front business stays clear of any suspicious activity, you will never have any thorough inspections by law enforcement. Even workplace safety inspections will focus on the rooms where the official ...

There is only one "shield" (or "firewall" in more modern parlance) between the telepaths. Once a person acknowledges a ping and forms a connection, both parties have unlimited read-access to each other's knowledge, memories, emotions and even the current input from their senses. That access ends as soon as the connection is severed, but while it is ...

I feel I should add as a disclaimer that I have moral objections to much of this answer - however morality aside it is a practical solution. Eugenics. Should a pairing produce an undesirable child, sterilize it. (Back in the day they would often just kill the child, sterilization achieves the same result genetically speaking though). Should the same ...

Minor nobility Maintaining a bloodline with a limited pool is going to be tough. The trick is to expand the pool without corrupting the main bloodline. What we're going to do here is to redefine the "demigod" to be more like a breed of dog. It's a new breed if it's breeding true for 3-7 generations (depending who you ask). To expand the base pool we're ...
