There's been a concept in my mind for quite some time now, which grew out of the question, "what would an education system for aspies look like?" My idea was that it would be a well stocked residential school - internet access in each, single, ensuite, dorm; dim soft lighting and dull colours for the sensory aspects, with a farm, library, dojo, workshop etc in the building(s). There would be kitchen facilities available for those wishing to make their own food, however there would be a canteen providing food (from the farm, worked by those interested in farming), cooked by those who's interest is in cooking. Independent learning, with tutoring available (very useful, if you just can't understand something), and in the case of the more practical subjects (farming, cooking, engineering etc), supervision to avoid deadly mistakes.
Then it occured to me that such an academy might be able to self-fund, by offering services - for example, it might have someone who is very, very good at fixing washing machines, by virtue of thst being where their interest lies. They might be unable to spin it into a career, due to the social aspects (note to self: possible business venture, acting as a gobetween for autistics and skimming a commision). The Academy would act as a gobetween for them, which would allow for extra money in the coffer.
People would remain in the halls until either (a) they get married or (b) they choose to move out. There would be a small village (initially; Rome was, as they say, never built in a day, even if Israel was) around the Academy, for those who don't/can't stay in halls any longer, but wish to remain within the small nation. Over time, this would expand into, hopefully, a fully-fledged city-state.
