These people inhabit an underwater city. In the city there are pools that connect the dry habitat with the outside ocean, this of course mean that the habitat is unpressurized and therefore the in...
Guests of this large space station enjoy Earth-like gravity (80-90% minimum). How? Well the space station is so massive it has its own gravity. The disk shaped "core" is made with ultradense mater...
In this world a secret society "farms" people with desired features (personality appearances etc.). They have ectogenesis of course; but they can't afford personnel to take care of the "products" u...
I want to build a seastead in international waters that starts small. It has to be in the Atlantic, preferably in the northern hemisphere close to either the american or european continent. Due t...
I am building a city in the sky; it floats thanks to hot air balloons and hydrogen. The main issue I have is how to make it grow, as this is not some kind of giant structure to start, it is a small...
An artificial endocrine gland is cultured in the lab and is to be inserted in a person. This gland functions by secreting special substances in the blood stream. It needs to be placed in a positi...
Some areas of the evil meant lair are not for the eyes of the average minion. There is only one way in and out of this area, there is no door blocking the way, but a lava waterfall pouring from the...
My human civilization is facing (much like us) the threat of anthropogenic climate change. For whatever reasons, they are unwilling to take action by reducing the use of fossil fuels and refuse to ...
Using only existing technologies, can we shoot 4-5 kg bullets into a stable, specific Low Earth Orbit (at least 1000 km)? The bullets don't contain "hardware" such as electronics, so acceleration ...
"Your children will be born in a world of two suns. They will never know a sky without them. You can tell them that you remember when there was a pitch black sky with no bright star, and people fea...
My space colonies are mainly located onto large, partialy terraformed moons in our solar system. They still travel using rockets but due to their vessels' large size they need very powerful propuls...
A K2+ civilization wants to build a fission star, a huge mass of fissile material which doesn't collapse due to the radiation emitted by its fission decay. I know there are reactors like the aqueou...
I have a super luxury space hotel. It has artificial gravity in the living and shopping area and 0g in some parts of the recreational area. There is a 0g pool available for the guests. I want it ...
These settlers live on a planet, which surface temperature and pressure are compatible with human life. However humans cannot breath its atmosphere. The gas in the atmosphere is not necessarily tox...
This creature is a waterdweller that somewhat resemble a fish. It lives in the retreating oceans of a planet orbiting a star that is reaching its red giant stage. The planet is now experiencing ver...
Imagine a SupraWorld being built around a gas giant like Jupiter. To have a 1g gravity on the surface the resulting SupraWorld would have to be less than twice the radius of the giant (my calculati...
Venus is being paraterraformed with floating cities. Mechanical machines collect material from the surface and send it floating at an altitude of about 50 Km where conditions are more Earth-like. H...
I am already aware of the concept of the fusion torch. But I would like to consider other solutions for separation of raw materials that can be automated but are less "extreme" and closer to curr...
My space colonists have found a home in the ring system of a (maybe chthonian) gas giant. The rings are based on Saturn's in terms of appearance, but can they be made of gases or liquid (maybe drop...
