I'm working on a computer program which generates realistic planets for worldbuilding purposes. I've run into an issue with calculating my planets heat loss. While radiogenic and tidal heat generat...
So I'm pretty new to chemistry and all this, but my world involves superpowers, which of course involves immense energy to have the characters use these powers. However, I want to stay consistent w...
My jet-propelled squid uses a scavenged shell for its pulse jet deflagration chamber, I am trying to determine how often he'll have to replace it. Including the shell it's a 5 kg animal using a ...
How do I calculate the thickness of the upper ice layer on cold ocean worlds like Europa, Enceladus, and Ganymede? I'm asking this for a programm I'm currently writing. The given/known quantities ...
I am trying to find a solution for a specific subset of the Stealth in Space Problem: dealing with waste heat without tipping off properly positioned observers. This question is scoped specifically...
The larger an animal, the harder it is to cool down. Ignoring the problem of bone/muscle strength vs size/weight and saying an animal could get to outlandish sizes, would a second cardiovascular sy...
In Larry Niven's Ringworld, the Outsiders lie with one half of their body in the shade and one half of their body in direct sunlight and use the temperature difference to generate energy. Would thi...
I have an idea for an energy source for a colony on a cold world with not enough solar power. Is my idea workable, or is it debunked as perpetual motion machine? Here is the set-up and my plan: Sc...
Water, as is, with its physical and chemical properties, is the base of any living being on Earth. Water has a rather high specific heat capacity of 4.184 J/gC, which in itself has a great effect ...
Backstory You won't believe it, but I'll tell you anyway. I'm a Level 61 wizard. If you think about it, wands aren't all that hard to use. Point, invoke, joyfully watch your enemy burn in the f...
Fire is certainly high up on the top ten list of mankinds most useful inventions. It allows for a more efficient utilisation of nutriants, is the basis of chemistry and the material sciences, allow...
Cooling in space is a well known difficulty. There are many unpleasant consequences like no stealth in space, difficult space battles which turn into a short wars of attrition (because you have to ...
You are the leader of a far-future civilization - human or otherwise - that has endured for trillions of years doing whatever far-future civilizations do. You've surrounded stars with Matrioshka br...
