Background A McKendree cylinder is a spinning space habitat in the style of an O'Neill cylinder (below), but orders of magnitude larger. McKendree habitats are hundreds of kilometres in diameter a...
I've seen Which is easier to develop: a piston prop engine or a jet engine? and my own Effects of ~10atm pressure on engine design neither of which answers this. Would different atmospheric densit...
In my story Giants, humans, and a bunch of other fantasy races live along side each other and i'm curious as to what might be an effective mode of transportation for 10 foot tall Giants with Ancien...
When designing a flying car intended for congested city routes with slow traffic, should turn signals indicate all possible directions. In most sci-fi, I've seen designs that have no turn-signals o...
The universe is dying because it has exhausted nearly all of its resources. Humans became the last species in the universe because of their resilience and sheer willpower. And yet, humanity still...
I've heard there was no upper limit for the size and weight of a ground effect vehicle. In my world, the people there wanted to design a quick response aircraft carrier that could reach anywhere...
After reading this thread from a bit under a year and a half ago about the most cost-effective means of travel on Mars, where one of the answers mentions rail as the best option, I started wonderin...
Sulfur hexafluoride is pretty awesome. It is a gas six times denser than regular air, and thus you can actually make tinfoil "boats" float on it. It also makes your voice deep when you breathe it i...
I want to design a realistic interstellar spaceship that uses centrifugal force for only the crew quarters. But while looking up for designs I found the most common ones are the torus or ring desig...
How would a biological drop pod make it into the atmosphere and land safely? I have a race of aliens that use biological tools instead of technology. Their ships are living beings that can travel t...
So I have in mind a plot point in mind where my protagonist is elected to pilot a giant humanoid robot with flight capabilities - Kinda like a mobile suit from the Mobile Suit Gundam franchise. To ...
This is a bit of a continuation of my previous question, could a form of acoustic levitation be used as artificial gravity? In that question, I referenced how some scientists use acoustic levitat...
What kind of system using modern technology would be able to counter a railgun projectile on a vehicle (both land and sea)? Would a think slab of angled armour in the shape of "<" work to cover ...
I want to create a Mad-Max-esque post apocalyptic setting. Unfortunately after a bit of looking into this, there is one massive issue with the idea of lots of maniacs tearing across the barren lan...
Assumptions - atmospheric pressure is 3 atm, but partial pressure of oxygen is comparable to earth, the rest is mostly nitrogen. Planet is tidally locked and insignificantly heavier. (for simplicit...
The great venture capitalist Elian Minsk has decided to start an "autonomous" car driving service. But who needs complicated AI based systems when he can hire tech support workers in India to driv...
Take a planet with an atmosphere similar to Earth's but, say, 9-10x as dense. What is this going to mean for the performance and design of the heat engines that are so familiar to us? Higher oxygen...
In a world like ours in the 1980s, but which for whatever reason does not use any form of electricity. (Either it does not exist or batteries and generators etc have not been invented.) For purpos...
In my world, 500 years in the future, my population fits anti-gravity engines to salvaged boats as a form of transport. These transports fly close to the Earth's surface and are powered by a highly...
In this world, the vehicles are effectively re-engineered insects; enlarged bio-manufactured nervous systems used instead of engines; factory grown lightweight chassis / [wheels]. The fuel station ...
In this scenario, humanity has managed to colonise some of the solar system, including Mars, some of the moons of Saturn and Jupiter and some of the larger asteroids of the belt. In most places th...
In my story, humans have colonized both a high-G and a low-G world in the same star system. How would surface vehicles have to be designed differently for practicality and economy on each of those...
In my story a man who works in Military Intel gets early warning that a nuclear attack on his base is inbound. He abandons his post, grabs his wife and kid from on base housing, and books it out of...
I was looking into the Dobles of years past after watching videos of Jay Leno's Doble E-20 and was trying to imagine how one could make the steam car a viable competitor to EVs and obviously one of...
Context On my world, there is a lot of water: sea, oceans, ... There are also firm land and islands, so it's interesting to travel on the water. The problem is that there is NO wind at all, and lo...
Question I am currently trying to create a dramatic introduction for one of my characters, John Smith. The current iteration of the idea has him suddenly colliding with a solid wall on a motorbike...
I want to write a science fiction book on a planet mostly covered by ocean, but I also want to incorporate trains into my story. However, it seems that with advances in ship and plane technology, t...
A sandcrawler is is a tracked vehicle about 40 meters long, 20 meters tall, and 15 meters wide. It has a thick outer hull for protection from the elements. It has eight sets of tracks, four abreast...
I got pulled into 1885, just like Doc and Marty (Or I'm one of them, assuming I can get IP rights :)). I need to go back to the future, which means that I need to get my Ford Pinto time machine up ...
If a modern Day tank suddenly appears in 14th century Constantinople; in perfect condition, along with all the ammo, fuel, and components needed for it to run. How much of the technology in the tan...
So let's say I have a super cooling "battery" basically a brick that cools anything that touches one end of it to ~0k. Now, using handwavium I can thermally isolate it so that it doesn't just cool ...
I've been playing a lot of Deserts of Kharak lately, and I am wondering if landships depicted in game, which are essentially seagoing ships on tracks, would work in a Snowball Earth scenario. By Sn...
Tech level - comparable to contemporary; no fossil fuels, all fuel has to be produced synthetically, as simplest to produce (and store!!!) was selected methanol. Theoretically quite good - superio...
Let's imagine a race of Giants, with an average height three times that of a normal human being. Let's also imagine that these Giants are completely identical to humans, proportionately speaking......
I have a very specific aesthetic in mind for my science-fantasy setting, technology is largely pneumatipunk supplemented with weired phonotic devices;for "reason" there are few electrical devices i...
It's common knowledge that one of the things that makes stealth aircraft so stealthy is that the body is covered in a skin of special material that interferes with radar. Would it be theoretically...
