In a near-future world we have stopped directly fueling private, public, and mass transit and we have migrated to a hydrogen economy as the standard energy carrier. Consider the following factors:...
In the year 2099 A.D, humans made a major discovery. There is a rich source of fossil fuel buried beneath layers of Martian soil. It is estimated that the coal deposit that was discovered could fil...
What would make a good propulsion source for small engines and manouvering thrusters for spacecraft vehicles on Europa (moon of Jupiter), both for near-surface operations (vacuum) and in caves bene...
As in the title. We have the modern periodic table: In a potential near (or far) future setting humanity discovers a new element which serves as the basis for a cleaner, higher energy density...
I'm designing a small two-person spaceship for use in battles in space. It is set around the year 2100. It would be around the size of a tank (approx. 50 tons). It would need to be fast and easy ...
I have a potential sub-plot in a story that takes place in the not too distant future where most of the world's fossil fuels are exhausted or contaminated (war reasons more than environmental) and ...
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...
The Aurora company has unveiled the new Interplanetary Airliner (usually simplified to space shuttle) offering both affordable and comfortable space travel to the middle and upper classes of the He...
How would one go about repurposing a small cargo ship, no more than 50,000 tons, to run on an alternative fuel source/propulsion other than oil? And what alternative source would work best for prop...
I'm designing an alien race that hasn't developed electricity yet. Now, one thing about their species is that they haven't discovered fossil fuels on their planet to use, like coal, oil, etc. (The ...
I am designing an alternate world where the meteorite that caused the massive dinosaurs extinction never hit Earth. I am stuck in one point: If the massive deaths of the dinosaurs worldwide never h...
Consider a post-Apocalyptic society of collective farmers that has access to a waning supply of modern farm supplies, a small, independent power grid, and a enough knowledge to keep themselves fed ...
Would a starship that was propelled by magnetic monopoles fly faster and longer than ion engines (assuming magnetic monopoles exist) of course.
A civilization is very good at bio-engineering, and I was wondering if there was any kind of chemical an organism could produce which would produce viable rocket fuel. It has to do a of couple of ...
Although the fossil fuel coal had been used as a fuel since 1,000 B.C., it wasn't until the arrival of the Industrial Revolution from the mid-1700s through the 1800s that coal began to replace b...
Planet - habitable, tidally locked planet orbitting red dwarf. Aim: a realistic answer (neither involving handwavium nor aliens that used it all) why a virgin planet that already experienced a wh...
On Earth in 2017, finding oil or coal deposits is a tall order. However, consider a science fiction scenario where we find a habitable planet that hasn't hosted an intelligent species in at least a...
I'm not talking about a single alien civilization that is stranded on earth, I'm talking about multiple civilizations that will cause major overpopulation on earth. So this means that the civiliza...
My galaxy exploring ship is powered by a fusion reactor (back up with some solar panels but they spend a long time between stars). We know that stars are powered by fusion too, so they have all the...
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...
