Question High power microwave weapons for future spacecraft in somewhat hard sci-fi setting
In my somewhat hard sci-fi setting I'm thinking of using a high powered microwave weapon as the secondary armament of my ship to supplement the missiles it would carry. I was thinking it would be a pretty massive active electronically scanned phased array https://en.wikipedia.org/wiki/Activeelectro...

Question Human with super efficient metabolism
So I read recently this article as I was trying to design a sci fi alien race for my story and I found out that a human only has an efficiency of converting food to energy of about 25%. What would happen if somehow through a fluke of biology this alien race being very similar to humans had a metabol...

Question Non-aqueous eyes?
I am trying to create an organism that can survive in space for short periods, but I realized that I can't have its eyes be similar to those of most animals and humans because they would boil in space. Is there some sort of alternative for eyes that do not boil in space?

I have an idea for an extremely crackpot engine design for a future society I may incorporate into my story. What would happen is individual antihydrogen molecules injected into the center of carbon fullerene molecules using the combined electron clouds of the atoms to repel the antimatter into the...

Question Regenerating Fuel Cell
I'm working on a powered exoskeleton design for my universe and I had an idea about how to power it. It works in this cycle: Water enters an electrolyzer powered by a massive betavoltaic battery and is split into hydrogen and oxygen. The hydrogen and oxygen are run through the fuel cell to create...

What effect would this have on the development of modern society? Background: This would take place in a society that had...

Question Warp drives without exotic matter?
Taking into account all of the developments in the alcubierre warp drive theory including the new calculations by Harold White. Are their any plausible/theoretical ways to generate a warp bubble without negative energy or exotic matter? If this is not possible are there any theoretical ways to create...

Question tachyonic FTL travel?
Suppose you had a device with the ability to temporarily give your ship tachyonic properties. Would this allow for FTL? How would it affect warfare in a sci fi universe? The reason I am asking this question is because FTL seems mostly based on wormholes, foldspace, etc. and to me those don't have th...
