Question	—	How fast do we spin this for 'One g' Following on from this question. Question Context : Mars second moon Deimos has been converted into a generation ship. A considerable portion of its mass has been shaved off during the process & ejected backwards along its path by Railgun to help increase orbital velocity (if we need additional th...

Question	—	How many people can a sealed 3x1x1 km biome support? Question Context : Mars second moon Deimos has been converted into a generation ship. A considerable portion of its mass has been shaved off during the process & ejected backwards along its path by Railgun to help increase orbital velocity (if we need additional thrust to break orbit, perhaps nucle...

Question	—	If we dug a really big hole on Mars, how long would it last? How long will a 400 km wide 30 km deep pit (trench or crater) with a relatively shallow (for stability) gradient of slope of 20 degrees from the edge to the surface of the planets crust be expected to last on Mars before geological & climate processes close it. Rock plasticity under the weight & pre... (more)	—	about 5 years ago
Question	—	How much processing power would a real time Edited Reality headset need to render video in real time Imagine a VR headset with built in camera & AI with object recognition & photo editing software. The camera records the image. The AI is trained to pick out 'undesirable' images, objects, shapes & faces. Which it edits out & replaces with the correct / extrapolated background from earlier footage.... (more)	—	about 5 years ago
Question	—	The Hydrogen Dragons of Capella Signi Alpha The fossil record indicates they evolved far back in their ancestry from something not dissimilar in appearance to a lobe finned fish, but with an extra pair of bilaterally symmetrical fins, though they now look surprisingly similar to the appearance of the more serpentine mythological dragons of ear...

Question	—	How damaging would a major solar flare induced EMP event really be? With specific attention to national electricity power grids. Some pertinent details needed to answer the question might be. What parts of the power grid get damaged by such an event How do they get damaged How quickly & easily can damaged components be replaced What is the expected effect on nu...

Question	—	What's the oldest plausible frozen specimen for a Jurassic Park style story-line? We've found all sorts of interesting stuff in arctic ice & permafrost around the world. Bacteria & the like far older than the more media friendly mammoth specimens have been found, living bacteria has been found in ice cores as old as 420,000 years. Obviously I'm not thinking about living specimen... (more)	—	almost 6 years ago
Question	—	The Mighty Generation Ship Jupiter "The planet moves." Inspired by this link in a comment from Gryphon here, I also see the concept in this question. We've colonized the moons of Jupiter adjusted their orbits to our satisfaction (to avoid them being crisped by the BFR that comes next) & have suitable methods of adjusting them furthe...

Question	—	Ancient Roman Pneumatic tube Postal Service The Romans had pumps, aqueducts, water wheels (which were used to grind flour, saw wood & stone etc), valves & pipes (they are known to have used stone, clay, lead & copper for pipes). All the ingredients in fact for a pneumatic tube system for delivery of small packages. So, would an alternate pa... (more)	—	almost 6 years ago
Question	—	Is broadcast power suitable for recharging robots? The last time I checked ASIMO's battery pack only had enough juice for something like 30 minutes of continuous operation & then it has to plug in & recharge which isn't really that useful. I'd like my free range robots to have a little more up-time, somewhat less down-time & not have to worry so muc... (more)	—	almost 6 years ago
