Reactionless drives would be so nice.
Not only could you transport materials around, but you could make Venus spin in 24 hours in ~10^4 years using currenr Earth electricity output and a super-conducting emDrive -- I did the math a couple years ago.
- aeternum 6y agoThere's really plenty of reaction mass around though. Could probably get it done quicker by having a few large drone ships that harvest reaction mass from the planet or nearby asteroids.
- m4rtink 6y agoReactionless drives are indeed nice and really really dangerous - they make Earth shattering relativistic projectiles a bit too much easy to pull off. Pair one such drive with a nuclear reactor and have it fly away from the sun for a while and then back - it will hit ludicrous speed on the way back, likely a good fraction of C. And there is hardly anything that can be done to prevent that as it needs just energy to gain speed, not bulky inefficient reaction mass.
- pas 6y agoThere's really no substitute to mind-uploading when it comes to defense against kinetic stuff.
- m4rtink 6y agoYep - the ultimate solution fo many dangerous sitations - make the people in danger more robust or ideally effectively immportal. Solves a lot of issues & makes otherwise very complicated safety measures into much simpler ones.
