How can a ghostly being who can't be remembered for longer than 60 seconds secure access to electricity?

People remember account numbers: She's not in as bad of a place as you might think. semi-normal life (and the electricity she needs) is not so far away. Just because you can't remember meeting ...

How would electronics develop without petroleum/plastic? Particularly computers?

Simple answer: you'd make plastic. Thing is, whilst oil makes life easier when it comes to making useful petrochemicals, you can do pretty much all of the same things from coal once you've worked out ...

Could an EMP be generated from a server room with enough power to disable a bomb?

Semiconductor foundries are a thing of the past. Rebuild the computer industry if you can

Much Smaller Wafers and Much Larger Chips Smaller wafers require smaller foundries, which should be more survivable. This will drive the foundries to older tech, so the transistors will be larger. ...

Could an EMP be generated from a server room with enough power to disable a bomb?

An EMP affects only electronic circuits. Though ESD is an example of EMP, it won't have any disabling effect on an explosive, because the explosive acts only following chemical paths. On the contrary, ...

What considerations would have to be made for a spacecraft with minimal-to-no digital computers on board?

Electronics isn't the only way to do digital computation, you know. Fluidics is a particularly robust alternative, though not necessarily very fast or compact... clock speeds might only be in kHz at ...

Could an EMP be generated from a server room with enough power to disable a bomb?

Is the EMP necessary? There seems to be much easier ways to do this. Not to mention, the pulse from an EMP might induce a current on the dead-man's switch's wires that looks like the switch was ...
