SciFi applications
geoengineering
Earthquake controlled tension release cables (& why its probably a bad idea). A very dense net of tension cables would be needed in critical zones replacing much of the lithospheres structure (that must be dumped -prefferably in a structurally preserved way - at a supersurface location). Controlled release of a sudden ride in tension could avoid earthquakes while simultaneously providing immense amounts of energy. But if this is not sufficiently undestood this unnatural slow relaxations might lead to very unpleasant consequences. [to investigate: how woud one handle shearing on a wavy fracture "plane"]
disposal of radioactive waste into outer earth core (the well to hell)
APM and nuclear technology If it really stays there it will really stay there for the immense amount of time it takes to decay. If not we have made ourselves a radioactive volcano. Also radioactive waste might become valuable when Transmutation will be started. Doing Transmutation and all highly radioactive technology remote controlled right at these depths might be a good idea. Heating up the earth massively from the inside sounds like a bad idea.
earth core probes (very speculative!)
Forget about all those ridiculous things you've seen in SciFi a real probe would need to
- heat its outer shell of replaceable scales out of refractory material above the surrounding temperature to cool the internal space
- be nuclear fission powered
- be pretty big such that it has a low surface and big volume
- be very compact and densely built without macroscopic voids to withstand the pressure
- use materials that do not change their crystal structure under pressure (e.g. encapsulated water would collaps in volume)
- probably be rather slow too drill and digg its big volume through a hot viscous liquid (fast sharp cube cutting might not work))
- probably be capable of filtering material to regenerate its refractory shell
- use neutrinos for communication (very speculative)
