So I'm mulling over the idea of Atlantis staying in the Milky Way and considering the idea of the city relocating to a planet like P4X-351 and tying into the planet core for power in the same manner as with the Mobile Drilling Platform on Lantea.
This seems like a feasible solution for Earth's dilemma with dialing Destiny. Granted planets like P4X-351 are extremely rare, if they were able to find one it seems like it'd be a good solution. They'd have a great outpost to form a supply line to Destiny with and since McKay has come up with a means to minimize the risks involved with using the core as a power source there wouldn't be much risk with using Atlantis for this purpose. Worst case scenario they move the city to a safe distance if the circumstances turn grim, right?
One thing I was thinking about, if they're using a power source as abundant as a Naquadria core, do you think theoretically they could power the shield to encompass the planet in the event of an attack to prevent the core from destabilizing? In the episode "Echoes" its shown that the Ancients were apparently able to partially shield Lantea from the Coronal Mass Ejection just with their ZPM's. It seems possible they could shield a whole planet if they were using a Naquadria core.
What do you think?
