There won't be much way to power a lot of tech, because even solar power is often ruined by the incense cloud coverage (although it has a better shot at working in the cities, particularly Kiichpan and Coatepec where they're less exposed), and there's next to nothing to use for parts save what people might've brought with them. If she can find a way to engineer things though, that can definitely happen. Especially if she starts teaching the locals, too. They're an industrious bunch.
