I actually really like this idea.

Choose some reasonably good llm model + corpus of data to enhance the generation (e.g. wikipedia).

Package it in a long-lasting battery, rough device. Think of a tablet/laptop you would take deep into the desert for a multi-week trip.

A solar panel would be capable of charging a laptop. Perhaps one of those could be ruggedized along with the package.
