Electricity is supposedly planned for future updates in the form of generators, and people already use non-vehicles as ad-hoc appliances, so yeah. The problem would just be the machinery.
Speaking of which, would it be possible to create/move certain machinery for fortresses (like the trash compactor and, since we’re on the subject, a lathe)? It’d probably require a lot of skill and possibly a lot of materials, but hay. Nothing like your own lathe in your own fortress.
