That would make sense; no reason why you couldn't build a generator of some sort into your mobile base, or strap lights onto the outside.
I suppose it would give a more obvious use to the electric motors I've been finding recently. To build a makeshift generator to light your safehouses would be kind of cool, but you'd need plenty of batteries lying around to keep it running for a reasonable amount of time.
We've already got solar panels and electric engines for vehicles, as well as gasoline (and plasma) engines. No reason why we couldn't have generators using any of those sources that I can think of.
Yeah, but I've never found a single solar panel as of yet, and the electric motors have to get their energy from
something. Batteries, although they have much better uses, could be used as a substitute, but they'd only have to be an emergency energy source (i.e. if something destroys the solar panel(s) you
do have). Plus, the gasoline engines would be noisy and emit toxic fumes, and hydrogen/plasma packs are super rare.
