Maybe I have temporary energy shortage in one dome, due to unforeseen cirumstances, and surplus in another. Would be helping if there would be mobile, fuel powered power stations (maybe transport some fuel with them as well), and a mobile power storage solution with limited output and storage. Maybe rover based, maybe not.

I could also have usage for a mobile sensor tower kit (amplification should be much less than the tower, but still very notable - maybe only the sector it is in plus direct neighboring sectors). Something flying would also be handy, sometimes you can't get up that mountain.
