At the moment the only use for the Space elevator is getting Tier Upgrades, which is a bit boring after a while and you only get to see the flashy effects a few times.
So i was wondering if we could maybe get something like "Infinite delivery". The idea is to put the SE on an automated timer after which it delivers all the rescources pumped into it into orbit. Maybe also ad some arbitrary value to the items so we can see our "gross-profit" skyrocket =)
This could also add an entire research tree for the SE with things like: energy efficency, cargo capacity or delivery frequency. There would also be the added bonus that the belts would keep moving, and who doesnt like to see their factory moving ^^
