Use Ring Gates to mine gasses from gas giant atmospheres. The ring gates themselves are hung from immovable rods to keep them at a constant altitude from the crushing interior. Up to 100 lb of gas may be harvested per gate per day, therefore an entire array of gates is often deployed, all mounted on an immovable rod. One brave soul is assigned to the collector in order to activate the rod at the desired altitude, to bring the array back out of the gravity well when needed, and to monitor the intake for possible problems (such as native windswept fauna getting caught by the array).
Or course it all needs the people at the table to buy into it, but:
Continual Light/Flame/Darkness on an object at the bottom of a tube for a directional 'flash(light/dark)'
Firetrap in the same location with a sturdy tube.
Eversmoking Bottle to power machinery.
To show what I mean, the Ring Gates use the term 'put through', which might argue that unattended use will not work. There's also the 100-lb/day limit, which begs the question of what happens to the guy trying to put his 10-lb head through a gate after we've sent 19 5-lb metal ingots through. Asking where the 20th is, you see...
But if the table is in agreement, having the orbital-launch shuttle leave everyday PRECISELY on time as the one hundred pairs of ring gates under it all recharge at once, providing ten thousand pounds of high-pressure gas to the underside of the launch platform...
