Trying to do experiments on non water maps like humungous is currently impossible. If I take a pump and fill up a liquid duplicator it works fine in the sea map, but if I save it and use it in another map it seemingly doesnt work, like it doesn't feed into the boiler-turbine-cooling tower loop at all and no power is generated. The save is literally just a liquid duplicator with water in it.

It is probably a bug, but since I really wanna experiment with smaller nuclear reactors for vehicles I would love a smaller variant of the condenser. Maybe liquid salt based coolant? Real life compact reactors are usually loaded with quite hot fuel and run on a primary liquid alkaline alloy (NaK or similar) loop with a secondary water based loop. There are other designs (thermocouple part, anyone?) like Radiothermals, like the SNAP that the US loaded on their spy sattelites and even brought a variant of to the moon.
