I am using a pump in the DW20 pack that seems to be OK - Its called "Pump" from Ranged Pump mod
Hmm, does it accept power from any geothermal generator so you kinda get a infinite loop of energy supply by the lava?
Eg. the geothermal generator gets its lava from the ender tank>pumps the lava into the ender tank>ender tank supplys both overworld and giving infinite loop to the pumps
Also, if this works I will need a chunk loader, BUT does the built in chunk loading work in Nether?
I mean the GUI you can open up and just click the chunk you want to claim, or is that not for chunk loading, just claiming?
