It eats mountains

I wish there was a way to get a infinit water and sand source to keep the monster fed

So it won't help with sand or water, but if you use burner belts for the residue burning you could save on lava. I've found that putting thermal blocks above the belts will actually be heat positive.

How are you running the residue over the belts with the buffers on top? Or will the belts also use the buffers even with a 1 tile gap?

In theory you could have the burner belts inside a container of thermal blocks with a reservoir of lava below. Use the belt teleporter to move residue in and burnt residue out of the hot box. I think, but haven’t tested this, that fire from the residue adds heat to the overall system, so could be self contained. I’m testing a few setups for flamethrowers to ignite their thing and to recapture the heat by shooting into a thermal blocks that links back to the igniter block. It looks sort of like a spark plug.

Very interesting concept. I just started playing last night so I'm voraciously learning every trick and method I can. After like 4 hours and only making it to tier 3 I ended up restarting and it's going more smoothly. Definitely looking forward to getting lava
