And this is why the pack on my private server makes the TE extruder take 60s and 4B of each liquid per obsidian block.....and people still prefer it.Yeah yeah, but scaling it to *billions* of blocks... With no power requirement. If there's a valid way to do it, do it that way. Using a reactor to make lava and power the obsidian maker would be valid... No point in crying over spilled obsidian now though.
