I'm trying to create an obsidian factory. How do you manage to get LOADS of lava? 50 buckets?
The idea is having lava on the right side, and water on the left side. I use the lava pool to fill up one bucket, and place the bucket in the middle of the bottom "tunnel". I break that one block (clay) and the water pours down onto the lava.
Basically this: http://www.youtube.com/watch?v=NGj3-0r8D8Q
But this will take LOADS of lava.
EDIT: I've just realised I can't mind obsidian. I need a nightmare pickaxe. Goddammit. Still, can someone help me out?
Why bother with all that, just dig a tunnel to hell and take any water you find on the way until it all pours down into hell.
