Talk:Tutorial/Automatic Cobblestone Generator/@comment-83.104.25.242-20121026133806

Put another row of block breakers the other side of the lava, with another row of water, double your cobblestone with the same amount of lava.

Other sources of "natural" EMC include Chicken Eggs, Suger Cane, Pumpkin/Melon farms and Wheat farms. All can be setup to be automated, with various levels of difficulty to the build. I use all 4 methods instead of cobblestone generators.
