Name: Rock Melter or Lava Maker
Description: This machine uses a very high electric current to melt ordinary rock into lava. This takes an extraordinary amount of energy and is rather slow, but can turn a stack of cobblestone (64) into a full tank of lava, enough to fill 8 buckets or cells. For balance reasons, this will take more energy per bucket/cell than one can get out of a lava bucket or cell, and most likely much more.
Recipe: At least one Induction Furnace to generate the heat and some obsidian to be able to take the heat, plus most likely other components.
Combine with http://forum.industrial-craft.…page=Thread&threadID=6209 (The Molten Electrolyzer) to extract metal from ordinary rock! (very slowly)
