Not indestructible, it just can take a doublesized Nuke-Explosion without a scratch.
I noticed something with NEI with some cells, some of the cells you can use as fuel... there is heat number next to them like hydrogen cells they give 12k heat. What is this suppose to mean? that I can use them in a regular furnace to make titanium or aluminum?
I dont know. Ask mistaqur, he made the plugin, he should know that. But I think its for Steam Boilers of Railcraft.
