I had intended to make a machine that runs off of lava PLUT, but it turned out to be harder than I expected @_@;
This machine could technically produce lava faster, but it's the first one I've made that uses an inverted E-wall, and pressure switches for controlling the reaction. :D
@Catelite Which conditions though? I've never seen that before. (Or perhaps just incorrectly assumed it was the metal casing...) I'll have to investigate... ;-p
