What's wrong with Power converters?
Railcraft has a Steam Turbine Multiblock structure which generates 100EU/t for 320 Steam/t (or 200 EU/t if you use RC 7.2.x.x)
I've never used Steam power before, is it simple to learn?
I hear you that finding lava is very easy and lava is overdone... I was just answering your question. How do convert MJ to EU and generally speaking what I have read people use is the magma crucible route.
