Yes, I liked sticking with Gregtech, too, so far. But a single tungstensteel large boiler not being able to power a HV turbine seems ridiculous.
The Nitro-Diesel route seems also interesting, this is something I overlooked. Man, the amount of ways to get power in this pack is amazing.
The nitro-diesel is a really good way to get power. At lv you get like 370k eu per bucket. Consider it like a much more efficient version of fuel from buildcraft think its 4x more efficient. You basically get it by mixing
*4 units of fuel (bc or gt doesnt matter) with
*1 unit of glyceryl trinitrate (hydrogen (i think centrifuge compressed cells) and carbon(charcoal dust electrolizes to carbon).
And you get 5 units of nitro diesel.
I automated it last week and the only thing i really need to do manually is supply enough carbon (10 stacks or so last a LOOOOONG time) and 4:5 units of oil. I currently have 9k oil buckets stored and about 2.2k nitro diesel.
I did use the GT distillery to get the fuel since i like to stick to GT but i advise building several of them since that is the main bottleneck. Once you have it set up you have a energy buffer that will prolly last you until the EV stage (hopefully)
Edit: the best part is that you dont have to worry about pipe throughput/max capacity for the nitrodiesel since it will never use 200mb/t (ender flyid conduits) on a single connection. I have 7 lv generators and 1 mv generator all on the same line and it still didnt even get over 50mb/t
and since those conduits can handle 800mb/t on 1 network with a max of 4 input connections it will, like i said, never get maxed out like it does with steam.
