Well, we kind of see this power equipment as a tiered system. Redstone/Steam engines for early game (easy to set up, takes a great deal of maintenance/management to use constantly), magmatic engines and similar for a kind of mid tier (larger up front cost, but lower maintanance requirements, like just moving the pump around the nether), and then fission and fusion reactors as a final tier (massive up-front cost with the benefit of much less constant babysitting, throw a fuel rod in and it lasts a long time, keep it maintained with computers watching and no issues).
It's kind of what we're looking to create, as we always felt nuclear power would fill that gap at the end for us. As it is, I don't really want to pipe everything and everything to a fusion reactor, nor do I want a million deuterium rods being made just to run the reactor for a day. It's insane to me. Yes, I could run pipes and auto workbenches, ect., but it's not really what we're looking for.
