Thaumonic engine. It would be a buildcraft engine that produces more or less MJ/t depending on the number of nodes you place around it, maxing out at 16 MJ/t (16 nodes).
Nodes would take up a lot space, it also seems somewhat overpowered to have an energy source that costs essentially nothing. Maybe the engine could run on certain types of essentia. Essentia can be automated with golems, so the power generation won't be build and forget but it can be automated.
