You will find everything there, especialy why your efficency is so low.
That page was very helpful although it didnt explain my lack of efficiency. But nevertheless i finally found it! i swapped from an HV Dynamo Hatch to an EV Dynamo hatch and ran my tests again.
I now get 1.073.150 EU from a 60 sec run. that is almost on par with the LV Gas turbine, probably better if i include transformer losses.
willis936 i didnt need fludi regulators in this case since i used a single Ender IO Fluidduct (highest tier) to pump the biogas in. and since the turbine couldnt comsume it faster than i supplied it i dont think my supply of Biogas was the problem.
Thank you guys very much !
Now my last question:
the wiki says that a Turbine may comsume up to 150% of its optimal flow, but that it will waste the surplus Gas.
Does that mean that i cant just pump all my Biogas in and that I need to supply EXACTLY the optimal flow to the turbine?
