Ic2 machines using RF

I saw a direwolf20 video recently where he was showcasing an Ic2 release where machines were directly producing RF. I can't find anything else about this though. Was this canned? Is there any version of ic2 I can play that does not in fact use EU? Not gonna lie, ic2 is my favorite tech mod because the machines are fast, simple and it's nostalgic but being able to have a single power generation source would be be cool
