I use some mods, that require energy conversion, rf to eu, but i can only find Electric Flux Generators, thera are no flux generators available in the game, and i don't know why, and how to make it appear, please help me

Were removed do to impossiblity to balance RF to EU.
Back then it was 40RF => 1EU and 1EU => 4RF, I am not planning to read RF => EU support again.
