ill add solid fuel soon i was thinking of it too
i chose light and heavy since petroleum gas goes usually to plastic and H2SP4
and i didnt want a competition on that resource
thanks a lot ^^ i will be able to run my entire factory on oil really CPU friendly ( less ploom of vapors coming out of the turbines )
i really wanted to go full steam, but the setups needed to be so huge, too much cpu for me ( at least, when you compare with nuclear ^^ wich is more cpu friendly )
