Steam is produced via vanilla block: a steam engine on a boiler, both triggers tanks to be come a boiler, and acts as an outlet for steam if theres a pipe in front of it.
Steam is not like fluids, it cannot be pumped, nor do the vanilla range-limits apply.
Amount of steam produced (mb/t), is porpotional to the steam engine multi-block level, and SU
Should 2 pipes of steam join, the amount is doubles. and vise versa for splits
axial fans, and centrifugal turbines can turn the steam, into rotating force (bottom face) and even achive up to 250% efficiency gains over a normal create steam engine!
