Energy Types and Efficiency
So, to sum up the previous tasks, you used heat (measured in HU/t) to power a Boiler (which converts HU/t to Steam/t) to power a Turbine (which converts Steam/t to RU/t) or an Engine (which converts Steam/t to KU/t) to power a Rolling Mill (which converts RU/t to internal GU/t) or a Squeezer (which converts KU/t into internal GU/t), and in the case of the Squeezer, transferred its content into a Coagulator (which uses time as a resource, measured in ticks (t), or seconds (1 sec = 20 ticks)).
