This mod adds steel and machines made from it. Currently there is a machine furnace (for steel), a machine fan, solar panel (level 1), stirling generator and battery.
There are plans to add more machines and solar panels.
I suggest using JEI (Just Enough Items) or a similar mod to show the recipes for the items that this mod adds. The machine furnace recipes aren't shown because they are not vanilla-style recipes, but hardcoded slot checking procedures for the machine furnace.
