There is no methane sources in IHL. Do you suggest to add them?
Do you actually mean (played) IHL? May be this was a wrong thread? Chocohead answered on your question.
There is already 2 types of electrolysis facility in IHL. I can add arc furnaces, but for what purposes?
You are welcome to suggest new crafting recipes for another mod items using IHL items. As well - new recipes for IHL machines to process items from another mod items or to process current items into other mod items. This very easy for me. As well you may suggest something entirely new, what you really want, but wasn't fulfilled in IC2 or GT.
DudeWithOldTextures, i think you simple misclicked "Advanced machines" addon thread, yes?
