Infinite gas production

[ThePiachu]

So I think I figured out how to make infinite gases. Basically, melt ore in arc furnace to create gas and smelted metal. Toss the metal into the non-arc furnace and get it out to turn it back into ore. Toss ore back into arc furnace to get more gas. Just loop those two, keep feeding it a bit of electricity and you produce gas out of thin vacuum ;).

Fancy! Havent done any more testing, but reported on "magical gases" from ores a while ago! I crosslink your info to my report, too.

If you toss the ores into a cold furnace directly, the gases will be generated inside of it. Then you can take the ore out and put it back in and it'll generate more. It doesn't cost any power and the gases aren't all over the place but neatly packed into a pipeable entity.

But apparently it's intended behavior, see http://steamcommunity.com/app/544550/discussions/2/1621724915766493261/.
