By: L37. Metal refinery - if you use petroleum as coolant and loop it through steam chamber you can get power out of it and never worry about cooling. It actually produces more power then it uses in most cases (depends on metal and dupe skill): Oxygen Not Included. A Screenshot of Oxygen Not Included. The leaky oil fissure is a source of hot oil but if you don't boil it or don't have anything else to heat up with it then I'd just leave it and dig for easier to handle oil. Even if you do find a volcano to boil it you still probably have to cool it first so you can pump it. leaky oil fissures are quite useless as the amount they put out are too weak. being an average emission of 1g/s - 250g/s each. this amount is just not useful for anything in terms of production. its good for early game getting small amounts of plastic or petroleum or oil for anything you need before you get high production. basically a kick star theparmersanking Advice on dealing with an early game leaky oil fissure. Im currently on cycle 580 and i recently found a leaky oil fissure. Ive attempted to build an oil refinment system with it, but after working for about 20 cycles my liquid pump overheated and died. close the leaky oil fissure in with a smallish pit to one side. put a couple of temp shift plates in to help spread the heat. slap a steam turbine on top and dump in some water. just let it kick on at 125c. this is for heat deletion, not power production. Leaky oil fissures are one such case. So really, leaky oil fissures exist in that nice zone of being able to passively activate a self cooling steam turbine. Even if their output rate is trivial, setting one up is equally trivial. 0:00 / 57:14 Oxygen Not Included - Leaky Oil Fissure with Salt Water Boiler - Part 25 Green Gemini 2.12K subscribers Subscribe 1.7K views 2 years ago Hey Everyone!

This is version 2.0 that I've been running for the last 1000 odd cycles. I'm sure many improvements could be made to gain more power from it, but that's not its primary use. Its main use it to get the oil below 275° so the steel pump doesn't melt. The power is just a bonus.
