One aspect not to be overlooked when installing rugged pods, is to provide something in case one of them flee.
Effectively, we can’t prevent against weather dangers, bad manipulation or willful damage, and some oïl could spread on the ground.
To avoid that, we need to use something to retreive the oil that has escaped, moreover we must keep in mind that some water could be mixed with the oïl (from rain for example).
Our first idea is to use a settling tank:
As oil is lighter than water, the water is evacuate on bottom right side of the tank, the oil stay on top left, we only need to retreive the mineral oil.by
