So my previous post had some good feedback, and I've improved my design and incorporated some other elements. In particular, magma efficiency has gone through the roof, and capacity has increased.
Produces:
4.5 kg/s Oil -> Natural Gas
0.25 kg/s Magma -> Igneous Rock
That's an increase from 1 kg magma : 1.25 kg natural gas, to 1 kg magma : 18 kg natural gas.
The major change is the thermally buffered doors, which drastically increase magma efficiency, at the cos
