So, in another thread, @mathmanican was trying to help me figure out how a certain style of infinite liquid storage failed on me. So I figure I'll make a thread to look into that and to talk about infinite gas and liquid storage in general. First up is the system that failed on me. Here is another version of infinite liquid storage I use. I like this one because it's easier to set up and fits in my 4 tall hallway design. Lastly, here's my main method for infinite gas storage. Let me know if you have comments on my probable glitch, questions about any of the builds I use, or have infinite storage systems that you like to use yourself.   PS: Yes, none of these are all that original. I think @Saturnus is responsible for the G shaped door waterfall compressor, but I could be wrong.  The gas storage is based on one of@Lifegrow's designs.
