So I decided to try using the new in-pipe thermal sensors to create a feed back loop allowing a single Thermo Aquatuner to bring a feed of liquid down to a specific temperature.  Using the free oil from a leaky oil fissure, I decided to create a pool of petroleum at around -50c.  Other uses include sending cold water to sleetwheat.  For the petroleum pool I want, the process is somewhat slow.  As it comes out of the refinery, petroleum is about 74c, so it has to go through the aquatuner about 9
