The USS Jimmy Carter makes pure water from the sea water cooling tank and breaks that water down into pure co2 with a co2 scrubber that filters the air through a ton of charcoal. She also uses that pure water to make coffee, ice cream and adds some to the coke cola machine not to mention she makes pop corn for movie night and movie marathons on Saturday.
They also make a lot of noise at 45 kts, but they do not cause Tsunamis
