Would it be possible to genetically engineer humans to be able to
drink sea water?

Obviously this would be quite useful as there are many places where it’s hard to get freshwater, and most of the water on the planet is salty. Unfortunately we dehydrate very quickly if we drink it on its own, because our kidneys have to get rid of more water than we would actually take in from the seawater to get rid of the extra salt. This happens because we can only make urine with a certain level of saltiness, because the tubes in our kidneys that concentrate urine, known as the loops of Henle, are of a fixed length.
