Ice Blocks! (Fresh Water vs. Salt Water) - which is colder? - the tests! (for ice-based air coolers)

fresh water blocks versus salt water blocks. which are colder? i did some tests. mixed up a batch of seawater and froze it then compared it to frozen freshwater. *many people talk about potentially using saltwater ice in the "ice-based" air coolers (to make the air colder). i wanted to see if the saltwater ice blocks are actually colder.
