ELI5 means assume I have zero understanding of anything!

> is so bad I don't know where to start. Though for a first step where do you think that energy you extract from the water to turn it into ice goes

You are not extracting energy from water, the energy comes from nuclear fission in nuclear powerplants.

> If you want to use ice cubes they have to either be made in space

Why? You have a giant power plant getting energy from nuclear radiation and it's entire purpose is to generate 1-2 square km of ice sheets each 1M thick along with 10-20 other plants you have 300-600 sq km of ice per year that is intended to keep polar surface ocean water cool (not the whole world).

The goal is not to cool the air but to essentially use nuclear energy to transfer heat from the ocean into steam into the atmosphere.
