How do you use beach equipment to get drinking water from seawater?

There are many different ways to make drinking water from salt water

you can let it evaporate and put clear plastic over the water, and leave it

in the sun. It will evaporate and condense on the plastic, the salt will stay

in the container or you can il it and have a container or some contraption

to catch the evaporation and store it in a container you can also start a

fire and boil it, for 7 minutes . But a quicker way to do it is with beach

equipments so you don't need to give in alot of energy to make heat
