My project is a backpack that transforms sea water into fresh water through evaporation of it, I have chosen this project because there is very little fresh water in the world and a lot of salt so I have thought about being able to give it a little more use to sea water, with this I solve or at least take a small step to solve the lack of fresh water around the world.

For what is the backpack in general I have used a kind of fairly resistant fabric, to make the mechanism inside I have used a piece of red wood to simulate the heating plate, two plastic bags, one for salt water and one for fresh water, another plastic bag and wire for the funnel, a rubber tube, cords for the closure of the backpack and some handles as for the blinds.
