Making soap using banana tree ashes and animal fat

A cloth impregnated with seawater is wedged between two frames on which transparent sheets have been stretched. Thanks to the sun and two reflectors made with a cover of survival, the water of the fabric will evaporate then come to trickle on the baches, while the salt will remain trapped by the fabric. The desalinated water flows down the frames and is collected in a can with two pipes. At the bottom of the frames, waterproofness is essential to the proper functioning of the desalinator.
