How much desalinated water did you get? how effective was the solar still in distill the salt water? taste your desalinated water and then the salty water. why does the desalinated water taste different than tap water? discuss the operation of your solar still in terms of thermal radiation, conduction, convection, the change of state of the water, and the conservation of energy. does the size and shape of the outer (evaporating) container affect its efficiency? does the depth (volume) of water in the evaporating container affect its efficiency? any suggestions for improvements?
