TRADITIONAL
In many
countryes people is used to have electric power everywhere, even there is
people used to have a sort of fridge in the car.
Here in
Ethiopia is not that easy but sometimes is even more effective.
In this
picture you can see those bottles that have around a rope. This rope is not a
casual thing, is just a way to get cold water. May be it sounds estrange but is
true. If someone wet the rope with water and put the item under the sun the
evaporation of the water in the rope makes the water inside the bottle cold.
There is the
simplest version introducing a small bottle in a wet sock. Put it under the hottest
sun and you will get fresh water!
