The team wanted to see solution for people living in hot countries where there is too little water such as in Africa.
Especially as there would be no water to drink.
The idea is very simple. It is a windmill, with a collection tank. The water would be sucked up by the windmill which works on wind, and as the water is being sucked up it would pass through a cleaning filter and so be ready to drink.
The windmill would serve one family.
