A 8th grade student has successfully turned seawater into drinkable water. The equipment can make 0.95m3 drinkable water from 1m3 seawater in 8 hours. The cost of each equipment is less than $15. The equipment utilises solar heat and a concave reflector to evaporate seawater, leading it through filters and become drinkable water.


This idea is not new; nevertheless the low cost of the equipment and high speed of the process can significant help to solve drinking water issues.
