This research focuses on formulating a design idea which makes use of solar energy and negative pressure (pressures lower than normal atmospheric pressure of 101.325kPa) to boil (impure) water at temperatures lower than 100oC, producing water vapor which is then condensed to form pure distilled water. Included in this research are estimations and calculations of solar power required to provide energy to boil water as well as a prototype which uses solar power to distill water. The design idea is aimed at people who have water but do not have the means to purify it.
