Water covers 70% of our planet, and it is easy to think that it will always be plentiful. However, Only 3% of the world's water is fresh water, and two-thirds of that is tucked away in frozen glaciers or otherwise unavailable for our use.
As a result, some 1.1 billion people worldwide lack access to water, and a total of 2.7 billion find water scarce for at least one month of the year. Inadequate sanitation is also a problem for 2.4 billion people.they are exposed to diseases, such as cholera and typhoidver, and other water-borne illnesses. Two million people, mostly children, die each year from diarrheal diseases alone.
At the current consumption rate, this situation will only get worse. By 2025, two-thirds of the world's population may face water shortages. The time has come to realize the need and necessity of an efficient distillation device that is not too big, and con easily generate clean water anywhere.
The PROSAVE has developed of atmospheric seawater desalination system using solar thermal energy. We were able to provide enough clean water in the water scarce regions of the world.
We hope the all of the country with severe water shortages lead to enjoy an opulent lifestyle & happy life through this water supply.
