Expansion of water demand due to rapid population growth, drastic climate change, increasing energy consumption and other reasons has caused the severely scarce water resources to face greater challenges. Authoritative organizations predict that the world will face a "water bankruptcy" crisis in 20 years. If humans still use water resources at will, as usual, the global economy will face a collapse. Water resources may be more expensive than oil in the future.
The global water crisis has become a roadblock on human development. How to break through it is a problem that countries around the world have to consider.
Chemical water production: high cost and risk
In middle school, we learned that hydrogen and oxygen get water through a chemical reaction. But at normal temperature and pressure, hydrogen is a gas that is extremely flammable, colorless and odorless. There is no hydrogen in the natural atmosphere, and modern industry generally produces hydrogen from natural gas or water gas. If oxygen and hydrogen are used to make water, not only is the cost prohibitive, but there is also a risk of explosion. Therefore, the production of water through chemical reactions only occurs in the laboratory, and it cannot be applied to real life at present.
Seawater desalination: high threshold + long distance
The ocean contains more than 1.35 billion cubic kilometers of water, accounting for about 97% of the total water on earth. How to desalinate seawater into drinking water has become the focus of many scientists. The latest solution is to apply the reverse osmosis method, which has the advantages of simple equipment, easy maintenance and modularization of equipment, and gradually replaces the distillation method as the most widely used method.
However, seawater desalination is costly and not easy to transport over long distances, which restricts the use of poverty-stricken areas, inland or high-altitude areas. However, these types of areas lack the most freshwater.
Make water with air: if there is air, there is water
As early as 1989, Mr. Zhou Mingyang, a Chinese meteorologist, put forward the theory of air to water, and later cooperated with Shenzhen Tianquan Air Water Intelligent Technology Co., Ltd. and served as the chief scientist of Tianquan to transform and deepen air water technology R & D.
In 2009, the "air water maker" developed by Tianquan obtained the "utility model" patent from the National Patent Office;
In 13 years, the "air water maker" won the "invention" patent of the National Patent Office;
In 15 years, successfully launched the second generation of Tianquan air water making machine, without the traditional water source, directly absorbing water from the air, plug and drink, and through air purification, water purification and other treatments to make the effluent meet the standard of direct drinking water, as a water Poor areas and areas with severe water pollution provide a perfect drinking water solution.
