Scientists are very interested in finding scientific solutions to the water crisis that many of the inhabitants of the earth know. Until now, about 1.1 billion people around the world have been counted who do not have a source of fresh water, and 2.4 billion suffer from diseases caused by corrupt water, which is a crisis that can increase its severity. In the near future, according to many scientific reports.

Therefore, researchers from Japan and China are working on making the Direct Solar Steam Generation (DSSG) technology to collect water by using the sun's heat possible on the ground.

Because it appears to be one of the most effective scientific solutions for producing water at the lowest cost.

This technique is based on capturing the sun's heat, which is converted into liquid and then into water vapor, so that it can be filtered and desalinated, then it is cooled and converted again into water that can be used for drinking and daily needs.

Obstacles on the ground

According to the study - which was published in the journal Solar Energy Materials and Solar Cells, in its latest quarterly issue until next January;

This ambitious and simple technology faces obstacles in order to implement it on the ground and make it commercial.

Scientists believe that the scientific research on the techniques of converting steam into water has theoretically reached its limits, and that it is now necessary to go towards deepening technological research in order to make the devices used more powerful and effective in capturing the sun's heat, and to reduce the leakage of this heat.

Thus producing the largest amount of water possible.

Weather fluctuations are one of the most important problems facing the application of direct solar steam generation technology (Li Miao-Uric Alart)

Professor Li Miao, one of the study participants, said in the press release issued by the Shibaura Institute of Technology in Japan - “Our goal is to study all technologies that depend on steam, and analyze them to find out their shortcomings so that we can develop technology to generate Direct solar steam, and make it applicable to the ground. "

The sun is always the source

And it seems - according to what was stated in the statement - that all these technologies are based mainly on capturing the sun's heat, which can make them more effective in areas where the sun shines many hours a day, and if scientists can make it less expensive, it will become very suitable for many Low-income countries that enjoy good sunshine, such as Arab countries.

Earlier, researchers were able to develop a technique called "direct contact mode", which allowed to reduce the percentage of heat leaks and limit them to only 15%.

This was followed by the "indirect contact pattern" technique, which in turn contributed to the development of another, more effective technology called (1D Water path), which restricted thermal leaks to 7%, and then came many effective technologies that depend mainly on the sun's heat.

According to the press release, there are many other techniques that researchers must solve their problems, especially with regard to the need to adapt to external weather fluctuations.

Nevertheless, the pace at which work on this technology is advancing makes it a hopeful topic, Professor Miao said. “The road to practical implementation of the direct solar steam generation technology is full of problems, but given its advantages, there is an opportunity to become one of the leading solutions to our growing problem. With the scarcity of fresh water. "
