Title:
DESERTS' WATER GENERATION THEORY AND ITS PRINCIPLE APPLICATION — AN EASY WAY TO OBTAIN FRESHWATER FROM THE ATMOSPHERE
Document Type and Number:
WIPO Patent Application WO/2019/059960
Kind Code:
A4
Abstract:
Applicant discloses a new viewpoint and its application for freshwater generation here: Air temperature exchanges between the inside and outside of the deserts always play an important role in the generation of freshwater in a desert environment. Because this procedure is continually happening through days and nights and the desert area is so large in the world, the amount of water production by this way is extent to people could be imagined. According to the viewpoint disclosed here, big benefits will be gained from taking over the plight of shortage of water for the development of the desert. According to this doctrine, the easiest way to collect water from the desert is setting an impermeable layer under the dune: the fresh water should flow out. By use of artificial stacked large amounts, sands can also obtain freshwater anywhere where the changes of the temperature are big.

AMENDED CLAIMS

received by the International Bureau on 31 May 2019 (31.05.2019)

Claim:

[0048] 1, The principle of my viewpoint of water generated from the atmosphere -vapor outside and inside of the desert condition, the viewpoint application, and the complete opened system which by use of the method of with natural day-night temperature difference cycle condition to subsequently create heating and cooling cycle apply to the sand/stone or any other substitute where moisture can be condensed on its surface or inside gaps to obtaining freshwater directly from the atmosphere by using the temperature exchanges between the air and sand or stone or any other substitute where moisture can be condensed on its surface or inside gaps by use of the air path through between said the sand-piles or any other substitute where moisture can be condensed on its surface or inside gaps following the constant negative pressure in the direction of persistence which superimposed under the bottom of the produced water layer caused by sinking of the water gravity.

[0049] 2, the process according to Claim 1 said the method is using day and night temperature differences to achieve sands at low temperature and low temperature regenerated by the night cold airflow caused by negative pressure to pass through the gaps between the sand or substitute to obtain the condensed freshwater.

[0050] 3, the process according to Claim 1 said the negative pressure can be auxiliary to increase by use of the air well, which generates a direction constantly negative air pressure and said the air well connects with the space under the sand-pile (or any other substitute where moisture can be condensed on its surface or inside gaps) which the water can flow to the store pool or tank and let the air be sucked back out from the space under sand-pile or its substitute where moisture can be condensed on its surface or inside.

19 [0051] 4, the process according to Claim 3 said the direction constantly negative air pressure means the direction constantly negative air pressure is from outside of the sand-pile or any other substitute where moisture can be condensed on its surface or inside gaps into the inside of the sand-pile and passes through the space of the water pool and comes back to said air well.

[0052] 5, the process according to Claim 1 said the temperature difference is based on the natural daily temperature changes between day and night time, and the temperature changes affect the air temperature changes and therefore cause the sand pile and its substitutes’ temperature change following the temperature changed air which is sucked into the sand pile and its substitutes.

[0053] 6, the process according to the claim 1 said the sand-pile substitute means any object bodies that the moisture could be condensed on their surface or inside gaps, which their permeability and water absorption are better, substitutions.

[0054] 7, the process according to Claim 1 said the air well connects with a space where the water can be collected and the negative pressure can pass through in order for the air to come back to the atmosphere by the air well from the sand-pile inside after the water is collected. The moisture in the air is condensed on the surface of the gravel and is collected directly without any additional re-evaporation-condensation process before being collected, also without further contact with the original air space before the water be collected.

[0055] 8, Any changes of improvement to the application and its methods for increasing freshwater production based on this principle are involved. For example (never be limited) use blower to increase the speed of air passing through the gravel pile. Or, use any added energy to

20 refrigerate the environment inside the sandstone or its substitute pile to increase the production of condensed water.

[0056] 9, In Claim 1 , said the viewpoint principal and the method can be used anywhere on the Earth.
