We proposed a multifunctional breakthrough project "Sunny Rain", which provides a solution to the most pressing problems of mankind. I wrote multifunctional breakthrough inventions [1,2] and articles [3-7]. The rain invented for the first time and presented in inventions [1,2] was called "Sunny Rain". An inexpensive way to create "Sunny Rain" condensation nuclei was invented and directions for its use to solve problems were proposed: obtaining water and capturing other greenhouse gases from the cloudless atmosphere in industrial quantities in the Arava, Negev and other problems.

When I get a grant, I will become the founder of a startup called “Sunny Rain International”. The "Sunny Rain" project will be in Israel, then in other countries. A pilot project for the distribution of Sunny Rain is planned to be implemented in Singapore.We plan to build the startup infrastructure within some months. Then we plan to produce experiments of solving problems A1)- A9):

A1) Obtaining water.

Note A1.1: Production of water from a cloudless atmosphere in industrial quantities,which is possible because the amount of water in the atmosphere is currently 14 thousand km³, while in all river beds there is only 1.2 thousand km³. Thus, humanity has a gigantic source of water in a cloudless atmosphere, and the “Sunny Rain” Project describes the technology for obtaining this water.

Note A1.2: Rain production is optimal at the maximum temperature because density of water vapor in air ρ(h,T) is largest for largest temperatures T (see Fig.2.  where ρ(h) calculated at relative humidity 80% using formula derived in [1]). Then compute M(H)=0Hhdh. We shall calculate M(H) at relative humidity æ=80% and present the results in Figure 3. Knowing M(H) allows us to determine the optimal flight altitude of the aircraft.

Note A1.3: "Sunny Rain" may be used for effective irrigation (see A3)) and using: membrane water purification plant [11] and Kitchen Activated Carbon Water Filter [12] for drinking water.

Note A1.4: It is possible to obtain water in Arava, Negev. 

Note A1.5: "Sunny Rain" may be used for effective irrigation (see A3) and using: membrane water purification plant [11] and Kitchen Activated Carbon Water Filter [12] for drinking water.

Note A1.6: An article by XPRIZE CEO Anousheh Ansari was published in Fortune. Faced with a global water crisis, this article highlights the harsh reality that 40% of the worlds water needs could go unmet by 2030 as desalination technologies plateau, making the need for innovative solutions more urgent than ever. So, the application of “Sunny Rain” is critical. [13]

A2) Cooling the air in one place in the city, which will save a climate catastrophe in that place in the city.

Note A2.1: The old policy is mainly based on the Paris Agreement on reducing greenhouse gas emissions and, first of all, on achieving carbon neutrality. But the amount of greenhouse gases CO2 (CO2 9-26%, Methane CH4 4-9%, Ozone O3 3-7%) is significantly less than the amount of greenhouse gas water vapor (water vapor H2O 60%). Therefore, further attempts to reduce the amount of

greenhouse gases CO2 will not be successful in solving the climate crisis and other problems.

Note A2.2: The “Sunny Rain” strategy is based on two physical effects: 1. "Sunny Rain" will destroy greenhouse gases; 2. Evaporation of water in the air and on the Earth. First, "Sunny Rain" destroys all greenhouse gases, which leads to cooling of the air more significantly than the old policy. Second, evaporation of water in the air and on the Earth is a powerful means of cooling the air. Thus, the new policy for solving the climate crisis is significantly superior to the old policy. 

Note A2.3: In addition to solving the climate crisis, the new policy provides solutions to other problems. Current policies cannot keep up with the rate of environmental degradation we are facing today. With current policies none of the environmental goals (e.g. the Paris Agreement on carbon neutrality) will be met. As a result, we are facing a planetary crisis.

Note A2.4: Iran has announced Wednesday and Thursday this week will be public holidays because of "unprecedented heat" and told the elderly and people with health conditions to stay indoors, Iranian state media reported. [14]. 

Note A2.5: A French nuclear power plant was shut down due to the shallowing of the river that cools it. Sunny Rain can be used to irrigate rivers because the atmosphere contains 12,900 km3 of water, while rivers contain 2,120 km3 of water.

Note A2.6: By 2040, the Euphrates and Tigris will dry up due to declining water levels and droughts caused by climate change.

Note A2.7: A giant wildfire in the US destroyed part of Los Angeles in January 2025. Without Sunny Rain protection, rebuilding Los Angeles is pointless as temperatures are projected to rise further in 2026–2030 and the rebuilt city will burn again in future fires in 2026–2030!

A3) “Sunny Rain” will double food production.

Note 3a. The Ministry of Agriculture issues research grants to prepare Israel's agriculture for warming, which is a matter of survival. According to the ministry, some 5.5 million shekels have been given to scientists in the past two years. The development of heat and drought resistant varieties is recognized as the most important area of adaptation to warming. Prof. Peleg views the future of this area with pessimism. He is convinced that famine is inevitable in many countries and that there is little time left for preparation, as it takes 10-15 years to bring a new crop variety to market. Сrop variety takes 10 to 15 years to bring to market.” 

[5]. Our proposed approach to adaptation to warming is Efficient Irrigation with Sunny Rain.

Note 3b. Based on experiments described in the literature. In addition, harvesting

from former semi-deserts and deserts and eliminating droughts with the help of

the obtained water from “Sunny Rain” will increase food production.

Note3c: Plant leaves absorb CO2 from the air in the light using chlorophyll and convert it into organic matter along with the mineral-rich water with mineral-rich water that reaches the leaves from the root system. “Sunny Rain absorbs all greenhouse gases, including CO2 and H20. Thus, the use of solar rain results in an increase in crop yields.

A4) Putting out fires.

Note 4: The amount of water in the Sunny Rain is significantly greater than in 40t firefighting aircraft.

A5) Creating good ecology (clean the air above cities, which increases the life

expectancy of people).

Note 5.1: A World Health Organization report in recent years states that fine particulate matter in Israel is four times higher than recommended levels. In Israel, about 2,400 people have died due to air pollution. In comparison, 355 people died in traffic accidents in the country that same year. Many residents living near polluting industries and facilities suffer from particles entering their respiratory system and bloodstream, which harms their health. There is a link between exposure to fine particulate matter during pregnancy and problems with the development and delivery of the fetus, such as low birth weight and birth defects. Pollution has a cost not only in terms of disease, but also in terms of costs to the economy. The latest emission inventory report from the Ministry of Environmental Protection states that the cost of industrial pollution in Israel, excluding greenhouse gases, reaches an imaginary sum of almost 5.5 billion shekels per year to the economy (5,442,445,975). Professor Nir Becker, a researcher at Tel-Aviv Academic College, checked and found that the economic damage from Haifa Bay pollution due to diseases and excess mortality is estimated at about NIS 1.36 billion per year, according to the OECD.

Note 5.2. Air cleaning from pollutants (including microplastics) with water produced by “Sunny Rain”.

A6) Eliminate unwanted dense fog at airports.

Note A6: USA and British companies are losing billions of dollars because unwanted dense fog at airports.

A7) Increase of water in shoaling rivers

Note A7.1: A French nuclear power plant was shut down due to the shallowing of the river that cools it. Sunny Rain can be used to irrigate rivers because the atmosphere contains 12,900 km3 of water, while rivers contain 2,120 km3 of water.

Note A7.2: By 2040, the Euphrates and Tigris will dry up due to declining water levels and droughts caused by climate change.

A8) Sunny Rain can be used to irrigate cities, shrubs and trees on mountain slopes and in semi-deserts

Note A8: The World Health Organization recommended the availability of a minimum of  9 m2 of green space per individual.

A9) Condensation nuclei will help firefighters rescue people from smoke-filled rooms during fires.

Summary: 1S) Based on the results of the calculations, scientists came to the conclusion that the limit of safe temperatures for humans cannot exceed 35 degrees. "Dangerous" heat is defined by the US National Weather Service as 39.4 degrees Celsius. "Extremely dangerous" - 51 Celsius. Such a temperature can cause harm to a person, even if he leaves the house for a few minutes. 

Average temperatures in July in Israel from +24 to +37 °C.

The hottest month of the year in Singapore is June, from 26 °C to 31 °C.

2S) Thus, given that the planetary boundaries of the climate change process, within which the Earth is suitable for life, have long been violated and the world is moving towards destruction at high speed, we need to activate the invented technology "Sunny Rain" as soon as possible. To prevent humanity from repeating the fate of the Neanderthals, it is necessary to first stop the rate of growth of greenhouse gases, and then achieve a decrease in the amount of greenhouse gases, achieving a comfortable temperature for people all the time.

Then we will serve kibbutzim, businesses, cities in Israel and other countries, since "Sunny Rain" is needed by almost everyone on earth. A pilot project for the distribution of Sunny Rain is planned to be implemented in Singapore. If countries follow the recommendations of the new "Sunny Rain" project, the amount of greenhouse gases and the air temperature above the Earth will decrease significantly, which will benefit all countries of the world.  

Therefore, it is necessary to create a new Conference (water; urban cooling and climate change; “Sunny Rain”; decarbonization; prevention eruptions of shallow underwater volcanoes; ecology; firefighting; food) similar to the Paris Climate Change Conference of 2015. 

WMO informed: “There is a 98% likelihood that at least one of the next five years, and the five-year period as a whole, will be the warmest on record.”  If Temasek Foundation does not set up a Sunny Rain base in Singapore, the city's temperature will continue to rise. Summary: 1S) Our mission now is to save humanity from climate change and solve other world problems! Sunny Rain technology so that humanity does not repeat the fate of the Neanderthals!  

2S) Based on the results of the calculations, scientists came to the conclusion that the limit of safe temperatures for humans cannot exceed 35 degrees.
