2025 Patent – Agi Dispersion for Cloud Seeding

17 June 2025 | ZeroGeoengineering.com | International Patent WO2025014351A1 describes an invention for the dispersion of chemicals for cloud seeding with the eventual goal to induce “programmable rainfall.” Silver iodide (Agi) is listed as one of many chemical agents in the patented cloud seeding “solution.” These chemicals are known to be flammable and harmful to health and the environment.

The efficacy of cloud seeding is unproven as stated in the patent: “Although the efficacy of cloud seeding is currently a matter of academic debate, many countries have put significant resources and efforts into direct cloud seeding. Regardless of the fact that there are still no reports of a proven or reproducible direct causal effect of cloud seeding and precipitation, claims of successful correlations underpin international efforts.”

Abstract

“The present invention relates, on the one hand, to the chemicals industry and, on the other, to the service industry, for managing areas where a certain amount of water precipitation in the form of rain is desired. The real advantage of the present invention optimises the number of ice or water droplet-forming nuclei in the clouds where they are applied, in addition to allowing for faster and less expensive cloud seeding, which means that a smaller volume of seeding dispersion has to be handled. The present silver iodide dispersion consists of an ionic solution for seeding clouds, characterised in that the continuous phase, in other words, the solvent of the dispersion, is a mixture of at least 1) toluene, with 2) p-xylene, 3) o-xylene, 4) 2-butoxyethanol, and 5) methylcyclohexane…

…Cloud seeding has been practiced for many years around the world. Scientific papers have reported cloud seeding experiences in the US, Israel, China, South Africa, Argentina, and other countries, as noted below. In general, cloud seeding successes have been documented as statistical differences in the probability of rainfall, rather than direct measurements of cause and effect. Cloud seeding is now considered a potentially very valuable tool for enhancing rainfall precipitation. Research progress has produced encouraging results that will eventually make cloud seeding a practical technique for overcoming draughts by inducing programmable rainfall and developing water supply for many regions. Although the efficacy of cloud seeding is currently a matter of academic debate, many countries have put significant resources and efforts into direct cloud seeding. Regardless of the fact that there are still no reports of a proven or reproducible direct causal effect of cloud seeding and precipitation, claims of successful correlations underpin international efforts.”
