Will drones make cloud seeding more effective?
Rainmaker, a startup based in San Francisco, has begun using drones to disperse silver iodide for cloud seeding in Alaska, generating a reported 19 million gallons of water in three hours. However, environmental concerns have been voiced regarding the safety and effectiveness of the seeding process, which some experts argue only marginally improves rainfall. While the technology's evolution via drone utilization marks an innovative approach, its actual contribution to solving water scarcity remains questionable, with communities expressing skepticism on its long-term benefits.
