Lightning Engineering
11 March 2026 | ZEROGeoengineering.com | Skyward Wildfire is a Vancouver-based weather modification startup that utilizes AI, drones, and planes to inject cloud seeding material into storm systems in a scheme to try to prevent lightning strikes. According to MIT Technology Review, “online documents suggest the company is relying on an approach that US government agencies began evaluating in the early 1960s: seeding clouds with metallic chaff, or narrow fiberglass strands coated with aluminum.”

“But researchers and environmental observers say there are plenty of remaining uncertainties, including how well the seeding may work under varying weather and climate conditions, how much material would need to be released, how frequently it would have to be done, and what sorts of secondary environmental impacts might result from lighting suppression on commercial scales.”

In addition to harmful impacts of man-made aluminum on biological life, military chaff contains Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS), known also as “forever chemicals.” A 2002 PubMed article states: “At least 500 tons of chaff is released annually during training within selected military operating areas in the United States.”
Nevertheless, Skyward Wildfire, which has raised millions of dollars from investors, claims that “safe materials” are being deployed, in documentation published by the World Bank:
