Stardust, an Israeli-U.S. startup, intends to patent its unique technology for temporarily cooling the planet.

In July 2012, a renegade American businessman, Russ George, took a ship off the coast of British Columbia and dumped 100 tons of iron sulfate dust into the Pacific Ocean. He had unilaterally, and some suggest illegally, decided to trigger an algae bloom to absorb some carbon dioxide from the atmosphere — an attempt at geoengineering, a tech-based approach to combating climate change. It was a one-off, the largest known geoengineering experiment at the time, and a harbinger for more to come.
Now a startup called Stardust seeks something more ambitious: developing proprietary geoengineering technology that would help block sun rays from reaching the planet. Stardust formed in 2023 and is based in Israel, but incorporated in the United States.
Its approach is novel: Most geoengineering research today is led by scientists in the U.S. at universities and federal agencies, and the work they are doing is more or less accessible to public scrutiny. Stardust is at the forefront of an alternative path: One in which private companies drive the development, and perhaps deployment, of technologies that experts say could have profound consequences for the planet.
