Overview
- Stardust released a 14-page white paper that lays out safety rules for research that aims to cool the planet by reflecting sunlight.
- It urges use of materials safe for people and ecosystems, calls for designs that can scale up or down, and requires precise monitoring tools.
- The firm is developing a proprietary reflective particle and stratospheric spray and tracking systems to operate about a dozen miles above Earth.
- Company leaders say they will permit use of the technology only if a national government deems it safe and necessary to limit extreme warming.
- The documents do not reveal what the particle is, and the CEO told The Atlantic the company plans to unveil details in the coming months as scientists press for public oversight of private efforts.
