With Stardust Solutions poised to begin geoengineering experiments, ICAN Legislate is sounding the alarm to members of Congress.
Through its legal team, ICAN Legislate wrote to US Representatives Tim Burchett, Thomas Massie, and Tony Wied, warning of the dangers that geoengineering poses to our health, the environment, informed consent, and national security. ICAN urged the congressmen to initiate a congressional investigation into Stardust Solutions, a US-Israeli geoengineering start-up that may be collaborating with US federal agencies in ways that are not clearly disclosed to the public.
To date, Stardust has raised $75 million in funding to deploy for-profit solar geoengineering or solar radiation management (SRM). An internal company presentation reveals that Stardust plans to:
- 2027: Start a gradual demonstration to lower temperatures.
- 2028: Sign contracts, possibly with U.S. government agencies.
- 2030: Conduct a large-scale demonstration and aim to earn around $200 million yearly from government contracts.
- 2035: Move toward global full-scale deployment of their geoengineering technology.
Alarmingly, Stardust CEO, Yanai Yedvab, said that Stardust already has enough money to start “outdoor contained experiments” in the stratosphere as soon as April 2026—so it is possible these experiments may already have begun.
While Stardust claims its system is “safe, measurable, adjustable, and fully reversible,” it has provided no evidence to substantiate that claim. To the contrary, leading geoengineering advocates like David Keith and Kelly Wanser have publicly criticized Stardust’s opacity, unsupported representations, and its push to accelerate SRM deployment. In fact, Stardust’s own April 2026 white paper, co-authored by CEO Yedvab, concedes that “risks associated with SAI implementation are inevitable” and that “meeting safety requirements does not ensure safety at a 100% confidence level against all risks and under all possible scenarios.”
ICAN Legislate will continue to investigate and keep you updated as we learn more.
