Israeli-American startup Stardust Solutions recently received a notable $60 million investment to test technology designed to reflect solar rays to combat global warming. This investment, backed by a broad coalition of investors including Silicon Valley bigwigs and the Italian industrialist family Agnelli, marks a significant step in the development of geoengineering technologies.
Stardust plans to test its particles in the stratosphere in April 2026 by releasing them in a modified aircraft. These particles are thought to reflect sunlight in a similar way to volcanic ash, which could lead to a temporary cooling of the Earth. The company claims that its particles are inert and cannot damage the ozone layer or cause acid rain.
However, Stardust’s technology has been met with criticism. Some experts warn about the potential risks and unpredictable impact on the global climate. Gernot Wagner, a climate economist at Columbia Business School, raised concerns about the commercialization of such technologies by private companies and the possibility that these technologies could exacerbate geopolitical tensions.
The investment in Stardust comes at a time when political efforts to reduce fossil fuels have stalled and global temperatures continue to rise. While some investors are betting on the technology’s potential benefits, the question of whether the risks outweigh the benefits remains controversial. Stardust plans to use the funds to conduct controlled field trials and hopes to win long-term government contracts for the use of its technology.
