Stardust Solutions, an Israeli Geoengineering Company, Aims to Cool the Earth with Tiny Particles

Stardust Solutions is an Israeli for-profit solar geoengineering company that was formed in 2023. Stardust claims that its sunlight reflective material can reflect significant amounts of the sun's rays with little or no damage to the atmosphere.

Stardust Solutions' geoengineering particles are made from amorphous silica, which is a food additive, and calcium carbonate, which is in eggshells and limestone. It claims the particles are biodegradable.

A report indicates that Stardust hopes to cool the atmosphere by 1.5 degrees Celsius or 34.7º Fahrenheit!

Solar geoengineering could alter weather patterns, impacting food production and economies, putting over 2 billion people at risk. 

So far, the company has only tested the particles in the laboratory and says it would not test them outdoors unless it were in partnership with a government.

Stardust CEO Yanai Yadveb speaks on being in a "position of power" to create a proprietary blend of sulfur dioxide particles, with the goal of bringing it to policymakers for government implementation. Future goals include predicting the weather. He said that the company aims to disperse particles that will form a protective layer to reflect sunlight away that will balance the warming effect.

Stardust Solutions wants to combat global warming by releasing millions of tons of particles to reflect small amounts of sunlight, NYT reports, but critics warn of dangers in playing with weather
An Israeli tech company has revealed the content of tiny particles it hopes will one day be used to combat global warming by scattering millions of tons of them into the atmosphere to reflect away sunlight, the New York Times reported Thursday.

Stardust Solutions had previously kept the makeup of its geoengineering particles a closely-guarded secret, protected with nondisclosure agreements.

As it turns out, they are made from amorphous silica, which is a food additive, and calcium carbonate, which is in eggshells and limestone.

The company, which is led by former figures from Israel's nuclear program, on Thursday began publishing research papers on its product.

The idea is to disperse the particles at high altitude where they would reflect sunlight, cooling down the Earth.

"This is a very powerful tool that will be ready for testing very soon, and we want policymakers to start thinking seriously, 'What will it take in practice?'" chief executive, Yanai Yedvab, told the Times.

So far, the company has only tested the particles in the laboratory and says it would not test them outdoors unless it were in partnership with a government to lay down the rules and limits of the test, according to the report.

Founded in 2023, Stardust Solutions has pulled in $75 million in funding from investors and has applied for a patent. Registered as a US company with an Israeli subsidiary, it has a lab in Ness Ziona, south of Tel Aviv.

The company has two types of particles it is working on. The first could reflect up to one percent of the sunlight, while the second, still in the testing phase, could reflect more than that.

Stardust executives estimate that a starting project to begin cooling the atmosphere could cost around $10 billion. It would require some 10 million tons of particles dispersed over several years, aiming to cool the atmosphere by 1.5 degrees Celsius.

It says the particles are biodegradable, not harmful to people or animals, and would not build up in the soil or oceans.

However, the idea of meddling with the world's weather faces pushback.

More than 600 scientists and academics have called for an international ban on such projects, while Tennessee and Florida have already banned geoengineering.

Critics cite concerns of unintended consequences and that artificially cooling the planet might lessen calls for countries and industries to cut back emissions that are causing climate change. However, in recent years, as global temperatures have gone up, many researchers and some environmentalists have been more open to studying solar geoengineering methods, the report said.

Prakash Kashwan, a professor of environmental studies at Brandeis University, has warned that solar geoengineering could alter weather patterns, impacting food production and economies.

He highlighted those who live in South Asia, East Africa, and Latin America, where annual monsoons are vital for crops.

"There's this social risk for at least two billion people that is directly connected to the lack of scientific understanding about how interfering with the global temperature thermostat is going to interfere with the monsoon formation," he told the Times. "We don't have a solution for those kinds of risks."
