A company claims it can help cool the planet for $10 billion per year. Stardust Solutions, an Israeli-American company, is working on a plan to produce tiny particles from a food additive and a mineral that hardens eggshells. These particles would be sprayed into the atmosphere to cool the world.

The company is developing solar geoengineering technology, which aims to reduce global temperatures by blocking sunlight. Stardust Solutions was founded in 2023 by two former Israeli government nuclear physicists. The company is focusing on a method that involves spraying tiny particles into the stratosphere.

Further details about the company's plan and the controversy surrounding solar geoengineering are available from the source. Scientists have expressed alarm about the proposal, but more information is needed to understand the potential implications.
