How one controversial startup hopes to cool the planet
The Controversial Startup That Hopes to Cool the Planet
Stardust Solutions, an Israel-based geoengineering startup, has made headlines with its ambitious plan to launch specially equipped aircraft into the stratosphere to disperse particles engineered to reflect away enough sunlight to cool down the planet. The company claims that its technology can counteract all the greenhouse gases the world has emitted over the last 150 years, and that it's the "only technologically feasible solution" to climate change.
Stardust's CEO, Yanai Yedvab, says that the motivation for starting the company was to help develop an effective means of addressing climate change. "Maybe something in our experience, in the tool set that we bring, can help us in contributing to solving one of the greatest problems humanity faces," he says.
The company has raised $60 million in funding, led by Lowercarbon Capital, a climate-tech-focused investment firm cofounded by the prominent tech investor Chris Sacca. The funding will be used to advance research, development, and testing for the three components of its system: safe particles that could be affordably manufactured; aircraft dispersion systems; and a means of tracking particles and monitoring their effects.
A For-Profit Approach to Geoengineering
Stardust's decision to pursue a for-profit approach to geoengineering has raised eyebrows among some researchers and experts. They argue that the technology is too complex and sensitive to be left to private companies, and that the risks and uncertainties associated with it are too great to be ignored.
Douglas MacMartin, an associate professor at Cornell University who studies solar geoengineering, says that the company's claims to have developed a perfectly safe and inert "magic aerosol particle" can't be trusted without published findings. "They've ignored every recommendation from everyone and think they can turn a profit in this field," he says. "I think it's going to backfire. Their investors are going to be dumping their money down the drain, and it will set back the field."
The Risks and Uncertainties of Geoengineering
Geoengineering is a highly complex and uncertain field, and the risks associated with it are still not fully understood. The technology is still in its infancy, and there are many questions about its safety, efficacy, and potential impacts on the environment and human societies.
One of the biggest concerns is the potential for unintended consequences, such as changes to the global climate that could have devastating effects on ecosystems and human populations. Another concern is the potential for geoengineering to be used as a tool for geo-political manipulation, with some countries using it to gain an advantage over others.
The Future of Geoengineering
Despite the risks and uncertainties, some experts believe that geoengineering could be a crucial tool in the fight against climate change. "We understand that probably it will not be perfect," Yedvab says. "We understand all the obstacles, but there is this sentiment of hope, or cautious hope, that we have a way out of this dark corridor we are currently in."
The company's investors are aware of and comfortable with the possibility that the technology may not be deployed, and are supportive of the principles that will guide Stardust's work. They are willing to wait for regulations and government contracts, and are confident that the company will find other problems to work with.
Conclusion
The future of geoengineering is uncertain, and the risks and uncertainties associated with it are still not fully understood. However, some experts believe that it could be a crucial tool in the fight against climate change. Stardust Solutions' ambitious plan to launch specially equipped aircraft into the stratosphere to disperse particles engineered to reflect away enough sunlight to cool down the planet is a bold step forward in the development of geoengineering technology.
The company's decision to pursue a for-profit approach to geoengineering has raised eyebrows among some researchers and experts, but its investors are aware of and comfortable with the possibility that the technology may not be deployed. The company is confident that it will find other problems to work with, and is willing to wait for regulations and government contracts.
Ultimately, the future of geoengineering will depend on the ability of scientists, policymakers, and entrepreneurs to work together to develop and deploy the technology in a safe and responsible manner.
