The Download: a controversial proposal to solve climate change, and our future grids

This edition covers an Israel-based geoengineering startup that says nations will soon pay more than a billion dollars a year to reflect sunlight and cool the planet, and a look at how a publicly owned utility plans to reach net zero by 2040.

The newsletter leads with a profile of Stardust Solutions, an Israel-based geoengineering startup that plans to launch specially equipped aircraft into the stratosphere to disperse particles engineered to reflect sunlight and cool the planet. The company says it expects nations will soon pay more than a billion dollars a year for such services and claims the approach could avoid environmental side effects. Numerous solar geoengineering researchers featured in the piece are skeptical both that Stardust will secure the customers needed for global deployment in the next decade and that a private company should have authority to influence the global temperature.

Another feature turned into the MIT Technology Review Narrated podcast examines a publicly owned utility in Nebraska as it confronts the trade-offs among reliability, affordability, and sustainability. The utility has set a target to reach net zero by 2040 and the story outlines the operational and policy choices it plans to use to meet that goal. The Narrated series is distributed weekly on Spotify and Apple Podcasts, where listeners can follow ongoing coverage of energy and infrastructure transitions.

The newsletter’s curated must-reads highlight global policy and technology flash points. Australia’s social media ban for teens has just come into force and opinions are sharply divided, while climate reporting notes this has been the second-hottest year since records began, with mean temperatures approached 1.5°C above the preindustrial average. Technology items include reporting that OpenAI faces competitive pressure, that Silicon Valley is working harder than ever to sell Artificial Intelligence to consumers, and that there is a wider push for shared standards for Artificial Intelligence agents. Coverage also flags that virtual power plants are positioned to play a significant role in the coming decade, that device prices are rising in part because Artificial Intelligence is driving up demand for RAM, and a transplant feature notes the US waiting list is about 100,000 people long and recounts a case where a 57-year-old man lived two months with a pig heart.
