ANDin the story “Reason” from 1941 science fiction author Isaac Asimov described a future where electricity was generated in space and then beamed to Earth1. It took engineers nearly three decades to describe a viable way to potentially launch such an orbital power plant. This week, nearly 50 years after that first engineering proposal and more than 80 years after the story, CalTech took a big step in making that science-fiction idea a reality: On Tuesday, its experimental solar-powered orbiting satellite was launched into orbit. The project is supported by over $100 million in donations from real estate billionaire Donald Bren.

This prototype satellite will be able to start its first tests in a few weeks. It consists of a modular test component that can be the basis for building larger solar power plants in orbit, 32 different types of photovoltaic cells to test which type is best suited for use in space, and a microwave array to test beam power to the Earth’s surface. If the technology is successful, it could help deal with one of the main limitations of solar energy: everything in orbit can be arranged so that it is rarely night. .

“No matter what happens, this prototype is a big step forward,” Ali Hajimiri, co-director of the project, said in a press release. space. There are still many risks, but going through the process has taught us valuable lessons. We believe that space experiments will provide us with a lot of additional useful information that will guide the project as it progresses.”

1 In this story, the robots that maintained this power plant also created a religion where they worshiped it, so keep an eye out for ChatGPT’s spiritual leanings as its training data grows to include information about the successful launch of the project.

Green transport update

Tesla got off to a great start in 2022, increasing production at the Shanghai plant and opening new Gigafactories in Berlin and Austin earlier this year. But as the months went by, things began to change, not least because of the ongoing chaos surrounding CEO Elon Musk’s purchase of Twitter. And the year 2023 does not look good so far. The world’s leading electric vehicle brand reported fourth-quarter delivery figures this week that fell short of analyst expectations, which have already been downgraded. With increasingly fierce competition in the electric vehicle market in both North America and China, Tesla’s stated goal of increasing sales by 50% per year seems increasingly implausible, even as overall sales of battery-powered cars and trucks grow globally .
