Computer scientists at the University of California, San Diego, working in collaboration with Google, plan to deploy a rather unusual compute cluster built not from conventional servers, but using 2,000 retired phones.

The goal is to demonstrate how these devices might continue to serve as a low-cost, low-carbon computing platform after their original owners have abandoned them for a shiny new widget to doomscroll TikTok on.

“The project was the brainchild of Jennifer Switzer, a former PhD student at UCSD who is now working on a post-doc at Google,” Ryan Kastner, an associate professor of computer science at UCSD, told El Reg.

In particular, UCSD will be using 2,000 Pixel...
