[Retired Phones Build Low-Carbon Cloud: Google Plans to Use 2,000 Old Pixels to Provide the Computing Power of 50 Servers] According to Deep Tide TechFlow, on June 14, Google is exploring a low-carbon cloud computing solution based on repurposing old hardware. The plan involves reintegrating approximately 2,000 retired Pixel phones to construct a distributed computing cluster equivalent to the scale of about 50 servers, aimed at handling specific types of lightweight computing tasks. This solution redistributes the idle computing power of mobile devices into a cloud computing network to reduce reliance on high-power servers in data centers, thereby lowering overall energy consumption and carbon emissions. Industry experts believe that if this "edge devices + distributed computing power" model is implemented on a large scale, it could provide a lower-cost, energy-efficient supplementary path for cloud computing infrastructure. However, challenges remain in terms of stability, scheduling efficiency, and long-term maintenance.
