It took 25 long years, but 52-year-old Xie Kefeng was finally reunited with his son, who had been snatched as a baby. The power of technology,     1    (specific)a facial comparison algorithm played a major role in bringing about the happy outcome.

In 1998, Xie’s wife stepped out of home to buy groceries, leaving their three-month-old second son, Xie Qingshuai, on the bed     2     the door unlocked. When she returned 10 minutes later, the child     3    (disappear). The couple reported the incident to the police, but the child could not be found.

8 . In an era where data centers are becoming increasingly vital for our digital society, China has begun a groundbreaking endeavor to push the boundaries of innovation and sustainability.

Nestled off the coast of Sanya, Hainan province, China is in the process of constructing the world’s first commercial underwater data center. This project aims to revolutionize the industry by using the power of the ocean depths while saving a significant amount of energy and land. With the potential to equal the computational (计算的) abilities of about 6 million conventional personal computers, this underwater data center is bound to be a game-changer.

The data center modules (模块) of China’s underwater facility are being carefully installed on the seafloor at depths of around 35 meters. Designed to withstand the harsh underwater conditions, these modules are expected to operate sustainably for up to 25 years. Each watertight storage module weighs an impressive 1,300 tons and boasts the capability to process over 4 million high-definition images every 30 seconds. When combined, the entire facility is projected to match the computational power of surprising 6 million conventional PCs working together.

The construction of the underwater data center is a result of collaboration between Sanya officials and several Chinese tech firms. With the initial deployment of one storage module in April and the recent addition of a second module, the project is well underway. The ambitious plan aims to have a total of 100 modules fully operational by 2025, marking a significant milestone in sustainable data center development.

The motivation behind this pioneering project extends beyond technological advancement. By choosing an underwater data center, China is actively addressing the challenges of land conservation. Traditional data centers can occupy vast amounts of land, often equal to the size of multiple soccer fields. In contrast, this underwater marvel takes up minimal dry space, preserving land for other essential purposes. Additionally, the use of natural seawater cooling reduces the strain on traditional energy sources, leading to a significant reduction in carbon emissions. This environmentally conscious approach agree with global sustainability goals and sets an example for the industry to follow.
