The computing hardware is packed inside a watertight storage module and together weighs 1,300 tons. The module is being submerged about 115 feet (35 m) under the water, a process that takes about three hours. Although work on installing the first module has begun, Highlander has ambitious plans to install 100 such modules at the site and build a capacity of nearly six million computers working at a time. Such a staggering number of computers will also generate a lot of heat which will be naturally cooled by the surrounding sea water. This alone is expected to save 122 million kilowatt-hours of electricity that would have otherwise been spent on cooling if the facility were located on land.
Additionally, the facility, which is expected to be in place by 2025, will also save 732,000 square feet (68,000 square meters) of terrestrial land that can be used for other purposes and 105,000 tons of fresh water, which would be used for cooling efforts. The modules have been built to last 25 years, but a lot remains unknown about how the construction will be impacted by corrosive seawater and underwater ecosystems. Highlander’s experience in setting these centers up is fairly limited to the tests it carried out in January of 2021 in the Guangdong port of Zhuhai.
