As the AI boom is ramping up demand for more powerful processors, Sustainable Metal Cloud, which operates “sustainable AI factories” made up of its HyperCubes in Singapore and Australia, said its platform reduces energy consumption by up to 50%, as compared to traditional air cooling technology typically used in data centers. The HyperCubes contain servers fitted with Nvidia processors, which are submerged in a synthetic oil called polyalphaolefin that draws heat away more efficiently than air.
