Well yeah, they need something to keep them busy after selling most of their hardware department to Lenovo
The direct cooling technology the HCPVT systems uses is "inspired by the hierarchical branched blood supply system of the human body and has been tested by IBM scientists in high performance computers, including the Aquasar supercomputer and SuperMUC, IBM said. Those computers use water to absorb heat from the processor chips, which is then used heat the facilities.
Makes sense, I heard computer cooling (think of supercomputers, also datacentres) is a pretty interesting engineering challenge nowadays. Good to see IBM sharing their knowledge on the subject
