German-Japanese researchers invent electricity-free tech that could cool datacenters

Datacenter cooling could get a lot more affordable, and sustainable, if a joint German-Japanese research project can be scaled beyond the laboratory. Researchers from the Karlsruhe Institute of Technology and the University of Tsukuba published a paper in Nature Energy on Friday discussing the success they had with a solid-state cooling technology that doesn’t need any electric input at all, and was still able to demonstrate temperature reductions in laboratory experiments. For those unfam
