DC backbones

But would require huge copper busbars to run across the data centre, in order to handle the high current. The cost of the copper - and the size of the busbars - outweighs the benefits of direct DC (48V) connections over 240Vac with local PSUs. A high performance PSU (or two for resilience...) per rack may make sense, though.
