Telco gear tends to be 48VDC all over the place. It just works. Speaking as a guy working at a telco in the IT department, I'm hugely in favor of moving to 48VDC servers.

It "just works" because you have a huge battery 'stack' somewhere - very filthy and dangerous lead-acid stuff.

Also, a TNV power distribution system is not necessarily any more safe than AC mains power at overvoltage cat I or II.

I don't run a datacenter, but I sure would like to get rid of the power bricks that all small electronic appliances seem to come with these days!

probably because these 'wall-warts' are linear converters - seldom better than 40% eff.

As more stuff conforms to the ENERGY INDEPENDENCE AND SECURITY ACT OF 2007, these will become much less of an issue.

"the case of ODF and OOXML illustrates how their significance isn't all that it used to be." => Non Plus - I have worked with various IEC/ISO WGs and TCs; and the ODF debacle does not seem to be representative. E.G., I consider ISO17025 and ISO9899:1999(cor1) to be relevant, usable, and reasonable.
