Article read and understood, thanks. I can't find anything in it relating to Norway's lack of military access, nor can I find anything elsewhere on the topic (brief search only as I'm only on my phone i'm afraid).

...if it's so difficult for devices to accept "high" voltages without frying, they should have just added a couple more cores to the cable and connector. 1 for 5V, 1 for 12V and one for 24V.
This is the problem where standards are made by companies who sell various "solutions" for problems which don't exist, and where these companies want to freeze out other suppliers.
That USB lead suddenly isn't just a wire with connectors at each end. Not for your benefit.
Re: If you want to prevent this..
It's so easy to design a PSU with over-current protection (in fact I would suggest that every commercial PSU has this anyway).
And it's so easy to design a charging circuit which takes a voltage, changes it to the one required and then controls the charge current to a battery.
Why anyone thought a device requesting a different voltage from a PSU was a good idea is beyond me, apart from obviously making the device slightly cheaper/thinner.
Having (say) a standard (fixed) 12V or 24V 5A-capable wall supply would be fine for most devices. The devices themselves could then convert this to whatever they need voltage-wise.
What is not mentioned here is the extreme costs the government and tv companies had to bear to produce the aether in the first place, not to mention all the modifications to keep pace with the advances in radio transmissions (tv, colour tv, stereo sound, surround sound, HD, 4k etc.).
It's not money for nothing they are asking for!
This looks totally awesome.
I cannot even imagine how much my productivity will be improved when I can sit at my desk and get my laptop to produce a virtual desk I can virtually sit at, while virtually typing on my virtual laptop.
Think of the further future; that virtual laptop could run a VR laptop of it's own, complete with a VR me typing on it. Multiply this up, and it will be like being in between two mirrors; millions of me, all typing! Think of the number of characters I could produce per keystroke!
