4K works today over the Internet. At the current moment its the only way to get content!

It doesn't stream real time granted, but if you can schedule the download you can have a movie in a reasonable time with a decent connection.

We are still lacking available 4K content, and scads of people still can't see the difference with 1920x1080 though. Back 6-9 months ago I scoffed at the idea of 4K, but if I were buying a TV today, I wouldn't consider a non-4K model. I think this will become a thing.

Course more then a TV I REALLY want a 4K computer monitor, then perhaps I could see all of an image out of my digital camera!
 
URD Underground power feeds--drive or walk the area where you live-the underground feed goes to a pole riser somewhere.It is not possible to bury them all.And above medium voltage distribution-just becomes too expensive.It can be done--but VERY costly.SF6 transmission lines are often required-and there is still the utility company owenrship of the property ABOVE those lines.This is so they can have ready access to them.And these SF6 gas filled lines require special substation equipment.And also the utility owns those properties above the underground lines in those cases in order to prevent "backhoe" fade-imagine the startled-and possibly DEAD backhoe operator if he hits a 33/69Kv SF6 uderground line!!!!
 
Did someone mention SF6???

At risk of completely hijacking the thread, Though part of this IS communication based......
I had completely forgotten about SF6 (Sulphur HexaFluoride for any non-techies) (note the U.K. spelling ;-) )until Tolivac mentioned it. Way back in the '70s/'80s/'90s the U.K. had (as well as the microwave 'Post Office Towers') a 'spine' system involving an 18-tube co-axial cable, insulated with SF6, running 9 tubes in each direction at '60MHz'. All very expensive to maintain, and rendered 'obsolete' by satellite technology.

There is also (local to me) a 132kV underground power distribution line, which runs for 2-3 miles, installed at great expense because the local provider couldn't get 'planning permission' for overhead pylons. Sadly, I have no idea whether it's 1-phase, 3-phase, or even DC, I have never been able to find out any details... :-(

Hope this is of some interest to some of our members!!

All best
