Yes - my mistake. Tesla AC; Edison DC. Goof up - sorry.
Regarding DC, I've heard that some research labs are actively advocating it, since the losses are said to be low. Hope this is not another goof up

If that's the case (researchers advocating it) I guess there's some constraint to it that you didn't mention. In general AC is the better form of current to transfer electrical power: AC is required to transform voltage up or down. Electrical Power P = U (Voltage) * I (Current) => Higher voltage allows lower current for the same power. Loss occurs due to resistance (which every conductor (=power line) has) and increases with higher current. That's why landlines have high voltage and before reaching your house it's transformed into lower voltage. Mr. Tesla apparently realized that better than the honorable Mr. Edison

DC transmission makes sense for transmitting over very long distances at extremely high voltages - like 750,000 Volts. DC transmission has far less corona on the wires at these voltages - and hence lower interference with radio signals. For very long distances there is another factor: If the transmission line length starts to approach one quarter wave length of the AC frequency (somewhere over 1,000 KM for 60Hz), weird things start to happen: An open circuit at the far end appears to be a dead short at the generator end - not good. So DC transmission over long distances offer these advantages: (a) Higher possible voltages - lower currents - less copper losses. (b) Lower interference transmission due to corona. (c) No constraint on the maximum length of a transmission line.
High voltage DC power transmission is nothing new, but I haven't seen it yet in the USA.

Thank you for educating me So I guess these benefits make up for the need for DC-AC-inversion?

Yes, there is a cut-off between AC and DC. Above a certain distance it becomes economical to go DC.

...going flat too quickly.
In 1920, only 10% of Uk homes had any electricity. And most of those that did, had only lighting.
In 1944, 2/3rds of UK homes had mains electricity - one light per room, and one wall socket per two rooms.
100 years ago - not that long, really: you should expect to live pretty much that long now - you couldn't have charged the iPhone in the first place!

Not that many years ago if you had to get a hold of someone in an emergency you had to beep them. Kids won't even know what I'm talking about.

Kinda like a pager, I presume.

A guy here had his phone play Justin Beiber yesterday, full volume, courtesy of his little brother, who is now grounded for a year for pulling pranks like this and getting grounded over and over and over and over and...
Basically, the little brother is crazy (as he LIKES Beiber!)
Last Friday someone hacked the school's PA system and forced it to play Justin Beiber nonstop. (Most professors stopped classes and had students leave the building). The techs finally had to kill main power to the system to shut it off.
AFAIK, the person (apparently a student) was identified and suspended for the incident, and may face criminal hacking charges (and, according to what I heard, 'Aural Terrorism' Charges as well).

Instead of water boarding and the usual torture techniques I think this young man/woman may have stumbled on a more severe and and lasting form of torture. Imagine having to listen to him for more than a brief period. I shudder at the possibility!

I've only carried a beeper and few times and the only time I carried a beeper in a programmers position I told the company that as long as it was turned on they payed me. They didn't like it but they payed.

That's a point: if people could write telegrams without the awful netspeak, why is it needed now?

Compare the average cell phone's battery life from the mid-90s with an iPhone's, then we can talk.
I'll grant you that this is comparing apples to oranges, but so are you...

My previous phone was ten years old when I retired it, and it still had a three week battery life!
And it fitted in a shirt pocket before you ask
