Finding electricity when there is a blackout

Neat power source when you're in the dark (better prepare ahead!)

Because what he is doing in this video, at least in Australia, is highly illegal.

The power running over the phone lines is used for signaling purposes, its not much power in the WattAmp sense, so wouldn't be enough to power anything other than a shitty LED.

Your power outlet however outputs a few thousand watts...enough to power a decent sized room heater.

This is generally illegal.

Like taking your Ipod car radio adapter and setting it up on a popular station. So that the cars next to you get that obnoxious song on your radio on their radio.

That is called frequency Hijacking, and is illegal.

However the signal that your little adapter is emitting, has to be more powerful than the signal that the radio station is emitting.

Its quiet fun, but I doubt you would get in to much trouble for it. Most of the time you only get static.

If you are interested in it, try it at home on your equipment.

This is the same way I found out how to Arp Spoof with ettercap, I have a partitioned LAN network at home I use for developing. I suggest you set one up too!

First of all, have you ever seen telephone wiring? It is 22ga at most. So drawing too much current you risk actually burning out some wiring. It is going to be a major pain if it is inside the wall (assuming your house doesn't burn down) and even more costly if the phone company has to come out and fix something from your house to the street.

Ok, so the local loop is about 20mA to 50mA fixed current and about 1kohm of loop resistance. All the phones used to be fully powered by the phone line, including some with glowing number keys. Modern cordless phones obviously need plugged into the wall because they use way more than a few mA. In fact, the charging of the batteries is way more then that.

You could probably steal enough power from the phone lines to run something like an LED lamp. Maybe even your iPod. But you are not using the phone line for the proper purposes and are definitely breaking some laws. Also in a power outage you could be dropping the local area phone line up to the transformers to a dangerously low level and making it hard for others to use the phone to do such things as call 9-1-1.

Buy some candles you freaks.

I don't know about other areas, but around here telephone lines are replaced by VoIP (over cable) and cellular sevices. I would say traditional phone lines will be obsolete in 5 years.... so hurry up to drain that free electricity!!
