Free electric from BT
ok not that i would ever do this but. . . .
what sort of power would you be able to get from a BT phone line.
ac.dc
voltage
current
would there be enough to charge up some 12v batterys for LED lighting ?

internet says 50v DC usually with 80-90AC overlaid on that when it is receiving a signal.
I'd be interested to see how you could make that usuable without breaking something 
also if you come across this: http://www.phone4energy.com/ it is almost definitely a scam.

48V DC while inactive with 2k or 4k of resistance in the line. If you draw more than a few mA then the line activates as if you'd picked up the
receiver so you can't get much power out of the line.

Every daft/crazy idea ever thought of, has already been cast out of cheap plastic in China, then had LEDs stuck on it and sold on eBay

You might get a knock on the door when BT notices your permanently activated line. And then a slap on the wrist.
