Military Uses 'Bat-Hook' To Tap Power From Lines 282

Zothecula writes "As soldiers are fitted out with more and more electrical sytems to extend their capabilities, they become increasingly dependent on the power needed to run them. Since soldiers in the field don't always have ready access to an electrical outlet when they need to top up the batteries, the US Air Force has developed a device that taps directly into the electricity flowing through overhead power lines ... a kind of bat-hook for real-life superheroes."

I was a linesman/I&R guy for Telus, and I can attest to what you're saying. There is LOTS of old wiring out there, especially that 'licorice' stuff, it was the worst to work with. Nothing kills DSL like the dogs breakfast of Inside Wiring, Drop Wire and Telco Plant.

I think the difference is that DSL uses QAM where 1000BASE-T is using (correct me if I'm wrong) Manchester Bit Encoding (analog vs digital). I think that's where the speed difference comes into play.

With SAC boxes everywhere this isn't really a problem. The DSLAM justs gets pushed further and further out towards the customer. The real problem for Telco's will be line noise on aerial plant (due to induction, bridge-taps, and having to use clear caps). This will pretty much mean all telco's using VDSL-2 will have to be going to a dedicated count (bell-core) which means it's a good time to be a phone guy, cuz you'll be working lots :)
