Should have gone to school?

They have a probe to bond the copter to the wire before the man gets killed by the current going through him. The current arcs across several inches as the probe is attached.

Just what voltage do you suppose that fence is running at? (its purpose being to discourage livestock from touching it, not toast it from a yard away!)

(I now have a mental image if a Frankenstein's laboratory style electrical setup, with electrical arcs climbing jacob's ladders etc)

[Graham.]

Yes, I am sure that is right, just as vehicles and aircraft build up a charge, or us walking on a nylon carpet and touching an electrically floating metal handrail (which illustrates the point rather nicely.

Oh dear, have they still not that anomaly sorted out?

What I don't think is always helpful, is to think of "static" electricity as somehow a different phenomenon to "ordinary" electric. Is that how it is still presented in schools?

Its early morning on the plain, and two vultures awake. The younger one says

"I am going to go find me some blood. You coming?".

The older wiser bird says

"Na, you go, I am going to soak up the early morning sun for a bit, anyway I doubt there are any good kills laying about for us yet".

So the young bird flies off by himself. After ten minutes he returns, and to the wiser birds amazement he it absolutely covered it blood. Its all over his feathers and literally dripping off his beak.

"Wow, said the bird on the tree, you must have found something *big"... "what was it... a cow?"

"Na", says the bird...

"a buffalo?"

"Nope"

The bloodied bird says

"come with me and see".

So they both fly off together. After five minutes of flying the young bid says

"You see that big old oak tree down there?".

The old bid excitedly says

"Yes, yes...".

The young bird replies

"Well I didn't!"

Sorry John, I was posting in the middle of the night from my crippleberry. I thought we were still talking about super-grid lines. A spark must jump between the approaching object and the wire.

Have not been into a school of any sort in many years. :-)

Absolutely agree about static versus, umm, dynamic (?) electricity. Teaching did seem to make them seem like different beasts.

[John Rumm]

Easily done...

Still it could make for a good "you were only supposed to blow the bloody doors off" moment, when testing the new electric fence, if a small quadruped touches it and then bursts into flames ;-)

(not so good for the critter mind you!)

Must be that metal wired suit they use then;!?..

Bilge!

Birds hate power lines because you can see their bottoms. Pylons are high so no tweety birds.

Trees & bushes are lower so there are more tweety birds.

Now get to ground level and we have ducks, geese, chickens and all the rest of the more sensetive avian society

How many people have flashed their naughty bits on pylons?

But handy if you like ready roasted rabbit.
