What do you guys think of this video? Some guys attract lightning to a wire.
ScottH, Mon May 15 2017, 03:33PMThey use the anode of a flyback to charge the wire attached to a kite. Here is the video
Was this an actual lightning discharge, or some other phenomenon?

Everyone knows Benjamin Franklin's famous experiment in 1752 where he flew a kite into a thunderstorm, and drew sparks from a key hooked up to a Leyden Jar (a capacitor) tied at his end of a silk kite line.
Several people who have tried to copy the great man's experiment have been electrocuted.

The bottle was not a Leyden jar, but a makeshift spool for the wire. How does the relatively small voltage (10s kv+ and milliamps) of a flyback trigger a 100mv lightning bolt from the storm?
Do you think the flyback hooked up to the wire had any effect on attracting the bolt?

I don't know, Scott - if the video is genuine, perhaps the flyback voltage had the effect of pre-ionisation around the wire, as used in some triggered spark gaps.

Probably coincidence, a simple kite in a storm will eventually get hit.

The television does in fact contain a high voltage capacitor very similar indeed to a Leyden Jar. The mu-metal shielding plated onto the glass is designed to function as a capacitor, and is used as such in the HV voltage multipliers in many television designs of that vintage.

I did wonder if a TV tube could be repurposed as HV storage. Turns out that it can, but the ESR makes it almost useless. A typical CRT can take around 3* its normal EHT voltage but this risks it imploding.

I would suggest that if you hooked up a kite tethered by a wire strong enough not to break
the coronal loading up the wire would not be supported by the small flyback which also sweeps
the beam and lights up the tube face. Yet the TV on the you tube was working.
Having said that, I have flown the hydrogen balloons on the end of the aerial lead on a Gibson Girl
transmitter, It works just dandy.
I also have written up insurance report for a big TV destroyed by a lightning hit
on the aerial.
