Too lazy to search. But there is a story out there of a guy who was wearing rubber soles, and the lightning went in his head and out his *******.

Rubber soles don't do dick in a lightening strike.
We call that type of scarring a "fern pattern".

I think it's beautiful. Does it look like that years after, or are these shortly after the strike?

My neighbors car got struck last year. Popped all four tires, burned 1" wide holes through the pavement at every rim. It was pretty crazy.

^DAMN that's insane! So would that have been safe to be in? Since the current would travel through the body of the vehicle, around occupants?

Not doubting the ******* exit wound. I'm just saying that rubber soles don't make any difference.
Thumpetto, it is safe to be in a vehicle in a storm or in the case of downed wires because of Faraday shielding.

Read article. Lightening struck house. She was brushing teeth. Rubber soles kept it from going out her feet.

Again, I'm not doubting the lightning exited her *******, especially if she was inside and the structure lessened the strike.
I am saying that if you are directly struck by lightening, rubber soles will not help you.

The person who wrote the article clearly wasn't a physicist or an electrical engineer. ******* or no *******, that lightning streaked across miles of air with a potential of over a hundred megavolts on its way down* to her. A few millimeters of rubber at the very end of the trip are utterly insignificant. Whatever was behind her **** simply happened to be slightly more conductive than her legs.

* Yes, down. While the initiating stroke does travel upwards, it is the return stroke which conveys the majority of the energy and produces the visible flash.

A sense of perspective is called for here.

Lightning is powerful. Amazingly powerful. Really, mind-blowingly, immensely powerful. Hundreds of megavolts.

Mankind simply does not possess materials capable of functioning at those levels. You know those high-voltage overhead power lines you see running massive distances across the plains? The most powerful of them run at only a few hundred thousand volts, and those have ceramic insulators several meters long suspending the cable from the mast.

Lightning is several orders of magnitude more powerful than that.

A bolt of lightning which has already traveled through miles of one of the better insulators known to man (air) isn't even going to notice an inch of rubber, or a foot of rubber, or a block of rubber larger than Hustler's ego. You simply cannot insulate against lightning. All you can do is redirect it around the things you wish to protect, by providing it with a more ideal path. This is why people in cars survive lightning strikes. It has nothing to do with the rubber tires, and everything to do with the metal body of the car offering the lightning a more attractive path than through the meat inside.

ie. Faraday shield, or cage if you prefer.

Just a reminder of how powerful like lightning is:

^damn

how do you imagine the lightning passed through them all? Kind of spread out in different fingers like tree roots because of the metal ring?

One downside to a carbon fiber supercar? Or is CF still conductive enough to do this?

I started wondering about that while writing the last response.

Lightning strikes all sorts of interesting things from time to time.

Airplane strikes in flight are pretty common (according to this source, every single airplane in the US commercial fleet is struck an average of once per year), and there is some concern about the growing use of composite airframe materials in this context.

The Apollo 12 spacecraft (complete stack including Saturn V rocket) was struck by lightning twice, 36 and 52 seconds after liftoff, and provided what may be the coolest picture ever to come out of the US space program:





But I couldn't find any data at all about what happens when lightning strikes something like a Corvette convertible or a Zenvo ST1. If history is any indicator, the Zenvo is quite likely to burst into flame and kill you just from normal driving around, but what about the Corvette? My suspicion is that the metal in the windshield frame would probably be sufficient to act as a lightning rod, though I'm going to abstain from gathering empirical evidence to support this.


I'm wondering more about medieval knights in full armor on horseback right now.
