This talk of camping in adverse weather has reminded me of last summer when we stopped off at Eguisheim (near Colmar) in the French Alsace wine region on a campsite on the road up to the castle overlooking the town. (was that only a year ago ?)
One night we were treated to one of the spectacular thunder storms that are typical of the area. I remember them well from when I lived in the Rhine Valley and it is which is why many houses in there have lightning conductors.
There was almost continuous sheet lightning and rumbling of thunder which lasted for several hours. I was happy to sleep up top and look at the spectacular display while I drifted in and out of sleep......
Many of us will have seen the Top Gear episode where Richard Hammond is in a car that is subjected to a discharge of many millions of volts of electricity equivalent to a lightning strike.
It’s schoolboy (and girl!) physics demonstration of the principle of a Faraday cage. In essence the current passes through the conductor on the outside (i.e.the car) and nothing gets in. [My physics teacher would be pernickety about this explanation but he wont be reading this!]
I am comfortable so far, but cars are usually metal. What happens in a fibreglass campervan which is a relatively poor conductor, or worse still a fibreglass pop up top with canvas sides and a couple of metal struts either side propping it up ?
Ah, you might say, it’s wet and water is a good conductor. In my case at least the van and pop up roof was relatively dry while the thunder rumbled overhead.
Are there any instances of fibreglass motorhomes or campervans with pop up roofs being struck by lightning?
If not, perhaps it’s time for another Top Gear test possibly with a vote on who should be the guinea pig this time?
Having been uncomfortably close to lightning strikes a couple of times I am not volunteering!
