What a coincidence Bob. I have just carried out a similar experiment to
the 'mains noise' one. With everyone furlowed at home in the UK I
wondered if we would run out of electricity.
I decided to start stockpiling electrons. I didn't want to alert others
before I'd hoarded enough of them, and there is no room left in my
double-garage for batteries, thanks to the mountain of toilet rolls and
hand sanitiser that I already have.
I hit on the idea of a massive leclanche cell. The disused septic tank
in my back garden is made from aluminium (that is the UK version of
USA's alooomynum) so if I set fire to a telegraph pole to get a carbon
anode, all I needed was a few hundred gallons of ammonium chloride.
Well, that last part took a while, and the local 'curtain twitchers'
were intrigued when the tanker arrived. I quickly covered up the large
'HazChem' logo to avoid any hysteria and pumped it all into the waiting
septic tank.
I used lengths of steel scaffold poles to form connections back to the
mains supply. I needed to get my stash of electrons down in the ground
as fast as possible, before everyone else started doing it.
The fuses in the consumer unit would be limiting though, so I bypassed
the whole thing. I even bypassed the 100amp emergency fuse upstream of
my consumer unit. The huge spark as I moved the final scaffold pole into
contact was quite exciting, and the really loud buzzing noise was
impressive too.
A quick look into my septic tank showed the electrolyte to be boiling
furiously. Everything was going well. All the neighbours were out in the
street moaning that the mains seemed to have been cut off, but by the
time they figured out why I'd have MY stash of electrons, so hah!
It was about this time when I realised the scaffold poles were starting
to glow, but then I was distracted by the huge explosion at the small
sub-station about 100 yards away.
A 2-tonne transformer made it up to about 300ft, before remembering
about gravity. While the neighbours gathered around the impressive
crater it made in the road I was distracted because the glowing scaffold
poles had ignited my stash of toilet rolls.
Fortunately the smoke from the resulting fire concealed me stacking the
scaffold poles back in a neat pile when the police arrived. I still have
my secret stash of electrons available once things quieten down, but
I'll have to start hoarding toilet paper again :-(

I don't necessarily agree. Anyhow, try to remain sane during the pandemic thing. Don't touch anything, don't talk to anyone, don't go anywhere...wash your hands at the top and bottom of the hour and for goodness sake wear a mask, gloves, ear plugs and safety goggles.
