Why doesn't everything use solid aluminium capacitors?

Nothing wrong with real electrolytic capacitors. Anything can be made
cheaply.


Yep, Good caps were made by Cornell Dubilier, Used them for many years.

I remember Sprague Compulytic, not sure how good they were, never had
one fail though. Still got some (twice the size of a fist) in a drawer.

If the seals are good, why wouldn't they work ?

They might need to be re-formed.

I'll duck down behind this desk, while you give
that a try.

https://en.wikipedia.org/wiki/Electrolytic_capacitor

"Applying a positive voltage to a "wet" capacitor causes a
reforming (self-healing) process which repairs all weakened
dielectric layers, and the leakage current remain at a low level.[73]
"

Another web page I found, has a method.

https://www.6v6.co.uk/vcomp/tech_tips/reform_caps.htm

"Electrolytic capacitors can be dangerous. They can be charged
to a high voltage and will retain that energy for quite a while.
If the terminals of associated circuitry are touched, a severe
shock and burn may result."

I think Captain Obvious wrote that paragraph.

There are plenty of things to know about this
topic, to remain safe. With his wealth of bad
capacitor experiences, I'm sure the Commander
knows what I'm talking about. Personally, I find
the bad experiences are the best teachers.

They do, I've used a few of them. The worst that could happen is some leakage.

You would have ducked even further when I reformed a NiCad battery in a laptop by over-volting it.

Didn't we all use capacitors as kids to shock people or to cause explosions by overloading them?

Did you ever misuse a CO2 fire extinguisher? There are two fun things you can do with those. Freezing people's body parts, and dropping them off very high buildings causing them to rupture and explode catastrophically.

No. I have never abused life-saving equipment.

You should NEVER drop people's body parts off very high buildings? :-P

They save the lives of those stupid enough to have set light to stuff. Anyway, it was in a disused granary.

****ing wasteful. Everybody knows the best use of a CO2 fire
extinguisher in chilling beer. You're excused from knowing that as you
Brits prefer to lap it up warm and still.

Ah, the question mark! So you probably think it's "nicer" to
kill them by neglect?
You have personal experience? Tell us ALL about it. Maybe not
in this thread. Look at the subject line. Look at the groups this was
cross-posted to.
WTF are you phishing for this time?
