Rick C may have his problems, but he isn't a troll. The fact that John Doe doesn't like him might be evidence in his favour, but John Doe is such total disaster that his opinions can only be discarded.

The funny thing is Bill is definitely a troll. His entire reason for being here is not to learn or to even discuss issues. He likes to discuss issues because he knows some folks here will argue adamantly and typically incorrectly giving him the opportunity to correct them.

Don't get me wrong. I've learned a lot from Bill. He will dig into a topic in depth even if he presents somewhat biased facts from time to time or even misinterpret the few facts uncovered. Still though, it can often be educational reading what he posts.

Sometimes entertaining too.

John Doe doesn't actually understand what a troll is, or anything else either.

He'd probably waste less bandwidth if he was a little better informed.

He wouldn't have to learn much to be better informed, but the prospect of him ever learning anything is remote.

There is another type of atomic battery, namely the direct collection
of betas in a vacuum. It makes small currents at hundreds of
kilovolts, which can be hard to use efficiently.

With enough 1950s radium watch-hands, *anything* is possible.

I prefer the plastic filled with doped strontium aluminate - just
needs to be in the sun for a few hours to work all night. 3M had
an emergency torch that used it to great effect just before power
LEDs became common.

I tried that, but there's not enough daylight in that bedroom to
charge the strontium aluminate. Strontium aluminate is amazing
stuff.

Strontium-90 is dangerous because it replaces calcium in vivo.

This is a compound of ordinary natural non-radioactive strontium with
amazing ability to absorb photons and re-emit them later. It makes the
old glow in the dark toys look like - well toys. If I leave my find in
the dark torch in the sun it will allow you to see by it after dark once
dark adapted without having to switch it on!

A modest sheet of that stuff could be left outdoors in sunlight, in
some village without electricity. It would immuminate the indoors for
hours after dark, enough probably for a kid to read a schoolbook by.

It must be 200x better than the old zinc sulfide stuff.

This glows in the dark, for a minute or so.

P7 radar phosphor.

I've noted some fluorescent lights will glow for hours after removing
power.
Or was that caused by the radar from the airport tower 4500 ft from my
bedroom when I was 13 yrs old. At least that was a thought I had then.

An airport radar sweeps, so would make a flash of light every second
or two.
