Here's the rules, FWIW. Pennies are only valid to 25c.
(2) A payment in coins referred to in subsection (1) is a legal tender for no more than the following amounts for the following denominations of coins:
(a) forty dollars if the denomination is two dollars or greater but does not exceed ten dollars;
(b) twenty-five dollars if the denomination is one dollar;
(c) ten dollars if the denomination is ten cents or greater but less than one dollar;
(d) five dollars if the denomination is five cents; and
(e) twenty-five cents if the denomination is one cent.
These ran NiCd cells. Here's some TL;DR from NASA about a variant of NiCd they use(d), not sure if it applies here.
Fancy NiCd, Higher density and sealed. They rely on precise chemistry to be hermetically sealed units (lean on one element, for limiting and only O2 production).
High pressure at full charge (~60PSI at room temp), higher if things go south, Pressure drops with charge state.
Excess discharge causes hydrogen production.
So, tin can, pressure changing with charge cycles (metal fatigue over many cycles?), H2 production, O2 production... maybe there is some chance for catastrophic failure there.
Though the units in question do have batteries, which have historically been of the NiCd variety, and are in this case as well. I'm not sure if any newer satellites use newer battery tech? (NiMH or some sort of lithium ion..).
they even try to steal live high-tension lines. which are aluminum around a steel core, nothing there but electrocution, folks.
Aluminium is 30+ cents a pound, that's enough to buy some glass. They'll have to steal 10x as much to make the same money, but...
Many do... but not Russia, which happens to be where the guy is.
It's thinned about 25-50% with naphtha so that it flows. "diluted bitumen".
LiFePO4 would be well suited to things like cordless tools and the like. iDrill?
There's no switching (or otherwise) power supply in a SD card though. Not much of anything other than flash and a controller.
I'd imagine more harmful to ingest/inhale uranium ore... in addition to radioactivity, uranium is also a heavy metal like lead. (in both senses of the term "heavy metal".)
However most ore is quite weak, with 1% being pretty decent... I think it's economical to mine it as low as 0.1%. A few mines in Canada are near 20%, though (which I suppose is related to Canada being the biggest producer... 1/5th the ore is end product, instead of 1/1000th!). Ore will often have lead and such in it as well (decay products), which is also toxic.
