That, and at lower temperatures, I'd think they are less likely to have
"accidents".

Point being to let me see what's going on, and to contain things for a few
10's of seconds till I can put the extinguisher into use.

Maybe this is what I can use my old dishwasher for.  Although I'm

It do in NIMH, and I'm sure Li-whatever is more delicate.

Everybody wants TONS of energy in a little bitty can.  Things are likely to
get even more interesting..

I've seen a lot of fuel cells under development for laptops, but since
you'll never get one on a plane, I think the primary market is locked out.
