[Elecraft] Portable power, hydrogen fuel cell

[Bob]

It looks like these refillable "cores" hold the equivalent of 33 watt-hours
of power.  That's maybe 40% more power than the internal AA battery pack
holds.  The internal battery pack weighs ~240 grams, about the same as the
"reactor" and a single core.  So it seems like a fair trade in terms of
energy/mass.

A 5 watt solar panel weighs 170 grams, and during an average day will
produce 20-40 watt hours of power.  I might be more tempted to carry one of
those around for "limitless" power as it costs much less and is less
complicated.

But the technology is interesting, and in its infancy, so it will be
interesting to see where it winds up a decade from now.
