I would like to see a savvy caver reverse-engineer a crank-light
specifically designed to power a tiny LED headlamp as your 3rd source of
light.
Why does one need to reverse engineer it, David? Are you saying that the ones
available to date are not suitable - guess they're not hands free allowing
one to use ones hands to cave with, or not robust enough to cope with caving?
Cheers, Stefan

loved the ending monologue/rant. Hauling tanks back to the entrance on an
aborted dive trip in Honey Creek, thru seeming miles of sucking mud, I grumbled
to myself that I was going to take up knitting.
years later, I did. So there is still hope for the nettlebed explorers.
Time to close it down to all access, especially if cavers are involved.
Don't want them nasty ol' cavers spreading WNS!

This concept gave me an idea for a possibly more practical
application for cavers. Obviously we can't go caving while carrying a
flashlight in our hands, but one could perhaps design a helmet and/or
cave suit that captures both body heat (thermoelectric) and motion
(piezoelectric or
In the movie The Matrix, the machines use humans as a power source. This is
the beginning of the end for us.

I asked my best friend, a recently graduated electrical engineer that
created a thermoregulated charger for his final project, about his thoughts
on this idea and this was his response:
Energy density is too low. Even LEDs require a few hundred milliamps to
provide useful illumination. To get
