Fellow ham,

A post from LA4RT has made me realize that "Human powered" power
generation is too narrow a scope for this discussion, so I'm starting a
new thread.

Let's hear ideas about alternative sources of power for radios: we might
be unable to find steam-driven units ;-) but there's always more that
one way to skin a cat.


WW2 portable steam chargers are still available, they come in a small
crate which can be airdropped.

Military Radio Battery Charging Set

These units saw widespread use in remote locations, all you need is some
water and some wood. Not cheap though, they are now a collectors item
selling for around 2500 UK Pounds. ( US$ 5000 ).
