Charge your gadgets using a camp fire

They say you can use those panels to generate power..
And I dug a bit and found they turn radiant heat into current.
Doubt they'll be efficient, but a good idea for hickers..

The biolite uses the same principle.

Great find! The FlameStower is a clever piece of kit for off-grid adventures. The technology behind it is actually pretty neat — it uses a thermoelectric generator (TEG) that converts the temperature difference between the fire and the cool side of the device into electricity.
For those looking at alternatives, the BioLite CampStove is worth considering too — it lets you cook your meal AND charge your devices at the same time, so you're getting double the utility out of your campfire.
One thing to keep in mind is that these devices charge fairly slowly compared to a wall outlet, so it's best used for topping up rather than charging from zero. That said, in an emergency situation where you just need enough battery to make a call or check a map, it could genuinely be a lifesaver.
At $80 it's not a bad investment for serious campers or anyone building out an emergency kit. Anyone here actually tried one in the field?

I made a thermal generator once using a bunch of peltiers
