What a ruddy good idea,thanks for that
I've also ordered a few 0.9v-5v to 5v usb step up modules so in theory I only need to create a couple of volts and the module should do the rest and stablise the current to 5v (I think/hope)
I was thinking of using hot water boiled on the campfire and normal air temperature water out of my water bottle (difference of approx 70+ degrees) to create a current using them T.E.G things.
