Charging devices while hiking
As some may know,I like to go camping from time to time.
Now,a problem I suffer while hiking out on the hills is my devices keep running out of power.
Im going to be undertaking a project to solve this problem,All my devices obviously need electricity,I've have used spare batteries,power banks etc to try and keep them running but sooner or later they all run out.Solar chargers are a waste of time and money in my opinion when you need sun most itīs either raining or other circumstances that makes it impossible to charge with them (even in a sunny day it takes too long to charge and input that charge into my devices)....Batteries are good but very encumbering. I have looked for alternatives but they are either too expensive or far too large to carry around.
One thing that I always have with me,even on the longest treks is fire in some form or other so with that in mind, I've been fascinated by the idea of producing electric from a camp fire.I know, the efficiency will probably be poor but its possible.
So, with inspiration from a project I seen on YouTube using T.E.Gs (Thermoelectrical generators ) I'm thinking of building a 'cheap' teg charger.
My main goal is to produce a 5v usb from a (self cooling) gadget.Ive ordered the generators from eBay and was wondering if anyone has any experience or advice on this issue?
