In this video I show you how to make a stove top ecofan (mostly from junk) that's way more durable than conventional ones. It uses a theromelectric generator (TEG) module, like others, but contains a fix for the problem of TEG failure.
Usually people let their stoves overheat from time to time. This cooks the TEGs and means they don't last very long. If you make a DIY fan the way I show, you will have overheating protection!
This is still something of a prototype in testing, but results so far are excellent.
An automotive wax thermostat: ebay $7 - https://goo.gl/iPkoQi or uk £5 https://goo.gl/gLiUn4. An old chainsaw cylinder, ideally at least 48mm (1.9") bore. Scavenge one - you know you can :) The hot side riser block: any old CPU cooler (the simple lump of aluminium extrusion type is best - no heat pipes etc. needed) The TEG : the design here uses two, you can get very cheap ones that are actually TECs branded as TEGs (most of the ones here https://goo.gl/rczuD9 on ebay are like that). Or get ones like this: https://goo.gl/nsxCwS which are still quite cheap but much better in terms of power output and heat resistance. Old brass compression fitting: Scavenges some or ebay (https://goo.gl/U7XFv6).
