Dear Crispin,and Nolbert
A TEG seems to be an expensive toy for UGANDA , on a cheap stove !
Solar cells will be cheaper!
Also a 3 watt cycle dynamo +rectifier + capacitor 5000 uF to get DC will do .
Feet powered dynamo 100 Watt 3000 rev/minute Gear box 75 X
.See army surplus for tube radio transmitters . 1950
Night/ day problem ! PRICE problem …..
HIGH POWER LED info ! measurement 3x3 mm
I tested a 5 WATT LED LAMP 230V AC with 9 LEDS in series . Price 5 €
It uses after power conversion 41 volt DC and 0,122 Amps .
1 power led : 4,56 Volt 0,122 Amps = 0,555 Watts
Regards
Frans

This is an interesting problem if the TEG-Powered stoves are now being used as direct power sources in Uganda. I will talk to the circles here to see how the extend of this development.
We have a social gathering organized by the Uganda National Alliance on Clean Cooking (UNACC) called Baraza <https://www.facebook.com/unaccbarazas/> this evening and I will try to inquire from some people in the cookstove sector.
Like I like to say; when you create One solution, you in-turn develop another THREE problems!!!
