Joule Thief in between Peltier/TEG and DC Motor?
As per the title I've got a Peltier cooler chip sandwiched between 2 heat sinks acting as a Thermoelectric generator (TEG) which when sat on my wood burning stove generates about .5V (which is a bit disappointing). The idea was to cheaply recreate one of the EcoFans, so the plan was to connect the TEG to a low voltage DC motor. The obvious issue is the low output from the TEG itself - I need to maximise the heat dissipation from the top heatsink to create the temperature difference, but even solving that I'm going to struggle to consistently get more the 1V from the TEG.
Before I go to the hassle of sourcing and making a Joule Thief (like the 1up instructable
) is there something fundamental I've missed that means either the TEG won't work with the JT, or a 1.5V - 3V DC motor won't work with the JT?
Appreciate any help is establishing the feasibility of this idea, or suggestions to an alternative solution :-)
