Ecofan mods

.1 amp and 1.5 volts comes to only .15 watts. This is a very small fan.

The resistor would be dissipating .1 amp x 10.5 volts = 1.05 watts, 7 times the wattage of the fan. Not a very efficient use of the TEG output.

Maybe a series/parallel arrangement of L.E.D.'s could be used to drop the voltage to the fan and provide light at the same time.

The .1 amps was just to show how to calculate.
The L.E.D. idea is good if he can calculate how to do it.

That's a great idea, I will do that.

You should look into a homemade wind turbine. Carve out a blade, balance, get a small permanent magnet motor as the generator, top a tree, some wire. Lots of fun.

That would be an option, but we go for months with very little wind here.

Are there any springs up a hill near? Thinking water power.
Perhaps more solar panels are what is needed. I know that you are way north of me.
I set up three 200watt 40 volt panels in series (120v) that feed into a Outback Flex Max 80 charge controller.
The controller outputs a high current into a 12,24,36,48,or 60 volt battery bank. In my case a large 12v bank.
I have seen very good outputs in November, cool but sunny, just low sun and short times.
200 watt panels were $180.00 Canadian plus tax.
Lake Huron keeps us cloudy.
