This is a serious question that I need to find an answer to. As most of you know I live off grid, no PG&E available (and at $40,000.00 just to connect... will never be available on our property) and I have a nice solar array and battery set up that is working great. BUT we are now moving into the winter months which as we all know means shorter days (less time to recharge via sun) and cloudy days (really screwed on production!). So I have been looking at various ideas for power generation using what I have readily available or at least affordable to procure and install. Wind is a great alternative where I live... but that's an additional $2,000.00 - 2,500.00 I don't have and that's a conservative estimate. Anyhow we just installed a wood stove in our cabin (removing the propane heater we had... hallelujah for that!!!) and as I was finishing the brick work for thermal retention and radiation... I thought, there has to be a way to produce power when I am burning wood. And lo and behold this thread appeared today --> http://glocktalk.com/forums/showthread.php?t=1448153 So that started me on a path of looking about and this is what I found: http://www.shop.customthermoelectri...-Power-Generation-Module-1261G-7L31-24CX1.htm So my question is this, according to my math (which sucks most times) if I get 8 of these and wire them in series I should be able to produce a theoretical 31.2V @ 4.9A @ 152.8W of power, which I could then run through a charge controller to keep my batteries charged during the cold nights and short days. So with the stove running at peak heating capacity say for 5 hours of the day, I would be able to produce 764wH at 24.5AH of DC power that could be put back into my battery array. Is my math right based on the specs in the link? And do you think I can do this, in other words do you think it will work? I really hope so, because it would mean I could build a thermal power plant for less than half of a wind turbine and that I could control operations at my will instead of relying on mother nature. I have at my disposal 77 acres of land with plenty of wood for fuel (hell the wind knocks enough crap down from the trees that I don't even need to run a chain saw! And I could very easily build a barrel stove outside to do the same thing... Well?
