   This is quite impressive!
   I’m thinking of building another type of energy source, based on the chimney-effect and thermal ventillation. Basically a tall black tube with free top and bottom, and a few fans inside which would produce electricity from the wind venting upwards.
   This could come handy if a solar storm or an EMP attack would kick out the whole electricity grid. Of course I’d have to reserve spare cables and electronics in faraday cages..
   What do you think?

   Engineer775 is a cool guy. I need to get me one of those. I didn’t even know that you could do that. Cool stuff.

   Double D and Robert –

   I am doing some research on these – I know parts can be purchased on Amazon.

   Will post my findings.

   many years ago I saw a ceramic ring of thermocouples which were put on top of a stove or gas ring that charged batteries while you made tea or cooked, to run your transistor radio. nothing new here just better technology & a more efficient way of doing it.

   Here’s a website for TEGs: http://www.tegpower.com/index.html Note – I’m not associated with them in any way, nor have I purchased any of their products. I got the link a few weeks ago from another survivalist website, and thought the idea to be very interesting (and I still do). You can power stuff or charge batteries at night or when the sun isn’t shining much – only temperature differential is needed. Think of when you cook, inside or out, how much waste heat there is. With the most frequent use of a TEG, on a woodstove, you’re talking about a fuel source that is renewable, plus there’s lots of scrap around. Given the need for redundancy, this is a great backup to solar, or even a complete subsititute (because you can also put the TEG on a sheet of metal sitting in the sun – it’ll produce power, just not as much as sitting on a stove.
