No, I learned what I needed to with the first build. Now I will make a much larger more substantial one. Probably won't get around to it until next winter.
How much power are you wanting to generate?
Basically as much as I can from whatever I end up building. 2-3kw seems realistic with intermittent usage. It's definitely one of those projects where it's too hard to figure anything out without just trying stuff and learning as I go. So many variables involved...
I did some reading about it last winter and came to a similar conclusion. I'm curious about how much wood it consumes per kw hr produced.
